  • Patent number: 5861044
    Abstract: 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.
