1. Finish with antistatic finishing agent
In the process of chemical fiber processing, such as polyester, polypropylene, rayon and nylon, the antistatic oil is used to eliminate the danger of static electricity. The mechanism of action is to increase the moisture regain of the fabric, reduce the insulation, and accelerate the electrostatic leakage. Therefore, in a dry environment or after repeated washing, the processing effect is not durable, or inconspicuous, and is usually applied more on ordinary fabrics. Non-durable antistatic treated fabrics whose antistatic properties are greatly affected by ambient temperature and humidity.
2. Improve the hygroscopic properties of synthetic fibers
1). Aggregation
A hydrophilic and conductive component is introduced on the hydrophobic synthetic fiber macromolecular backbone.
2). Blending
In the polymerization and spinning, an antistatic synthetic fiber can be obtained by mixing a high polymer or a slice thereof with an antistatic component.
3). Composite spinning
The composite spinning method can improve the antistatic property of the synthetic fiber while improving the other properties of the synthetic fiber. For example, the polyacetamide mixed with polyethylene glycol is used as the core and the polyester/polyamide composite fiber. The fiber not only has good antistatic properties, but also has improved hand, moisture absorption, abrasion resistance, elasticity, and cohesion.
4). Graft copolymerization
Graft modification of fibers can also improve the antistatic properties of synthetic fibers. For example, polyester is grafted with acrylic acid, and its antistatic durability is better than that of the general method.
3. Blended or inlaid conductive fibers.
1). Use conductive fibers to blend with conventional fibers to improve antistatic properties.
The conductive fiber is prepared, and a small amount of conductive fiber is mixed with the conventional fiber, blended and interwoven, and the electric fiber is used to discharge or corona discharge, effectively dissipating the electric charge, and eliminating the clothing through the corona discharge and leakage of the conductive fiber. Static electricity on. Since the stainless steel fiber is a metal fiber, the antistatic fabric woven therefrom has stable electrical conductivity and does not vary with the number of washings.
2). Inlaid conductive fiber
A composite conductive yarn made of carbon black as a conductive filament can also be used for weaving an antistatic textile.
From the current experience, composite organic conductive fibers are most suitable for the manufacture of permanent antistatic textiles. Such as dust-proof clothes, explosion-proof dust-removing supplies, electromagnetic radiation materials. Among the three methods, only the third method can solve the static problem of textiles permanently and efficiently.
