Dyeing of polyester/cotton knits with HA type alkali-resistant disperse dyes

New dyeing processes of polyester/cotton fabric are launched using HA-type alkali-resistant disperse dyes,JX one bath bleaching and dyeing agent and JX reduction-clearing-free high-efficiency detergent,one bath one step process of peroxide bleaching and disperse and direct dyeing,as well as reduction clearing free one bath one step process of peroxide bleaching and polyester dyeing are carried out.Practical application shows that the new one bath one step process can eliminate several procedures of rinsing and steam heating and some peroxide bleaching assistants,and it features high production efficiency,energy-saving and cost reduction compared with the traditional three-bath-three-step process of bleaching,polyester dyeing and cotton dyeing.
