Patent number: 6547835Abstract: 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° C., typically approximately between 70° C. and 100° C.Type: GrantFiled: July 6, 2000Date of Patent: April 15, 2003Assignee: Southern Mills, Inc.Inventors: Clyde C.

Patent number: 6391065Abstract: A water-dilutable UV light absorber composition and method for improving the lightfastness of dyed textiles is provided. The composition includes from about 5-75% by weight of an ultraviolet light absorbing agent selected from the group consisting of benzotriazole, benzophenone, and phenol substituted triazine; and from about 25-95% by weight of an organic solvent suitable for dissolving the ultraviolet light absorbing agent. The ultraviolet light absorbing agent is applied to the textiles in a concentration sufficient to result in an add-on in the range of between 0.4-4.0% by weight of the textiles when dry.Type: GrantFiled: November 3, 1995Date of Patent: May 21, 2002Assignee: Boehme Filatex, Inc.Inventor: Thomas W.
