Fiber

Abstract

The invention discloses a fiber. The fiber consists of at least two monofilaments, wherein the section of each monofilament comprises 3 to 5 triangular sections; the bottom corners of the triangular sections are positioned on the same straight line; every two adjacent triangular sections of the section of each monofilament are connected with each other to form sawtooth-shaped monofilament. The specially-shaped fiber has the advantages of a triangular fiber and the advantages of a crossed fiber, so that the specially-shaped degree of the produced specially-shaped fiber is high; and a fabric has various performance advantages of saturated color, brightness, high bulkiness, high hygroscopicity, high elasticity, good handfeel and the like.

Description

technical field [0001] The invention relates to a fiber, especially a fiber with a zigzag cross section. [0002] Background technique [0003] Synthetic fibers are usually round fibers with a solid structure inside, so their hygroscopicity and dyeability are poor, and when light hits the surface, it is easy to form diffuse reflection and poor gloss. Therefore, the comfort of the fabric is often not good, and it is difficult to satisfy the needs of modern people. [0004] Shaped fiber is the fiber obtained after the cross-section is shaped. This fiber can endow the fabric with a variety of performance advantages, so it is widely used. The production and processing process of common special-shaped fibers in synthetic fibers is to open a number of spinneret holes with cross-sections corresponding to the cross-sections of fibers on the spinneret, and spray the spinning melt from the special-shaped spinneret holes on the spinneret. After cooling and solidification, primary fi...

Problems solved by technology

[0005] At present, there are many cross-sections of special-shaped fibers that have been industrialized, such as triangular, trilobal, pentagonal, cross-shaped, flat, C-shaped, H-shaped and cross-shaped fibers, etc., but most of the special-shaped fibers currently produced have only a single and the same Therefore, it is difficult to perform multiple functions at the same time. For example, although triangular, trilobal, and pentagonal fibers have the function of small prisms, they can split the natural light and recombine them, giving off a silky luster and giving people a special feeling. However, their moisture absorption The moisture conduction performance is very poor; although the flat fiber has a good gloss effect, its moisture absorption and moisture conduction performance is very poor; and the C-shaped, H-shaped, and cross-shaped fibers, the capillary phenomenon produced by the groove structure on the surface It can have good moisture absorption and perspiration effect, but its gloss is relatively poor. Therefore, people hope to have a fiber with full color, bright luster, good fluffiness, good moisture absorption, good moisture perspiration and perspiration, good elasticity and hand feeling. Good and other performance advantages
