Problems solved by technology

Chinese patent CN102675625 introduces a method for preparing an environmentally friendly water-soluble phthalocyanine containing PEG side chains, but this method still requires chemical reactions and multiple purifications
The above methods still belong to the category of chemical modification. Although they help to improve the dispersion of phthalocyanine in the polymer matrix, there are still problems such as complicated operation and high cost.
[0004] At present, there are no reports or patents that can uniformly disperse phthalocyanine in the polypropylene matrix by physical modification.

Abstract

The invention relates to a preparation method of antibiosis and deodorization polypropylene fibers. The method comprises the following steps: dissolving metal octocarboxyphthalocyanine in a small amount of a solvent, adding the obtained solution to a polymer matrix, stirring the obtained solution until uniformity, removing the solvent, and fully drying the obtained material to obtain a metal octocarboxyphthalocyanine uniformly-dispersed polymer matrix mixture represented by general formula 1; and adding the mixture to polypropylene slices according to a certain ratio to prepare the polypropylene fibers with different proportions of the mixture. The problem of unable application of phthalocyanine in the fiber and fabric modification field due to agglomeration blocking after solvent volatilization is solved in the invention. Compared with phthalocyanine chemical modification methods, the method disclosed in the invention has the advantages of simple operation, short time, no need of a catalyst, environmental protection, safety and energy saving. The polypropylene fibers prepared in the invention have the advantages of stable phthalocyanine adhesion, good fatigue resistance, and substantial antibiosis and deodorization effects.

Description

technical field [0001] The invention belongs to the field of preparation of antibacterial and deodorant fibers and fabrics, in particular to a preparation method of antibacterial and deodorant polypropylene fibers. Background technique [0002] With the improvement of people's living standards and the continuous improvement of the quality of life, people's requirements for environmental quality are also getting higher and higher. In recent years, environmental pollution has become more and more serious, and air purification devices have become more and more important to people's lives, and polypropylene non-woven fabrics, fibers and fabrics are the best choices for air purification materials and filter materials. At present, the purification material is mainly attached to activated carbon to absorb odor by physical methods, which cannot fundamentally eliminate odor. Therefore, chemical methods to eliminate odor are becoming more and more important. [0003] Phthalocyanine i...
