Mechanism for Stretch and Recovery Properties of Certain Stretch Fabrics1

Abstract

The crimp in all-cotton, nylon, and polyester/spandex core stretch fabrics was ex amined by physical tests and by photographic enlargements of yarns and fibers removed from the fabrics. Measurements of total crimp and crimp due to yarn crossover indicate that yarn crossover crimp, external yarn crimp, has a major influence on the stretch and recovery properties of the comfort stretch fabrics having less than 30% stretch. Hysteresis curves show that faisetwisted nylon is significantly changed by weaving and subsequent finishing treatments. Nylon yarns raveled from stretch fabrics and filaments removed from the yarn show no evidence of residual effects of fatsetwisting if the fabric has less than 30% easy strech. The limited data obtained in this study indicate that interfiber friction may play a significant part in the stretch and recovery properties of all-cotton stretch fabrics. These data also suggest that fabric design and processing procedures that promote crossover yarn crimp are the areas most likely to improve the stretch and recovery properties of a comfort stretch cotton fabric.

Compression Garments for Medical Therapy and Sports

“…A study conducted by Senthilkumar et al [74] found that, at different extension levels, spandex-plaited cotton fabric has better dynamic elastic recovery than spandex core cotton spun fabric. In another study, Cooper et al [75] tested the stretch and recovery properties of different stretch fabrics with all-cotton, nylon, and polyester/spandex core yarns and indicated that yarn type and inter fiber friction may play a significant part in the stretch and recovery properties. Research studies also indicated that elastic recovery depends on the compression force provided, the length of time that the force is applied for, and the length of time that the fabric is allowed to recover [2].…”

Shapeable Stretch Textiles via Simple Weaves for Seamless Woven Fashion

“…Elastic materials are versatile for improving textile properties and solving certain issues of comfort and fit. Previous studies have revealed the shrinkable characteristics of stretch fabrics from a perspective of physical or mechanical performances [8][9][10]. The results indicated connections between tightness of structures and elastic shrinkage.…”

3D Seamless Woven Fashion Based on New Concept and Technology

“…Two parts in patterns design are individually decorative motifs or graphics, and allotted colours. Additionally, selecting and arranging yarns comprise four main factors: types of materials, thickness, smoothness, and colours (Cooper et al, 1965;Grosicki, 1977, Adanur, 2001Grosicki, 1975).…”
