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.

Patterned, flame resistant fabrics and method for making same

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.

Ultraviolet-resistant fabrics and methods for making them

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.

Dye diffusion promoting agents for aramids

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 100&deg; C., typically approximately between 70&deg; C. and 100&deg; 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.

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.

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.

Aramid and aramid-blend fabrics are dyed or flame-retardant treated or both dyed and flame-retardant treated using conventional heat dyeing equipment. Aliphatic amides capable of swelling the aramid fibers at least 1.5% and having 7 to 14 carbon atoms are used as diffusion-promoting agents for dyes, flame retardent agents or both. Odor-free, flame resistant, colored or colored and highly-flame resistant products result.

Aramid fabrics treated with N-cyclohexyl-2-pyrrolidone prior to or simultaneously with aqueous print pastes promote fabric printability and produces good coloration. Saturated steam or superheated steam at a temperature of at least 100.degree. C. permeates and fixes the dye inside of the aramid fibers. Print pastes containing N-cyclohexyl-2-pyrrolidone, dye and thickener are also described.

Process for dyeing or printing/flame retarding aramids

Poly(m-phenyleneisophthalamide) fabrics are printed and optionally flame retarded in a two-step process in which the dye diffusion promoting agent N-octyl-2-pyrrolidone optionally with a flame retardant is applied following by printing and print fixation.

Process for dyeing or printing/flame retarding aramids with

Durable press finishes are applied to cellulosic materials such as cotton by cross-linking a polycarboxylic acid within the cellulosic fibers using a cyanamide compound cross-linker devoid of phosphorus. Wrinkle-resistant, durable cellulosic materials free from formaldehyde odor result.

Formaldehyde-free textile finish

Aramid and aramid-blend fabrics are dyed or flame-retardant treated or both dyed and flame-retardant treated using conventional heat dyeing equipment. Octylpyrrolidones, tributyl phosphine oxide and mixtures of N-cyclohexyl-2-pyrrolidone with available dye carriers 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.
