Problems solved by technology

[0007] 1. In the process of low-temperature plasma treatment, only the etching effect of air low-temperature plasma is used, 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 through physical effects. 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 the plasma atmosphere will be caused by the presence of free water, adsorbed water and other volatile impurities in the fabric during the low-temperature plasma treatment. 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 present invention utilizes low-temp. plasma body to treat and implement surface cleaning, etching and activaling processes of the fabric, and adopts inorganic metal salt-polymer complex coating layer, and uses hydrogen gas plasma body to make reduction so as to obtain the chemically-bonded surface metallized fabric between coating layer and base body. Said invented method is simple in process, effective, can prevent treatment of chemical waste liquor, its product can be used in microwave and electromagnetic shielding effect, reflective, heat-insulating, decorative and fire-resisting 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 c...
