Problems solved by technology

However, when the proportion of chemical fibers is low, the bulkiness and compression resilience also decrease accordingly
Especially when the natural kapok fiber reaches 90%, it is difficult to achieve the bulkiness and compression resilience of the floc.

Abstract

The invention relates to kapok wadding sheets and a production method thereof. The components selected fiber raw materials of the kapok wadding sheets and the weight percentage thereof are that 40 to 68 percent of kapok fiber, 8 to 12 percent of cellulose fiber, 13 to 32 percent of polyester porous fiber and 7 to 20 percent of polyester 3-D crimped fiber. The processing steps of the raw materials are opening picking, opening and cotton blending, feeding hopper vibrating, combing, laying, pulling and extending of the disordered, powdering, thermal melting, ironing and cooling and so on. Indexes of the kapok wading sheets of the invention, such as bulkiness, compression elasticity, heat retaining property, etc., are better than standards of the industry, and the invention provides the textile market with wadding sheets that are light, heat-retaining efficient and more environment friendly.

Description

technical field [0001] The invention relates to a wadding used in textile industry production, in particular to a kapok wadding and a production method thereof. Background technique [0002] Kapok fiber is the wild fruit fiber of woody plants, because its fiber hollowness is as high as more than 80%. The cell wall is thin, the length is short, the strength is low, and the specific gravity is very light. The kapok fiber has poor elasticity after being flakes, and the fiber is powdery after a long time of use. [0003] CN 1644779A discloses a manufacturing method of kapok batting. The invention adopts 25-90% natural kapok fibers, 5-40% low-melting-point fibers, and 0-70% chemical fibers with good compression resilience. After the fiber raw materials are mixed and loosened, they are processed into a web to form a fiber web; The web after web treatment is bonded to make kapok batting. The bulkiness of the kapok batting is controlled by the ratio of 0-70% chemical fibers with...
