That’s why, since 1864, the company has gathered mastery, developing its own technology and, gradually, launching new developments into the market. Every seam –Gütermann emphasizes- poses specific requirement to the thread”. To confront any contingency, the company has got an outstanding assortment of threads in which the products designed for heavy duty conditions are included. Protective clothing are important, but so are the threads that hold the assembly together, especially when it comes to clothing for extreme applications, such as firefighters clothing, metalworkers and foundries, welders, protective items or combat clothes. In this type of clothing seams are subjected to strains and extreme stress due to fire, heat and chemicals. The meta-aramid yarns optimize protection in areas where protective clothing is weaker, the seams. yarn that is distinguished by its high sewing performance. ·References K 403 and K 753 With the same fire retardant properties as above, K 403 and K 753 are long fiber spun yarns. The advantages of the long fiber technology are uniformity and high breaking strength. An additional feature is the brightness as compared to short fiber spun yarns. ·Threads Salta K 40 / 70 /120 Made with 100% aramid (Nomex ®), they are very resistant to heat and chemicals, making them ideal for protective suits and all areas of thermal applications. Its advantages include resistance for a short period of time at temperatures up to 360° C without melting or creating flame. They are self-extinguishing, offering good chemical resistance to mild acids and alkalis substances. Other high performance yarns ·Mara 80 / 100 Threads made of 100% polyester MCT –Micro Core Technology®- characterized by its extreme resistance to breakage. They are therefore the ideal solution for seams that are confronted to high strains. Mara 100 MCT variant provides optimal security in sewing automata, plus great regularity, no finer or coarser stitches. This range has a WA version: waterproof and dirt-repellent threads, while having high resistance to special treatments. ·GütermannA30/50/80/100 Series of 100% polyester coated yarns. Its optimal field of application are sealing seams and topstitching in fabrics of medium and heavy qualities, such as labour and leisure garments, home textiles and upholstery. Gütermann A has a high resistance to breakage and rubbing, good heat resistance and optimal security in sewing automata. Fireproof threads Based on meta-aramid fibers (Nomex®, Newstar ®), they are fireproof, refractory, and will automatically extinguish when not in contact with the source of the fire. Gütermann fireproof yarns can withstand high temperatures for long periods of time and have accredited excellent resistance to alkaline environments. In the field of fire resistant clothing the following solutions are noteworthy: ·References K 403 AR and K 753 AR These yarns resist for a short time at 360° C, and do not melt, nor burn and self-extinguish. They have good chemical strength to mild acids and alkalis. Gütermann K / AR is a short fiber spun 95
