For heat-resistant seams.
Salta K are special yarns made from 100% aramid (DuPontTM NOMEX). Ideal for protective clothing (e.g. firefighters, metalworking, foundries), light tarpaulins and items of equipment requiring a high degree of heat resistance.
Product advantages:
- High temperature resistance
- Can be exposed to high temperatures, up to 360 ° C for short periods of time, the filament will not melt
- The thread extinguishes itself, provided it is no longer exposed to flame
- Low flammability
- Good chemical resistance to weak acids and alkalis


In the clothing industry, thread plays no less a role than fabric or leather. The strength of seams, the durability of a product, and its appearance depend on thread. In the production of specialized products—protective clothing, technical textiles, footwear, or camping equipment—special properties are essential: resistance to high temperatures, mechanical stress, and chemical influences.
Salta K 120 aramid thread was created precisely for these tasks. This modern, high-tech product is used in industrial sewing where conventional polyester or polyamide threads fail. Thanks to its unique composition and construction, this thread exhibits outstanding properties that ensure the reliability and durability of the final product.
