Abstract

The invention discloses a rapid high-rebound high-heat-preservation floccus flake and a preparation method thereof. The elastic heat-preservation floccus flake is prepared by processing raw materials of superfine polyster fiber, hollow fiber with triangular or special-shape holes therein, composite elastic fiber, viscose fiber, polyster fiber with common properties and hollow fiber with a round inner part. The floccus flake is prepared by blending novel high-performance fiber, special fiber, functional fiber and the conventional fiber in different ratios. The obtained floccus flake has the characteristics of quick and high rebound resilience and high heat preservation. The floccus flake meets requirements on lightness of a sleeping bag, compression and rebound, heat preservation, comfortability and the like. The product overcomes the defects of the heat-preserving floccus flake in the conventional sleeping bag, and increases heat preservation ratio and compression resilience ratio.

Description

technical field [0001] The invention relates to a fast, high-resilience, high-warmth floc and a preparation method thereof. Background technique [0002] At present, the thermal insulation wadding used in sleeping bags at home and abroad mainly includes spray-bonded cotton (including elastic wadding), hot-melt cotton, imitation silk cotton, and melt-blown cotton, with different properties and characteristics. [0003] Sprayed cotton is the most commonly used ordinary wadding. Its advantages are fluffy, good rebound, and thickness. The disadvantages are that it feels rough, not washable, and has a low warmth retention rate. Elastic wadding only adds a small amount of bonding fiber in the production process of glued cotton, and the warmth retention and rebound effect are basically the same as that of glued cotton. [0004] Hot-melt cotton, also known as glue-free cotton, uses bonding fibers as the bonding process, and the surface is not sprayed with adhesives. Its characteris...
