In the modern clothing industry, the quality and reliability of seams are of paramount importance. This is especially true for industries working with heavy fabrics, products subject to intensive loads, and mass production of clothing. In such conditions, conventional sewing threads may not cope with the requirements for strength and wear resistance. That is why manufacturers choose high-tech solutions, and one of the best options is Perma Core 120 from Gütermann – an industrial polyester thread with a core that combines high strength, resistance to external influences and stable quality.
Advantages
- Increased tensile strength
The thread can withstand heavy loads without deformation or rupture. This is especially important when sewing products subject to stretching, compression and mechanical stress – for example, jeans, workwear, bags, jackets, shoes and furniture. - Consistent seam quality at high speeds
The thread is specially designed for industrial sewing on high-speed machines. Perma Core ensures uniform feed, minimal dust formation and stable stitch formation even at speeds of over 5,000 stitches per minute. - Resistance to chemical influences and washing
Thanks to the polyester base, the thread is resistant to detergents, acids, oils and ultraviolet radiation. This makes it ideal for textiles that are subject to frequent washing, dry cleaning or prolonged outdoor use. - Excellent layability and no twisting
The special structure prevents knots and twists, reducing the risk of breakage during sewing. This is especially important for automated production, where the stability of the thread material directly affects productivity. - Cost-effective
Due to its high strength and low number of breaks, the thread reduces equipment maintenance costs and increases productivity. One cone of Perma Core 120 provides more products with less loss.
