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.

Filed:

Apr 25, 2002
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.
