Dimensional and Physical Properties of Cotton/Spandex Single Jersey Fabrics

Abstract

In this study, the dimensional and physical properties of cotton/spandex single jersey fabrics are investigated and the results compared with fabrics knitted from otton alone. The loop length and amount of spandex are usted to determine the dimensions and properties of the knits. It is apparent that as the amount of spandex increases loop length values remain nearly the same and the course and wale spacing values decrease. Further more, because spandex-containing fabrics tend to tighter, the weight and thickness of the fabrics are higher but air permeability, pilling grade, and spirality are lower.

Dimensional Stability of Core Spun Cotton/Spandex Single Jersey Fabrics under Relaxation

“…In other words, they are more or less independent of yarn and fabric parameters [2,4,5,9]. Hence, CO/SP single jersey structures gave lower intercepts than CO structures in three relaxation stages, which implied that CO/SP single jersey structures could reach a more stable and quickly relaxed state than CO structures, as given by other previous works [1,2,4,5]. The reason for this would be that due to their yarn elastic recovery properties, stitch shape changes quickly becoming a stable state with minimum yarn energy level.…”

“…The reason for this would be that due to their yarn elastic recovery properties, stitch shape changes quickly becoming a stable state with minimum yarn energy level. Further, we have found that in considering the fabrics with same tightness factors, loop length variations at three relaxation stages were mostly below 3 % for both CO/SP and CO single jersey structures [1]. Thus, Table 4 gives the increasing percentages (%) of CPC and WPC values between relaxation treatments.…”

“…This weight was good enough to remove crimp in the unraveled yarns [1]. All the relaxation treatments were carried out according to the ASTM D 1284-76.…”

“…However, under full relaxation condition, effects of yarn and fabric parameters on a knitted fabric become a minimum energy condition and the stitches give a predictable geometrical configuration [1-7]. 1 Thus, resiliency force and yarn frictional force acting on interlacing points are major forces which affect the relaxation behavior of knitted fabrics [1]. Regarding this, spandex with higher elastic recovAbstract In this study, dimensional stability of core spun cotton/spandex single jersey structures with high, medium and low tightness factors were experimented under dry, wet and full relaxation conditions.…”

A neural network system for designing new stretch fabrics

“…Other woks [15][16][17][18][19][20][21] have studied the effect of some single factors on comfort stretch properties. These properties are influenced by the finishing treatment, the amount of elastane, yarn count, yarn twist, yarn composition, fabric's structure and the operating parameters (gauge, loop length, ….…”
