Dope Dyed Polyester Yarn is a high-tech textile dyeing and finishing technology in which colored fibers are produced by adding colorant before spinning during or after polymerization processing.

 

The traditional dyeing method is to dye the fibers by printing and dyeing methods after they are made into the fabric. Dope dyeing refers to the production method of producing colored fibers by adding colorant before spinning during or after polymerization processing. After more than 90 years of development, liquid dyeing technology has been widely used in Europe, the United States and Japan for synthetic fibers, which have been industrialized production of liquid dyed fibers including: polyamide, polyester, polypropylene, polyethylene, polyacrylonitrile and so on. The dyeing effect is superior, the process is simple, energy saving, especially suitable for large-scale production of fabrics according to the standard color number, can be used for military uniforms, uniforms, labor protection supplies, etc., in the automotive fabric, carpet industry, decorative cloth and other fields are also in great demand. In the long run, the stock solution dyeing will be increasingly concerned, it occupies a solid position in all the applications that require a high degree of dyeing uniformity and fastness, and has broad prospects for development.

 

 

Excellent effect, energy saving and environmental protection, shorten process flow, reduce chemical finishing, improve dyeing fastness.
