The influence of the cationic softeners on the structural and mechanical properties of differently pretreated cotton/elastane single jersey knitted fabrics

Abstract

In this study the effect of elastane and cationic softener finishing on properties of cotton and cotton/elastane single jersey knitted fabrics were studied, Samples od 100% cotton, elastane yarns in alternating courses (half plating) or in every course (full plating) were scoured, bleached or dyed with reactive dyes, finished or not finished with cationic softener in industrial conditions. Considerable differences in structural and mechanical properties of cotton and blends cotton/elastane knitted fabrics after different finishing stages were found. Elastane in blends increased the fabric weight, thickness, stiffness and decreased bursting strength. Cationic softener finishing increased fabric weight, thickness and bursting strength.

U ovom radu ispitivan je efekat elastanske prede i dorade katjonskim omeksivacem na svojstva pamuka i pamuk/elastan desno-levih pletiva. Uzorci su proizvedeni od 100% pamuène prede i platirani uzorci sa uvedenom elastanskom predom u svakom i svakom drugom redu.

Uzorci su iskuvavani, beljeni ili bojeni reaktivnim bojama i zatim doradivani ili nedoradivani katjonskim omeksivacem u industrijskim uslovima. Ustanovljene su zacajne razlike u strukturnim i mehanickim svojstvima pletiva od 100% pamuka i pamuka sa elastanom, nakon razlicitih faza dorade. Kod pletiva od pamuka sa elastanom povecava se povrsinska masa, debljina, krutost, a opada jacina prskanja. Tretman katjonskim omeksivacem povecava povrsinsku masu pletiva, debljinu i jacinu prskanja pletiva.
