Bionic fiber and bionic fiber manufacturing device

Abstract

The invention discloses a bionic fiber and a manufacturing device of the bionic fiber, the bionic fiber comprises a bionic structure formed by sequentially entangling a plurality of silk threads, the entangled fiber is a three-dimensional fiber structure formed around a main fiber in any direction in the radial direction, the plurality of silk threads comprise a first type of silk and a second type of silk, closed or semi-closed cavities are formed in the first type of silk and the second type of silk, the first type of silk and the second type of silk are entangled to generate first network points, the first type of silk is a bionic fiber main body, namely a velvet core-imitating structure, and the second type of silk is attached to the surface of the first type of silk in an entangled manner to form a velvet silk-imitating structure. Monofilaments of the second type of filaments form a secondary velvet filament imitating structure. By adopting the bionic fiber disclosed by the invention, extremely high heat retention property and service life can be ensured, and excellent bulkiness can also be ensured.

Description

technical field [0001] The invention relates to a bionic fiber and a device for manufacturing the bionic fiber. Background technique [0002] Hollow fiber refers to a chemical fiber with a tubular cavity running through the axial direction of the fiber. It can be used for winter clothes, quilts and padding wadding. Good thermal effect. At the same time, the existence of the hollow also greatly reduces the weight of the fiber. [0003] Goose down, as a natural fiber with strong thermal insulation effect, is widely used as the internal filler of thermal insulation products. Goose down fiber exists in the form of velvet. The velvet is composed of velvet core and velvet filaments. . It is precisely because of its unique structure, the multi-level velvet and the cavity structure of the velvet that it can accommodate more air, thus giving it higher warmth retention and bulkiness. However, as a natural fiber, goose down has a long production cycle and a relatively high price. ...

Problems solved by technology

However, as a natural fiber, goose down has a long production cycle and a relatively high price

[0004] At present, the relevant hollow fiber products on the market, due to the defects in the production process, affect the hollowness of the fiber to a certain extent, so that the product cannot achieve the expected warmth retention, the hollowness cannot be effectively preserved for a long time, and the use of the product is also greatly shortened. cycle

The yarn has a certain degree of elasticity, warmth retention and other properties, but the hollow fiber is not treated, its warmth retention cannot be optimized and the service life of the product is greatly shortened
