  • Patent number: 7659217
    Abstract: 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.

  • Publication number: 20050031878
    Abstract: An adhesion promoter comprising a pentaerythritol ester of rosin or polymerized rosin incorporated in a functionalized ethylene copolymer, such as ethylene methylacrylate, is described herein. The adhesion promoter is used for thermal bonding the surfaces of two dissimilar substrates, such as aluminum, paper and film. The adhesion promoter can be used at a lower bonding temperature and enhances peel resistance.

  • Patent number: 5969026
    Abstract: Wettable fibers or filaments are prepared from a composition having a polymer which has a wetting agent incorporated therein. The polymer is selected from the group consisting of olefin polymers, polyesters and polyamides. The wetting agent consists essentially of a glyceride selected from the group consisting of a mono-glyceride, a combination of mono-glycerides and a mixed glyceride having a mono glyceride content of at least 85 percent by weight. The fatty ester group or groups in the glyceride each have from about 12 to about 22 carbon atoms. The olefin polymer is preferably polypropylene, LLDPE, LDPE and HDPE, more preferably polypropylene. The polyamide is preferably a nylon 6 and nylon 6,6. The polyester is preferably a polyethylene terephthalate and a polybutylene terephthalate.
