Abstract

The invention provides a preparation method of wear-resisting and antistatic high-performance enhanced nylon yarns. The preparation method comprises the following steps: (1) preparing raw materials in parts by weight: 55-65 parts of PA6 slices, 20-30 parts of carbon fibers, 5-10 parts of silicone powder, 3-5 parts of an internal mixing type antistatic agent and 1-3 parts of an auxiliary agent, wherein the auxiliary agent comprises a coupling agent, an anti-oxidization auxiliary agent and a lubricating agent in a weight ratio of 1 to 1 to 1; adding the raw materials into a high-speed mixing machine, and mixing uniformly; (2) drying the raw materials; (3) preparing spinning fluid, namely accurately adding all the raw materials by using a master batch injection and dilution pump, mixing and melting; (4) spinning, namely quantitatively pressing the spinning fluid into a spinning component by a metering pump and spraying the spinning fluid out by a spinning plate to form a yarn bundle in a spinning window; and (5) carrying out post-machining, namely sequentially carrying out procedures of stretching and twisting, shaping, balancing, dyeing and grading, checking and packaging on the prepared fibers; and finally, preparing the wear-resisting and antistatic high-performance enhanced nylon yarns. The product prepared by the preparation method has high strength, high wear resistance and high antistatic performance.

Description

technical field [0001] The invention relates to a preparation method of wear-resistant and antistatic high-performance reinforced nylon yarn, which belongs to the technical field of chemical fibers. Background technique [0002] Nylon is the trade name of polyamide fiber. Polyamide fiber is commonly known as nylon (Nylon), the English name is Polyamide (referred to as PA), and the density is 1.15g / cm3. It is a thermoplastic resin containing repeated amide groups—[NHCO]—on the main molecular chain. The general term includes aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its naming depends on the specific number of carbon atoms in the synthetic monomer. [0003] Polyamide is mainly used for synthetic fibers. Its most prominent advantage is that its wear resistance is higher than that of all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fib...
