Method of manufacturing an elastic fabric comprising spandex of circular knitting and hard yarns.

摘要

A method of manufacturing a single jersey fabric circular knit (62) in which bare spandex yarn (12) of 17 to 33 dtex is plated with one or more hard yarns spun or continuous filament (14) or mixtures thereof, with yarn count from 35 to 85, and wherein the (the) thread (s) of spandex and hard (s) are vanisados ​​in every knit course to produce the single jersey fabric circular knit ( 62) with a cover factor of 1.3 to 1.9, wherein the method comprises: controlling the stretching on the spandex feed so that the spandex yarn is drafted no more than 100% elongation of its original length when knit to form the single jersey fabric circular (62) knitting; and finishing and drying (70) of the knitted fabric while maintaining the fabric at a temperature below that temperature required to heat set the spandex.
