Main fabric of anti-static clothing
Anti-static clothing refers to work clothes that are sewn with anti-static fabric as a fabric to prevent static electricity accumulation on the clothing. It has high-efficiency anti-static, dust-proof performance, thin and smooth, and clear texture. Anti-static clothing on the market now has anti-static ultra-clean fabrics and ordinary anti-static fabrics, while anti-static ultra-clean fabrics are often called "conductive silk", but only conductive silk suitable for clean rooms can be called It is an anti-static and ultra-clean fabric.
What is the difference between anti-static and ultra-clean fabrics and ordinary anti-static fabrics? The difference lies mainly in the word "super clean". Since our country has not yet developed corresponding anti-static ultra-clean fabrics and anti-static fabric testing standards, the selection of anti-static ultra-clean fabrics can only be selected by each application unit based on the requirements of the operating environment. When choosing anti-static ultra-clean fabrics, we must first understand some basic knowledge about fabrics. When purchasing, you can use the surface resistance tester to measure the resistance values of the warp and weft filaments of the fabric separately, and compare them. The resistance in both directions is the same, indicating that the fabric may be antistatic agent, the performance can not be maintained for a long time, then the measured resistance can not be used as a reference; if the resistance in the two directions is not the same, our comparison principle is: choose The resistance is relatively small; at the same time, the ultra-clean fabric of the anti-static clothing must have the following three functions:
1. With anti-static function
Antistatic properties must be long lasting, efficient, and not significantly attenuated by daily washing and rubbing.
2. The fabric itself does not dust
Because it is worn in a clean room, it is required that the fabric cannot be used as a dust source in a clean room. This determines that the ultra-clean fabric can only be produced by chemically synthesized long fibers, and the chemical fiber selected must be strictly controlled. The amount of dust emitted by the filament. Although cotton, hemp, silk and other raw materials can naturally make the fabric more pleasing, these short fiber raw materials cannot be applied to ultra-clean fabrics.
3. Fabrics should have good dust filter
The dust in the clean room mainly comes from the indoor air and the human body moving indoors. To improve the cleanliness, it is required to control the tiny dust generated by the human body to the inside of the clothes. Do not let it pass through the fabric and enter the air. .
