Supply to meet EN1149-3 standard metal conductive yarn
 

Product description:

Anti-static, anti-electromagnetic radiation fabric is mainly used for protecting the human body, so that the fabric should have good antistatic and electromagnetic wave reflection data show that domestic and foreign technology, shielding fabric are mainly two: one is the metal fabric, In ordinary chemical fiber or natural fiber fabric coated with a layer of metal, such as nickel, silver, copper, etc., this fabric is washable poor, with the increase in the number of washes, the shielding decline; the other is the use of metal wire woven into the fabric of the network as a three-layer shield, inside and face the common fabric, the middle laminated metal mesh, this fabric can not be washed with water, and heavy. We developed a resistance to washing, light weight, small size yarn low price shielding fabric used, we chose stainless steel fibers as shielding material, the fiber is not only in a certain range of the electromagnetic waves reflected outstanding performance, but also to meet the spinning, weaving, sewing and other processing requirements in line with exports to the EU testing standards EN1149-3 above criteria. The stainless steel fibers subtle 'soft features and good flexibility, and has good mechanical properties, electrical conductivity, corrosion resistance, heat resistance. We also after repeated experiments, Final selection of 6-8 microns in diameter, steel 304 or 316L stainless steel fibers, while taking into account the shielding fabric wearing comfort, strength, re dyeing and other characteristics, we chose the natural fibers of cotton, synthetic polyester staple fiber and stainless steel fiber composite made of three anti-static, anti-electromagnetic radiation yarn. Considering the stainless steel fiber is expensive, should seek to balance cost and effectiveness, through trial and error, we worked out a blending ratio both economical and reliable stainless steel fibers, in general, By 20% -30%, the shielding efficiency can reach 30-40dB. Considering the taking of comfort and fabrics crisp, easy to wash, quick drying, easy to dye, and other factors inexpensive polyester staple fiber and cotton ratio of 35% -40% in line with exports to the EU standard EN1149-3
