Problems solved by technology

For example, the special-shaped nylon 6 fiber with a "ten" cross-section has poor gloss, and the special-shaped nylon 6 fiber with a triangular cross-section has relatively poor water absorption and moisture permeability, which limits its application.

preparation example Construction

[0027] A method for preparing special-shaped nylon 6 fibers, which comprises melting polyamide 6 dry slices with a relative viscosity of 2.40-2.70 to obtain a polyamide 6 melt, the melting temperature being 250-270°C; melting the polyamide 6 The body is extruded through the spinneret microholes 2 on the above-mentioned spinneret to obtain polyamide 6 fiber tow, and the polyamide 6 fiber tow is sequentially subjected to monomer suction, side blowing cooling, cluster oiling, drawing Stretching and network interlacing, and then winding to obtain the special-shaped nylon 6 fiber.

[0028] As can be seen from the foregoing description, the beneficial effects of the present invention are:

[0029] (1) By the above-mentioned special-shaped cross-section design of the spinneret microhole of the spinneret, the cross-section presents a double-edged zigzag as a whole, so that the cross-section of the special-shaped nylon 6 fiber prepared by the spinneret of the present invention is a dou...

Embodiment 1

[0052] Please refer to Figure 1-3 , Embodiment 1 of the present invention is:

[0053] A spinneret, comprising a substrate 1 and seven spinneret holes 2, the spinneret holes 2 are arranged on the substrate 1, the cross section of the spinneret holes 2 is a sawtooth structure, and the sawtooth The structure includes two sawtooth parts, the sawtooth part includes four semicircle arcs 21 with the same radius, the four semicircle arcs 21 are arranged in sequence, and a straight line 22 passes between two adjacent semicircle arcs 21 The two serrated parts are connected to each other to form a symmetrical closed structure, and the four semicircular arcs 21 on one serrated part correspond to the four semicircular arcs 21 on the other serrated part. The distance between the centers of two adjacent semicircular arcs 21 in the serrated portion is 4 times the radius, and the distance between the centers of two semicircular arcs 21 correspondingly arranged in the two serrated portions i...

Embodiment 2

[0057] Please refer to Figure 1-3 , the second embodiment of the present invention is:

[0058] A spinneret, only "the number of spinneret microholes 2 is 12, and the distance between the centers of two adjacent semicircular arcs 21 in the serrations is 4.2 times the radius, The distance between the centers of the two semicircular arcs 21 that are set correspondingly is 1.2 times the radius" is different from the first embodiment, and the others are the same as the first embodiment.

[0059] A special-shaped nylon 6 fiber is obtained by extruding polyamide 6 slices through the spinneret micro-holes 2 on the above spinneret to obtain the special-shaped nylon 6 fiber.

[0060] A method for preparing special-shaped polyamide 6 fibers. The polyamide 6 dry chips with a relative viscosity of 2.70 are sent to a screw extruder through a pipeline for melting, mixing, compression and extrusion to obtain a polyamide 6 melt. The melting, kneading, compression and extrusion temperatures...

Abstract

The invention relates to a spinneret plate which comprises a base plate and at least one spinneret micro-hole. The spinneret micro-hole is formed in the base plate, a cross section of the spinneret micro-hole is of a sawtooth structure, the sawtooth structure comprises two sawtooth portions, each sawtooth portion comprises four semi-circular arcs identical in radius, the four semi-circular arcs are sequentially arranged, the adjacent two semi-circular arcs are connected linearly, the two sawtooth portions are mutually connected to form a symmetrical closed structure, and the four semi-circular arcs at one sawtooth portion correspond to the four semi-circular arcs at the other sawtooth portion in a one-to-one mode. The invention further relates to a profiled nylon 6 fiber and a making method thereof. The profiled nylon 6 fiber has good luster and moisture absorption and sweat releasing functions, and a fabric made from the fiber has the soft and exquisite hand feeling of cashmere and also has good dyeing properties, rapid moisture absorption and guidance properties and other excellent characteristics.

Description

technical field [0001] The invention relates to chemical fiber technology, in particular to a spinneret, special-shaped nylon 6 fibers prepared from the spinneret, and a preparation method of the above-mentioned special-shaped nylon 6 fibers. Background technique [0002] Nylon is widely used in the garment industry due to its excellent physical properties, such as high strength, good hygroscopicity and bright dyeing. In recent years, the research on nylon 6 fiber, especially the research on nylon 6 fiber with various additional functions, has developed rapidly. [0003] The cross-section of traditional nylon is circular, and the hygroscopicity of nylon 6 fiber with circular cross-section is relatively poor, and it is easy to bend and wrinkle, which greatly limits its development in the field of high-end weaving. The special-shaped nylon 6 fiber is nylon with a non-circular section. The research direction of special-shaped nylon 6 fiber is to increase the specific surface ...
