Abstract

The invention discloses a one-bath processing method for towel desizing and polishing. In the method, the desizing step and the polishing step of the towel are combined into one, and the desizing and polishing are completed in the same step. In addition, the invention also discloses the application of desizing enzyme and neutral cellulase in the one-bath processing technology of towel desizing and polishing. The present invention optimizes the traditional technological process, combines the desizing process and the polishing process of towels into one, overcomes the inconsistency between the pH value range suitable for the action of acid cellulase and the pH value range required for desizing, and the inconsistency between polishing and polishing. The problem of temperature inconsistency required by the desizing process achieves the purpose of simplifying the process steps, shortening the process time, saving water, energy and reducing costs.

Description

technical field [0001] The invention relates to the application field of biological enzyme preparations, in particular to the application of desizing enzymes and cellulase preparations in the production and processing of towels, and in particular to a one-bath processing method for towel desizing and polishing. Background technique [0002] Too much hairiness in towels (that is, high hair removal rate) has always been an important factor affecting the quality of towels and even causing towel degradation, especially for towels exported to Europe and the United States. Because Europeans and Americans have hard and dense beards and sideburns, towels are more dense during use. It is prone to hair loss. Polishing towels with cellulase can significantly improve the hairiness of towels. The towel surface is clean, the loops are clear and full; in addition, it can effectively improve the color brightness of towels and significantly improve the quality of towels. [0003] The polishi...
