The utility of the clean clothes is declining with the use time, ensuring the durability of the dust-free performance, not only helping to reduce the frequency of replacement of the clean clothes, reducing the production cost, and more importantly, preventing the dust-free clothes from being used. The damage caused by the failure within the production. The durability of the clean clothing needs to be considered in terms of durability of the cleaning performance and durability of the electrostatic performance. The main indicator of the durability of the clean performance is the pilling grade of the fabric, reflecting the change in the surface caused by the fabric rubbing for a certain period of time under the prescribed procedure. In the process of friction and pilling, the fiber is easy to break and pilling, and particles are generated, which pollutes the clean room environment. The fiber breakage will cause the local filtration efficiency of the dust-free clothing to drop, and the dust filter requirement cannot be met.
Common problems: 1. The quality of the anti-static fiber. The problem of the quality of the wire is caused by uneven tension control. The conductive wire floating on the surface is easily broken off, which will then fall off the fabric, which affects both the electrical conductivity and the cleanliness. 2. Use the hook of the hook and loop fastener to face the fixed position of the garment to exert friction, observe and contrast the friction and fluff of the two garments, and also preliminarily judge the pilling of the dust-free clothing fiber; 3. The fabric with long floating length Organization, due to the small traction between the fibers, easy to pilling; 4. fabrics with insufficient warp and weft density, also easy to pilling; 5. In high-grade clean clothing, should use the hook and loop as little as possible, can be used Metal button to adjust the tightness.
