Abstract

The relationship of Count, GSM (Gram per Square meter), and Stitch Length, Shrinkage%, spirality% and pilling are discussed by this paper among Pique, Lacoste and Jersey knit structures with or without Lycra “3% - 5%”. For this research, we used different knitted structures, yarn count and stitch length and for finding data different types of m/c are used which are discussed later. This study is based on finish GSM of Pique, Lacoste and Jersey Knit Fabrics where various kinds of yarn count, GSM and Stitch length are used to justify the experiment. The relation of count and Stitch length with GSM is inversely proportional. When count and Stitch length increases, GSM decreases which is proved through this paper by using both the expected and experimental data. For writing this paper we have distinguished both the theoretical as well as practical implications from the industry and tried to find out adjustable points of fabrics Count, GSM and Stitch Length along with Shrinkage%, Fabric width, Spirality. This paper provides a reliable result which will help selection of count, GSM and Stitch length for making of Pique, Lacoste and Jersey knit fabrics with or without Lycra maintaining the Shrinkage%, spirality%, pilling grade in an acceptable limit. This paper logically shows that GSM, shrinkage and spirality vary when structure, yarn count, and stitch length vary.

Highlights

Knitting is a method of creating fabrics by transforming continuous strands of yarn into a series of interlocking loops, which are formed from a single yarn or from many yarns, each row of such loops hanging from the one immediately preceding it with the help of needles [1]

Summary

Introduction

Knitting is a method of creating fabrics by transforming continuous strands of yarn into a series of interlocking loops, which are formed from a single yarn or from many yarns, each row of such loops hanging from the one immediately preceding it with the help of needles [1]. In a warp knitted structure, each loop in the horizontal direction is made from a different thread and the no of threads used to produce such fabrics is at least equal to the number of loops in horizontal raw. For the specification of knit fabrics count, GSM and stitch Length are mainly considered [5]. Weft knitted elastic fabrics are produced by the combination of cotton-spandex yarn in a circular knitting machine which have a great response and gain their original size and shape due to physical extension by any part of human body [6]. Knitted structures have a significant impact on the GSM, Shrinkage and spirality. Yarn count changes for producing specific GSM fabrics. More tight stitch length (than required) creates a hole in the fabric and is responsible for increasing shrinkage and spirality
