Problems solved by technology

However, the fiber prepared by this method is an internally added fiber, and the functional powder and masterbatch are blended and melt-spun, so most of the functional powder inside the fiber makes the utilization rate of the functional powder low and hollow. The fiber has the disadvantages of short service life and difficult processing

Abstract

The invention discloses self-heating polyester fiber. The self-heating polyester fiber is characterized by being prepared from a heating additive for polyester spinning, polyester fiber and master batches for polyester spinning, wherein the heating additve for polyester spinning is prepared from the following ingredients in percentage by weight: 0.5 to 10 percent of inorganic heating powder, 1 to 20 percent of cure cross-linking agent and 70 to 98.5 percent of diluents. A method for preparing the self-heating polyester fiber comprises the following steps: uniformly mixing the inorganic heating powder, the cure cross-linking agent and the diluents, thus obtaining the heating additive for polyester spinning; putting the master batches for polyester spinning in a melt spinning machine, and carrying out melt spinning, thus obtaining polyester strand; spraying the heating additive for polyester spinning on the surface of the polyester strand, and carrying out draft winding, drawing and sizing, thus obtaining the self-heating polyester fiber. The self-heating polyester fiber disclosed by the invention has remarkable heating effect and low cost, and the manufacturing technology is simple.

Description

technical field [0001] The invention relates to the field of functional textile functional materials, in particular to a self-heating polyester fiber and a preparation method thereof. Background technique [0002] Heating fiber is a new material that generates heat by itself and warms the body, and its water absorption is far stronger than other fibers. At present, the heating fibers on the market mainly include far-infrared heating fibers, hygroscopic heating fibers, and phase change fibers. All far-infrared heating fibers are obtained by blending and spinning far-infrared ceramic powder and masterbatch by means of internal addition. This will cause most of the far-infrared ceramic powder to be wrapped inside the fiber and cannot absorb infrared rays, resulting in The utilization rate of far-infrared ceramic powder is very low; fibers that can generate heat after moisture absorption, such as eks fiber, softwarm fiber, etc., also have great shortcomings. The body temperatur...
