High-Loft and Insulation Web Formation
topic
High-loft nonwoven web formation uses crimped hollow fibre or siliconised polyester fibre blends cross-lapped to thicknesses of 20 to 100 millimetres for thermal insulation padding, with light thermal bonding preserving the air-entrapping loft structure that provides thermal insulation through still air entrapment, producing wadding and batting products for quilted outerwear, sleeping bags, and furniture padding applications.
Role
Produces the bulky air-entrapping fibre assemblies used as thermal insulation filling in outdoor apparel, bedding, and furniture applications where high loft from cross-lapped crimped fibre web provides superior thermal insulation through still air retention in the interfibre space, with fibre crimp geometry, hollow cross-section, and siliconised surface treatment governing the loft recovery and thermal performance of the insulation product.
