Problems solved by technology

Wearing chemical fiber underwear next to the skin will produce itchy skin and reduce wearing comfort
Wearing chemical fiber clothes, due to frictional electrification, the static voltage generated is very high. When touching conductive objects such as metal objects or shaking hands with people, it will discharge, causing electric shock and discomfort. Moreover, the cloth is flammable and easy to damage. human body injury

Abstract

The invention discloses a manufacture method of conductive fire-retardant acrylic fiber. The manufacture method comprises the following steps: (1) preparing a spinning solution; (2) performing spinning formation; (3) performing copper salt treatment; (4) adding acrylic fiber containing copper ions obtained in the step (3) into a mixed aqueous solution, and reacting in an airtight high-temperature reaction kettle at 120-140 DEG C for 4-5 hours to prepare the fire-retardant acrylic fiber; (5) taking out and cleaning the acrylic fiber obtained in the step (4), and putting the acrylic fiber at 70-90 DEG C for 2-3 hours in a constant-temperature manner. Through the manner and with the adoption of the manufacture method of conductive fire-retardant acrylic fiber, the acrylic fiber subjected to the antistatic treatment can prevent static electricity during application, ensures normal application of a user, has a fire-retardant function, and overcomes the flammable defect of cloth.

Description

technical field [0001] The invention relates to the field of fibers, in particular to a method for making a conductive flame-resistant acrylic fiber. Background technique [0002] The static electricity generated by clothing made of different materials will make the clothes entangled with each other, making it inconvenient to wear. When the charge of the clothing material and the skin are different, they will be attracted to each other and the phenomenon of "skirt hugging the legs" will appear, making it difficult for people to walk. Due to severe static electricity, chemical fiber clothes are particularly easy to absorb dust particles with different charges in the air, which can easily stain the clothes; chemical fiber clothes are also particularly easy to absorb dandruff. Wearing chemical fiber underwear next to the body will cause itching on the skin and reduce the wearing comfort. Wearing chemical fiber clothes, due to frictional electrification, the static voltage gen...
