Sea mud-containing multifunctional polyester fiber and preparation method thereof

Abstract

The invention provides a sea mud-containing multifunctional polyester fiber and a preparation method thereof. The fiber is prepared from the following raw materials in percentage by weight: 70 to 95 percent of polyester chip, 2 to 18 percent of sea mud powder, 0.3 to 2 percent of a staphylea bumalda seed extract, 1 to 3.5 percent of a Blumea aromatica (Wall. )DC. extract, 1.6 to 5 percent of a flemingia philippinensis extract and 0.1 to 1.5 percent of a coupling agent. All the raw materials are treated and blended in various ways and then are conveyed into melt spinning equipment by a conventional melt spinning method for blend spinning, so that the sea mud-containing multifunctional polyester fiber is obtained; the sea mud-containing multifunctional polyester fiber is strong in fragrance and high in skin friendliness, has functions of resisting bacteria, removing odor, preventing ultraviolet rays, killing acarus, expelling mosquitoes, protecting the skin and the health, is good in effect, can work for a long time, shows higher spinnability, hygroscopicity, breathability, dyeing uniformity and mechanical property, is excellent in serviceability, and can be widely applied. Therefore, sea mud resources are fully used, and the sea mud-containing multifunctional polyester fiber has extremely high economic value and environmental protection value.

Description

technical field [0001] The invention relates to a multifunctional polyester fiber containing sea mud and a preparation method thereof, belonging to the technical field of functional chemical fibers. Background technique [0002] Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. The commodity name is polyester, referred to as PET fiber, which is the largest variety of synthetic fiber. It not only has high strength, good elasticity, heat resistance, good acid and alkali resistance, high dimensional stability, but also can be purely spun or blended with cotton, wool, silk, hemp and other natural fibers and other chemical fibers in any proportion. With excellent performance, it is widely used in the manufacture of textiles such as clothing, underwear, socks, sportswear, bedding, and sanitary dressings. However, polyester fibers also have disadvantages such as poor hygroscopicity, low an...

Problems solved by technology

However, due to the strong fishy smell of sea mud, low permeability coefficient and low absorption capacity, its active ingredients are difficult to be fully absorbed by the skin, and the use effect is poor.

Moreover, sea mud is rich in colloids, and there are a large number of inorganic ions between the layers, showing hydrophilic and oleophobic properties, which limits its application in many fields such as chemical fibers.

After searching, so far, there is no precedent of implanting sea mud into polyester chips and melting spinning into multifunctional polyester fibers at home and abroad, and there are no literature reports.
