Problems solved by technology

That is, through etching, the smooth surface of the substrate becomes rough and uneven, and the bonding between the metal layer and the substrate is improved by physical action, and the degree of improvement is limited
[0008] 2. The vacuum drying process of the fabric is set after the low-temperature plasma treatment, so that it is possible that during the low-temperature plasma treatment, due to the presence of free water, adsorbed water and other volatile impurities in the fabric, the plasma atmosphere It cannot be controlled, which affects the treatment effect and the stability of product quality, and for the same reason, the vacuum degree of the system is not easy to increase, prolonging the auxiliary time of vacuuming and increasing the cost
[0009] 3. The production of metal coating adopts the method of vacuum plating, so there are still shortcomings of vacuum plating

Abstract

The invention belongs to the technical field of textile material functional finishing, and especially relates to a method for carrying out metallization processing upon fabric surface with a plasma technology. According to the invention, with low-temperature plasma processing, fabric surface cleaning, etching and activating are realized. An inorganic metal salt-polymer complex is used for coating; and hydrogen plasma is used for reducing, such that a surface metallized fabric is obtained, wherein a coating and a substrate are bonded with chemical bonds. The method is simple and effective. With the method provided by the invention, a defect of poor bonding force between a metal layer and substrate cloth in prior arts is overcome, and chemical waste liquid treatment is avoided. The product can be used in microwave and electromagnetic shielding materials, reflective and insulation materials, and decorative and fire preventing materials.

Description

technical field [0001] The technical field of the invention is the functional finishing of textile materials, in particular to a method for metallizing the surface of fabrics by using plasma technology. Background technique [0002] Metallized fabric is a kind of composite material. After metallized fabric, it has permanent antistatic properties; absorbs electromagnetic wave radiation; high reflectivity to radar waves; Reflection and absorption, flame retardant and other properties. In addition, metallized fabrics can enhance the aesthetics of garments with the attractive luster of the metal and improve garment insulation due to the reflective effect of the metal. Therefore, it has great potential application prospects. [0003] At present, the methods for metallizing the surface of fabrics mainly include vacuum deposition (also known as vacuum plating) and chemical plating. [0004] Vacuum deposition is to place the treated fabric under vacuum conditions to deposit vapor...
