Abstract
It has been reported that natural dyeing is impossible without pre-treatment with metal mordanting agents. However, pre-treatment with chitosan, which has high affinity to natural dyes, could result in an excellent dyeing with various natural dyes. In this study, three treatment methods were employed; 1) Using PET without any pre-treatment (Method 1) 2) Using PET with chitosan acid solution pre-treatment (Method 2) 3) Using PET with chitosan pre-treatment and subsequent crosslinking using citric acid (Method 3) Method 2 and 3 enhanced the Cochineal dyeability remarkably compared to Mehod 1. Washfastness was also enhanced, and moisture content, static property, abrasion resistance, and fabric hand changes were investigated.
