Microporous photocatalyst bamboo charcoal polyester modified short fiber and preparation method thereof

Abstract

The invention belongs to the spinning field, and relates to a microporous photocatalyst bamboo charcoal polyester modified short fiber and preparation thereof. For the microporous photocatalyst bamboo charcoal polyester modified short fiber, the surfaces and the inside have irregular microporous structures, all micropores penetrate through each other, photocatalyst compound micro powder and bamboo charcoal micro powder are uniformly distributed on the external surfaces, surface layers and insides of the whole short fiber as well as the surface and inside of each micropore, and the photocatalyst compound micro powder and the bamboo charcoal micro powder respectively account for 1.05-1.35wt% and 1.8-2.6wt% of the short fiber. The fiber provided by the invention is an environment-friendly one which has the functions of harmful gas and harmful microorganism absorption, bacterium resistance, mould proofing, deodorization, far infrared wave transmission, moisture absorption, quick drying and the like. Under the irradiation of light rays, the absorbed harmful gas and harmful microorganisms can be decomposed into carbon dioxide and water, thus the functions of purifying the air and cleaning the environment are achieved. Under the condition of illumination, the short fiber can be circularly and continuously used and can play corresponding roles.

Description

technical field [0001] The invention belongs to the field of spinning, and relates to a functional fiber product, in particular to a functional environment-friendly polyester modified staple fiber (microporous photocatalyst bamboo charcoal polyester modified staple fiber) and a preparation method thereof. Background technique [0002] Modern consumers' demand for clothing and home decorations is not only focused on fashion, but also on functionality. Comfortable, safe and healthy clothing that is also environmentally friendly has become a consumption trend. [0003] In recent years, fiber manufacturers in developed countries, Japan, South Korea and Taiwan have achieved results in the research and development of functional textiles. Common functional fibers include fibers with relatively single functions such as moisture absorption and quick drying, antibacterial, anti-ultraviolet, far-infrared, and bamboo charcoal.

Problems solved by technology

[0003] In recent years, fiber manufacturers in developed countries, Japan, South Korea and Taiwan have achieved results in the research and development of functional textiles. Common functional fibers include fibers with relatively single functions such as moisture absorption and quick drying, antibacterial, anti-ultraviolet, far-infrared, and bamboo charcoal. Clearly smart fibers are still rare

The use effect is not very ideal. For example, the cross-shaped moisture-absorbing and quick-drying fiber often does not meet the relevant standards of INVISTA. It needs to be supplemented with hydrophilic treatment, but the washability after treatment is not durable; another example is bamboo charcoal. Fiber has strong functions of deodorization and adsorption of harmful microorganisms, but it will fail after a certain period of time and cannot be used continuously; most functional micropowders (such as antibacterial agents, bamboo charcoal micropowders, titanium dioxide micropowders, ceramic micropowders) are coated in chemical fiber The carrier is isolated from the outside world, unable to function and only the surface layer of fine powder plays a role, resulting in reduced efficacy and increased cost; most functional fibers with conventional polyester as the carrier have always had bottlenecks and local forbidden areas in the field of color spinning; the above problems Existence, it is necessary to develop a new generation of functional fibers and environmentally friendly fibers with higher efficiency, lower cost and wider application
