Problems solved by technology

[0005] Aramid fiber is a kind of high-performance fiber, which is widely used in aerospace and military fields due to its heat resistance, flame retardancy, and chemical corrosion resistance. However, the content of polar groups on the surface of the fiber is low, and the terminal carbonyl It is enriched on the surface of the fiber, which affects its infiltration and bonding performance to the resin

Embodiment 1

[0023] As shown in Figure 1, a kind of device that is used for the treatment of excimer ultraviolet light source of textile surface modification, comprises three parts of power system 1, excimer ultraviolet light source treatment room 2 and pressure control system 3, described excimer ultraviolet The light source processing chamber 2 is equipped with an excimer ultraviolet lamp tube 4 and a sample placement platform 5 .

[0024] During use, place the woven twill wool fabric on the sample placement platform of the device provided by the present invention, adjust the distance between the excimer ultraviolet lamp tube and the fabric to be 0.5cm, adjust the pressure in the excimer ultraviolet light source treatment chamber to be 100KPa, open Power supply, control the irradiation time to 8min. The surface properties and breaking strength of wool fabrics after treatment are shown in Table 1. After irradiation treatment, the scale layer on the wool fiber surface was etched, and the ...

Embodiment 2

[0028] Place the woven plain aramid fabric on the sample placement platform of the device provided by the present invention, adjust the distance between the excimer ultraviolet lamp tube and the fabric to be 1cm, adjust the pressure in the excimer ultraviolet light source treatment chamber to be 80KPa, turn on the power, Control the irradiation time to 5min. The surface properties and breaking strength of the treated aramid fabric are shown in Table 2. After irradiation treatment, the smooth surface of the fiber was etched rough and polar groups were introduced into the surface.

Abstract

The invention relates to a method for processing excimer laser irradiation, which is used for modifying textile surface, which comprises following steps: firstly, placing an object which will be processed, secondly, regulating the distance between the excimer laser irradiation and textile, thirdly, regulating the pressure strength in an excimer laser irradiation processing chamber, fourthly, processing by irradiating, and irradiating the object which will be processed for 0.1-0.5min. The method of the invention for modifying the surface of the textile is highly effective and convenient. The hydrophilicity of the textile surface which is modified is greatly increased, the appearance dying depth is also improved, and the influence for warp and weft breaking strength is not big.

Description

technical field [0001] The invention belongs to the field of surface modification of textiles, in particular to a method and a device for treating the surface modification of textiles by an excimer ultraviolet light source. Background technique [0002] The clean production technology of waterless dyeing and finishing is a subject that people have been exploring for a long time, and it is also an ideal model for textile processing in the 21st century. The research on the anhydrous activation treatment technology of textile surface that is currently being developed has a history of about 30 years. The methods used include conventional incoherent ultraviolet light source irradiation (low pressure, medium and high pressure mercury lamp, xenon arc lamp, etc.), UV laser irradiation and plasma glow discharge. Conventional incoherent ultraviolet light sources have low ultraviolet luminous efficiency, weak light intensity, and too slow processing speed, which has no practical value...
