Technical Field

The invention relates to the field of textile fabrics, in particular to a porous local gold stamping fabric and a preparation process thereof.

Background

The gold stamping process transfers the aluminum layer in the electrochemical aluminum to the surface of a printing stock, so that the folding resistance and the toughness of the fabric are enhanced. Due to the effect of the aluminum layer, the fabric is good in conductivity, and the electrostatic effect can be eliminated. In addition, the fabric has high light reflectivity, and the aluminum layer can reflect a large amount of radiation heat brought by visible light and partial infrared light. Aluminum plating can enhance the heat insulation function of the fabric, but aluminum plated fabrics (most of which are gold stamped fabrics) in the market basically have the defects of poor air permeability and poor heat dissipation capability. Therefore, the fabric has practical significance for fabric development by reflecting external heat and simultaneously increasing the air permeability of the fabric.

The compression molding process is a method of curing and molding a composite article by heat and pressure in a closed mold cavity. Generally, a molding material or a mixture of a particulate resin and short fibers is placed in an open metal mold, the mold is closed and heated to melt the molding material, the mold cavity is filled with the molding material under pressure to form a molded article having the same shape as the mold cavity, the molding material is heated to further cause a crosslinking reaction of the resin to solidify the resin, or the molding material is cooled to solidify the thermoplastic resin and demolded to obtain a composite material.
