In some occupations, protective clothing is mandatory and must protect users from possible injury. Therefore, clothing must be made of functional textiles that can withstand extreme external influences – everything from fire to harmful chemicals. The most suitable threads for protective clothing are K-Tech, N-Tech, and Nc-Tech.

Outdoor fabrics are directly exposed to changing weather conditions, so they must provide reliable protection against heat, moisture, rain, and other precipitation. This is especially true for tents, where the thread must be robust, resistant to wind and external weather conditions. The most suitable thread is Serafil WRe, and Rasant WRe is also used as an alternative.

Lifting systems include various lifting straps that are exposed to high tensile forces and wear. Xtreme-tech thread is used, and Serabond, Gore Tenara and Strongbond can be used as alternatives.

Composite materials include carbon fibre and fibreglass fabrics. These materials are lightweight and extremely durable. They are mainly used in the automotive, aerospace, and shipbuilding industries. In the field of composites, the most suitable thread is Serafil.

The most suitable thread is Silver-tech.

Filters used in textiles must be resistant to various chemical conditions, such as wet and dry filtration and hot or liquid gas filtration. Threads that are most commonly used: PP-tech, which has a high resistance to chemicals; D-tech with a high resistance to alkalis and acids and a temperature resistance of up to 125 °C; and Zyex, which has a high resistance to alkalis and acids and a temperature resistance of up to 250 °C.
