Embodiment 1

[0051] A water-saving pretreatment process for polyester woven fabrics, with a grammage of 150g / m 2 The PET gray cloth is used as raw material, refer to figure 1 , which includes the following steps:

[0052] Step 1. After the gray cloth is unrolled, it runs in the state of open-width rotation, successively passes between the water spray pipe and the air spray pipe arranged opposite to each other in the horizontal direction, and sprays water mist and air on the surface of the gray cloth sequentially through the water spray pipe and the air spray pipe, so that Dust and other sundries on the surface of the gray cloth are washed away and the gray cloth is moistened at the same time. The pressure of the pipe network to control spraying water mist and air is 2MPa.

[0053] Step 2: After the gray cloth is treated in Step 1, it passes between the two pre-treatment agent spray pipes. Spray the pretreatment agent on the surface of the gray cloth through the pretreatment agent spray ...

Embodiment 2

[0065] A water-saving pretreatment process for polyester woven fabrics, with a grammage of 160g / m 2 The PBT gray cloth is used as raw material, refer to figure 1 , which includes the following steps:

[0066] Step 1. After the gray cloth is unrolled, it runs in the state of open-width rotation, successively passes between the water spray pipe and the air spray pipe arranged opposite to each other in the horizontal direction, and sprays water mist and air on the surface of the gray cloth sequentially through the water spray pipe and the air spray pipe, so that Dust and other sundries on the surface of the gray cloth are washed away and the gray cloth is moistened at the same time. The pressure of the pipe network to control spraying water mist and air is 1MPa.

[0067] Step 2: After the gray cloth is treated in Step 1, it passes between the two pre-treatment agent spray pipes. Spray the pretreatment agent on the surface of the gray cloth through the pretreatment agent spray ...

Embodiment 3

[0079] A water-saving pretreatment process for polyester woven fabrics, with a grammage of 180g / m 2 PET / PBT blended gray fabric (84:16) as raw material, refer to figure 1 , which includes the following steps:

[0080] Step 1. After the gray cloth is unrolled, it runs in the state of open-width rotation, successively passes between the water spray pipe and the air spray pipe arranged opposite to each other in the horizontal direction, and sprays water mist and air on the surface of the gray cloth sequentially through the water spray pipe and the air spray pipe, so that Dust and other sundries on the surface of the gray cloth are washed away and the gray cloth is moistened at the same time. The pressure of the pipe network to control spraying water mist and air is 3MPa.

[0081] Step 2: After the gray cloth is treated in Step 1, it passes between the two pre-treatment agent spray pipes. Spray the pretreatment agent on the gray cloth surface through the pretreatment agent spra...

Abstract

The invention discloses a polyester woven fabric water-saving pretreatment process and its application, which belongs to the technical field of textile processing pretreatment. The main points of the technical scheme include the following steps: 1. Spray water mist and air to remove dust and moisten; 2. Spray the pre-treatment agent of special formulation; the spray amount of the pre-treatment agent accounts for 10-30wt% of the gray cloth, including sodium hydroxide 16-20wt%, organic alkali 1-2wt%, penetrant 1‑2wt%, accelerator 0.5‑1.0wt%, water retaining agent 0.5‑1.0wt%, and the rest of water; 3. Roll up and cover the surface with plastic film, and place it in an environment of 10‑30°C for 24‑48h, During this period, the gray cloth roll is kept rotating at a speed of 0.5-5rpm; 4. After unrolling, steam it for 25-45min at 110-130°C and a humidity of 85-95%; 5. Wash and dry in open width. The pretreatment process of the present invention has the advantages of short process flow and greatly reduced pretreatment water consumption and energy consumption, and is suitable for pretreatment processing of various polyester bleached cloths, plain white cloths, dyed cloths and printed cloths.

Description

technical field [0001] The invention relates to the technical field of textile processing pretreatment, more specifically, it relates to a polyester woven fabric water-saving pretreatment process and its application. Background technique [0002] The printing and dyeing industry is an important part of the textile industry. It is an important link in the deep processing of products in the textile and clothing production chain, improving quality, function and value, and an important technical support for industries such as high value-added clothing, home textiles and high-tech textiles. [0003] Printing and dyeing is a chemical and physical process with water as the medium, including multiple processes such as desizing, scouring, bleaching, mercerizing, dyeing, printing and finishing. During the processing process, due to the addition and discharge of chemicals such as dyes and auxiliaries, textiles undergo continuous alternating dry and wet treatments, making the printing a...
