Abstract

The invention relates to a nano zirconium carbide induction heat-storage heat-preservation polyester fiber and a preparation method thereof. The preparation method comprises the steps of: adding 1.0-8.0% of nano zirconium carbide using as an additive in an online manner to evenly blend and fuse together with a polyester chip in a screw rod, extruding blend melt from a spinneret micro-hole, winding the extruded blend melt at the winding speed of 3000-3200m/min to prepare a POY (polyester pre-oriented yarn) silk tube by using the processes of cooling, curing, oiling and bundling by a nozzle, stretching to deform after balancing, so as to prepare the nano zirconium carbide induction heat-storage heat-preservation polyester fiber. The nano zirconium carbide induction heat-storage heat-preservation polyester fiber has the functions of efficiently and selectively absorbing visible light and a near infrared ray in a solar radiation ray, and reflecting the heat radiation of a human body, so as to have the functions of two-way temperature induction adjustment and heat preservation, changes the heat-storage mode of cold protective clothing, and has the characteristics of being high in additional value, good in quality and significant in cost performance.

Description

technical field [0001] The invention relates to a preparation method of nano zirconium carbide induction heat storage and heat preservation polyester fiber, which belongs to the technical field of functional fiber materials. Specifically, it is a technology for preparing and obtaining nano-zirconium carbide induction heat storage and thermal insulation polyester fiber by adding nano-zirconium carbide online to polyester chips for blending, melt spinning, stretching and deformation processing. Background technique [0002] At present, fibers and products with heat storage and thermal insulation effects on the domestic and foreign markets are mainly prepared through the following technical approaches, such as: microcapsule coating method to prepare thermal insulation fibers and their products, but with this process technology and equipment This product has poor air permeability, rough hand feeling, uneven dispersion of phase change materials, easy continuous seepage and loss, ...
