Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of imparting a metallic pattern to a fabric by applying electroless plating.

BACKGROUND ART Conventionally, the production of fabrics having metallic patterns has been limited to weaving fabrics using gold and silver threads as pattern threads and pasting metal foils onto fabrics using stamping foil or the like. The former is used for clothing such as obi fabrics, but because special threads are used, there are limits to the weaving method, and there are limits to the fabrics and patterns that can be applied. In addition, the latter involves attaching hard metal foil of a completely different nature to the fabric, which impairs the texture and breathability of the fabric. Although it is sometimes used for stage costumes, it cannot be widely used for clothing. There wasn't.

Purpose of the Invention The present invention eliminates the drawbacks of such conventional methods and provides a method for effectively imparting a metallic pattern to any fabric without significantly impairing the texture or breathability of the fabric. The purpose is to

Structure of the Invention The method of the present invention is characterized in that the surface of the fabric is chemically and/or physically treated to form areas with different electroless plating speeds in a pattern, and then electroless plating is performed. do.

Electroless processing of the treated and non-treated surfaces of the fabric can be applied, such as deformation of the tissue surface by hammering or embossing. In particular, any treatment with a water repellent, coating with a hydrophilic resin, embossing or a combination thereof can be effectively utilized.

Any silicone-based, paraffin-based or fluorine-based water repellent can be used as the water repellent, and since the electroless plating solution does not adhere to the water repellent applied area, it remains as a non-plated area.

Next, metal compounds that act as catalyst poisons, such as tin, bismuth,
Application of compounds containing cadmium, antimony, lead, zinc, etc. has the effect of slowing down the electroless plating rate in the applied area, making complete plating impossible. These compounds are best applied as paints containing resins and the like.

Furthermore, as the paint that is not hydrophilic, that is, water repellent, general synthetic resin paints such as polyamide resins and nitrocellulose resins can be used.

The catalytic process for electroless plating works strongly on the areas where the hydrophilic paint is applied, forming a clear and durable metal pattern.

Furthermore, when hitting with a hammer or embossing, the structure of the fabric surface is physically etched and flattened, making the plating effect as described above even stronger, and the processed surface has a soft spread due to electroless plating. Sarel formed into a metal pattern with a shank. Furthermore, when embossing is performed after water repellent treatment, the water repellent coating on the embossed area is destroyed, so a bright metal coating is formed only on the embossed surface.

Note that any general method can be used as the electroless plating method, and electroless plating and displacement plating, electrolytic plating, electrolytic corrosion, etc. may be used in combination.

Furthermore, in the present invention, when a metal that easily discolors is used, a protective film of metal such as In or Ni or synthetic resin may be formed on the metal pattern.

However, in the present invention, instead of plating the fabric, the metal film is formed uniformly bonded to the structure on the entire front and back of the fabric, so generally a protective film is not required and a product with a very good texture can be obtained. be able to.

Example (1) The warp is made of polyester fiber 50D/12F, and 75D
/24F is used as the weft to form a woven fabric, which is screen-printed with a red water-repellent paint in an arabesque pattern. After heating and drying, it is plated with silver using a copper mirror reaction, and then electrolytically plated with indium to prevent the silver from discoloring. did.

The product is made of silver with a red arabesque pattern embossed on it.Example (2) Polyamide fiber 20D/IF is woven using polyamide fiber 20D/IF for the warp and weft. A water repellent is applied to the entire surface of the gauze fabric, and then a width of 5
The diagonal striped pattern on the shoulders is embossed, and it is further plated with copper using copper mirror reaction.

As a result, the embossed part is heated and pressurized.
The warp and weft became somewhat flattened, the weave structure changed, and the water-repellent film was also destroyed, resulting in copper adhesion and a beautiful copper-colored fabric with a diagonal striped pattern.

Furthermore, this fabric was treated with chromate to change the copper-colored pattern to an iridescent tone, and a synthetic resin coating was formed to prevent discoloration, resulting in a fabric with a bold iridescent pattern.

Example (3) A hydrophilic synthetic resin was applied to a woven fabric made of polyamide fibers 50D/15F as warp and weft yarns in a shark pattern (diameter 0.2 to 0.0 mm).
31111 dotted pattern) and stamped with stannous chloride 4F! /
After washing with water, it was immersed in a solution containing palladium chloride 1 g/l and HC6lax/l, washed with water, and then electroless nickel plated.

As a result, a very fashionable printed fabric was obtained, with the dotted pattern of the shark pattern shining strongly in silver on a dark silver background.

In addition, when washing with water after the catalytic treatment with palladium chloride in the above-mentioned method was carried out for about three times as long as usual, the fabric other than the synthetic resin printed area remained white without being plated. Next, this was dyed black using disperse dye, resulting in a very elegant printed material with beautifully arranged silver shark patterns on a black background.

Example (4) A woven fabric treated with a water repellent similar to Example (2) was embossed with a 20M diameter polka dot pattern, and then immersed in a silver reaction solution for 30 minutes.
C for 60 seconds, washed with water, and dried.

The product is a textured fabric with a sharp silver polka dot pattern that stands out on a gray background.

When the same method as described above was repeated with the immersion time in the silver reaction solution being 180 seconds, a beautiful cloth with brilliant silver polka dots scattered on a grain-like silver background was obtained.

Both fabrics were treated to prevent discoloration through the formation of a chemical conversion film and resin coating.

Example (5) A hydrophilic synthetic resin liquid was printed on a floral pattern on a woven fabric treated with a water repellent as in Example (2), and after drying, a silver mirror reaction treatment was performed at 350C for 1 minute. As a result, there was no reaction at all in the untreated area, and a silver mirror reaction occurred only in the floral print area. After washing and drying, the front and back sides of the printed pattern are colored pink for the petals, brown for the branches, and green for the leaves using transparent resin to match the printed pattern. By applying a protective coating, we obtained a printed fabric with a beautiful metallic luster and a nice texture. The fabric remains intact except for the pattern, making the fabric extremely tactile and easy to handle.

Effects of the Invention According to the present invention, a beautiful metal-patterned fabric can be obtained without substantially impairing the feel or air permeability of the fabric. In addition, the formed metallic film with a metallic pattern uniformly covers the structure of the base fabric, that is, the surroundings of the filaments, so it has strong fastness.
The product of the present invention can be widely used for clothing.
