Embodiment 1

[0018] Example 1: Weigh 100g of polyamide hot-melt adhesive with a melting point of 105°C, stir and heat to 120°C, wait until it completely melts and flows, add 0.01g of fluorocarbon polyoxyethylene ether, 0.01g of pentaerythritol ester, stir evenly, Then weigh 0.1g of ultra-fine copper powder with a particle size of about 150nm, slowly add it to the hot melt adhesive while stirring, and transfer it to the dropper between the hot rollers after the color is evenly dispersed. When heat-setting the PP fiber, open the dropper and process the PP. After air-drying, the finished fiber is collected by a drum, and the fiber is woven into a cloth sample, and its specific resistance is tested after washing 50 times.

Embodiment 2

[0019] Example 2: Weigh 100g of polyamide hot-melt adhesive with a melting point of 115°C, stir and heat it to 130°C, wait until it completely melts and flows, add 0.05g of fluorocarbon polyoxyethylene ether, 0.05g of pentaerythritol ester, stir evenly, Then weigh 1.0g of ultra-fine copper powder with a particle size of about 550nm, and slowly add it to the hot melt adhesive while stirring. After the color is evenly dispersed, transfer it to the dropper between the hot rollers. When heat-setting polypropylene fibers, open the dropper and process PP. After air-drying, the finished fiber is collected by a drum, and the fiber is woven into a cloth sample, and its specific resistance is tested after washing 50 times.

Embodiment 3

[0020] Example 3: Weigh 100g of polyamide hot-melt adhesive with a melting point of 145°C, stir and heat it to 180°C, wait until it completely melts and flows, add 0.1g of fluorocarbon polyoxyethylene ether, 0.1g of 2,6-tertiary butyl Base-4-methylphenol, stir evenly, then weigh 5g of ultra-fine copper powder with a particle size of about 1000nm, slowly add it to the hot melt adhesive while stirring, and after the color is evenly dispersed, transfer it to the drop between the hot rollers in the liquid container. When heat-treating polyester fibers, open the dropper and treat PP. After air-drying, the finished fiber is collected by a drum, and the fiber is woven into a cloth sample, and its specific resistance is tested after washing 50 times.

Abstract

The invention relates to a preparation method of an anti-static fiber, and particularly the preparation method has the advantages that the cost is cost, and the fiber is good in electric conductivity, strong in electric conduction durability, lubricating in hand feeling and excellent in dyeing property. The preparation method specifically comprises the following steps: gradually adding ultra-fine copper powder into liquid-state polyamide hot melt adhesive under high-speed stirring condition according to the proportion that the weight ratio is 0.1% by weight-10% by weight, simultaneously adding 0.01% by weight-0.1% by weight of lubricating agent and 0.01% by weight-0.1% by weight of antioxidant, fully mixing, then coating on the surface of the fiber during the heat setting process of the fiber, cooling and then curing so as to obtain the fiber with the good anti-static property.

Description

Technical field [0001] The invention relates to a preparation method of an antistatic fiber, in particular to a preparation method of an antistatic fiber with low cost, good fiber antistatic performance, strong conductive durability, lubricating hand feeling and good dyeability. Background technique [0002] Due to its hydrophobicity, synthetic fibers tend to accumulate static charges due to friction when dry, and their voltage can reach more than 10kV. Therefore, clothes made of synthetic fibers often give people an unpleasant feeling, such as entanglement in skirts during walking, electric sparks when undressing, and problems such as clothes are easy to absorb dust. In an environment where dangerous goods are scattered, fiber static electricity may also cause accidents such as fire and explosion. Therefore, the study of antistatic fibers and conductive fibers has become a problem related to the national economy and people's livelihood. [0003] There are many ways to mak...
