AI Technical Summary

Technical Problem

Traditional nonwoven fabrics lack stretch and recovery properties in clothing products, are heavy, have poor drape, and have a rough feel. They also have insufficient thermal insulation performance when improved thermal insulation is required, and their symmetrical surfaces are not suitable for clothing products.

Method used

The composite nonwoven fabric structure includes a first entangled fiber web, a second entangled fiber web, and an elastomer layer located between the two. The entanglement and offset of fibers are achieved by forming discrete chemical or thermal bonding sites on the first entangled fiber web and forming an asymmetric finish using gravure printing or ultrasonic bonding systems.

Benefits of technology

It improves the stretch and recovery properties of fabrics, enhances drape and hand feel, strengthens thermal insulation, and provides an asymmetrical finish suitable for garment products.

Abstract

The present application relates to composite nonwoven fabrics with asymmetric finishes and methods of making the same. Aspects herein relate to a recyclable composite nonwoven fabric with asymmetric finishes suitable for use in garments and other articles and methods of producing the same. In example aspects, the composite nonwoven fabric with asymmetric finishes includes a first face formed at least in part from a first web of entangled fibers and an opposing second face formed at least in part from a second web of entangled fibers. When incorporated into a garment article, the first face forms an outward-facing surface of the garment article and the second face forms an inward-facing surface of the garment article. The first face includes features that make it suitable for forming an outward-facing surface, such as abrasion resistance, and the second face includes features that make it suitable for forming an inward-facing surface, such as a soft hand.
