Problems solved by technology

This type of method is simple and easy to operate, but its antistatic effect is not long-lasting, especially in low-humidity environments; (2) Using blended interweaving to mix conductive fibers into nylon textiles, this method has stable conductivity and is not limited by climatic conditions , but it involves physical and mechanical processing, the process is complicated, and the finished product feels bad
Generally, after oil-repellent and water-repellent treatment, the fibers are hydrophobic and do not have antistatic properties.
[0004] Chinese patent CN101492885 discloses an antistatic film-like resin-wrapped fiber containing polyamide textiles. The surface of the single fiber of the textile is wrapped with an antistatic film-like resin layer. After washing 20 times according to the JIS L 0217 No. 103 standard According to the JIS L 1094 standard, the friction band voltage of the textile is below 3000V. This patent solves the antistatic and durability problems of nylon textiles by adding conductive particles to film-forming agents such as polyether polyurethane, and does not improve Its water and oil repellency and its durability

Abstract

The invention discloses an antistatic nylon textile. A coating resin layer is covered on the single-fiber surface of the textile, and the coating resin layer is formed by polyether type polyurethane resin and fluorine-based resin, which perform cross-linking reaction with a terminal group of nylon fiber. The initial friction-charged electrostatic potential of the textile is below 2000V, the water repellent degree is above grade 4, and the oil repellent degree is above grade 4; and the friction-charged electrostatic potential after 20 times of family washing is below 2500V, the water repellent degree is above grade 3, and the oil repellent degree is above grade 3. The antistatic nylon textile disclosed by the invention fills in the blank that the nylon textile can not integrate the antistatic performance and the water-repellent and oil-repellent performance simultaneously.

Description

technical field [0001] The invention relates to a nylon textile with antistatic properties, in particular to a nylon textile with antistatic, water-repellent and oil-repellent properties and excellent washing durability. Background technique [0002] Nylon textiles have properties such as friction resistance, bending deformation resistance, low wrinkle resistance, and quick drying after moisture absorption, and are widely used in various fields such as clothing, carpets, towels, artificial leather, fishing nets, and fishing lines. However, its poor antistatic property and water and oil repellency have brought a lot of inconvenience to use. [0003] It is very difficult to have two opposite properties of antistatic and water repellency and oil repellency at the same time and have washing durability, and it is extremely difficult to keep both properties within a good performance range. Nylon textiles currently on the market only have one of antistatic or oil-repellent and wat...
