Aromatic polypropylene fiber and preparation method thereof

Abstract

The invention belongs to the textile field, and particularly relates to aromatic polypropylene fiber. The aromatic polypropylene fiber is prepared from materials in parts by weight through melt spinning as follows: 100 parts of fiber-grade PP (propene polymer) slices and 1-4 parts of aromatic polypropylene master batch, wherein the aromatic polypropylene master batch is prepared from the fiber-grade PP slices as well as 3%-6% of preprocessed nano essence, 1%-3% of an antioxidant, 0.1%-1% of a lubricant and 0.5%-2% of a dispersing agent by weight of the fiber-grade PP slices through melt blending and extrusion, and the preprocessed nano essence is nano essence subjected to coating processing through a hydroxypropyl-beta-cyclodextrin solution in a fluidized bed. The problem of uniform distribution of nano essence with small particle sizes in a PP matrix is solved, efficient and long-acting aromatic polypropylene fiber is prepared through melt spinning, and a method is simple, easy to implement and suitable for industrial popularization and utilization.

Description

technical field [0001] The invention belongs to the textile field, and in particular relates to an aromatic polypropylene fiber and a preparation method thereof. Background technique [0002] The development of functional fibers is a symbol of the progress of modern fiber science. The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has certain special functions in addition to the physical and mechanical properties of ordinary fibers. With the improvement of people's living standards, the demand for functional fibers is increasing. Aromatic functional fibers are a major category. An olfactory sensation that brings comfort and enjoyment. [0003] As a kind of fiber that can emit...

Problems solved by technology

[0003] As a kind of fiber that can emit fragrance, a lot of researches have been carried out at home and abroad. There are many patent literature reports on aromatic fibers. JP61063716 introduces a sheath-core fiber with lasting aromaticity; Chinese invention patent CN85108805 introduces an aromatic sheath-core composite fiber suitable for bedding. High requirements

As another example, Japanese patent JP61296118 introduces the manufacture of a kind of aromatic polyester fiber. By adding three kinds of substances into the polyester for melt blending and spinning, the fragrant fiber is obtained. The same processing process is complicated, and the substances are not easy to achieve full mixing.

As another example, Japanese Patent JP1282311 is to obtain a long-term fragrance, that is, the oil-absorbing polymer and thermoplastic polyester are spun through a static mixer, and the obtained fiber is immersed in a spice or liquid during post-treatment to obtain a fragrance fiber, but this processing The disadvantage of the method is that not only the equipment is complicated, but also the processing technology and processing process are also complicated.
