Optimization of stretch and recovery properties of woven stretch fabrics

Abstract

Stretch woven fabrics are widely used owing to their comfortable properties such as formability, fitting to the human body and shape retention after wearing. These distinguishing properties are determined by stretch and recovery tests. The aim of this study is to determine the optimum elastane draw ratio, load and relaxation type for best stretch and recovery properties of woven stretch fabrics. An optimization model is developed to determine the optimum draw ratio of the elastane core in the yarn, load applied to the fabric and relaxation type for the best response variables of stretch and permanent stretch. The effects of the elastane draw ratio, load applied to the fabric and relaxation type on stretch and permanent stretch properties are found to be statistically significant according to analysis of variance results. Regression models are obtained to estimate the stretch and recovery properties for different elastane draw ratios and load levels. Additionally, the effect of the elastane draw ratio of the yarn on the fatigue properties of woven bi-stretch fabrics is investigated for dry relaxed and laundered states.

Süper Streç Denim Kumaşların Özelliklerine Dair Literatür İncelemesi

“…Tüm streç dokuma kumaşlarda olduğu gibi streç denim kumaşların streçlik ile geri toparlanabilme yetenekleri çok önemlidir. Buradaki streçlik özelliği kumaşın insan vücuduna göre şekil alabilmesini, geri toparlanabilme özelliği de yorulma davranışı sonrası estetik görünümü etkilemektedir [36].…”

Quality optimization of ring spun yarns produced from blends of regenerated cellulosic fibres with cotton and polyester

“…Desirability method makes use of an objective function, D(X), called the desirability function. This function reflects the desirable ranges for each response (d i ) and desirable ranges changes from 0 to 1 which corresponds least to most desirable and involves the use of a geometric mean of individual desirability [23][24][25]. For various responses and factors, all targets are combined as a desirability function.…”

“…Weights greater than 1 (maximum weight is 10), give more emphasis to the goal. Weights less than 1 (minimum weight is 0.1), give less emphasis to the goal [23]. Desirability curves for goal is maximum, minimum and within the range is illustrated in figure 6.…”

“…6. Desirability curves for goal is maximum or minimum [23] maximum level of tenacity, elongation and minimum level of unevenness, IPI and hairiness which importance of these are predefined in the numerical optimization process. From the line 1, if polyester/ bamboo blended yarn with 73.19%/26.81% blend ratio is used; overall desirability with the value of 0.859 will meet the goal.…”

Analyzing Some of the Dual-Core Yarn Spinning Parameters on Yarn and Various Fabric Properties

“…This study provides a better understanding the effect of sheath fibres, core filament and yarn finenesses on dual-core yarns. In addition, majority of the studies reported in the literature has focused on the usage of cotton fibre as a sheath fibre for core-spun yarns composed of single [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] and dual core filaments [1][2][3][4]. Present study was therefore undertaken to investigate the effect of different sheath fibre types on dual-core yarns.…”
