Description
Technical Field
The invention relates to the technical field of functional polyester fibers, in particular to a preparation method and application of a plant traditional Chinese medicine antibacterial anti-mite functional polyester fiber.
Background
The antibacterial anti-mite fiber and the textile thereof are produced under the conditions. The antibacterial anti-mite textile has two production methods: one is a method adopting functional finishing; the other is developed by directly adopting antibacterial anti-mite fiber. At present, the production of antibacterial and anti-mite textiles by directly adopting antibacterial and anti-mite fibers is the main development direction.
The functional agents used in the antibacterial and anti-mite fibers can be roughly divided into three categories, one category is inorganic antibacterial and anti-mite functional agents, such as metal inorganic salts and antibacterial zeolite, and the inorganic antibacterial and anti-mite functional agents are easy to absorb by human bodies through human skin and bury hidden health troubles because the inorganic antibacterial and anti-mite functional agents contain heavy metal ions. The other is organic (synthetic) antibacterial and anti-mite functional agent, such as quaternary ammonium salt, nitrogen compound and the like, and most of the organic antibacterial and anti-mite functional agents belong to the category of pesticides strictly speaking, and have certain irritation and toxic and side effects on human skin. And the other is a natural antibacterial anti-mite functional agent, such as plant traditional Chinese medicine extracts, and the natural antibacterial anti-mite functional agent is safe, non-toxic, free of side effects, friendly to human and livestock, green, environment-friendly and free of pollution to the environment. Therefore, the plant traditional Chinese medicine is more and more popular in the market as the antibacterial and anti-mite functional agent.
The polyester fiber (filament) has many excellent characteristics, and is the synthetic fiber with the largest usage and the widest application range in the world at present. At present, functional agents used for functional polyester fibers (filaments) with antibacterial and anti-mite functions are generally inorganic materials, such as silver ions, copper ions and the like. As silver ions and copper ions belong to heavy metal materials, the silver ions and the copper ions have potential harm to human health and have great influence on the environment, and some countries prohibit the use of the functional agent as an additive of functional fibers. The plant traditional Chinese medicine extracts for preparing the polyester fibers with the antibacterial and anti-mite functions are obtained by extracting and purifying a plurality of commercially available plant traditional Chinese medicine extracts for a plurality of times by a scientific method, and keeping high-temperature-resistant components and functional active components, so that the active components are not influenced by high temperature in the melt spinning process of the polyester fibers (filaments) to produce the polyester fibers (filaments) with the antibacterial and anti-mite functions of the plant traditional Chinese medicine.
The existing polyester fiber is compounded by adopting plant traditional Chinese medicines, although the polyester fiber has an antibacterial function, PET adopted by the fiber is a continuous phase, and traditional Chinese medicine powder is a disperse phase, so that the interfacial compatibility after blending is problematic, and a void structure is generated, so that the strength performance and the surface are easy to mildew, and the use of the product is influenced.
