Problems solved by technology

[0002] The existing woven fabrics are generally dyed by padding dyeing method. Then, the dye solution is placed in the dyeing vat, and then the fabric is placed in the dyeing vat and left to stand for 3 to 5 hours for dyeing, and some even need to stand for 8 hours. Above, the dyeing time is longer and the dyeing efficiency is lower
Moreover, the color dyed by the existing weaving dyeing method is more prone to fading, and the dyeing stability is not ideal
Therefore, the existing fabric dyeing methods have the problems of long dyeing time, low dyeing efficiency and unsatisfactory dyeing stability.

Embodiment 1

[0022] Embodiment one. The good woven fabric dyeing method of dyeing stability, comprises the following steps:

[0023] a. Soak the fabric in the dyeing auxiliaries for 10-15 minutes. During soaking, use a mixer to stir evenly, and use ultrasonic vibration treatment to obtain product A;

[0024] B. Rolling is carried out to product A with rolls, and the excess rate is 40% to 50%, so as to obtain product B;

[0025] c. Place B product in a steam oven for dry steaming treatment, the dry steaming temperature is 120°C-130°C, and the dry steaming time is 5min-8min, to obtain C product;

[0026] d. Use a dye evaporation device to evaporate the dye solution to generate dye vapor, and then pass the dye vapor into the steam furnace to dye product C. When dyeing, use the breathing method to adjust the air pressure in the furnace. The temperature in the furnace is 100 ℃ ~ 110 ℃, the dyeing time is 20min-30min, and product D is obtained;

Abstract

The invention discloses a fabric dyeing method with good dyeing stability. The method comprises steps as follows: fabric is firstly soaked in a dyeing auxiliary, is subjected to stirring and ultrasonic oscillation treatment simultaneously and then is subjected to roll compacting and dry blowing treatment, a dye solution is evaporated into dye steam, the dye steam is introduced to the fabric for dyeing, furthermore, repeated circulating pressurization and negative pressure application are performed during dyeing, dyes are pressed to the fabric for dyeing through pressurization, the dyeing efficiency is improved, part of dyes with poorer dyeing stability are separated out through the negative pressure application, then the fabric is dyed again through pressurization, and the dyeing stability is improved; a color fixing agent is added for fumigation treatment, and steam formed through evaporation of the color fixing agent is used for fumigating the fabric; finally, the fabric is washed and dried, and a finished product is obtained. The fabric dyeing method has the advantages as follows: the dyeing time can be shortened, the dyeing efficiency is improved, and the dyeing stability is good.

technical field [0001] The invention relates to a fabric dyeing method, in particular to a fabric dyeing method with good dyeing stability. Background technique [0002] The existing woven fabrics are generally dyed by padding dyeing method. Then, the dye solution is placed in the dyeing vat, and then the fabric is placed in the dyeing vat and left to stand for 3 to 5 hours for dyeing, and some even need to stand for 8 hours. Above, the dyeing time is longer and the dyeing efficiency is lower. Moreover, the color dyed by the existing weaving dyeing method is more prone to fading, and the dyeing stability is not ideal. Therefore, existing fabric dyeing methods have the problems of longer dyeing time, lower dyeing efficiency and unsatisfactory dyeing stability. Contents of the invention [0003] An object of the present invention is to provide a method for dyeing woven fabric with good dyeing stability. The invention can not only shorten the dyeing time and improve the dy...
