Vorspann 23.10.2008 Preface 9th German Edition 15:59 Uhr Seite This is a vocational book, directed primarily at students of the clothing industry: cutting, sewing, and assembly for fashion and mass markets However, it will also be found useful in courses for managers and technologists, and as a general reference work A key feature of the book is its concise and compact design – a prerequisite for summarising such a wide range of material in a single volume Each page is complete in itself Particular emphasis has been laid on providing a simple layout and straightforward language, which students will find easy to grasp Numerous colour diagrams are an effective aid to the comprehension of some of the more difficult topics These coloured illustrations are a particularly useful feature of the chapters on Fabric Descriptions and the History of Clothing The book is organised largely according to the different technological sectors, but teaching requirements have also been kept in mind There are eleven chapters: Fibres, Yarns, Fabrics, Textile Finishing, Fabric Descriptions, Leather and Fur, Clothing Manufacture, Organisation of Clothing Manufacture, Product Design, Product Groups, History of Clothing The arrangement of topics conforms to the educational guidelines and the current curricula for courses in vocational technology in the German Federal States An important objective of this publication was to present the extensive body of knowledge as a coherent whole At all stages, account is taken of the latest scientific findings and the practical experience of the industry, as well as any relevant DIN standards Improvements for the 9th Edition: The sections on Textile Aftercare, Functional Clothing, Ecology, Seam Types, Health & Safety, and Fusing have been rewritten or extended according to the latest technical developments Many illustrations have been enhanced by the use of colour or changed to reflect current fashion trends We would like to give special thanks to the companies and associations listed on page 304 for their assistance in the clarification of questions and for the provision of pictorial material We are especially indebted to Sonja Langer-Korsch and Susanne Kolb-Wachtel (leather and fur), and Hannes Döllel (fashion drawings) for their helpful suggestions Many clothing companies today employ offshore manufacturing Therefore, it is useful to note that “Fachwissen Bekleidung” has been translated into English (“Clothing Technology”) and from there into several other European languages Maybe this can provide some stimulus to intra- and extra-European communication via the language of technology The new generation will need competence in both language and technology to succeed in an era of global market competition We would welcome any suggestions for improving or supplementing the material in this book Metzingen, Summer 2007 Preface 5th English Edition Editor and authors “Fachwissen Bekleidung” is now in its ninth edition and has been a firm favourite in the Germanspeaking area of Europe since it first appeared in 1989 So far as we are aware, the book is unique in its scope and presentation, so it was perhaps natural that a demand should arise for an English-language version Although this English edition follows quite faithfully the general content and layout of the German, it is not always a precise translation There are several instances in the original where the treatment of the subject matter naturally has a distinctively central-European bias In the English, an attempt has been made to present a more international perspective Wherever possible, ISO or ASTM standards have been referenced rather than DIN For an international readership, there is always the problem of whether to use British or North American terminology For this edition, wherever there is a conflict between the British and American traditions, the British has generally been selected, although the American is often acknowledged and occasionally preferred The German approach to Work Measurement has been retained, as a valid and comprehensive example of the technique Sections 9.6 to 9.9 of Product Design have been completely rewritten for the English edition Stockport, Autumn 2008 Allan Heap & Jill Stevens Cotton Technology International 001-007 Vorspann 23.10.2008 15:59 Uhr Seite Contents 3.2.5 3.2.6 3.2.7 3.2.8 Crêpe

Wool (2) 1.2 Natural Fibres Classification of Wool There are hundreds of different types and breeds of sheep They are classified according to their wool into five basic types: Fine, Medium, Crossbred, Long, and Coarse Wool Type Fine Medium, Crossbred Long, Coarse Merino, Rambouillet Southdown, Corriedale Lincoln, Romney, Karakul finest wools, 15 23 µm1) medium fine, 24 30 µm coarse, over 30 µm 50 … 120 mm 120 … 150 mm over 150 mm highly crimped normal crimp low crimp, straight Australia, South Africa, ex USSR Argentina, Uruguay New Zealand, Great Britain fine outerwear, knitted and woven, shawls, socks heavier, more robust, sporting clothing carpets, traditional furniture coverings Breed (examples) Fineness, Diameter Length Crimp, Waviness Sources (examples) Applications 1) µm = millionth of a metre = 10¯ m Apart from its fineness, length, crimp, and breed, wool can also be classified according to: • Shearing: Lambswool is from the first shearing, after six months, whilst Yearling wool is from the first or second shear after 10-12 months They are fine, soft, not very strong, with fine tips Six-month, Eight-month, Twelve-month wools are from sheep shorn at intervals of 6, or 12 months • • • Source: Australian, New Zealand, etc Cape wool is from South Africa; Shetland is typical coarse wool from Scotland • Recycling: Recovered Wool is wool that has been recovered mechanically by teasing apart production waste and secondhand clothing Recovered wool is damaged and is of low quality Extraction: Virgin wool is from living, healthy sheep or lambs Dead wool, Fallen wool is from sheep that have died from natural causes Skin wool has been taken from the skins of slaughtered sheep Spinning: Worsted wool is usually fine Merino, spun into fine, smooth, uniform, combed yarns The very finest and most expensive wools are made into extra-fine combed yarns designated as super 100s to super 200s Woollens are heavier, more voluminous yarns prepared on the woollen spinning system Carpet wool is long, coarse wools for carpet yarns protein macromolecule fibrils fibrillar bundles spindle cells scales Construction of the Wool Fibre bilateral structure The wool fibre is made of protein molecules (keratin) It is rather similar to human hair The long-chain protein molecules are formed into fibrils These combine into fibrillar bundles which form the mass of the spindle cells This construction gives the wool fibre an extraordinary elasticity The bulk of the fibre is made from two separate components These have different chemical constitutions, and they wind in a spiral around each other (bilateral structure) Moisture and temperature have different effects upon the two components, which swell to different extents, causing changes in the overall fibre shape It is the bilateral structure which causes the fibres to be crimped; finer fibres develop more crimp Heat and moisture can relax bonds between the protein chains The bonds are re-formed during cooling and drying, and this is the source of the good smoothing and shaping properties of wool Wool absorbs moisture (is hygroscopic) It can absorb about 1/3 of its mass of water vapour without feeling wet The moisture is released only slowly In spite of the strong affinity for water of the fibre interior, its surface is water repellent (hydrophobic) because it is covered by an extremely thin skin, the epicuticle This skin causes liquid water to roll up into droplets whilst allowing the passage of water vapour The scales on the fibre surfaces are capable of hooking onto one another to cause felting, under the influence of water, heat, and mechanical action 1: Model of the wool fibre 17 008-057 Kapitel 1 23.10.2008 15:28 Uhr Seite 57 Fibres 1.9 Ecology and the Textile Pipeline (3) Eco-labelling There is a demand from some consumer groups that textile labels should give information about any potentially harmful substances which may be contained in the product In various countries, governmental or private organisations have developed sets of criteria which can be embodied in a labelling scheme to satisfy these demands Typically, such labels guarantee that: no potentially carcinogenic dyestuffs have been used heavy metals are present in such small quantities that their concentration, when dissolved in perspiration, would be lower than the permitted levels for drinking water pesticides are present in concentrations lower than those permitted for foodstuffs formaldehyde shall not exceed a certain concentration the pH value is neutral or slightly acid (like human skin) textiles intended for babies and small children shall not release any dyestuff on contact with saliva Manufacturers or distributors of textile products can apply to these organisations for the right to use promotional and marketing materials (labels, hang tags etc.) subject to their products being included in a stringent testing regime • • • • • • Label Requirements Label Requirements Eco-Tex Standard 100is a label of the Hohenstein Test Institute, in Germany It guarantees that the concentrations of potentially harmful chemicals shall not be greater than certain published values Random samples are submitted to laboratory testing in one of a number of associated institutes GREEN-COTTON is a trademark of a Danish textile company specialising in environmentally friendly and socially responsible production The cotton is either certified “organic” or “sustainable” It is hand-picked and contains no pesticide residues The latest technology is used at all stages of manufacture to minimise environmental impacts The Eco-Tex Standard 1000 guarantees that the whole manufacturing chain, including working conditions, effluent disposal, environmental management, storage and transportation, all meet certain social and ecological standards NATURTEXTIL is a label of a German industry association It embodies strict ecological and social requirements throughout the manufacturing chain Only natural fibres or animal products that have been produced under strictly organic regimes are allowed Organic certification is required at all stages The Eco-Tex Standard 100 plus label guarantees that all products and operations of a given manufacturer, conform to the requirements of both the Eco-Tex 100 and 1000 standards MEDICALLY TESTED is a designation devised by a German research institute, based on a specific series of laboratory tests based on challenging human cells with an extract from the textile to give an assessment of “skin tolerance” Ecolog is a trademark of a German company that specialises in weatherproof clothing They have developed garments in which every component – fabrics, linings, membranes, zippers, padding, buttons – is made from pure polyester This means that at the end of its life, the garment can be reduced to polyester chips for re-use, e.g in bottles The EU Flower is a symbol created and supported by the European Union Any manufacturer may apply to use the symbol to identify products that comply with strict ecological and performance criteria The label is overseen, and the products are tested, by independent organisations such as Ecolabelling Denmark 57 058-070 Kapitel 2 23.10.2008 15:18 Uhr Seite 66 Yarns 2.5 Textured Yarns Texturing Flat continuous filament yarns made from thermoplastic (heat-formable) materials can be made permanently bulky by various processes This is called texturing and it results in: • increased volume • increased extensibility and elasticity • lower lustre • better thermal insulation due to the enclosed air • higher vapour permeability and moisture transport • softer and more comfortable fabrics Important Texturing Processes False-twist texturing filaments feed rolls heating zone twister delivery rolls Air-jet texturing yarn feed This is the most economical, and therefore the most common process The yarn is fed through a turbulent air stream, created by a jet Usually the air is cold but occasionally hot air or delivery rolls steam may be used The air jet causes entangled loops to be formed in the filaments air jet entanglement zone Stuffer-box texturing The yarn is drawn through a heated zone whilst a predetermined, high level of false twist is inserted followed by cooling and untwisting The heat softens the filaments and the deformation imparted by the twist is permanently set during cooling delivery rolls The resulting textured yarn is very bulky with permanent crimps and loops Can be used for non-thermoplastic filaments The yarn is fed into a heated chamber where it is compressed The zigzag deformations are permanently set by subsequent cooling The filaments can no longer lie close together so the yarn is bulky heated stuffer box The yarn is knitted into a tube on a circular knitting machine The knitted fabric is heat set and then unravelled The shape of the knitted loops is set into the yarn, which develops a bouclé (crinkle yarn) appearance Knit-deknit texturing knitting setting unravelling Types of Textured Yarns Whatever the texturing process used, textured yarns can be classified into three groups: Stretch yarns: Highly elastic yarns with a crimp extension of 150 to 300% Stabilised yarns: Yarns which have been given an additional setting treatment to reduce their elasticity and crimp extension Bulked yarns: Voluminous yarns with crimps and loops having normal extensibility and elasticity The term bulked yarn is often used generally to cover all continuous filament textured yarns and bulked staple fibre yarns High-bulk yarns Man-made staple fibres can also be made into bulky, voluminous yarns Such high-bulk yarns are usually made by blending acrylic fibres of high and low potential shrinkage During a subsequent heat treatment, the high-shrinkage fibres contract causing the other fibres to buckle A similar effect can be obtained by using bicomponent fibres Applications for Textured Yarns Stockings and tights (panty hose), swimwear, sportswear, outerwear, underwear, carpets, sewing and overedge stitching threads for extensible fabrics 66 071-098 Kapitel Kopie 23.10.2008 15:21 Uhr Seite 93 Textile Fabrics 3.3 Knitted Fabrics 3.3.3 Warp Knitted Fabrics (2) Multiple Guide Bar Fabrics For most warp knitted fabrics, the basic lapping structures are used in combination This means that more than one warp sheet and guide bar must be used Warp knitted fabrics have only a limited range of applications in apparel fabrics The most important are: leisure and swimwear, foundation and lingerie, extensible linings, laces, ribbons and trimmings In household textiles, warp knits are used for curtains, bed clothing and furnishings The widest use of warp knits is in technical fabrics Locknit Locknit (charmeuse) is a combination ×1 plain stitches On one of tricot and 2× side the fabric displays distinct wales of small face loops; the other side shows the zigzag formation of the underlaps It is made from filament yarns which give the characteristic lustre Applications: linings, interlinings, lingerie (Figures 1, 2, 3) 1: Locknit, schematic Warp Knitted Terry This is made with an extra warp sheet of pile yarns which are caused to form loops, bound into a ground fabric Applications include furnishings and bed sheets (Figure 4) Warp Knitted Plush, Velour 2: Locknit, face 3: Locknit, back In this case, the pile loops are cut to give a fleecy or velvet-like surface Applications include beach, leisure and sportswear, ladies outerwear (Figure 5) Raschel Net Nowadays, net fabric is almost always made on raschel machines It is a combination of pillar and tricot stitches Raschel net is most popular in bridal wear (Figure 6) 4: Warp knitted terry 5: Warp knitted plush, velour Raschel Lace Raschel lace fabrics are often made on a base of net fabric with a pattern formed from inlay yarns They are used for foundation and lingerie, bridal and formal wear, and as trimmings

or synthetic polymer to one side of the fabric, followed by fixation in a curing oven polymer blade fabric The polymer film can be applied directly to the fabric (Figure 1) However, if the fabric is an open one, or the material to be applied has a low viscosity, the liquid will first be applied to a carrier paper and then transferred from there to the target fabric (Figure 2) curing chamber 1: Principle of direct coating The coating imparts new properties to the fabric, which are a combination of the original material (woven, knitted, nonwoven) and the coating (polyurethane, polyvinylchloride) curing chamber fabric paper collection polymer paper Coated textiles (Figures and 4) have a wide range of uses from clothing to technical fabrics In clothing uses, it is advantageous if the coating is permeable to air and moisture vapour 2: Principle of indirect coating Applications • sporting, protective, working clothing; • highly-visible (fluorescent) clothing; • shoe uppers, leather cloth; • handbags and luggage; • furniture and automobile seat coverings; • bookbinding, maps, albums; 3: Coated fabric • window blinds, shower curtains, table covers; • floor and wall coverings; • conveyor belts, tarpaulins, awnings, air-supported structures, inflatable dinghies, textile roofing, etc 4: Protective clothing Lamination blade fabric Lamination is the superimposition and bonding of two or more fabrics, or a fabric with paper, film, or foam The bonding can be achieved with an adhesive (Figure 5) or by heat (Figure 6), whereby a polymer film or foam is melted onto the surface of one fabric and then the other fabric is pressed onto it (Figure 7) polymer fabric 5: Adhesive lamination flame heating fabric foam 6: Foam lamination 7: Foam laminated

various accessory items These have to be chosen in such a way that they complement the outer fabric both aesthetically, in terms of decoration, and practically, in terms of ensuring that the garment performs as expected in its intended end use The manufacture of ribbons, tapes, and decorations is similar to that of textile fabrics; weaving, knitting, braiding, or nonwoven techniques In many cases, different patterning elements are combined such as fibre and colour effects, structure and finishing The commercial names for ribbons often follow from the application or the structure, for example piping ribbon, velvet ribbon Decorative ribbons (trimmings) are also used for ornamentation Ribbons and Tapes Name Features, Properties, Applications Trimmings General name for a patterned, woven or knitted ribbon in cotton, silk, wool, or man-made fibre Scalloping, Rick-rack Narrow bowed, zigzag, or scalloped ribbon, plain or multi-coloured in cotton or man-made fibres for edge trimming

knits) Bespoke operations are divided along technical lines into men's tailoring, women's tailoring, shirtings, and underwear Comparison between Bespoke and Industrial Production Bespoke Clothing Production Industrial Clothing Manufacture • The clothing is made for individual clients, according to individual size and requirements Particular characteristics of the client, in terms of the body shape, can be taken into account during cutting and sewing • Production is geared to an anonymous, statistically and/or demographically and culturally defined target consumer group • The client selects the material and the design, from sample swatches and fabric collections The cut and the style is agreed by discussion with the tailor, before cutting begins • Bespoke tailoring involves a much higher investment of time for each garment, and is correspondingly more expensive than industrial manufacture However, the client is usually rewarded by a more individual design and a higher quality of material and workmanship • Cutting patterns and sizes are based on standard size charts, derived from large numbers of measurements • Garments are produced in a limited range of sizes Standardised cutting and making procedures mean that all garments have the same shape; allowances for uncommon body shapes can not be made • The consumer has the choice between a wide range of different garment styles but has no direct influence over their design and cut • Large-scale manufacturing techniques allow a wide range of garments to be produced in a fraction of the time required for bespoke tailoring of individual items Product Groups with Examples of Product Types (Apparel Fabrics) Menswear, Boyswear Womenswear Children's wear Workwear, Sportswear jackets trousers suits

organise the production of garments, according to the type, the quantity and the diversity of products to be made The number of items to be made and the rate of delivery of these items distinguish individual production, batch production and mass production Individual Production With individual production (making through) each product is made only once The system requires highly skilled, experienced operators and versatile machinery Example: made-to-measure costume Batch Production Batch production is used for larger, though fixed quantities of identical articles either for stock or to order Examples: blouses, skirts Mass Production Mass production means that large quantities of identical products are made continuously The high utilisation of machinery and labour allows a high level of automation and specialisation Examples: T-shirts, work trousers Sharing a job of work between several people is called division of labour Quantitative division is where the required number of whole items is shared (with each person doing the same work) Qualitative division is where the work required for each item is divided into smaller operations (each person performs a different operation) Production Organisation Systems 1: Straight line system with hanger transport 2: Bundle assembly with wagons The synchronised, or straight-line system is suitable for large volume production (mass production or large batches) As the name suggests, the work flows in a straight line through a series of workstations, each of which is synchronised to the next by ensuring that the time spent at each station is exactly the same This represents an extreme form of the division of labour The system requires that each individual step in the assembly of the product has to be analysed carefully and the steps distributed in a balanced way over the available work stations Each operator then performs exactly the same operation(s) over and over again on the identical parts of successive garments Detailed work plans have to be drawn up to facilitate this balancing of the line Advantages of the synchronised line system include short distances between stations, low volume of work in process, precise planning of production times, highly visible production progress and predictable production quantity Disadvantages include the need for intensive detailed preplanning, high cost of style changes, sensitivity to disruption by production difficulties or absenteeism, and the dependence of productivity on maintaining a strict rhythm of work The progressive bundle system is a way of avoiding the rigidity and some of the disadvantages of the synchronised line system Machines and operatives are organised into sections, each of which specialises either in the production of a major sub-component (collars, cuffs), or the assembly of two or more sub-components Within and between sections the work is balanced according to the time required for each sub-function The combination of small bundles and a line system provides the best solution to the problems of frequent style changes, small lot sizes, and short delivery deadlines Materials transport systems (Figures and 2) distribute the work in progress among the different workstations 205 202-222 Kapitel 8 23.10.2008 15:26 Uhr Seite 212 Organisation of Clothing Manufacture 8.9 Production Management (1) Production management provides all of the tools that are required for the smooth and economic operation of manufacturing processes It regulates the interaction in space and time between people, equipment, information and resources to achieve the objectives of the manufacturing system (page 209) A principle concern is the flow of work in progress and information The following tasks are of particular significance • Determining the time sequence of the required processes • Timely provision of materials and equipment • Timely provision of information Every manufacturing company has a production program to follow For a garment maker, the production program is embodied in the collection plan The collection is the range of products that will be manufactured for marketing in a particular season (page 224) The Production department co-ordinates the development of new products, the procurement of materials and their processing, and the control of quality throughout manufacture The Processing (Making-up) department is responsible for the processes that complete the work to be done It is responsible for production planning and control Data Exchange and Data Formulation Co-ordination between departments, sections and processes is mediated by the exchange of data (information) Data are supplied in the form of detailed work instructions and process-dependent technical information Data have to be documented This can be done via a company computer network and also by the use of standard company forms The way that data are transmitted in a particular company will depend on its structure, its level of technology, the type and range of its collections and other factors A wide variation is possible Task Development of new products •

Quality Levels Marketing is a collection of activities that include market research, consumer surveys, and customer service The objective is to arrive at a collection of products for sale in the future and then to promote this collection in the market The ultimate goal is a collection that can be produced for minimum risk and maximum return Target Groups A target group is an identifiable sector of consumers with broadly similar characteristics, such as fashion consciousness, buying habits, types of shops used, brand awareness, brand loyalty and quality requirements A target group can be defined according to the following criteria Attitude and Lifestyle Womenswear Menswear Fashion Awareness and Expectations Womenswear Menswear Anti-fashion, no demands Trendy fashion follower Avant-garde Avant-garde Nonconformist Younger, confident, demanding Fashion conscious Young fashions Prestige oriented Untidy youthful Jeans type Jeans type Not to be tempted Older, demanding, fashion

Formal Middle of road Middle of road Bargain hunter Bargain hunter Young, trendy Quality Level Quality level is the other factor that determines the market sector towards which a collection will be aimed The quality level defines the rank of the product in the total range of offers in the market, so far as its design content and workmanship are concerned The following factors, for example, have an influence • Fabric quality • Workmanship in the interior parts • Style and Fit high • Fashion content • Precision of assembly • Range of sizes and number of pieces The following quality levels can be distinguished Exclusivity Designer High quality Designer quality characteristics include unique designer labels, small numbers per style, the most exclusive fabrics – often with in-house designs – extreme fashion leaders, avant-garde designs Upper middle High quality or Model fashions are characterised by very high levels of workmanship, exclusive designs and detailing, small series production, limited size range, fashionable The Upper middle level uses good quality fabrics, provides optimum fit, and follows the latest fashions in style and colour Middle The Middle level has strict price constraints, a comprehensive size range, but a limited range of styles Bottom, discount store low The Bottom or Discount level has large quantities of limited styles Fabric quality and workmanship are
