Problems solved by technology

[0004] The research on the dyeing of polylactic acid fiber and cotton blend is still in the exploratory stage. Due to the relatively high price of polylactic acid fiber, if it is dyed with disperse dyes from foreign companies, the cost is very high, which is not conducive to the promotion and application of domestic polylactic acid fiber. , how to dye it with domestic disperse dyes and auxiliaries to achieve the dyeing effect of similar foreign products and reduce costs is the biggest problem that needs to be solved at present

Abstract

The process of dyeing woven polylactic acid fiber / cotton blended fabric belongs to the field of textile dyeing technology. The process of dyeing woven polylactic acid fiber / cotton blended fabric has China produced disperse dye and assistant adopted and improved steps of desizing, boiling and rinsing, mercerizing and dyeing. The dyed product has bright colors, proper shade and high color fastness. The present invention is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing technology, and in particular relates to a dyeing technology of polylactic acid fiber / cotton blended woven fabric. Background technique [0002] Corn, grain and other agricultural products are used as raw materials, which are bio-fermented into lactic acid and then synthesized. Polylactic acid fiber not only has excellent physical properties and wearability, but also its waste can be completely decomposed into CO in nature. 2 and H 2 O, will not pollute the environment, so it has become one of the new environmentally friendly fibers that the industry pays attention to. The characteristics of "plantable and easy to plant" raw materials of polylactic acid fiber also just meet people's pursuit of nature, green and environmental protection. Therefore, polylactic acid fiber is recognized as an excellent "green fiber" in the 21st century. [0003] Polylactic acid fiber has silky luster, good sk...
