Technical Field

The invention relates to the technical field, in particular to a method for recycling textile printing and dyeing residual slurry.

Background

Printing and dyeing, also called dyeing and finishing, is a processing mode and is a general name of pretreatment, dyeing, printing, after finishing, washing and the like; the dyeing and finishing specialty of the department is incorporated into the light chemical engineering specialty; as early as six or seven thousand years ago, in the age of neolithic apparatus, our ancestors were able to dye flax red with hematite powder. The original tribe living in the Nuomu flood area of Qinghai Chaida basin can dye the wool into yellow, red, brown, blue and other colors to weave the wool cloth with color stripes. The staining technique is continuously improved during the week period. The palace manual workshop is provided with a professional chihuili 'dyer' to 'palm dye grass', and manages the dyeing production. The color developed is also increasing. By the han generation, staining techniques reached a fairly high level.

Along with the continuous improvement and the development of dyeing process technology, the color of the dyed textile is also rich continuously, the printing and dyeing residual paste is generated in the current printing and dyeing process, the waste of printing and dyeing fuel is more or less caused, and the discharge of the printing and dyeing residual paste also causes certain pollution, so that the improvement of the existing process is urgently needed, and the existing problem is solved.

Detailed Description

The present invention will be described in further detail with reference to examples.

The general flow of the reactive printing process is as follows: the method comprises the following steps of color paste preparation, printing, steaming, washing, sizing and finished product inspection, wherein for the existing common dyeing color paste, the initial color paste component contains sodium alginate, and as the sodium alginate in the color paste is stored for a long time, the seaweed is easy to deteriorate, and the residual color paste can cause the phenomena of unstable color, light color and dark color. In addition, the reactive dye has hydrolyzability, and is easy to hydrolyze under the action of electrolyte and alkaline agent after being placed for a long time, so that the color is unstable and even the color is changed. The color paste prepared in the way can be stored in the air for 4-5 days, and after 5 days, individual sensitive dyes can have color changes such as active P-6G turquoise blue.

Firstly, the invention changes the problem of hydrolysis of natural paste of sodium alginate in the paste, replaces the natural paste with synthetic paste, synthesizes the paste by combining ATP-30 and RD-02, and has good paste dragging rate and high color yield.

ATP-30 is an adjuvant available from Hensmei and is also sold by Wuxi Reibei textile industries, Inc. The trade name is: LYOPRINT (ready to print) ATP-30 thickener printing aid component is a new pigment printing thickener with optimal rheology on all cloths, including poorly treated or resin treated fabrics. Giving a sharp contour, edge, etc. Bright color, and excellent uniformity especially on poorly pretreated fabrics. Mainly reducing the problem of infiltration.
