High-activity tea carbon fiber for shoe material and preparation method of high-activity tea carbon fiber

Abstract

The invention discloses a high-activity tea carbon fiber for a shoe material and a preparation method of the high-activity tea carbon fiber. The high-activity tea carbon fiber is characterized in that agricultural and forestry waste tea leaves, tea residues and tea stems are used as raw materials, a low-temperature calcination activation modification technology is adopted to prepare tea carbon with high tea polyphenol content, and an active crushing process is adopted to prepare high-activity functional tea carbon; then the high-activity tea carbon fiber for the shoe material is prepared by a melt extrusion method; the polyphenol content in the obtained product is 10-500 ppm, the bacteriostasis rate of the obtained product to staphylococcus aureus is larger than 95%, the bacteriostasis rate of the obtained product to escherichia coli is larger than 90%, the bacteriostasis rate of the obtained product to streptococcus albus is larger than 85%, the deodorization performance is so good that an acetic acid elimination rate is more than 99%, an oxalic acid elimination rate is more than 97% and an ethylenediamine elimination rate is more than 97%; the far-infrared emission rate is greater than 0.9, and the far-infrared radiation temperature rise is greater than 1.5. When being applied to shoe material fabric fibers, the high-activity tea carbon fibers have excellent antibacterial and deodorant performance, and ensures that the shoe material has no peculiar smell; and trace tea polyphenol has excellent oxidation resistance, and plays a very important role in improving the microbiological balance of the microenvironment of a shoe material, especially the interiors of shoes.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a high-activity tea charcoal fiber for shoe materials and a preparation method thereof. Background technique [0002] Tea charcoal is a high-activated carbon material obtained after carbonization of agricultural and forestry wastes. Tea fiber is made by adding tea polyphenols, tea pigments and other antibacterial agents contained in tea into the viscose spinning solution in the form of fine particles or solutions. A kind of viscose fiber with antibacterial and deodorizing functions produced by conventional wet spinning and spinning technology is widely used in the fields of home textiles and personal clothing. Tea polyphenols contained in tea have broad-spectrum antibacterial properties. However, in the conventional tea charcoal preparation process, the temperature is higher and the calcination process above 400 ° C is often used, and the tea polyphenol con...

AI Technical Summary

Problems solved by technology

However, in the conventional tea charcoal preparation process, the temperature is high and the calcination process above 400 ° C is often used, and the tea polyphenol content is basically no residue, resulting in limited antibacterial properties of the tea charcoal material.

[0003] Chinese patents of a tea charcoal water purification material and its preparation method and application (CN201810172207.5) and a tea charcoal and its preparation method (CN201710897310.1) disclose the preparation process of tea charcoal materials, which mainly adopt high-temperature calcination process , to prepare tea charcoal materials with high porosity, but due to the loss of active ingredients such as tea polyphenols after high-temperature calcination, resulting in poor antibacterial and antibacterial activities, so its porous structure is mainly used for water treatment or materials. Adsorption and other fields

The Chinese patent continuous high-strength core-skin composite tea-charcoal polyester fiber (ZL201210193128.5) reports a continuous high-strength core-skin composite tea-charcoal polyester fiber. Through the core-skin composite structure and a series of unique design of filtration, melting, extrusion and other processes, ester overcomes the strength, moisture absorption, breathability, dyeability, adsorption and antibacterial properties of synthetic fibers in the prior art that cannot coexist. The technical problems; the strength, moisture absorption, breathability, easy-to-dye, adsorption, antibacterial and comfort properties of the fiber are several times higher than that of the same fiber, and the comfort performance of the fiber and harmless to the environment and human body are also omitted. Subsequent dyeing, the beneficial advantages of enhanced strength, moisture absorption, breathability, and strong adsorption post-treatment

However, the tea charcoal preparation process mainly adopts the conventional high-temperature carbonization process, and its grinding process is relatively easy, but there is no explanation for the tea polyphenols in tea charcoal, and there is no report for tea charcoal with high content and high activity
