Embodiment 1

[0055] Please refer to Figure 4 , The first embodiment of the present invention is:

[0056] According to the special-shaped nylon 6 fiber of this embodiment, the special-shaped nylon 6 fiber has a flat structure with a flat strip or tends to be a flat strip in cross section. The flat structure includes a first long side, a second long side, and a first long side. The circular arc and the second circular arc, the first long side, the first circular arc, the second long side and the second circular arc are respectively connected end to end in sequence to form the flat structure. Wherein, the first long side and the second long side are arranged in parallel, and the second long side is arranged directly below the first long side, and the convex arc surfaces of the first arc and the second arc face the outside respectively.

[0057] The structure of the special-shaped spinneret used to prepare the above-mentioned special-shaped nylon 6 fiber includes a substrate 1 and at least one sp...

Embodiment 2

[0058] Please refer to Figure 4 , The second embodiment of the present invention is:

[0059] A special-shaped nylon 6 fiber, except that "the flatness of the spinneret micropores is 12.0, and the number of the spinneret micropores is 12F" is different from the first embodiment, and the others are the same as the first embodiment.

Abstract

The invention relates to a special-shaped nylon 6 fiber. The special-shaped nylon 6 fiber is of a flat structure with the cross section which is in a flat strip shape or tends to be in the flat strip shape. The flat structure comprises a first long side, a second long side, a first arc and a second arc. The first long side, the first arc, the second long side and the second arc are sequentially connected end to end to form the flat structure. The invention further relates to a preparation method of the special-shaped nylon 6 fiber. According to the special-shaped nylon 6 fiber, the influences of increase of flatness on the production status and physical performance of the nylon 6 fiber can be reduced to be minimal, and the prepared special-shaped nylon 6 fiber is larger in flatness, has excellent moisture absorption and breathability, is pretty in gloss and better in dyeing performance, and has a good natural fiber imitating effect.

Description

Technical field [0001] The invention relates to chemical fiber technology, in particular to a profiled nylon 6 fiber and a preparation method thereof. Background technique [0002] Nylon is widely used in the field of apparel due to its excellent physical properties, such as high strength, good moisture absorption and bright coloring. In recent years, the research on nylon 6 fibers, especially the research on various differentiated nylon 6 fibers, has developed rapidly. [0003] The cross-section of traditional nylon is circular, and the surface of nylon 6 fiber with circular cross-section is weak in gloss, waxy, easy to bend, wrinkle, and pilling, which greatly restricts its development in the high-end weaving field. Profiled nylon 6 fiber is nylon with non-circular cross section. The research direction of special-shaped nylon 6 fiber is to increase the specific surface area of ​​nylon 6 fiber, that is, through the design of special-shaped cross-section, grooves are introduced i...
