Patterned, flame resistant fabrics and method for making same

a technology of flame-resistant fabrics and patterned fabrics, which is applied in the field of patterned, flame-resistant fabrics, can solve the problems of inability to meet the tensile strength and tear strength of such a fabric would likely fall far short of the requirements of mil-c-44436, and the use of such fibers is generally not considered viable for bdu construction

Problems solved by technology

Although personnel could be issued BDUs constructed primarily of meta-aramid fibers to obtain the desired flame resistance, the costs of providing each person with such a garment would be extremely large.
In addition, the tensile and tear strengths of such a fabric would likely fall far short of the requirements of MIL-C-44436(GL) and MIL-C-44031D.
Although there are known fibers that have desirable flame resistance properties as well as high tensile and tear strengths, use of such fibers is generally not considered viable for BDU construction because it is difficult to form durable patterns on many of these fibers.

Embodiment Construction

[0008]The present disclosure relates to flame resistant fabrics that are well suited for use to in the construction of military BDUs. Although the discussion that follows focuses on BDUs and U.S. military specifications MIL-C-44436(GL) and MIL-C44031D, it is to be understood that the fabrics described herein could be used in various other applications, if desired. In addition, it is to be understood that, for purposes of the present disclosure, fibers identified by a named material followed by the term “fiber” are not limited to fibers composed exclusively of the named material.

[0009]As identified above, MIL-C-44436(GL) and MIL-C-44031D contain many physical property requirements for materials used to construct BDUs. In view of the aforementioned difficulties in designing a flame resistant BDU, of particular concern is fabric durability as defined by tensile (i.e. breaking) strength and tear strength. Table I provides the class 1 requirements set by MIL-C-44436(GL), published Jul. 1...

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.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 09 / 062,805, filed Apr. 20, 1998, now U.S. Pat. No. 6,132,476, and further claims the benefit of the filing date of U.S. Provisional Patent Application Ser. No. 60 / 149,792, filed Aug. 19, 1999. Both of these applications are hereby incorporated by reference into the present disclosure.FIELD OF THE INVENTION[0002]The present invention relates to patterned, flame resistant fabrics. More particularly, the present invention relates to flame resistant fabrics well suited for use in the construction of camouflage battle dress uniforms. In addition, the invention relates to methods for making such fabrics.BACKGROUND OF THE INVENTION[0003]Presently, U.S. infantry troops are issued camouflage patterned garments known as battle dress uniforms (BDUs). BDUs are used both in battle and during the execution of other tasks associated with military service. The BDUs in current u...
