Problems solved by technology

However, the addition of conductive filaments and conductive fibers will affect the softness and wearing comfort of the fabric, especially the itching caused by the protruding conductive material is even more unbearable; Electrostatic properties
The more obvious disadvantage is that the content of conductive yarn and conductive fiber blended with other fibers is low, so the amount on the surface of the fabric is very small, thus affecting the conductive and antistatic properties of the fabric.

Abstract

The invention relates to a production method of a conductive pure-cotton fabric and belongs to the field of functional textiles. The production method comprises following steps that 2.5-15 g of sulfonated polyether ether ketone, 5-17.5 g of hydrogen donor polymer, 1-10% by weight of cross-linking agent, an appropriate amount of acetic acid, finishing liquid having the pH regulated to be 2-5 and the balance deionized water are prepared into 1 liter of solution; a pure-cotton fabric is dipped in the finishing fluid for 30-50 minutes and then is subjected to one-time dipping and one-time pressing through a padder, the squeezing rate is 70-110%, and the bath ratio 1:15; pre-drying is performed in a drying oven at the temperature of 80-90 DEG C for 20-40 minutes, and baking is performed in a baking machine at the temperature of 130-160 DEG C for 60-240 seconds; dipping is performed in 0.1-0.3 mol / L of copper salt solution for 10-15 minutes, then one-time dipping and one-time pressing are performed through the padder, the squeezing rate is 60-80%, and the pure-cotton fabric is arranged in a photochemical reactor after vacuum drying and is exposed to 350 nm of ultraviolet light. The conductive pure-cotton fabric is soft in hand feeling and excellent in conductive performance and can be used in the fields of electric conduction, electromagnetic shielding and the like.

Description

technical field [0001] The invention relates to a preparation method of a conductive pure cotton fabric, which belongs to the field of functional textiles. Background technique [0002] Textile material is an electrical insulator material, and its specific resistance is generally high. During the wearing process of textiles, due to the close contact and friction between fibers and fibers, charges are transferred on the surface of the object, resulting in static electricity. In recent years, with the rapid development and popularization of computers, telecommunications, microwave ovens, etc., static electricity and electromagnetic radiation in people's living and working environments are becoming more and more serious. brought many negative effects. In order to solve the electrostatic interference of fabrics during wearing, the fibers and their fabrics must have durable antistatic properties. There are many ways to impart durable antistatic properties to fibers and their fa...
