Description
技术领域 technical field
本发明涉及到一种低温等离子体织物改性处理装置，特别涉及到一种电晕放电低温等离子体织物改性处理装置。The invention relates to a low-temperature plasma fabric modification treatment device, in particular to a corona discharge low-temperature plasma fabric modification treatment device.
背景技术 Background technique
为了得到更加理想的纺织工业原料，织物表面改性处理工艺一直受到人们的重视。化学浸泡法是目前最常用的织物表面改性技术，用特殊处理液将材料浸泡后，再经过烘干等工艺处理来完成织物的改性过程。这种方法的缺点是价格昂贵、工业复杂、还容易产生废气和废水污染。In order to obtain more ideal raw materials for the textile industry, the fabric surface modification process has always been paid attention to by people. The chemical soaking method is currently the most commonly used fabric surface modification technology. After the material is soaked in a special treatment solution, it is then dried and other processes to complete the fabric modification process. The disadvantage of this method is that it is expensive, industrially complex, and prone to waste gas and waste water pollution.
为了克服化学浸泡法的缺点，有人提出了光化学织物改性法，主要是利用紫外灯照射织物表面产生的活性自由基反应来引入其他基团实现改性目的。但这种工艺的处理速度太慢，产量无法满足纺织工业的生产需求。In order to overcome the shortcomings of the chemical immersion method, someone proposed a photochemical fabric modification method, which mainly uses the active free radical reaction generated by the ultraviolet light to irradiate the surface of the fabric to introduce other groups to achieve the purpose of modification. However, the processing speed of this process is too slow, and the output cannot meet the production needs of the textile industry.
低温等离子体织物表面处理技术是一种新兴的织物改性技术，该技术主要依靠等离子体中的高能电子和亚稳态粒子所引发的等离子体物理化学反应使织物表面得以改性。相关研究表明，氧等离子体可以提高织物的表面能，增强其可湿性、可染色性和抗静电能力；氟碳等离子体则可以降低气体的表面能，增强织物的憎水性。低温等离子体织物表面改性技术具有处理时间短，不伤纤维，成本低，无污染的特点。但是现有的低温等离子体技术难以产生大范围的均匀等离子体，而且往往需要经历气压转换过程且装置结构复杂，很难实现大规模工业应用。Low-temperature plasma fabric surface treatment technology is an emerging fabric modification technology, which mainly relies on plasma physical and chemical reactions caused by high-energy electrons and metastable particles in the plasma to modify the fabric surface. Relevant studies have shown that oxygen plasma can increase the surface energy of fabrics and enhance its wettability, dyeability and antistatic ability; fluorocarbon plasma can reduce the surface energy of gases and enhance the hydrophobicity of fabrics. Low-temperature plasma fabric surface modification technology has the characteristics of short processing time, no damage to fibers, low cost and no pollution. However, the existing low-temperature plasma technology is difficult to generate a wide range of uniform plasma, and often needs to undergo a pressure conversion process and the device structure is complex, making it difficult to achieve large-scale industrial applications.
