Problems solved by technology

[0005] However, the appearance of SORONA fiber is a spiral spring type, which is relatively fluffy, and the fibers are easy to condense into agglomerates, forming neps, and the spinnability is poor
During the production of the blowing and rolling machine, the concave and convex rollers are easy to block and difficult to pass through, so the blowing process is difficult to roll

Abstract

The invention provides a SORONA fiber spinnability preprocessing method, which can improve the spinnability of the SORONA fiber, so that the spinning becomes possible. The technical flow process is simple, and the processing cost is low. The method comprises the following steps that (a) liquid wax and water are mixed and uniformly stirred according to a mass ratio being 1:9; (b) the SORONA fiber is subjected to bale breaking and uniform spreading; (c) the mixing liquid obtained in the step (a) is uniformly sprayed onto the SORONA fiber, and in the step, the mass ratio of the mixing liquid to the SORONA fiber is (0.5 to 1.5):1000; (d) a plastic film is used for covering the SORONA fiber, and the heat insulation is carried out for at least 24 hours under the condition of 25 to 30 DEG C. In the steps (b) and (c), the relative humidity of the work environment is maintained at 55 to 60 percent, and the temperature is maintained at 25 to 30 DEG C.

Description

technical field [0001] The invention relates to textile technology, in particular to a spinnability pretreatment process of SORONA fiber before spinning. Background technique [0002] SORONA polymers are made from two main raw materials, 1,3-propanediol (PDO) and PTA (or DMT). Among them, PDO is its key raw material, accounting for 37% of the total raw materials. PDO can be produced through petrochemical processes, and DuPont of the United States has successfully used the method of SORONA sugar fermentation to efficiently produce the PDO required for the production of SORONA, thus revolutionizing the chemical fiber field and injecting a new concept of environmental protection. [0003] DuPont SORONA can give fibers and fabrics a soft feel, comfortable stretch and recovery, easy dyeing at room temperature and pressure, bright and lasting colors, and chlorine / ultraviolet resistance and stain resistance. It can be widely used in the development of various clothing fabrics: fr...
