Problems solved by technology

Its shortcoming is: after the fabric is immersed in the finishing solution twice, the fabric immersed in the water-repellent finishing solution first will absorb a large amount of water-repellent finishing agent, resulting in a decrease in the concentration of the water-repellent finishing solution, so that the repellent adsorbed on the fabric appears in the direction of fabric travel. The decrease in the concentration of the water finishing solution eventually leads to fluctuations in the water repellent finishing effect in the length direction of the piece

Embodiment 1

[0014] The pure cotton fabric is pulled to the cloth storage tank at 5 m / min, and then pulled to the bottom of the electromagnet by the active traction guide roller group in the water-repellent finishing process. , the magnetic force of the electromagnet is 784N, the weight of the dipping plate is 60kg, and the depth of the finishing liquid tank is 0.4 meters. The generated magnetic force lifts the iron dipping plate and holds the fabric between the electromagnet and the dipping plate. The clamping time is 0.5 seconds, the water-repellent finishing agent is FG-910 from Shenzhen Jieershuang High-tech Co., Ltd., the concentration of the water-repellent finishing solution is 60g / L, the electromagnet is powered off, and stops working. The traction guide roller is powered on and starts to work, and the fabric runs for the next stage of fabric finishing. The water-repellent effect of the reverse side of the fabric is shown in Table 1.

Embodiment 2

[0016] The pure cotton fabric is pulled to the cloth storage tank at 25 m / min, and then pulled to the bottom of the electromagnet by the active pulling guide roller group in the water-repellent finishing process. , the magnetic force of the electromagnet is 882N, the weight of the dipping plate is 65kg, and the depth of the finishing liquid tank is 0.5 meters. The generated magnetic force will lift the iron dipping plate and hold the fabric between the electromagnet and the dipping plate. The clamping time is 0.75 seconds, the water-repellent finishing agent is FG-910 from Shenzhen Jieershuang High-tech Co., Ltd., the concentration of the water-repellent finishing solution is 60g / L, the electromagnet is powered off, and stops working. The traction guide roller is powered on and starts to work, and the fabric runs for the next stage of fabric finishing. The water-repellent effect of the reverse side of the fabric is shown in Table 1.

Embodiment 3

[0018] The pure cotton fabric is pulled to the cloth storage tank at 45 m / min, and then pulled to the bottom of the electromagnet by the active pulling guide roller group in the water-repellent finishing process. , the magnetic force of the electromagnet is 980N, the weight of the dipping plate is 70kg, and the depth of the finishing liquid tank is 0.6 meters. The generated magnetic force will lift the iron dipping plate, and hold the fabric between the electromagnet and the dipping plate. The clamping time is 1 second, the water-repellent finishing agent is FG-910 from Shenzhen Jieershuang High-Tech Co., Ltd., the concentration of the water-repellent finishing solution is 60g / L, the electromagnet is powered off, and stops working. The traction guide roller is powered on and starts to work, and the fabric runs for the next stage of fabric finishing. The water-repellent effect of the reverse side of the fabric is shown in Table 1.

Abstract

The invention relates to an adsorption-type water repellent finish method for fabric by lifting a liquid-dipping board under magnetic force, belonging to the technical field of weaving. A finish liquid tank is hollow in shape. The iron liquid-dipping board is movably installed in the finish liquid tank. An electromagnet is fixedly arranged above the finish liquid tank. The electromagnet corresponds to the iron liquid-dipping board. The electromagnet is the same as the iron liquid-dipping board in surface area. Magnetic force of the electromagnet is in direct proportion to the weight of the liquid-dipping board and the depth of the finish liquid tank. The electromagnet and an active guide roller set are connected to a stroke controller. The finish method enables the fabric not to be in direct contact with water-repellent finish liquid. The concentration of the water-repellent finish liquid does not change because the fabric excessively adsorbs a water-repellent finish agent in the water-repellent finish liquid. Differences caused by changing concentration of the water-repellent finish liquid do not occur in the water-repellent finish effect of the fabric. Accordingly, the concentration of the water-repellent finish liquid does not change during water-repellent arrangement by adoption of the technical scheme. Therefore, consistency of the water-repellent effect of the fabric is ensured.

Description

technical field [0001] The invention relates to a fabric magnetic lifting staining liquid absorption type water-repellent finishing method, which belongs to the technical field of textiles. Background technique [0002] Water-repellent finishing of fabrics is a common technique for textile finishing. Fabrics after water-repellent finishing have good water repellency, thereby improving the wearability of fabrics and expanding the scope of use of fabrics. The common process of water repellent finishing is padding finishing process. Chinese public publication "Journal of Xi'an Polytechnic University", published in 2016, Volume 30, Issue 01, the title of the article is the application of fluorosilicone soap-free water-repellent agent in the water-repellent finishing of cotton fabrics. Soap-free water-repellent agent is used for water-repellent finishing of cotton fabrics. The finishing process is two dipping and two-rolling. After the fabrics dipped and rolled with water-repell...
