Exploration of CVC non Lycra elastic water soft and non ironing fabric technology
Currently,fabrics that have undergone non ironing treatment have a problem of becoming hard to the touch.To address this issue,the article designed a fabric finishing process and tested various indicators.The results showed that when the reed width was 176 cm,the mass concentration of caustic soda for finishing was 250-260 g/L,the overflow washing time was 45 minutes,and the dosage of setting softener was 20 g/L,the shrinkage rate of the fabric was between 0%and ﹣3.0%,the tear strength was not less than 2.0 lbf(about 8.9 N),the tensile strength was not less than 30.0 lbf(about 133.4 N),the flatness was not less than grade 3.5,the elastic elongation was not less than 15.0%,the recovery rate was not less than 55.0%,the residual elongation was not more than 8.0%,and the formaldehyde mass fraction was not more than 1.6×10-5,all of which met the customer's testing index requirements.The fabric is formaldehyde free,pressure free,and burden free,with advantages such as health,no ironing,and super flexibility.
