Anti -static clothing fabric characteristics
Anti -static clothing used in anti-static clean fabric is commonly referred to as " conductive silk ." In fact, this argument is not tight, conductive silk according to the technical characteristics of their own can be divided into suitable anti-static (ESD) , and applied to the clean room (Clean Room) , only applies to cleanroom conductive silk be called is anti-static clean fabric. Anti -static clothing What is anti-static fabric ? After processing anti-static fabrics can be called anti-static fabric.
Anti -static clothing processing methods usually are: ① antistatic finishing agent for fabric finishing ; fiber fabric grafted ② to improve absorbency for the purpose of hydrophilic fibers blended and interwoven ; ③ blended or woven inlay conductive fiber ; mechanism former two methods are improved fabric moisture regain , reducing insulation, accelerate static leakage. So if in a dry environment , or after repeated washing , the processing effect or not durable or not significant, usually applied on the fabric used in ordinary clothing . Only the third approach to sustainable and efficient solution to the problem of textiles static , it is widely used in the production of anti -static clothing. After finishing as antistatic finishing agent .
Anti-static fabric can be woven fabrics, such as silk conductive , anti-static T / C fabrics, can also be knitted fabrics, knitted gloves , such as anti-static cloth , anti- electric knitted underwear. In addition to anti-static fabric must comply with common technical standards for textiles , but also must have good antistatic properties to meet the needs of production and safety. Refer to the technical requirements of GB12059-89 synthetic anti-static properties of silk " electronic industry
The difference between anti-static clean fabric and general anti-static fabric mainly lies in the concept of " clean " is . Anti-static clean fabric must have the following three features : with anti -static function : Static electricity can attract dust , and to dust adsorbed in the air shower can not easily be blown away. Therefore , the primary anti-static clean fabric characterized as having anti-static properties. Meanwhile , the anti-static properties must be durable , efficient, and not because of the daily washing and friction significantly attenuated.
The fabric itself does not dust : because it is dressed in a clean room , thus requiring cleanroom fabric can not be a source of dust , which determines the length of the fibers clean only fabrics produced by chemical synthesis . And cotton, linen, silk and other natural fibers can not be applied to short- clean fabric, although these materials can make the taking of the fabric better . Also requires the selected filament must strictly control the amount of dust . In general, not suitable for dull polyester filament woven anti-static clean fabric. Because the production of polyester matting agent added - titanium dioxide will become sources of pollution.
Fabrics have a good dust : the clean room dust flowing mainly from indoor air and indoor activities in the human body . When the device determines the conditions to improve cleanliness is required to maximize the control of microscopic dust produced by the body in clothes , let it pass through the fabric into the air. This is called the fabric dust rate is higher . Dust rate at the expense of improving the permeability of the fabric for the price, and therefore relatively knitted fabrics and woven loosely woven fabric is not available for clean room
