Abstract

The invention relates to a fiber manufacturing method, wherein, the method comprises the following steps that: a dry master batch melt and a spinning chip melt with the weight percentage of between 10 and 35 percent to between 65 and 90 percent enter a spinning extruder to be evenly mixed under the protection of nitrogen, and the temperature is 8 to 10 DEG C lower than that of the prior fiber spinning; the mixture passes through a melt filter and reaches a spinning manifold, and the temperature of the manifold is lower than a temperature of between 5 and 8 DEG C used by the prior fiber; the spinning is adjusted on a spinning pack; the spinning cooling is performed; oil and water are added to spin multi-functional pre-oriented fiber, multi-functional elastic fiber or multi-functional full draft fiber; an internal draft false twisting heating texturing method is adopted to process POY into DTY , the oil and the water are added again, the weight accounts for 3 to 3.5 percent of the DTY, thereby producing product DTY, namely multi-functional nanometer antibacterial elastic fiber. The fiber produced by adopting the method has a plurality of functions.

Description

technical field [0001] The invention relates to a fiber manufacturing method and belongs to the technical field of textiles. Background technique [0002] With the development of modern industrial technology and the improvement of people's living standards, the technology of the textile industry is also advancing with each passing day. After differential fibers, synthetic fibers with multiple functions have emerged in the market in recent years. There are many single-function fibers such as far-infrared emitting fibers, negative ion emitting fibers, ultraviolet blocking fibers, and antibacterial fibers. With the improvement of people's life, the increasing awareness of health and the emergence of various functional fibers, people no longer just keep warm and cover their bodies in clothing, but expect multifunctionality. Therefore, fiber products with health care functions are more and more popular. Fabrics woven from functional fibers are very popular in the market. With...
