Measurement of Fabric Shrinkage & Dimensional Stability Shrinkage Test: Shrinkage test: Testing time: After dryer or before compacting Equipment used: Shrinkage board ,shrinkage scale, measurement tape, scissor, washing machine, detergent Lengthwise shrinkage = (-ve) % Lengthwise extension = (+ve) % Test method : ISO 6330:2000 Shrinkage tolerance: ±5% The fabric is cut according to the shrinkage board... preferable to hand wash resin treated rayon fabrics Compressive Shrinkage Rubber Belt Principle Belt Principle for Imparting Mechanical Shrinkage for Knits Shrinkage Remover By Morrison Shrinkage Control of Knit Fabrics The Micrex Process For open-width knit fabrics based on cavity type overfeeding Construction Shrinkage Construction Shrinkage: After a cotton fabric is constructed on a knitting machine... various specifications including shrinkage The type of shrinkage measured at this point is defined as construction shrinkage Construction shrinkage is defined as the amount of dimensional change in a fabric based solely on the construction variables used to create the fabric It is measured after fabrication but before subsequent processes Processing Shrinkage Processing Shrinkage: All processing steps... board Then the fabric is washed by washing m/c with PCLF for 60 min at 40 Then the shrinkage% is determined by the shrinkage scale Shrinkage Test: Determination of dimensional change in washing and drying Determination of dimensional change in washing and drying: International Standard ISO 5077 First edition- 198 4-1 2-0 1 Principle: The specimen is conditioned in the specified standard atmosphere and... determine directly the % dimensional change (shrinkage) in all types of fabrics 2 Fine calibrated Shrinkage Template with 18" x 18" & 10" x 10" benchmarks length-wise & width-wise 3 Two fine tipped black & yellow fabric markers are supplied for accurate marking on light & dark color fabrics 4 Calibrated scale to evaluate shrinkage & stretch directly Up to 15% How Shrinkage Template & Scale works? 1 The... the method It can either be Line Dry or Flat Dry or Tumble Dry Calculation for shrinkage percentage: To find the dimensional change read the Shrinkage/ Stretch on 3 points on the Wrap side and 3 points on Weft Side Calculation for shrinkage percentage: Shrinkage is determined as; Shrinkage % = (length of fabric before wash )-( length of fabric after wash))/ (length of fabric after wash) *100 Example, length... to the procedure specified in ISO 3759 Shrinkage Template & Scale is used for finding accurate Shrinkage in fabric and Garments 1 Shrinkage Template & Scale also measures the dimensional changes in fabrics after laundering, dry cleaning etc 2 Template and shrinkage scale made up of transparent polymer plate to apply standard pressure on test specimen Features of Shrinkage Template & Scale: 1 To determine... of the method It can either be Line Dry or Flat Dry or Tumble Dry To find the dimensional change read the Shrinkage/ Stretch on 3 points on the Wrap side and 3 points on Weft Side Get the mean value of wrap-wise and weft wise readings to get the Accurate Shrinkage or Stretch Working Procedure: Shrinkage Test Procedure: 1 Determine the original length and width dimensions, as appropriate after the specimens... knitting machine, are examples of stresses that may induce elastic shrinkage, which becomes a part of the construction shrinkage The stress in transporting of fabric in bleaching and dyeing machines as well as finishing operations will also induce elastic shrinkage Normally, the recovery from elastic stresses (realization of elastic shrinkage) is fairly spontaneous when these stresses are relieved,... processing shrinkage, which can be defined as the dimensional change that a process adds to or removes from the construction shrinkage of a fabric, and thereby changes the residual shrinkage accordingly Length and width dimensions are both affected, and the fabrics may either be stretched or consolidated Most often, the length is stretched and the width is reduced during wet processing Some of this shrinkage . 9 2"+/6+,@<##+ Rubber Belt Principle Compressive Shrinkage Belt Principle for Imparting Mechanical Shrinkage for Knits #7,#"# 2##'%3.96"6".#7,,'#79. *4)#"" <##+#9?26" <#"/5# 7. )*'+, - .
