Do you know the ESD fabric of anti-static clothing?
Anti-static clothing refers to work clothes sewn with anti-static fabrics to prevent the accumulation of static electricity on clothing. It has the characteristics of efficient anti-static and dust-proof properties, thin and slippery, and clear texture. The anti-static clothing fabrics currently on the market include anti-static ultra-clean fabrics and ordinary anti-static fabrics. Anti-static ultra-clean fabrics are usually called "conductive silk", but only conductive silk suitable for clean rooms can be called so. It is an anti-static ultra-clean fabric.
What is the difference between anti-static ultra-clean fabric and ordinary anti-static fabric? The main difference lies in the word "super clean". Since our country has not yet formulated corresponding testing standards for anti-static ultra-clean fabrics and anti-static fabrics, the selection of anti-static ultra-clean fabrics can only be selected by each application unit based on experience based on the requirements of the working environment. When we choose anti-static ultra-clean fabrics, we must first understand some basic knowledge about the fabrics. When purchasing, we can use a surface resistance tester to measure the resistance values of the warp and weft conductive wires of the fabric and compare them. If If the resistance in both directions is the same, it means that this kind of fabric may have used anti-static agent and the performance cannot be maintained for a long time, so the measured resistance cannot be used as a reference; if the resistance in the two directions is different, our comparison principle is: Select The resistance is relatively small; at the same time, the ultra-clean fabric of anti-static clothing must have the following three functions:
1. With anti-static function
The anti-static performance must be long-lasting and efficient, and will not be significantly attenuated by daily washing and friction.
2. The fabric itself does not generate dust
Since it is worn in a dust-free clean room, it is required that the fabric cannot become a source of dust in the dust-free clean room. This determines that ultra-clean fabrics can only be produced with chemically synthesized long fibers, and the selected chemical fibers must be strictly controlled. The amount of dust generated by the filament. Although cotton, linen, silk and other raw materials can naturally make fabrics more wearable, these short fiber raw materials cannot be used in ultra-clean fabrics.
3. The fabric must have good dust filtering properties
The dust in a dust-free room mainly comes from the air flowing indoors and the human body moving indoors. Improving cleanliness means controlling the tiny dust generated by the human body in the clothes to the maximum extent, and preventing it from passing through the fabric and entering the air.
