Problems solved by technology

[0005] Most of the thermal insulation filling materials are loose materials including fine fibers (such as spherical fiber aggregates). Since the fibers in them have no fixed connection relationship, they are prone to agglomeration and entanglement during the washing process, resulting in a decrease in the performance of the thermal insulation filling material. ; Therefore, the washing resistance of the insulation filling material is not good
[0006] The traditional thermal insulation flake material is a multi-layer netted sheet. Because it has a relatively fixed netted structure, it has good washing resistance, but its bulkiness, compression resilience, thermal insulation (thermogravimetric efficiency), etc. Generally worse than insulation fill materials

Description

technical field [0001] The invention belongs to the technical field of thermal insulation wadding materials, and in particular relates to a thermal insulation wadding material [0002] Materials and their preparation methods, insulation products. Background technique [0003] In clothing, quilts, etc., thermal insulation materials are often filled to improve the thermal insulation (thermogravimetric efficiency) of the product. Traditional insulation materials are mainly natural down such as duck down and goose down. The physical structure of natural down determines its good bulkiness, compression resilience, heat retention and other properties. However, the source of natural down is unstable, so its cost is high, its output is limited, and its quality is uneven, and natural down is generally poor in durability, prone to mildew, prone to allergic reactions, and poor in heat preservation in humid environments, which lead to its application. The scope is limited. [0004] F...
