Abstract
A process for the treatment of a textile material comprising a) applying evenly a liquor solution (hereinafter referred to as "the liquor") for performing the treatment to the material in such a manner that the dry weight uptake of the solution at the end of this step is no more than 200%; b) then passing the material into a high frequency field of 10-50 MHz for 1 to 120 seconds; and c) optionally maintaining the material at the temperature that the material reaches in the high frequency field for up to 15 minutes (preferably 1-5 minutes).
Claims16
A process for the treatment of textile material comprising the process steps of:
- a) applying a liquor solution to impregnate a textile material in an amount such that the dry weight uptake of the solution is no more than 200%;
- b) subsequently passing the impregnated textile material into a high frequency field of 10-50 MHz for 1 to 120 seconds, and
- c) optionally maintaining the impregnated textile material at the temperature that the textile material reaches in the high frequency field for up to 15 minutes, wherein the liquor is selected from the group consisting of enzymatic bleach solutions, enzymatic desizing solutions, and enzymatic deweighting solutions.
