Abstract

The invention discloses a bidirectional induction energy storage heat preservation polyester pre-oriented yarn and a preparation method thereof. In the melt spinning process of polyester dry chips, nano-zirconium carbide additives with a mass fraction of 10.0-30.0% are added online and polyester dry chips are uniformly blended and melted in the screw, and the blended melt is extruded from the micropores of the spinneret , cooled and solidified by side air blowing, the oil nozzles are oiled and clustered, and then input into the parallel guide wire winding system device, wound and formed, and high-efficiency bidirectional induction energy storage and heat preservation polyester pre-oriented yarns are produced. The fiber has higher efficiency two-way induction energy storage and heat preservation function, and it can be intertwined with other fibers to obtain super cotton-like wool-like composite fiber and its cold-proof and warm-keeping fabric products with different structural and functional characteristics, which has good sustainable development prospect.

Description

technical field [0001] The invention relates to a polyester pre-oriented yarn and a preparation method thereof, in particular to a nano-zirconium carbide capable of obtaining high-efficiency absorption of solar energy, natural energy and reflection of human body heat radiation heat source, bidirectional induction, energy storage, exothermic heat preservation and heat preservation. The polyester pre-oriented yarn and its preparation method belong to the technical field of new functional fiber materials. Background technique [0002] At present, the thermal insulation fiber materials used in the field of clothing textiles mainly rely on the thickness and density of the textile fabric and the increase of the still air layer between the fibers, thereby reducing the heat conduction and heat convection of the clothing and achieving the purpose of traditional warmth. There are recently developed hollow fibers and microfibers, phase-change heat preservation materials and far-infrare...
