Abstract:
The present invention provides a thermal insulation flocculus material, including a first outer layer and a base layer, the first outer layer being placed on a first surface of the base layer, wherein the first outer layer comprises a multi-layered single web, and the multi- layered single web comprises 15-30% of a synthetic fiber material with 0.2-2 Denier fineness; a water repellent treatment is previously performed on the synthetic fiber material with 0.2-2 Denier fineness; and the water repellent treatment is not performed on the rest of the components, the rest of the components comprising 45-75% of a synthetic fiber material with 0.2-4 Denier fineness and 10-25% of a low melting point fiber material with 1.5-5 Denier fineness; and the base layer is substantially composed of a fiber raw material on which the water repellent treatment is not performed. The thermal insulation flocculus material provided by the present invention possesses good water repellency, and has minimal effect on the overall thickness and compression resilience of the flocculus material. The method allows for effective control of material costs, and averts an increase in difficulty in the operational process.
