Freudenberg introduces the new cotton-like 37xx PES series interlinings

Weinheim, Germany, June 20, 2023. Freudenberg Performance Materials Apparel (Freudenberg) is pleased to announce the 37xx PES Series – a revolutionary range of interlinings that offer the classic feel of cotton combined with the modern features of enhanced durability, increased yields, and low-temperature fusing. With a 100% PES base and special finish, these OEKO-TEX® STANDARD 100 Class I certified products open new possibilities for the business and smart casual segments. The 37xx PES Series is available for order and supplied from Asia.

Feels like cotton, better than ever

The 37xx PES Series of cotton-like interlinings couples the feel of cotton you know and love with superior qualities and greater consumer safety. Crafted from a 100% PES base with a special finish, these new interlinings boast enhanced durability and better resilience and recovery over traditional cotton interlinings. The 37xx PES Series interlinings offer the added advantages of no visible impurities or foreign fibers, along with low temperature fusing, reducing the risk of yellowing in the finished product. Compared with cotton interlinings, the 37xx PES Series also offers increased yields of up to 150 cm in width and are more cost effective than traditional cotton interlinings, allowing for easier and more efficient manufacturing.

Apart from the material qualities, the 37xx PES Series offers unmatched consumer safety. Produced at its Nantong, China factory, Freudenberg ensures optimal quality control of the 37xx Series. Furthermore, the interlinings are OEKO-TEX® STANDARD 100 Class I certified, making them safe for even the most sensitive skin types, including for babies.

“With the launch of our 100% PES base interlining 37xx Series, we are proud to offer a superior alternative to cotton interlinings. These new products combine the timeless textures and reliability of traditional cotton with enhanced durability, increased yields, improved quality control, and high safety standards. We are proud to add the 37xx PES Series, manufactured in our Nantong, China factory, to our interlinings lineup,” says Merry Chen, Head of Global R&D and Product Compliance, Freudenberg Performance Materials Apparel.

Product applications

The 37xx PES Series currently includes the 3738 and 3755 products, offered in 115 g/m2 and 165 g/m2 weights, respectively. These can be fused with other fabrics and interlinings to create the precise hand feel for garments, ensuring apparel makers have the latitude to craft their apparel needs.
