Problems solved by technology

However, most of the current methods and equipment are high-pressure plasma treatment of nonwovens in a closed environment, which requires relatively high equipment requirements; at the same time, the processing speed is relatively slow. For example, the processing equipment speed of Europlasma in Belgium is only 2.5 m / min.

Embodiment

[0028] In this example, the non-woven three-anti-finishing production line, such as figure 2 As shown, it includes an unwinding device 4 , a low-energy plasma processing device 1 , a reagent evaporation device 2 , a high-energy plasma processing device 3 , and a winding device 6 , which are carried out sequentially. The nonwoven in this example is a 45gsm spunmelt nonwoven with a 36gsm spunbond layer and a 9gsm meltblown layer. In this example, the reagent evaporation equipment 2 is a vacuum evaporation equipment, which is used to evaporate the fluorine-containing reagent into a gaseous state. In this example, the used fluorine-containing reagent is 2-acrylic acid-pentafluoroethyl ester, and other optional fluorine-containing reagents are also Including 2-propenoic acid-2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluorooctyl, 2-propenoic acid-2-methyl- 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Pentadecafluorooctyl, 2-Acrylic acid-2-methyl-pentafluorophenyl, 2,3,4,5,6-Pentafluorostyrene, 2,2...

Abstract

The invention relates to a method for carrying out three-resistance finishing treatment on non-woven fabrics, a production line, and an application of the method. The method comprises the following steps of: carrying out low-energy plasma treatment on the surfaces of the non-woven fabrics before carrying out grafting treatment on the surfaces of the non-woven fabrics by using a fluorine-containing reagent; and then carrying out high-energy plasma treatment after the grafting treatment by using the fluorine-containing reagent. According to the method, the adoption of the low-energy plasma treatment can be used for effectively eliminating pollution, and also can form free groups and ion structures on the surfaces of the non-woven fabrics, so as to promote grafting reaction between the fluorine-containing reagent deposited on the surfaces of the non-woven fabrics and the surfaces of the non-woven fabrics, and improve the treatment quality of the fluorine-containing reagent; finally the adoption of the high-energy plasma treatment can promote the grafting reaction, further improve the treatment quality of the fluorine-containing reagent, and improve the three-resistance finishing speed of the non-woven fabrics, wherein the finishing speed can reach 10m / min, which is far beyond the existing finishing speed of 2.5m / min, so that the production efficiency is improved.

Description

technical field [0001] The present application relates to the field of subsequent processing methods of non-woven fabrics, in particular to a method of performing three-resistant finishing on non-woven fabrics, a production line for three-resistant finishing of non-woven fabrics and the application of the production line. Background technique [0002] The three-antibody finishing of non-woven fabrics is the finishing of non-woven fabrics with anti-serum, anti-alcohol, and anti-oil agents. The traditional method is to add fluorine-containing reagents to the surface of non-woven fabrics by saturated impregnation to form a polymer film layer. In order to achieve the effect of anti-serum, anti-alcohol, anti-oil agent. However, the traditional finishing method is slow, which does not match the current high-speed production line; the production efficiency is low; after saturated impregnation, the non-woven fabric needs to go through a long period of drying treatment, which require...
