Embodiment 1

[0039] Embodiment 1: the dyeing method of polyester woven fabric exempting from retraining, comprises the following steps:

[0040] S1: 500kg of cationic pongee open-width desizing, directly into the vat, and add water, the bath ratio is 1:10;

[0041] S2: Slowly add 5kg of non-retraining auxiliary agent into the machine cylinder, and run for 10 minutes after the feeding is completed, so that the non-retraining auxiliary agent is fully diluted, fully neutralizes the residual alkali, and disperses impurities such as cloth surface slurry and oligomers , the retraining-free auxiliary agent is a 1:1 (mass ratio) compound of polyacrylic acid series multi-polymer and polyester surfactant.

[0042] S3: Add 5kg of Disperse Brilliant Blue 2BLM warm water chemical into the vat for high temperature and high pressure dyeing. The dyeing heating curve is as follows figure 1 shown.

[0043] S4: Add 2g / L acid reduction cleaning agent and keep warm for 15-20min to remove floating color on th...

Embodiment 2

[0045] Embodiment 2: the dyeing method of polyester woven fabric exempting from retraining, comprises the following steps:

[0046] S1: After desizing 600kg polyester taffeta open width, it is directly put into the vat, and water is added, the liquor ratio is 1:8.

[0047] S2: Slowly add 6kg of non-retraining auxiliary agent into the machine cylinder, and run for 10 minutes after the feeding is completed, so that the non-retraining auxiliary agent is fully diluted, fully neutralizes the residual alkali, and disperses impurities such as cloth surface slurry and oligomers. The retraining-free auxiliary agent is a 3:1 (mass ratio) compound of polyacrylic acid series multi-polymer and polyester surfactant.

[0048] S3: Add 8kg of disperse Cuilan S-GL warm water chemical into the vat for high temperature and high pressure dyeing. The dyeing temperature rise curve is as follows figure 1 .

[0049] S4: Add 3g / L acid reduction cleaning agent, keep warm for 15-20min, and remove floatin...

Embodiment 3

[0051] Embodiment 3: the dyeing method of polyester woven fabric free from retraining, comprises the following steps:

[0052] S1: After 500kg of mycetin is desized in the open width, put it directly into the vat, and add water, the liquor ratio is 1:10.

[0053] S2: Slowly add 8kg of non-retraining auxiliary agent into the machine cylinder, and run for 10 minutes after the feeding is completed, so that the non-retraining auxiliary agent is fully diluted, fully neutralizes the residual alkali, and disperses impurities such as cloth surface slurry and oligomers. The retraining-free auxiliary agent is a 2:1 (mass ratio) compound of polyacrylic acid series multi-polymer and polyester surfactant.

[0054] S3: Add 5kg of Sancuilan S-GL warm water chemical into the vat for high temperature and high pressure dyeing. The dyeing temperature rise curve is as follows: figure 1 .

[0055] S4: Add 3g / L acid reduction cleaning agent, keep warm for 15-20min, and remove floating color on th...

Abstract

The invention discloses a re-scouring-free dyeing method for a polyester woven fabric. The method comprises the following steps of a, directly feeding a de-sized fabric into a vat, and adding a proper amount of water; b, slowly adding a re-refining-free auxiliary agent into a machine cylinder, and operating for a period of time; c, filtering the prepared dye liquor into the vat, and carrying out high-temperature and high-pressure dyeing; d, performing reduction cleaning; and e, washing with water. The method solves the problem that the open-width de-sized fabric is easy to generate slurry spots, dyeing defects, poor vat quality and the like when being directly dyed in the vat, and can improve the one-time success rate of dyeing in a dyeing factory, shorten the process flow and improve the production efficiency.

Description

technical field [0001] The invention belongs to the field of printing and dyeing of textiles, and relates to a method for dyeing polyester woven fabrics without retraining. Background technique [0002] Polyester woven fabric itself does not contain natural impurities. The fabric mainly contains the size applied in the spinning and weaving process, as well as a small amount of oil stains and dust contaminated during transportation and storage. In order to remove sizing and other impurities on the fabric, polyester woven fabrics are generally treated by cylinder desizing (intermittent) and flat desizing (continuous). The open-width desized fabric maintains good breaking and tearing strength and the fabric feels plump, while the cylinder desizing process takes a long time, consumes high energy, and causes heavy pollution, which does not meet the domestic environmental protection policy and the advocacy of energy conservation and emission reduction. , the traditional cylinder ...
