Problems solved by technology

[0004] At present, in addition to atmospheric pressure dielectric barrier discharge plasma (DBD) and atmospheric pressure glow discharge plasma (APGD), atmospheric pressure jet plasma (APPJ) has gradually become a research hotspot in the field of textiles. For example, Hatice Aylin Karahan and Alberto Ceria et al. APPJ is used for anti-felting finishing of wool fabrics, but few reports can make wool knitted fabrics reach the "machine washable" standard
Secondly, because wool fiber has a high moisture regain and needs to be wet-processed such as scouring, the effect of moisture or environmental humidity on wool fabrics treated by APPJ is very important, but there is no research on this aspect so far

Embodiment 1

[0020] Plasma treatment of dry wool textiles.

[0021] After the wool textiles were conditioned for 48 hours at a temperature of 20±1 °C and a humidity of 10±1%, the samples were evenly spread on the operating table, and plasma was applied to both the front and back sides under normal pressure. Treatment, 1 treatment per side. Adjust the parameters of the plasma generator: the discharge power is 150 W, the processing speed is 12.0 mm / s, the height from the sample to the outlet is 5.0 mm, He / O 2 Controlled at 30.0 / 0.4 L / min.

Embodiment 2

[0023] Plasma treatment of wet wool textiles.

[0024] After the woolen textiles were sealed and placed for 48 h at a temperature of 20±1 °C and a humidity of 98±1 % for balanced humidity adjustment, the samples were evenly spread on the operating table, and both the front and back sides were tested under normal pressure. Plasma treatment, 1 treatment per side. Adjust the parameters of the plasma generator: the discharge power is 150 W, the processing speed is 12.0 mm / s, the height from the sample to the outlet is 5.0 mm, He / O 2 Controlled at 30.0 / 0.4 L / min.

Embodiment 3

[0026] Plasma treatment of water-soaked wool textiles.

[0027] Soak the wool textile in distilled water, place it in a sealed place at a temperature of 20±1°C for 48 hours to balance the humidity, spread the sample evenly on the operating table, and conduct plasma on both the front and back sides under normal pressure Treatment, 1 treatment per side. Adjust the parameters of the plasma generator: the discharge power is 150 W, the processing speed is 12.0 mm / s, the height from the sample to the outlet is 5.0 mm, He / O 2 Controlled at 30.0 / 0.4 L / min.

Abstract

The invention discloses an atmospheric pressure plasma jet wet-method shrink-proofing method for a wool knitted fabric, and belongs to novel wool shrink-proofing finishing methods. According to the atmospheric pressure plasma jet wet-method shrink-proofing method, the surface of wet wool is modified by using atmospheric pressure plasma jet (APPJ). On the premise that the mechanical property and the dyeing fastness of wool are generally not affected, etching of APPJ to the scale layer of wool can be enhanced by using the wet-method treatment process, the static and dynamic orientation friction effect of the scale of wool can be reduced, the wool knitted fabric can meet the machine-washable standard that the shrink-proofing rate is less than 8.0%, and the apparent dyeing depth of the wool knitted fabric, by reactive dyes can be improved. The APPJ wet-method treatment disclosed by the invention has the characteristics of low environment requirements, simplicity and convenience in processing and treatment, small fiber damage and the like, the treatment effect of APPJ on wool fabrics with high moisture regain can be improved, limit on wet processing on wool in practical application can be reduced, and thus convenience can be provided for industrial popularization and application of the atmospheric pressure plasma jet wet-method shrink-proofing method.

Description

technical field [0001] The invention relates to surface modification of wet wool by using normal-pressure jet plasma, and belongs to the technical field of wool anti-felting finishing. Background technique [0002] The directional friction effect (DFE) of the scale layer on the surface of wool fibers will cause felting of wool textiles during washing, which will seriously affect their appearance, feel, easy-care performance and wearing performance. Therefore, the focus of reducing the felting of wool textiles is to reduce the DFE of wool. At present, chemical or physical methods are mainly used for finishing. The typical chemical method is Hercosite resin finishing with chloride, which has a remarkable anti-felting effect, but the process is cumbersome, and the adsorbable organic halides (AOX) produced will endanger health and the environment. [0003] In recent years, the application of physical methods represented by low-temperature plasma technology in the textile field ...
