Title:
TEXTILE DESIZING PRETREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2016/058257
Kind Code:
A1
Abstract:
Disclosed is a textile desizing pretreatment method, belonging to the technical field of textile dyeing and finishing, and designed in order to solve the problems of conventional desizing processes, such as high water consumption and large wastewater discharge. The method comprises the following steps: A. a surfactant is dissolved in a mixed solution of ethanol and water; B. a desizing enzyme is added to the mixed solution, which is stirred until the system is clarified to obtain a desizing working solution; C. the desizing working solution is placed into a supercritical carbon dioxide fluid handling system; D. the desizing working solution uses the supercritical carbon dioxide medium to form a microemulsion; desizing pretreatment is performed on the textile under the conditions of a temperature of 30°C to 95°C, a pressure of 6 MPa to 30 MPa, and a total desizing time of 0.5 h to 24.0 h. The present invention has a simple process and achieves textile desizing pretreatment; by means of controlling reaction parameters such as temperature, pressure, and treatment time, the desizing efficiency of the enzyme in the supercritical carbon dioxide medium is improved, and the invention is energy-saving and environmentally friendly.
