Patent attributes
The present invention is directed to the design and manufacturing of a field durable, repeatedly launderable and permanently fire resistant, comfortable and economical FR nonwoven composite fabric based garment, which meets the stringent requirements of military combat uniform clothing. The nonwoven based garment is designed to replace the traditional woven textile fabric used in the military today. The novel garment of the current invention is constructed using a unique spunlaced or hydroentangled FR nonwoven composite fabric that exhibits mechanical, physical, durability and comfort characteristics similar to or better than that of the current woven military uniform fabric. In particular, the present invention contemplates the nonwoven composite fabric used to make the garment is prepared by combining at least two separate nonwoven webs forming the inside and outside layers of the garment. An optional rip-stop element such as a loosely knitted fabric may be sandwiched between the two nonwoven webs to improve the dimensional stability of the entire garment. Hydroentangling process combines the individual nonwoven webs to form a coherent base nonwoven composite fabric before dyeing and printing which is then made fire resistant by application of a phosphate ester chemical in an ammonia-cure process to form the FR nonwoven composite fabric of the garment.
