What are the unique and desirable characteristics of flax? What is Ramie known as? Give some the properties of Ramie C- True / False Cotton can blend with many fabrics The quality of cotton depends on terms of grade and character Low resiliency is a part of the main limitation of flax otton can’t be used in blends with Ramie D- Vocabulary Cotton has a _ of properties: pleasing appearance, comfort, easy care _ refers to the color of the fiber and the absence of dirt Color of _ is ranged from white to yellow The main limitation of flax is _ Ramie is also used in _ with cotton II Grammar The present simple in passive form Am Is Are + past participle 10 Unit 7: Knowledge about Fabrics Fabrics are used in apparel, furnishings and many industrial products Fabrics are made from a wide variety of starting materials: solutions (films and foams); fibers (felts, fiber webs or non-wovens); yarns (braid, knits, laces, woven or knitted) All woven fabrics are made with two or more sets of yarns interlaced at right angles to each other The yarns running in the lengthwise direction are called warp yarn or ends, the yarn running crosswise are called filling, weft or picks Fabric names are based on the end use (Hopsacking are bags for collecting hops; sacking Cheesecloth to wrap cheeses), on the town in which the fabric was woven (Bedford cord from New Bedford, Massachusetts; Calico from Calcutta, India; Chambray from Cambrai, France; and Shantung from Shantung, China) or on the person who originated that fabric (Batiste for Jean Batiste, a weaver and Jacquard for Joseph Jacquard) Through the names of fabrics, we can know a lot of informations belonging to the fabric: the type of fabric (woven or knitted); the weight (light, medium or heavy); material for yarns (cotton, silk, wool or man-made fibers: staple or filament yarn); interlacing patterns (plain, twill, satin, dobby or Jacquard) and other general characteristics (pile, luster, pliability, wrinkles…) I Vocabulary and terminology A - Keyterms and textile terminilogies fabrics:vải apparel: quần áo furnishings: vải trang trí film: màng (Lớp mỏng phủ bên trên) foams: bọt (lớp mỏng xốp, bọt) fibers: vải braid: băng vải knits: đan, d t kim laces : dây giày, ren woven : thuộc vải d t thoi knitted : thuộc vải d t kim sets of yarns: lớp sợi warp yarn or ends: sợi dọc filling, weft or picks: sợi ngang staple or filament: sợi ngắn, sợi liên tục plain, twill, satin :d t trơn, d t chéo, d t vân đoạn luster , pliability, wrinkles: độ bóng, gấp đ ợc, nhăn felts: da, nỏ (xơ kh ng đan mà ép vào cán ph ng) webs: màng (vải màng mỏng) non-wovens: vải kh ng d t yarns: sợi cheesecloth: vải bọc mát bedford: dây chằng (loại dây thừng nhỏ) hopsacking: vải may bao đựng lúa calico: vải ca-li-co, vải b ng chambray: vải ca r shantung: lụa trung quốc batiste ;

underwear, hosiery and baby blankets, especially sportwear The first knitting machine was invented in 1589 by Reverand William Lee of England In knitting process, needles are used to form a series of interlocking loops from one or more yarns or from a set of yarns There are two types of knittings: 1/ filling or weft knitting and 2/ warp knitting 1/ In filling knitting the yarn is carried back and forth (or around) and under needles to form fabric Yarn runs horizontally in the fabric In warp knitting, a beam is set into the machine and yarn sets are interlooped to form a fabric Yarn runs vertically in the fabric Typical fabrics from filling knitting are: single jersey, or plain jersey; jersey (for single filling knits) End- uses: underwear; hosiery; shirts; T-shirts; dresses; sweaters Rib, Interlock (for double filling knits) End-uses: Knits having same appearance face & back; hosiery; seamless hose; collars; trims 2/ Warp knitting provides the fastest means of making fabric from yarns It has been said that warp knits combine the best qualities of both double-knits and woven fabrics Warp knits tend to be less resilient and lighter weight than filling knits It is a process of making fabric in flat or sheet form using one or more sets of warp yarns that are fed from warp beams to a row of knitting needles extending across the width of the machine Typical structures of warp knitting are: Tricot; Rashel Main end-uses; Simple fabrics for outerwear, underwear, hosiery, upholstery, carpet, and nets (fishing net, mosquito-net) Keyterms and textile terminologies Knitting: d t kim interlooping: đan vòng vào set of yarn : lớp sợi sweaters: áo len underwear: đ lót shirt;T shirt;
