Improving the dyeing effect of sisal fibers through pre-treatment methods
In order to meet the market demand and develop more sisal dyeing products,the process of sisal dyeing needs to be improved.This paper first designs three pre-treatment methods of sisal,namely,hydrothermal treatment,acid treatment and alkali treatment,and then adopts the same reactive dye dyeing process to dye sisal fibers,finally,tests the dyeing effect of the finished products.Through comparison,it is found that the dyeing rate and color fixation rate of the alkali-treated sisal fibers are high,and the color depth of the finished product is significantly improved,which is suitable for application in production.
