Description

Technical Field

[0001] The utility model discloses a double-component fiber, belonging to the technical field of fibers. Background Art

[0002] Fiber is a substance composed of continuous or discontinuous filaments. In animals and plants, fiber plays an important role in maintaining tissues. Fiber has a wide range of uses. It can be woven into fine threads, threads and hemp ropes, and can also be woven into fiber layers when making paper or felt. It is also often used to make other materials and to form composite materials with other materials.

[0003] Existing fibers are divided into natural fibers and synthetic fibers, and synthetic fibers are currently the mainstream research direction, because synthetic fibers have more superior and controllable properties than natural fibers, and can often achieve multiple directional effects on one product, which is difficult for natural fibers to achieve. For example, PLA fibers have a variety of practical properties, but they also produce multi-angle defects. However, since PLA fibers are single-component fibers, these defects can only be changed by improving the material process. However, it is difficult to change the material process of PLA fibers, the experimental cost is high, and the improvement of the results cannot be guaranteed. Therefore, in order to solve this problem, the utility model proposes a new solution. Utility Model Content

[0004] The purpose of the utility model is to provide a bicomponent fiber in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a two-component fiber, including a fiber body, wherein the fiber body includes a first fiber component and a second fiber component, the first fiber component is set to at least one of a PLA component and a PBSA component, the second fiber component is set to at least one of a PLA component and a PBSA component, and the fiber body is set to one of a skin-core structure and a parallel structure.

[0006] Preferably, the first fiber component and the second fiber component are configured as fiber filaments of different components.

[0007] Preferably, the fiber body is configured as a skin-core structure, the first fiber component is configured as a skin structure, and the second fiber component is configured as a core structure.

[0008] Preferably, the first fiber component is configured as a PBSA component, and the second fiber component is configured as a PLA component.

[0009] Preferably, the first fiber component is configured as a PLA component, and the second fiber component is configured as a PBSA component.

[0010] Preferably, the fiber body is arranged as a parallel structure, the first fiber component is arranged as a PLA component, and the second fiber component is arranged as a PBSA component.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By configuring the fiber to be composed of a first fiber component and a second fiber component with different components, both fiber filaments can use a PBSA component or a PLA component, and the fiber structure can use a skin-core structure or a parallel structure. The PBSA component and the PLA component are combined to form a new two-component fiber, so that the advantages of both can work at the same time, and at the same time, some of the shortcomings of the two can be compensated by each other, so that the new fiber has stronger performance, thereby avoiding the difficulty and cost of improving performance by only changing the single-component material process.
