1. Increase the humidity so that the surface of antistatic fabric has moisture retention properties, which can reduce the surface resistance of the fabric .
In order to reduce the risk of static electricity, increase the humidity in the venue and reduce dust, flying flowers, hairiness, etc. It is difficult to maintain a certain level of humidity in finished textile products. This method can also be applied by coating a layer of hydrophilic polymer surfactant (antistatic agent) on the surface of the fiber, and can also be classified into the third “auxiliary” method. It is characterized by simple process and low cost, but it is not resistant to washing and is greatly affected by the relative humidity of the air.
2. Reduce surface resistance.
This method uses conductive fibers as raw materials for textile products to reduce the risk of textile fabrics and clothing. The role of surface resistance of other products. With the deepening of research, conductive fibers include organic polymer fibers, mainly polyamide or polyester, and inorganic fibers, including the more commonly used carbon fibers and stainless steel fibers. Conductive fibers need to be spun and then woven into cloth. The conductivity of the fiber depends on the type, amount and location of the conductive substance to be adjusted. Carbon fiber is a more commonly used conductive material, copper sulfide, copper iodide and other oxidized materials. Metal is also commonly used. The conductive substance can be covered on the outer layer of the fiber using a method similar to coating processing, or composite spinning can be used to make the fiber contain conductive material, or part of it is distributed on the surface and part is formed inside the fiber to form two media. Conductive materials are usually The addition amount is between 3% and 30%. In recent years, with the improvement of ecological safety requirements, consumers have paid more attention to the heavy metal content in textiles, especially the promotion of the Oeko-Tex Standard 100 standard of the International Environmentally Friendly Textile Association. Some of the original metals are conductive. The application of fibers in antistatic fabrics has a downward trend.
3. Adding auxiliaries, including adding antistatic agents to spinning oils, functional finishing auxiliaries, new antistatic softening finishing agents, etc.
The newly launched antistatic agents in foreign markets include: Crostat PTA, which is a temporary antistatic agent for synthetic fiber carpet yarn. Does not affect the color fastness of carpet yarn; TC-Anfistatikum Uk flussig is a special antistatic agent for synthetic fibers, which can make the fabric feel softer; Laustat cT is an efficient antistatic agent for soaking and padding; Yamsoft -GS is a pseudo-cationic soft lubricant with antistatic properties. It is specially used for cotton yarns, but can also improve the softness and antistatic properties of synthetic or blended yarns; AchitoilOL Conc is a non-ionic antistatic agent. Used for cellulose fibers and their blended yarns, it has high lubrication function and reduces friction between fibers.
For new antistatic functional additives, due to their good macromolecule flexibility, large inter-atomic bond distance, large degree of freedom of movement, and intermolecular interactions, The force is weak, showing low surface tension, good lubricity and softness. For wool fibers, the two-way friction coefficient of wool fibers is changed to make it nearly consistent, effectively preventing the irreversible movement of wool fibers. For polyester fiber, because the antistatic agent macromolecules have a greater affinity for the polyester fiber macromolecules, it gives the polyester fiber a smoother and softer feel. Experimental results show that in addition to reducing the problem of static electricity, the new antistatic agent can also reduce fiber buckling hysteresis, improve the drape of antistatic fabrics, and obtain a soft feel.
The anti-static fabric produced by City Textile mainly embedding conductive fibers in the fabric. Gives fabrics permanent anti-static properties.
