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. ...

Embodiment Construction

[0027] Below, the structure and working principle of the present invention will be further described in conjunction with the accompanying drawings.

[0028] Such as figure 1 The illustrated biomimetic fibers include a first type of filament 16 and a second type of filament 17 . The second type of filament 17 is entangled on the surface of the first type of filament 16 to form a bionic fiber similar to velvet. The second type of filaments 17 and the first type of filaments 16 form network points 20 under the action of the network nozzles, making them entangled. Under different overfeeding conditions, the lengths of the filaments 16 and 17 between the two network points are different, thus forming a better three-dimensional structure. The first type of silk 16 is a bionic fiber main body, that is, the imitation velvet core structure, and the second type of silk 17 is attached to the surface of the first type of silk 16 by entanglement to form a velvet-like structure, and the m...
