3), the organic fiber tow of drying being carried out warping, beaming method is identical with weaving process；Tow width is 80-160cm, and every cm density is
20-100 root, every square metre of tow weight is 18 grams to 150 grams；Again the tow in warp beam is wrapped on vacuum coating axle after warping；Organic
Fabric is not required to warping, is directly wrapped on vacuum coating axle after drying；
4), by above-mentioned matrix select one and put into vacuum chamber, matrix distance target plane 50mm, use the method Sputter Deposition of Chromium of vacuum magnetron sputtering coating film；
It is evacuated to 1.1 × 10 by intrinsic pressure for vacuum chamber-2Pa to 1.5 × 10-2Pa, then passes to argon, and its flow is 200 to 260ml/min, at this moment in vacuum chamber
It is pressed in 1.8 × 10-1Pa to 2.4 × 10-1In the range of Pa；Voltage and current between the two poles of the earth is adjusted to the scope of 330 to 450V and 3 to 100A
In, the matrix speed of service is 0.6 to 3m/min, and plating densities is 0.4-3 gram/m2, matrix surface resistance is 0.1 to 100000 Ω/em2
5), above-mentioned matrix rinsed, dry metering packing.
Further scheme is: from the matrix of vacuum chamber chromium plating ionic membrane, then with the method thickened chrome-plating layer of electroplating plastic, 3 to 20 grams/m2；Base
Surface resistance is 0.01-500 Ω/cm2。
The present invention compared with prior art, has a following excellent results:
1, compared with existing bronze mirror conductive fiber and fabric, there is more excellent conduction, heat conduction, lead wet, antibacterial and deodouring, reflection infrared ray merit
Energy；The advantage with folding wear-resisting, washable, anti-.
2, the chromium plating fiber of this method processing is that circumference is coated with chromium entirely, and adhesive force is excellent, unit volume chrome content high, and this feature is better than current city
Chromium plating fiber product on field, including imported product.
3, compared with chemical plating chromium process, have pollution-free, can produce continuously, low cost, stay-in-grade advantage.
This invention metal chromium ions and organic fiber adhesion is strong, pollution-free, low cost, can produce continuously.Product for electronics, military project communication,
The industries such as medical treatment and extraordinary weaving.Such as electronic shield product, military shielding tent, extraordinary weaving anti-biotic material and civilian health-care textile product.
