In the production of clothing, footwear and technical textiles, the quality of the seam determines the durability and reliability of the product. This is especially true when sewing products from heavy fabrics, leather, furniture upholstery, protective equipment or products intended for intensive use. This is where Perma Core 36 from Gütermann comes to the fore – an industrial polyester thread of increased strength that can withstand extreme loads.
Perma Core 36 thread is an ideal combination of strength, abrasion resistance and manufacturability. It is indispensable in cases where an especially strong seam is required – when sewing work suits, shoes, covers, special clothing, equipment and other products that have high performance requirements.
Advantages
1. Exceptional strength
Perma Core 36 is designed to create seams that can withstand serious mechanical loads. It is the optimal choice for heavy items where strength is critical – shoes, bulletproof vests, belts, backpacks, awnings.
2. Stability at high speeds
The thread works perfectly on industrial sewing machines – single-needle and multi-needle, chain and shuttle stitch. Even at a speed of over 5,000 stitches per minute, it maintains a stable feed, does not twist or cause breaks.
3. Resistance to chemicals, water and UV
Polyester in the thread is resistant to aggressive substances – oils, acids, alkalis. Perma Core 36 also does not fade in the sun and does not deform during long-term use outdoors, which makes it ideal for outdoor equipment, technical awnings and automotive textiles.
4. Excellent layability
Thanks to the balanced twist and high quality of processing, the thread easily lays in the fabric, forming a clean, dense and uniform seam that is resistant to stretching and tearing.
5. Reliability and cost-effectiveness
Perma Core 36 reduces the number of machine stops due to breaks, which means it increases productivity and reduces equipment maintenance costs. Its reliability is especially appreciated in mass production.
