Nonwoven Crimping Material

World’s First Nonwoven Crimping Material

Softer nonwoven from polyester staple fiber for the shoe industry

Given its strong influence on wearability characteristics, crimping material is an important component in the production of shoes. Consumers are expecting more and more from modern shoes such as ankle boots; shoes must satisfy the demands of fashion and at the same time be comfortable to wear. Shoe manufacturers are therefore faced with major production-related challenges. The new nonwoven crimping material which is currently in the patenting process combines high shape retention, cut edge durability, and a soft, flexible material feel.

Advantages for shoe manufacturers

In contrast to conventional knitted crimping materials, manufacturers can cut the lining to size irrespective of direction, which reduces waste by up to 10 percent. This is possible since the innovative nonwoven made of polyester staple fibers stretches uniformly both in a longitudinal and transverse direction. Its plastic deformability which is faster than warp knits of 100 percent cotton reduces production time and thereby lowers production costs. Despite the very fine fibers which lend the material its pleasant feel, the crimping material is characterized by a high cutting-edge stability. This is an additional plus for manufacturers since it opens up a range of new design options. “Manufacturers will also profit from the improved shape retention, last-true vamp mold retention and optimum shape and stability”, explains Thomas Arnold from Product Development at Freudenberg Performance Materials.

Optimum wearing comfort

For wearers of the shoe, the new crimping material is characterized by its noticeably greater wearing comfort. The material’s extremely fine fibers lend a comfortable, soft wearing sensation. Furthermore, they significantly reduce the grammage of the crimping material and thereby reduce the weight of the finished shoe.
