Evaluation of chitosan based pretreatment for cotton and linen dyeing with direct dyes and reactive dyes

Cellulosic materials like cotton and linen are excellent textile substrates for dyeing with reactive direct dyes. Due to their cellulosic nature, exhibit good affinity towards This is the reason washing rubbing fastness. Chitosan a bio-based polymer gained by deacetylation of chitin. In contrast cellulose, chitosan exhibits also amino functional groups. The purpose this paper evaluate if based pretreatment can lead different properties. After pretreatments, color properties determined CIEL*a*b* indices. fastness in dry wet conditions measured. Even actual study no positive effects were chitosan, results could be utilized future research develop other treatments implemented chitosan.
