Application of plasma surface processor in textile processing

Application of plasma surface processor in textile processing:

Textile industry is one of the industries with a long history of mankind, and also an important part of the industrial revolution. For a long time, in order to adapt to the changing consumer changes and cope with the increasingly severe environmental pressure, the textile industry has been developing and making progress. Textile plasma surface treatment technology is developing rapidly in China. The early plasma surface treatment technology has been replaced by new atmospheric plasma surface treatment technology. This new technology can improve the performance of a fabric by changing its surface properties.

Development Trend of textile Industry:

The textile industry provides a large number of jobs, creates a lot of wealth, and also has a huge impact on many industries, including mechanical engineering, polymer materials, chemistry and fuel. Since the 1990s, market drivers have included design and innovative fabrics, as well as increased investment in new technologies by industrialized countries to reverse the long-term decline of their textile and clothing industries. Earlier, the newly industrialised countries of East Asia that had succeeded in entering western markets were beginning to find their places being taken by a new generation of developing countries. In the whole textile industry chain, the competition between enterprises and western countries is increasingly intensified. Most countries with developed garment industry have established r&d centers, which are engaged in extensive improvement research and basic research work.

Textile plasma surface treatment:

The textile industry has long recognized that the surface performance of fabrics is a critical factor in many processing processes and applications, and the specific requirements for the surface performance of fabrics are often very different from that of base fabrics. The surface properties of the fabric not only determine the dyeing rate and color fastness of the fabric, but also determine the simplicity of the finishing process of the fabric, determine the binding strength between the coating and the base cloth, and play a crucial role in the biocompatibility between the coating and the base cloth. In addition, surface properties play a key role in the disinfection performance and biocompatibility of medical implants requiring liquid chemical treatment. Conventional textile processing technology consumes a large amount of energy and water resources in the processing process, causing serious water pollution, high cost and environmental damage. In the conventional fabric treatment process, the surface treatment of the fabric is carried out at the same time as the base fabric treatment, which will adversely affect the overall performance of the fabric. Therefore, the textile industry urgently needs to choose alternative surface treatment technology to reduce production costs, protect the environment, and produce new products with long life, high quality and good performance.

Certain properties of fabrics can be adapted to meet specific needs by changing the function or shape of the fabric surface. By etching the fiber surface, cracks and cracks can be created on the fiber surface. This etching can help enhance the wettability of the fabric, thus achieving more effective dyeing or deep dyeing. Conversely, by reducing the wettability of the fabric can be achieved waterproof effect. The new chemical function of fabric surface can promote the reaction between fabric surface and dyes, thus greatly improving the adhesion between layers.

It is a very complicated process to change the surface property of fabric by plasma surface treatment. The reactions initiated by the particles in the plasma usually occur at a depth of 10nm from the surface of the material. The radiation caused by short-wave ultraviolet radiation in the plasma is very deep, within 100nm of the surface. The working gas and other process parameters of plasma can change the interaction and range of action between the two reactions. The outermost layer of the fabric is only a few atoms thick, usually less than 1nm, but it determines how the fabric interacts with other media. The chemical composition of the outermost layer of the fiber surface determines the interlaminar bonding ability of the fabric and the suitability of the fabric for impregnation. The outermost layer of the fiber chemical structure and composition can be modified by plasma. The fabric surface treatment not only needs to choose the appropriate process parameters, but also the original surface performance of the fabric is also important.

At present, plasma surface treatment technology has been applied to the surface modification of textiles and the modification of base fabrics, which has successfully improved many kinds of fabrics from traditional fabrics to advanced composite fabrics. The results show that the surface energy of fiber and fabric can be changed by plasma surface treatment technology, so that the dyeing rate of polymer can be improved, and the color and washing resistance of fabric can be improved. After the study of the fiber surface, the strength, toughness and shrinkage resistance of various thermoplastic fibers were improved when they were placed in plasma. In recent years, the plasma-surface treatment technology has been used to make the fibers absorb water and deposit anti-wear coating on the fabric surface.
