Patent number: 5865933Abstract: An apparatus and method for creation of a textile fabric that has been patterned with a selective application of heat, which provides a carved portion in registry with a color change. The textile fabric includes a blend of fibers of a first polymer having a first color with fibers of a second polymer having fibers of a second color.

Patent number: 5861044Abstract: An apparatus and method for selectively carving textile fabric by selectively applying chemicals containing a liquid repellent either alone or with other chemicals such as dye to a textile fabric and subsequently finishing said fabric. The textile fabric is then rewetted by the application of liquid. The printed areas containing liquid repellant remain dry and the areas without liquid repellent are selectively wetted out. The textile fabric is then subjected to pressurized heated gas which selectively carves the dry areas printed with liquid repellent leaving the wetted areas protected and uncarved. As an alternative embodiment, the yarns that make up a textile fabric can be individually treated with a liquid repellent prior to being formed into a textile fabric.Type: GrantFiled: December 5, 1996Date of Patent: January 19, 1999Assignee: Milliken Research CorporationInventor: Edward Leland Crenshaw
