Abstract

The invention provides a method for preparing an energy-storing and temperature-adjusting fiber with a far-infrared function. The method is characterized by comprising the following steps: 1, placing porous nanometer powder, triallyl isocyanurate, polyethylene glycol diacrylate, polyethylene glycol, nanometer magnesium-aluminum composite oxide and an initiating agent into water as a solvent, adopting an ultrasonic dispersing method under reduced pressure, reacting at 65-75 DEG C for 2-5 h, and finally obtaining a far-infrared energy-storing phase change material through centrifugal dehydration; 2, conducting drying treatment on the far-infrared energy-storing phase change material, conducting compounding granulation on the dried far-infrared energy-storing phase change material and polymer slices through double screws, and then obtaining the energy-storing and temperature-adjusting fiber with the far-infrared function through melt spinning, wherein the spinning temperature is 260-315 DEG C and the spinning speed is 800-3500 m / min. The prepared far-infrared phase-changing and energy-storing material has the advantages that the energy-storing and temperature-adjusting capabilities are high, the preparation cost is low, the heat-resisting stability is high, and the operation is simple.

Description

technical field [0001] The invention belongs to the field of preparation of far-infrared intelligent temperature-regulating fibers, in particular to a method for preparing energy-storage and temperature-regulating fibers with far-infrared functions. Background technique [0002] Phase-change energy storage and temperature-regulating fiber is a high-tech fiber that has developed rapidly in recent years. It can achieve the purpose of energy storage and temperature control by adjusting the ambient temperature of the microspace outside the body. Due to the poor heat resistance of microcapsule phase change materials and the easy leakage of blended phase change materials, the development of energy storage and temperature control functions of polyester fibers and polyamide fibers is greatly restricted. Far-infrared fiber is a functional fiber containing far-infrared powder. By absorbing far-infrared rays, the superficial skin of the human body can undergo special physiological cha...
