Abstract

The invention provides a zipper which comprises teeth, a puller and cotton tapes. The teeth are arranged on the cotton tapes which are aramid fiber cotton tapes or carbon fiber cotton tapes. The cotton tapes are made of aramid fiber materials or carbon fiber materials. The aramid fiber materials and the carbon fiber materials have good fire resistance. The aramid fiber materials or the carbon fiber materials are adopted to make into the cotton tapes which are high in fire resistance and can reach the highest-level index requirements in BSEN531 standards (flame retarding standards of protective suits of operating workers under high-temperature environments). The carbon fiber is higher in strength and better in corrosion resistance. Meanwhile, due to the fact that the cotton tapes are made of the aramid fiber materials or the carbon fiber materials, the processes of adding flame retardants to raw materials and carrying out carrier dyeing in the production process are eliminated, the color fastness of the cotton tapes is greatly improved and the process is simplified. Therefore, the cotton tapes made of the aramid fiber materials or the carbon fiber materials greatly improve the fire resistance and usage performance of the zipper.

for heat-resisting quantity and the anti-flammability that improves slide fastener, can adopt copper or kirsite in metal material to make pull head in slide fastener and tooth, the anti-flammability of metal is fabulous, thereby this design can improve the quality of slide fastener to a certain extent, but the strap in slide fastener generally adopts the dacron thread material, its inflammability is very high, belong to combustibles, after adding flame retardant according to prior art in the dacron thread material, the anti-flammability of this dacron thread material slide fastener is improved really, but the strength character of dacron thread has part to descend, dyeing dye uptake and ordinary polyester silk have the aberration difference of half grade, flame retardant effect does not reach the highest standard requirement of the BSEN531 of European Union (operative employee's protective clothing flame-retardant standard under hot environment) yet, and the halogen element in flame retardant belongs to not environmental protection element abroad, thereby adopt the flame retardant whole structure undesirable.

Therefore, provide a kind of slide fastener, with heat-resisting quantity and the anti-flammability of effective raising slide fastener, and do not affect the performance of slide fastener itself, improve simultaneously the serviceability of slide fastener, become those skilled in the art's problem demanding prompt solution.

Summary of the invention

The invention provides a kind of slide fastener, can effectively improve its heat-resisting quantity and anti-flammability, and do not affect the performance of slide fastener itself, greatly improved the performance of slide fastener use simultaneously.

Slide fastener provided by the invention comprises tooth, pull head and strap, and described tooth is arranged on described strap, and the strap of wherein said slide fastener is aramid fiber strap or carbon fiber strap.

Preferably, in above-mentioned slide fastener, described tooth is the metal tooth, and described pull head is the metal pull head.

Strap in the disclosed slide fastener of the present invention adopts aramid fiber or carbon fibre material to make, itself just has good anti-flammability aramid fiber material and carbon fibre material, and then it is very high to get the strap anti-flammability that one of this bi-material makes, can reach level index request the highest in the BSEN531 of European Union (operative employee's protective clothing flame-retardant standard under hot environment) standard, and the intensity of carbon fiber is higher, and corrosion resistance is better; Simultaneously, adopt aramid fiber or carbon fibre material to make strap, avoided adding in the raw material in flame retardant and production technology the process to carrier dyeing, greatly improved the color fastness of strap, simplified technique, as seen, the strap of aramid fiber or carbon fibre material has improved the fire-retardant and serviceability of slide fastener greatly.
