Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0022] see figure 1 , figure 1 It is a flow chart of the method for desizing cotton gray cloth provided by the present invention, and the method flow includes a plasma treatment method 101, a singeing method 102, a semi-scouring method (or omitting scouring) 103 and a bleaching method 104.

[0023] Plasma treatment method 101 is to use atmospheric pressure plasma technology to treat cotton gray cloth, which can effectively etch and decompose the slurry on the cotton gray cloth, cut off its molecular chain, and greatly reduce its adhesion to cotton , and can activate the surface of the cotton cloth, so that the cottonseed hulls, pectin, grease, wax and other parts are oxidized, and the rest are easy to remove.

Abstract

The invention discloses a method for desizing cotton grey cloth, which is a novel treatment method comprising the following steps: first using plasma equipment blocked by a medium to treat the cotton grey cloth, singeing, boiling-off with low chemical concentration in a short time and finally bleaching, i.e. plasma->singeing->half-boiling-off (or omitting boiling-off)-bleaching; and the capillary effect, the breaking strength, the white content and the like of the semi-finished cloth after treatment are close to those of the semi-finished cloth treated by conventional production methods, and the alkali boiling-off concentration and steaming time thereof are one third lower than those of the semi-finished cloth treated by the conventional production methods. The method can be used for the pre-treatment of the cotton grey cloth, and achieves the purposes of saving energy and reducing emission.

Description

technical field [0001] The invention relates to the technical field of cotton gray cloth desizing treatment, in particular to a novel method for desizing cotton gray cloth by adding plasma. Background technique [0002] Cotton cloth must be desized and scoured before dyeing, printing and finishing. The traditional method is mainly to use strong alkali for high-temperature steaming, and also to wash in hot and cold water, which consumes water and energy and produces a lot of waste water. polluted environment. [0003] Using atmospheric pressure plasma technology to treat cotton gray cloth can not only effectively etch and decompose the slurry on the cotton gray cloth, cut off its molecular chain, greatly reduce its adhesion to cotton, but also activate the surface of cotton cloth , so that the cottonseed hulls, pectin, oil, wax, etc. are partially oxidized, and the rest are easy to remove. After plasma treatment, the use of a large amount of chemical raw materials in tradit...
