Abstract

The invention discloses an induction-type heat-accumulating and heat-preserving nanometer zirconium carbide-polyester draw textured yarn and a preparation method thereof. The induction-type heat-accumulating and heat-preserving nanometer zirconium carbide-polyester draw textured yarn is prepared by adding 10.0-20.0% of a nanometer zirconium carbide additive by mass and dry polyester slices, and performing uniformly-blending and melting and ultrahigh speed hot-tube spinning POY-DTY technical route in a screw rod. The nanometer zirconium carbide-polyester draw textured yarn can efficiently and selectively absorb visible rays and near infrared rays in solar rays, can reflect thermal radiation energy of a human body, has bidirectional induction-type heat-accumulating and heat-preserving effects, is mainly applied to the field of novel silk-like, cotton-like and wool-like heat-accumulating, heat-preserving, cold-proof and warming textiles and the like, and has a wide development prospect.

Description

technical field [0001] The invention relates to a polyester false-twist textured yarn and a preparation method thereof, in particular to a nano-zirconium carbide polymer that can obtain the functional characteristics of automatic induction heat storage and heat preservation with high-efficiency selective absorption of visible light, reflection of infrared rays, and reflection of human body heat radiation heat source. The ester false twist textured yarn and its preparation method belong to the technical field of novel functionally differentiated fiber materials. Background technique [0002] Traditional thermal insulation materials mainly rely on the thickness and density of the fabric and increase the static air layer between the fibers to reduce the heat conduction and heat convection of the clothing, so as to achieve the purpose of traditional thermal insulation, but the overall thickness of the clothing will be bloated. It is convenient for movement and lacks aesthetic fe...
