US Patent:

6358608, Mar 19, 2002

Filed:

Aug 8, 2001

Appl. No.:

09/924629

Inventors:

William J. Hanyon - Salt Lake City UT
Michael R. Chapman - Bountiful UT
Tsai Jung Huang - Taichung, TW

Assignee:

Chapman Thermal Products, Inc. - Woods Cross UT

International Classification:

B01F 600

US Classification:

428362, 428364, 428357

Abstract:

Fire retardant and heat resistant yarns, fabrics, felts and other fibrous blends which incorporate high amounts of oxidized polyacrylonitrile fibers. Such yarns, fabrics, felts and other fibrous blends have a superior LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends are also more soft and supple, and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The yarns, fabrics, felts and other fibrous blends incorporate up to 99. 9% oxidized polyacrylonitrile fibers, together with at least one additional fiber, such as p-aramid, in order to provide increased tensile strength and abrasion resistance of the inventive yarns, fabrics, felts and other fibrous blends. The yarns may be woven, knitted or otherwise assembled into a desired fabric.

Appl. No.:

10/132616

Inventors:

William J. Hanyon - Salt Lake City UT
Michael R. Chapman - Bountiful UT

Assignee:

Chapman Thermal Products, Inc. - Salt Lake City UT

International Classification:

D02G 300

US Classification:

428364, 428377, 428379, 428394, 428373, 57243, 57244

Abstract:

Fire retardant and heat resistant yarns, fabrics, and other fibrous blends incorporate one or more fire retardant and heat resistant strands comprising oxidized polyacrylonitrile and one or more strengthening filaments such as metallic filaments (e. g. , stainless steel), high strength ceramic filaments, or high strength polymer filaments. Such yarns, fabrics, and other fibrous blends have a superior tensile strength, cut resistance, abrasion resistance, LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, and other fibrous blends are also more soft, supple, breathable and moisture absorbent and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The inventive yarns may be woven, knitted or otherwise assembled into a desired fabric or other article of manufacture.
