Dyeing process of cashmere with reactive dye and acid dye

This article gives some reasonable dyeing process conditions of reactive dye and acid dye including the pH value,dyeing temperature and builder measure based on many experiments,which make great guidance to practical production of enterprises.Practice indicates that reactive dye is economical dyeing technology,it is easy to operate and has high fastnesses,especially wet fastness,which makes it becomes one of the best choices to replace metallic dye used for wool fiber.The affinity of acid dye to protein fiber increases along with molecular weight of dye.According to different condition,3 dyeing methods can be implemented in actual production,strong acid bath,weak acid bath and neutral bath.
