Manufacturing process for colored polyester-nylon composite superfine fibre

Abstract

The invention relates to a color polyester cotton compound superfine fiber manufacturing process. The color polyester cotton compound superfine fiber manufacturing process is characterized in that the manufacturing process comprises the following steps: firstly, the raw material polyester fiber and the nylon are sliced; secondly, the sliced polyester fiber and the nylon are dried with a crystallization dryer; thirdly, coloring material particles are added to the crystallization dryer through a color printing machine to perform drying; fourthly, the dried polyester fiber slices, the nylon slices and the coloring material particles are melted with a screw rod extruding machine; fifthly, the melted body volume is controlled through a spinning finish measuring pump and a spinning measuring pump; sixthly, compound spinning is performed on a conjugated spinning machine; seventhly, after spinning, the fiber is rolled into a spinning cake through an automatic high speed winding machine; eighthly, the winded spinning cake is placed in a balancing chamber to be balanced; and ninthly, texturing is performed to the balanced spinning cake on a common texturing machine. Compared with the prior art, the process has the advantages that the coloring can be directly realized during the spinning process, the color fastness, the sunlight fastness and the thermal fastness are good, the gloss is even, and the color rendering property is good.

Description

technical field [0001] The invention relates to a manufacturing process of colored polyester nylon composite superfine fiber. Background technique [0002] At present, the existing colored polyester-nylon composite superfine fibers in China are natural polyester-nylon composite superfine fibers, and the color is realized in the subsequent dyeing process after the fibers are woven. It can only be dyed into one color, but cannot dye various patterns according to product requirements, which limits the development speed of new products to a large extent, and also pollutes the environment such as waste water during the dyeing process, and the color is uneven and the color development Poor property, chromatogram and color fastness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manufacturing process of colored polyester-nylon composite superfine fiber with fast color, uniform color and good color rendering in view ...
