Problems solved by technology

However, since the gas stored in the hollow cylinder is not sealed, it is easy to escape from the bottom of the fiber cylinder, especially when it is squeezed, a large amount of gas escapes from the hollow fiber, which greatly reduces the insulation performance of the hollow fiber

Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] Such as figure 2 As shown, the airbag fiber of the present invention includes a fiber body 10, a hollow portion 11 is arranged in the middle of the fiber body 10, and a plurality of separation layers 20 are arranged at intervals in the hollow portion 11, and the separation layer 20 separates the hollow portion 11 to form a plurality of volumes capable of Freely variable air bag 21. The airbags 21 are arranged in the hollow portion 11 in an irregular manner. Thus, by arranging the airbags 21 in the hollow portion 11 in a bionic manner, it is possible to prevent gas from escaping, improve the air retention capacity inside the fiber, and then improve the heat retention capacity of the fiber.

[0016] The fiber body 10 and the separation layer 20 are solidified from polymer melt.

[0017] The above-mentioned polymer melt can be polyester,...

Abstract

The invention provides an air bag type fiber and a preparation method thereof. The air bag type fiber comprises a fiber body; the hollow part is arranged in the middle of the fiber body; the plurality of separation layers are arranged in the hollow part at intervals; the plurality of air bags are formed in the hollow part through separation of separation layers; the volumes of the multiple air bags can be freely changed, and the multiple air bags are arranged in the hollow part in an irregular mode. According to the air bag type fiber, the air bags which are irregularly arranged are adopted, air escape is prevented, the air retaining capacity is improved, the hollow rate of the air bag type fiber is increased, the air bag type fiber has good bulkiness and rebound resilience, and therefore the heat preservation performance of the fiber is improved.

Description

technical field [0001] The invention relates to a fiber, in particular to an airbag fiber and a preparation method thereof. Background technique [0002] With the improvement of the quality of life, the performance requirements of people's functional fibers are getting higher and higher, such as comfort, perspiration, warmth, breathability and so on. However, the performance of these functional fibers on the market is far from meeting people's requirements. [0003] Hollow fibers are widely used in thermal fabrics due to their special structure. Such as figure 1 As shown, there is a hollow part in the middle of the fiber body, so the fiber is in the shape of a hollow cylinder, the outer layer is a cylindrical shell formed by solidification of polyester fiber melt, and the inner layer is a hollow cylinder composed of gas. Since the inner layer of gas has better heat insulation than the outer layer of fibers, the hollow fibers have better thermal performance. However, sinc...
