Problems solved by technology

[0002] After the warp yarn is sized, without any treatment, the size components will remain on the fabric through the weaving process, and will be taken to the next process with the fabric. Therefore, the warp yarn needs to be desized after the warp yarn is sized so that At this time, the slurry is left in the waste liquid after being washed with water, and the burden of waste liquid treatment is heavy. If some slurry with poor biodegradability is discharged into the external environment, the ecological impact will be caused Larger and increases the cost of the sizing process in the textile process

Abstract

The invention discloses a textile sizing agent recycling and reusing method. The textile sizing agent recycling and reusing method comprises the following steps that warp yarn obtained after sizing ofraw stock is desized; the desized warp yarn is washed with water, a solution obtained after water washing and a solution obtained in the desizing process are collected, and finally, desizing liquid is obtained; the desizing liquid obtained in the previous step is concentrated, so that the solid content of the concentrated desizing liquid is T, wherein T is equal to or larger than 6% or equal to or smaller than 6.5%; a mixture of acrylamide and water is added into the concentrated desizing liquid for adjustment, regenerated sizing fluid is obtained, and the warp yarn is sized through a single-yarn sizing machine by using the regenerated sizing fluid. By means of the method, textile sizing agent recycling and reusing can be achieved, textile sizing agent recycling is facilitated, the cost of a sizing process in a textile manufacturing process is reduced, and the pollution to the environment is further reduced.

Description

technical field [0001] The invention relates to the technical field of textile slurry treatment, in particular to a method for recycling textile slurry. Background technique [0002] After the warp yarn is sized, without any treatment, the size components will remain on the fabric through the weaving process, and will be taken to the next process with the fabric. Therefore, the warp yarn needs to be desized after the warp yarn is sized so that At this time, the slurry is left in the waste liquid after being washed with water, and the burden of waste liquid treatment is heavy. If some slurry with poor biodegradability is discharged into the external environment, the ecological impact will be caused Larger, and increased the cost of the sizing process in the textile process. [0003] Therefore, if the waste liquid after desizing can be recycled, processed and reused, not only the cost of the warp sizing process in the weaving process can be saved, but also the pollution to th...
