Abstract

The invention relates to environmental protection pulp for a fine denier filament pulp yarn, which is prepared from the following monomers by an emulsion polymerization method: 0.9-2.5 percent of crylic acid, 2.5-5 percent of methacrylic acid, 7.2-12.5 percent of ethyl acrylate, 1.8-3.75 percent of methyl methacrylate and 0.9-2.5 percent of styrene. The pulp also comprises 70-80 percent of deionized water, 0.15-0.25 percent of emulsifying agent, 0.3-0.9 percent of initiating agent, 0.8-1.2 percent of ammonia water, 0.1-0.15 percent of defoamer and 0.5-1 percent of penetrating agent. The environmental protection pulp of the invention has the advantages of simple preparation process, no organic solvent which is harmful to the human body in the processes of preparation and use, tenderness, safety, wide raw material source, low cost, high adhesion of the pulp and fibers, high permeability, coating property and film forming property and high popularization and application value and can strengthen the abrasion resistance of the fine denier filament, ensures that the fine denier filament can not generate a pulp falling phenomenon in the weaving process and is easy to desize in the after-treatment process.

Description

technical field [0001] The invention relates to a textile size, in particular to an environment-friendly size for fine denier silk sizing. Background technique [0002] Most of the existing domestic fine-denier sizing sizing materials, especially those for nylon fine-denier sizing, contain a certain amount of formaldehyde, alkylphenol polyoxyethyl ether (APEO) and perfluorooctane sulfonic acid (PFOS) ), etc. These substances are carcinogenic to the human body and do not meet international environmental protection requirements. At present, gray fabrics woven from nylon fine denier silk sizing with domestic sizing materials, even after desizing, dyeing and other processes, the content of APEO and PFOS in the product still exceeds the standard, which will not only cause harm to the human body, but also choke The throat of the export of my country's nylon textiles has been blocked, and the international competitiveness of my country's nylon textiles has declined. For this reaso...
