Embodiment 1

[0020] Including the following steps:

[0021] 1) Mixing additives: Put 2 / 3 of the required amount of water into the additive bucket, add XY-DY with 20g / L of hydrophilic softener (hydrophilic softener can be replaced by color fixing agent or cooling processing agent), Stir well, and finally add the remaining water, while adjusting the pH value of the solution to 5.0;

[0022] 2) One-dipping and one-pressing process: The polyester finished knitted fabric that needs to be repaired is dipped and pressed once in the shaping device with the auxiliary agent prepared in the above step 1), and the liquid pressure rate is 70%;

[0023] 3) Shaping: Put the finished polyester knitted fabric after dipping and pressing into a padding machine for shaping to obtain the final product. The shaping temperature in step 3) is 150°C, the shaping speed is 25 m / min, and the wind speed is 60%. -80%, the setting time is 50S-60S, and the rolling pressure is 3.5 kg.

[0024] Such as figure 1 As shown...

Abstract

The invention discloses a finishing method for restoring color light of a finished polyester knitted fabric. The finishing method comprises the following steps of (1) preparation of additive: adding 2 / 3 of water of demanded quantity into an additive bucket, adding 20g / L of hydrophilic softener (XY-DY), uniformly stirring, adding remained water, and adjusting the PH (potential of hydrogen) value of the solution; (2) one-impregnating and one-pressing technology: performing one-impregnating and one-pressing treatment on the finished polyester knitted fabric requiring color light restoration in a shaping device with the additive prepared in step (1); (3) shaping: adding the finished polyester knitted fabric after one-impregnating and one-pressing treatment into a padder, and shaping, so as to obtain the finished product. The finishing method has the advantages that by operating the simple and convenient one-impregnating and one-pressing technology, and adding the particular additive, the fabric with color deflection in production is restored; the production cost is reduced, and the production time is shortened.

Description

technical field [0001] The invention belongs to the field of textile fabrics, in particular to a finishing method for repairing the shade of polyester finished knitted fabrics. Background technique [0002] Whether the dyeing can be successfully achieved once is affected by many factors such as the quality of the gray fabric, pretreatment, dyeing, and finishing. Regardless of technical reasons or operational problems, it is inevitable to produce some products with substandard quality, such as darker shades, lighter shades, or inconsistent shades. If there is a problem with the color light, it is often repaired in the dyeing tank, which will not only affect the cloth effect of the product, but also greatly increase the cost. Contents of the invention [0003] The object of the present invention is also to provide a method of impregnating and pressing by the one-dipping-pressing method which is easy to operate, adding a specific auxiliary agent, repairing the color cast fab...
