It is widely applicable to cotton and its blended textile processes, achieving excellent whiteness and wicking effect in conventional annealing / scouring / bleaching processes. It contains no alkylphenol polyoxyethylene ethers or organophosphates, causing no environmental pollution and simplifying and making textile pretreatment processes more environmentally friendly.

A polyimide film surface modifier and its preparation method and application

The present invention relates to the technical field of polyimide film surface modifiers, and more particularly to a polyimide film surface modifier and its preparation method and application. The polyimide film surface modifier is measured in concentration and includes: amines 9.0-10.0 g / L; quaternized polyvinyl imidazole 0.7-0.8 g / L; inorganic salt 0.2-0.4 g / L; alkylphenol polyoxyethylene ether 0.25-0.35 g / L; reducing agent 1.8-2.5 mL / L; inorganic base 0.8-1.0 g / L; alcohol amines 2.5-3.5 mL / L; the rest is deionized water. After the polyimide film surface modifier is metallized to the PI film surface, full coverage is obtained in a relatively short time, so that the PI film surface produces more chemical groups of phenolic groups and amines, plasma physical modification treatment can be exempted, and there is no need to use a PI adjuster, and the function of a pore-forming agent is combined, thereby reducing the cost of metallization treatment of the polyimide film surface.
