Problems solved by technology

[0002] Wool and silk are both protein fibers. The dyes used for printing and the printing process are similar to silk, but the wool fiber has a scale structure and tends to shrink, which will shrink and deform the size of the wool fabric.

Embodiment Construction

[0008] Specific embodiments of the present invention will be further described in detail below.

[0009] A printing process for silk fabrics, the steps are as follows: dye drying vat reduction -> preparation of dye bath -> adjustment of dye bath temperature -> dyeing -> adding ammonium sulfate to maintain the original temperature dyeing for 15 minutes -> washing -> oxidation -> soaping -> Wash -> Dry. In the dyeing step, add 1L of ammonia water to the dyeing solution with warm water at 50°C, 150g of sodium hydrosulfite, and then 10L of colloidal solution (bath ratio 1:10), and finally add dry vat reducing solution for dyeing, and add ammonium sulfate in the later stage of dyeing to reduce The pH of the dyebath is brought to 8.5.

Abstract

The invention relates to a wool dip-dyeing technology. The wool dip-dyeing technology comprises the following steps: vatting reducing dye, preparing a dye bath, adjusting the temperature of the dye bath, dyeing, adding ammonium sulfate to dye for 10-15 minutes under the condition that the original temperature is unchanged, water washing, oxidizing, soap boiling, water washing, and drying. The dyeing step comprises the following processes: firstly, adding 1L of ammonium hydroxide with warm water of 50 DEG C, and 150g of sodium hydrosulfite in a dye liquid; secondly, adding 10L of colloidal solution (a bath ratio of 1:10); thirdly, adding a vat-reduced liquid to perform dyeing, and in the later period of dyeing, adding ammonium sulfate to lower the pH value of the dye bath to 8.5-9. A wool fabric produced by virtue of the technical steps is high in sizing percentage and neither shrinks nor deform easily.

Description

technical field [0001] The invention relates to a dyeing and weaving process, in particular to a wool dyeing and weaving process. Background technique [0002] Wool and silk are both protein fibers. The dyes and printing process used in printing are similar to silk, but wool fiber has a scale layer structure and tends to shrink, which will shrink and deform the size of wool fabrics. Contents of the invention [0003] In view of the above problems, the applicant has conducted research and improvement, and provides a kind of dip-dyeing process for wool fabric without shrinkage and deformation. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A non-fading paint dyeing process steps are as follows: dye drying tank reduction -> preparation of dye bath -> adjustment of dye bath temperature -> dyeing -> adding ammonium sulfate to maintain the original temperature dyei...
