Abstract: A method for producing a fluffy temperature regulating warmth retention material and the fluffy temperature regulating warmth retention material produced therefrom are disclosed. The method comprises: selecting a low melting point fiber and an additional fiber; carding to form a single web; spray coating a phase change material along at least part of the length of a surface of the single web; lapping layer by layer of the single web; and performing a heat setting reinforcement to form the warmth retention material. According to the present invention, a fluffy temperature regulating warmth retention material comprising an appropriate ratio of a phase change material may be obtained and the material exhibits a satisfactory temperature regulating effect, and meanwhile, it can maintain, to the full extent, or is close to, the original filling power and soft hand feeling where no phase change material is incorporated. In addition, the phase change material can be retained very well within the fluffy temperature regulating warmth retention material and thus has a wash resistance property.

Abstract: The present invention provides a thermal insulation filling material and preparation method thereof and a thermal insulation product, and pertains to the field of thermal insulation filling materials. The thermal insulation filling material of the present invention includes: a bulk fibre; and a spherical fibre assembly, where a water-repellent layer is formed on a surface of the bulk fibre and of the spherical fibre assembly, and a weight ratio of the bulk fibre to the spherical fibre assembly is between about 30:70 and about 70:30. The thermal insulation filling material is good in wash durability, and has comprehensive performance such as better blowable processability, quick-drying property, compression-resilience property, and thermal insulation property, etc. The method for preparing the thermal insulation filling material includes: adding a water-repellent agent in the process of gas-flow mixing the bulk fibre and the spherical fibre assembly, and then heating to form a water-repellent layer on the surface of the bulk fibre and of the spherical fibre assembly.
