Filed:

Jul 6, 2000

Appl. No.:

09/610932

Inventors:

Clyde C. Lunsford - Sharpsburg GA
Phillip H. Riggins - Greensboro NC
Michael T. Stanhope - Atlanta GA

Assignee:

Southern Mills, Inc. - Union City GA

International Classification:

D06P 385

US Classification:

8531, 8529, 8574, 8606, 8609, 8611, 8921, 8918, 8925, 8602

Abstract:

Fabric blends of inherently flame resistant fibers and flame resistant cellulosic fibers that contain a flame retardant. According to the method of production of these blends, the inherently flame resistant fibers can be dyed a full shade of color without depleting the flame retardant contained in the cellulosic fibers. In addition, the potential for laundering shrinkage of the inherently flame resistant fibers of the blends is reduced regardless of whether both, one of, or neither of the inherently flame resistant fibers and the flame resistant cellulosic fibers are dyed. Dyeing and/or shrinkage prevention of these blends is conducted at temperatures below 100Â C. , typically approximately between 70Â C. and 100Â C. Preferably, dye-assistants used in the process are selected from the group comprising N-cyclohexylpyrrolidone, benzyl alcohol, N,N-dibutylformamide, N,N-diethylbenzamide, hexadecyltrimethyl ammonium salt, N,N-dimethylbenzamide, N,N-diethyl-m-toluamide, N-octylpyrrolidone, aryl ether, an approximately 50/50 blend of N,N-dimethylcaprylamide and N,N-dimethylcapramide, and mixtures thereof.

International Classification:

D06P 382

US Classification:

8531, 8925, 442136, 442153, 442164, 442165

Abstract:

The present disclosure relates to flame resistant fabrics that comprise a plurality of inherently flame resistant fibers and a plurality of cellulosic fibers containing a flame retardant compound. In one arrangement, the inherently flame resistant fibers have been dyed and/or shrinkage controlled with a dye-assistant such that the fabric contains a residual amount of a dye-assistant selected from the group consisting of N-cyclohexylpyrrolidone, benzyl alcohol, N,N-dibutylformamide, N,N-diethylbenzamide, hexadecyltrimethyl ammonium salt, N,N-dimethylbenzamide, N,N-diethyl-m-toluamide, N-octylpyrrolidone, aryl ether, an approximately 50/50 blend of N,N-dimethylcaprylamide and N,N-dimethylcapramide, and mixtures thereof.

Appl. No.:

08/206405

Inventors:

Phillip H. Riggins - Greensboro NC, US
John H. Hansen - Greensboro NC, US

Assignee:

Southern Mills, Inc. - Union City GA

International Classification:

D06P 1645

US Classification:

8586, 589602, 589925

Abstract:

Aramid and aramid-blend fabrics are dyed or flame-retardant treated or both dyed and flame-retardant treated using conventional heat dyeing equipment. Amides capable of swelling the aramid fibers at least 1. 5% and preferably having 7 to 14 carbon atoms are used as diffusion-promoting agents for dyes, flame retardant agents or both. Odor-free, flame resistant, colored or colored and highly-flame resistant products result.

Abstract:

The present disclosure relates to patterned, flame resistant fabrics and methods of making them. Generally speaking, the fabrics comprise a plurality of high tenacity, flame resistant fibers, and a plurality of cellulosic fibers containing a flame retardant compound, and at least one color which is printed on the fabric to form the pattern. In a preferred embodiment, the flame resistant fibers are para-aramid fibers and the cellulosic fibers are rayon fibers to yield a strong, flame resistant fabric.

Abstract:

Embodiments of the invention can provide a protective fabric includes a plurality of inherently flame resistant fibers, and at least one ultraviolet-resistant additive incorporated into the inherently flame resistant fibers through a dye process using a carrier, wherein the ultraviolet-resistant additive significantly increases at least one of the strength retention and the colorfastness of the fabric when exposed to ultraviolet radiation.
