Embodiment Construction

[0013] A kind of dye liquor of silk fabric of the present invention, formula is as follows:

[0014] Reactive dye 3% (o.w.f);

[0015] Yuanming powder 30g / L

[0016] Soda ash 20g / L;

[0017] Bath ratio 1:20.

[0018] Process: Prepare the dye solution according to the prescription, put it in the dye vat, adjust the ph value of the dye solution to 4-5 - raise the temperature to 40 degrees - put it into the fabric - keep it warm for 15 minutes - put in soda ash - keep it warm for 10 minutes - 3 degree / min to 60-70 degrees, keep warm for 15 minutes—add sodium carbonate—keep warm for 30 minutes—wash with water.

Abstract

The invention discloses a dye liquor for a silk fabric and a dyeing process. The dye liquor comprises the following ingredients of 3 percent o.w.f (on weight the fabric) of reactive dye, 30 g / L of anhydrous sodium sulphate and 20 g / L of sodium carbonate; and the bath ratio is 1:20. The dyeing process comprises the following steps of: putting the dye liquor in a dye jar; adjusting the pH value of the dye liquor to 4-5; raising the temperature to 40 DEG C; putting the fabric in the dye liquor and preserving the temperature for 15 minutes; putting in the sodium carbonate and preserving the temperature for 10 minutes; raising the temperature to 60-70 DEG C in the rate of 3 DEG C / min, and preserving temperature for 15 minutes; adding sodium carbonate and preserving temperature for 30 minutes; and finally washing. The dyeing process is simplified, the production practice is shortened, and the production efficiency is increased. The aim of producing products with high union dyeing property can be well realized through the dyeing process.

Description

technical field [0001] The invention relates to a dye liquor and a dyeing process for silk fabrics. Background technique [0002] In order to make the three components of mulberry silk, cotton and hemp obtain good color homogeneity during the dyeing process, reactive dyes are used to dye silk / hemp and cotton products in one bath. But silk, hemp cotton fabric adopts the same color problem in the dyeing of reactive dyestuff to be difficult to solve. Contents of the invention [0003] The object of the present invention is to provide a dyeing solution and a dyeing process for silk fabrics aiming at the defects in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A kind of dye liquor of silk fabric of the present invention comprises following component: [0006] Reactive dye 3% (o.w.f); [0007] Yuanming powder 30g / L; [0008] Soda ash 20g / L; [0009] The bath ratio is 1:20. [0010] A ...
