Various anti-static characteristics of functional fabrics
Anti-static, clean fabric
Also known as "conductive silk", the use of polyester as the main, dedicated high-performance polyester filament and permanent conductive fiber weaving made by a special process, or by weaving through the embedded, weft weaving conductive fibers embedded. With such a fabric made of a special garment sewing process has an excellent anti-static dust-performance, high efficiency, permanent anti-static, dust-proof performance and soft, thin, smooth, textured clear features, mainly for the production of dust clothing, anti-static garment, to discharge corona discharge or leakage effects, different specifications of the fabric to adapt to different anti-static or a clean environment, for example, 100D × 100D of the conductive silk for 10 000 -30 10 000 class clean the Environment and 75D × small box 100D, 75D × 75D small squares; 75D × 75D applies to 1000 clean environment requirements.
Scope: The medical, pharmaceutical, food, precision instruments, aerospace and other more sensitive to static electricity
Sense of cleanliness and demanding industry.

Ultra-clean anti-static fabric
The use of special polyester filament yarn, woven by the weft embedded conductive fibers, made by a special process, not only
There are excellent anti-static function, but also effectively prevent the fabric fiber loss, as well as fine dust particles leaking from the cracks in the fabric, and has not the environmental impact (high temperature), chemical stability (resistance to washing)
And other features. Product specifications for the 68D × 75D cells for 10-100 cleanrooms widely microelectronics, optoelectronics, precision instruments, aerospace and other static-sensitive and require a higher degree of cleanliness of the industry.

Anti-static knitted fabric
Series of conductive fibers and the use of special polyester filament formed by the knitting process. Anti-static knitted fabric can not only eliminate static electricity and dust is not fat, but an ordinary knitted fabric breathable, warm, comfortable features, meet the health requirements of a new generation of anti-static fabric.
Scope: commonly used in the processing of anti-static gloves, anti-static underwear.
Anti-static dust-proof fabric
In short thin polyester cotton yarn fabrics conductive fibers woven into the middle distance (spacing 1.2cm), order made by a special process, the fabric density than ordinary fabric, with anti-static, anti-blasting capabilities. Wear this fabric strong, soft and comfortable, moisture permeability, can be processed into a variety of
High-grade anti-static cotton overalls, suitable for storage and transportation, chemical, gas, oil, coal, marine, aerospace, military, and other flammable operating environment.

Anti-static clean fabric - conductive fiber
Ultra-clean anti-static conductive fiber is the key ingredient in the fabric, its performance is good or bad, on the one hand determines the fabric anti-static properties; the other hand, the amount of dust and fabric related. The development of conductive fibers so far has gone through three stages: the first stage of metal fibers. Metal fiber conductive properties, heat resistance, chemical corrosion. But for textiles, metal fibers hold together a small, spinning performance is poor, poor coloring products, feel bad, it only applies to woven T / C fabric, in the oil fields, chemical plants, flammable, explosive industry to work on taking . The second stage is the type of organic conductive fiber surface carburization, represented by the product of BASF Corporation Resistat. Way through the conductive surface carburization added to the toner surface is formed of nylon, which is characterized by relatively low surface resistance, but the conductive toner vulnerable to the effects of friction and washing off from the nylon surface, so that the conductive fabric performance decreased. Meanwhile, the falling down of conductive toner dust in the room is clean, and electronic products will cause harm. The third stage is the type of organic conductive fiber composite spinning (the second generation of organic conductive fibers), the representative product for the Japanese Kanebo's Belltron, especially Kanebo's latest development 9R, BR series. Organic conductive fiber composite spinning conductive toner is melted and the base material after mixing, with a special spinneret holes and into the fiber matrix composite materials, forming a conductive bicomponent fiber. The performance characteristics of their products will not friction, which results in carbon particles washed off with a good washing, anti-bending, anti-wear properties. At present, most of the production anti-static clean fabric choices are BASF's Resistat, but in Class 10000 clean environment than in cementite-type fiber is not applicable, can only use composite conductive fiber spinning. Such as the same type of conductive fiber composite spinning, to compare their structure, carbon and mixed matrix material completely melted in the fiber outer coating (such as Kanebo Belltron 9R1, BR1) conductive fiber, because the conductive surface area with the largest of its best conductivity, it should be ultra-clean anti-static fabric of choice. In addition, the conductive fiber holes (D number) and the conductive fiber and filament conductive fiber work conditions also have a great impact on performance. The same structure of the conductive fiber, the more holes, the larger conductive surface area, conductivity will be. With a conductive fibers in the composite on different devices (and wires) the effect is not the same. In the high-powered magnifying glass we can see some ultra-clean anti-static conductive filament fabrics floating in the fabric surface, this is because when the conductive filament composite caused by uneven tension control. Floating on the surface of the conductive wire hook can easily be broken, then the loss from the fabric, not only affects the conductivity, and destruction of cleanliness. Therefore, we should choose the original as possible and wire conductive fibers.
