The selection of sewing thread, conductive rib, dust-free buckle, conductive belt and other work clothes accessories is very important in the preparation of anti-static work clothes.
When the anti-static fabric is processed into work clothes, the fabric must be cut into clothing pieces, so the fracture of some conductive wires is inevitable, in order to avoid the interruption of electrical conductivity caused by the splicing of materials, a special sewing thread made of silver-plated fiber and polyester filament can be used to ensure the current conductivity of anti-static overalls.
The influence of guide wire on antistatic work clothing is mainly caused by the friction between wire and machine needle, thread and fabric. In addition, the friction between sewing thread and fabric will shed fine fiber dust, which will have a certain impact on the antistatic performance of overalls.
At present, in order to make exorbitant profits, some unscrupulous traders in the market even use printed ink lines as conductors, while the conductors that play a leading performance are ignored.
Many enterprises in the procurement of anti-static overalls, flame retardant clothing, acid and alkali clothing, will ask your enterprise has three certificates and one standard? However, in many cases, the purchasing personnel are not particularly clear about what it is for three certificates and one bid.
Three certificates and one standard for anti-static overalls:
Three certificates and one standard: the three certificates refer to the production license, product qualification certificate and safety identification certificate, and the first certificate refers to the safety mark. This three certificates and one standard originally in the production of anti-static overalls, flame retardant clothing, acid and alkali clothing is necessary when the relevant qualification certificate belongs to the national standard, but in fact, as early as a few years ago, the country has clearly cancelled the safety identification certificate and safety mark. Although this is true, many enterprises will still let them provide these in the bidding procurement process.
At present, in the production process of anti-static overalls, flame retardant clothing and acid-alkali resistant clothing, the safety identification certificate has been completely lost, but the safety mark is still in the process of being extended.
