Polyamide fiber

Abstract

The invention belongs to the technical field of polyamide fibers and specifically relates to a polyamide fiber. A preparation process of the polyamide fiber comprises the following steps of S1, sufficiently drying montmorillonite in a drying box first; and then putting the montmorillonite into distilled water to be scattered and dispersed by using ultrasonic waves to obtain a suspension liquid; and then adding butadiene styrene rubber emulsion to the suspension liquid; carrying out mixed intercalation on an obtained mixture during strong stirring; and carrying out demulsification flocculationand coprecipitation by using electrolyte to obtain complex liquid in which the montmorillonite is uniformly dispersed in the butadiene styrene rubber emulsion. According to the polyamide fiber, by adding a spinning solution in a solution storage tank to vibration ponds in batches, bubbles in the spinning solution can be eliminated in a vibrating manner through up-and-down vibrating of the vibration ponds; as multiple groups of vibrating ponds are arranged, the spinning solution in the same batch is vibrated for multiple times by using the multiple vibration ponds so that the bubble eliminatingefficiency can be greatly enhanced; and as inserting and tamping rods are arranged at the tops of the vibration ponds, the spinning solution can collide with the inserting and tamping rods in a contacting manner in the upwardly moving process of the vibration ponds so that the bubbles in the spinning solution can be broken up.

Description

technical field [0001] The invention belongs to the technical field of polyamide fibers, in particular to a polyamide fiber. Background technique [0002] Polyamide fiber, commonly known as nylon, the most prominent advantage of polyamide fiber is that it is superior to other fibers in abrasion resistance, followed by its good elasticity, its elastic recovery rate is comparable to that of wool, and its light weight, with a specific gravity of 1.14. Among commercialized synthetic fibers, it is second only to polypropylene (polypropylene, specific gravity less than 1), and lighter than polyester fiber (specific gravity 1.38), so polyamide fibers can be processed into fine, soft and smooth silk for weaving Beautiful and durable fabric, in addition, it has the same corrosion resistance as polyester fiber, not afraid of moths, not afraid of mildew. [0003] The disadvantage of polyamide fiber is that its light resistance is slightly poor. If it is exposed to sunlight for a long ...

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, solve the poor wear resistance of polyamide fibers in the prior art, and the need to carry out defoaming treatment on the configured spinning stock solution during the production of polyamide fibers, in the prior art The way of adding defoamer or vacuuming is mostly used for defoaming, but for the problem that the effect of these two defoaming methods is not good for the spinning stock solution with large consistency, a kind of polyamide fiber proposed by the present invention
