Low-temperature and efficient crosslinking of lyocell knitted fabric with an eco-friendly diepoxy agent for fibrillation resistance

Abstract

Lyocell ber is a low-carbon ber and has many remarkable characteristics, which makes it a good application prospect in the future. However, lyocell ber is prone to brillate under wet friction conditions. This work aimed to prepare lyocell fabric with low brillation tendency by an eco-friendly, low-temperature and e cient crosslinking method. Here, the N 1 , N 6 -bis(oxiran-2-ylmethyl)hexane-1,6-diamine crosslinked with lyocell fabric to achieve brination resistance. The dosage of crosslinking agent, pH values of crosslinking solution, temperature, and time on brillation tendency of lyocell fabrics were investigated. Scanning electron microscopy was used to observe brillation tendency, which showed that the lyocell fabric impregnated in 5% EH and pH = 10 solution at 40°C for 30 minutes had almost no micro brils. In addition, the results showed that the whiteness, mechanical property and dyeing performance of crosslinked lyocell fabric were retained, and the wear resistance was enhanced. This study demonstrated a potential and practical application of this crosslinking agent to diminish the brillation of lyocell fabrics.
