Problems solved by technology

However, due to the relatively tight molecular structure of polyester, high crystallinity, low dye uptake rate, and large color difference of the product, and due to the influence of high temperature during the finishing process, the effective components of the fiber function will be lost, making the performance of the product unstable. And its production process consumes a lot of energy and causes great environmental pollution.

Abstract

The invention discloses a method for producing differential terylene color yarns. The method comprises the following steps of: pre-crystallizing a functional polyester chip at the temperature of between 144 and 146 DEG C for 20 to 60 minutes, and drying at the temperature of between 149 and 151 DEG C for 4 to 6 hours, so that the moisture content of the dried functional polyester chip is less than or equal to 17 ppm; and drying masterbatches for 1 to 2 hours, mixing the dried masterbatches and the dried functional polyester chip fully, adding the mixture into a screw extrusion spinning machine, spinning by using a spinneret plate of the screw extrusion spinning machine, winding and dropping into a bucket, and processing to obtain the differential terylene color yarns. In the method, the masterbatches are added into the functional polyester chip to be spun into the color yarns, the masterbatches and the functional polyester chip are mixed uniformly in a mode of dynamic mixing or static mixing in a screw extruder, and the color yarns are produced through the spinneret plate. By the method, the color fastness and stability of the products are improved, the production cost is reduced, and environmental pollution is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical fibers, in particular to a production method of functionally differentiated polyester colored yarn. 【Background technique】 [0002] Differentiated fibers refer to chemical fibers that are innovative to conventional types of chemical fibers or have certain characteristics. Differentiated fibers can improve production efficiency, shorten production processes, save energy, reduce pollution, and increase new textile products. Differential fibers are mainly produced by chemical modification or physical deformation of chemical fibers, which include modification in the polymerization and spinning process and deformation in the spinning, stretching and deformation process. There are many varieties of differentiated fibers, including special-shaped fibers, superfine fibers, composite fibers, colored fibers, high-shrinkage fibers, high moisture absorption, high water absorption fibers, antistatic and co...
