Abstract

The invention discloses special-shaped nylon 6 filaments and a preparation method thereof, and relates to chemical fiber technology. The preparation method prepares special-shaped nylon 6 filaments and spinnerets by improving the structure of the spinneret and cooperating with the method of coloring nylon 6 filaments with stock solution. It includes a substrate and at least one spinneret microhole, the spinneret microhole is arranged on the substrate, the cross section of the spinneret microhole is trilobal, the angle between two adjacent blades is 120°, the shape of each blade, The dimensions are all the same; the blades are in a "ten" structure, and the ends of the "ten" structure are arc-shaped. The special-shaped nylon 6 filament and its preparation method provided by the present invention, by changing the shape of the spinneret and optimizing the spinning process of the dope-colored nylon 6 filament, to increase the specific surface area of ​​the fiber and the cohesion between the monofilaments to lock the dope The pigment or dye powder in the colored nylon 6 filament enables the fiber to show a full color and luster, and has high washing fastness, and has the function of moisture absorption and perspiration.

Description

technical field [0001] The invention relates to chemical fiber technology, in particular to a special-shaped nylon 6 filament and a preparation method thereof. Background technique [0002] Nylon is widely used in the garment industry due to its excellent physical properties. In recent years, the research on nylon 6 filaments, especially the research on differentiated nylon 6 filaments that can meet people's needs, has developed rapidly. [0003] The cross-section of conventional nylon 6 filament is circular, and the special-shaped nylon 6 filament is nylon with non-circular cross-section. The research direction of special-shaped nylon 6 filaments is to increase the specific surface area of ​​nylon 6 filaments, that is, through the design of special-shaped cross-sections, grooves are introduced into the outer contour of the surface of nylon 6 filaments to enhance the capillary effect. The design of different cross-sectional shapes can make nylon 6 6. The luster, feel, hygr...
