Benefits of technology

This patent relates to two types of fabrics made from a combination of cellulose fiber, polyamide fiber, para-aramid fiber, and biregional fibers. The fabrics have a specific composition and weight, and can also be treated with flame retardant chemistry. The fabrics have good thermal performance and can be woven using warp yarns and filling yarns, with the filling yarns comprising the majority of the FR rayon, para-aramid, and biregional fibers. Overall, these fabrics have improved properties that make them useful in a variety of applications.

Problems solved by technology

However, the fabrics described in the above-mentioned references are expensive, and are uncomfortable to wear.

nd Yarn Samples

[0042]Table 1 lists multiple fabric and yarn samples. Fabric sample 1 is an embodiment of the current invention. Fabric samples 2 and 3 are comparative examples. All three fabric samples were woven fabrics having a twill construction. Fabric sample 1 was woven with yarns comprising 47 weight % cellulose fiber, 14 weight % FR rayon fiber, 16 weight % polyamide fiber, 6 weight % para-aramid fiber, and 17 weight % oxidized polymeric biregional fiber. Fabric sample 1 comprised warp yarns comprising the cellulosic fibers and the polyamide fibers, and filling yarns comprising the FR rayon fibers, the polyamide fibers, the para-aramid fibers and the biregional fibers. In this way, a large portion of polyamide fibers were distributed on the surface size of twill fabrics, while many oxidized biregional polyacrylonitrile fibers and para-aramid fibers that were not dyeable were hidden on the back side of twill fabrics. As a result, durability and appearance of the fabrics was su...

Abstract

Flame resistant fabrics made from yarns of cellulose fiber, polyamide fiber, and oxidized polymeric biregional fiber are provided. The fabrics comprise about 20 to about 90 percent by weight of cellulose fiber, about 3 to about 45 percent by weight of polyamide fiber and about 5 to about 35 percent by weight of an oxidized polymeric biregional fiber comprising an oxidized polymer selected from the group consisting of acrylonitrile-based homopolymers, acrylonitrile-based copolymers, acrylonitrile-based terpolymers, and combinations thereof.

Description

FIELD OF INVENTION[0001]The present disclosure relates to flame resistant fabrics made from yarns comprising cellulose fiber, polyamide fiber, and oxidized polymeric biregional fiber.BACKGROUND[0002]Flame resistant garments are worn by workers exposed to thermal and flame hazards in the workplace such as heat, open flame, and electric arc flash to reduce potential bodily injuries.[0003]Many flame resistant garments are made with 88 / 12 fabrics comprising a blend of 88% cotton fibers and 12% nylon fibers. The fabrics are typically treated with phosphorous-based flame retardant chemicals. The fabrics meet the industrial standards of flammability performance requirements. Further, because the majority of the fabric comprises cotton fibers, the fabrics are relatively inexpensive. In addition, these fabrics are more durable during industrial laundering and wearing as compared to 100% cotton fabrics since addition of nylon fibers to the fabric provides a significant improvement in abrasion...
