Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the problem that the surface of the wiping cloth made of ordinary polyester fiber has poor hydrophobicity, or after it is modified, the amount of dust generated and the content of non-volatile organic compounds exceed the standard, and the cleanliness decreases. After the coconut shell is pretreated, it is soaked in the supernatant prepared by using plant ash, vermicompost and deionized water compost, filtered, knocked on the filter cake, washed and dried to obtain dried coconut fiber, and then carbonized. After being pulverized, it is mixed with self-cultivated yeast mycelia suspension, heated and stirred, filtered, and the filter cake is dried, mixed with polyethylene terephthalate, melt-spun and other steps to obtain recyclable super Clean wipe method

example 1

[0022]First take successively 8g of glucose, 4g of peptone, 0.8g of yeast extract, and 25g of agar in 2L of deionized water, then transfer it to a pressure steam sterilizer, and sterilize it at 0.10MPa for 30 minutes to obtain a culture medium. Inoculate yeast with 10% of the inoculum, then transfer the inoculated medium to a constant temperature shaker, culture it at 180r / min, 35°C for 5 days, rinse the surface of the medium with 200mL of deionized water, collect and rinse liquid, to obtain mycelial suspension, and set aside; then take 600g plant ash and 20g vermicompost successively, place it in a beaker filled with 120mL deionized water, stir and mix with a glass rod for 10min, then compost in the dark for 6 days, and then Add 3L of deionized water, stir with a glass rod for 8 minutes, transfer to a centrifuge for separation, and collect the supernatant; then collect 2kg of coconut shells, wash them repeatedly for 5 times, and manually chop the coconut shells into 4cm long a...

Abstract

The invention relates to a preparation method of recyclable ultra-clean wiping cloth, which belongs to the technical field of textile preparation. In the present invention, after the coconut shell is pretreated, it is soaked in the supernatant liquid prepared by composting plant ash, vermicompost and deionized water, filtered, the filter cake is beaten, washed and dried to obtain dried coconut fiber, which is then carbonized and pulverized Finally, it is mixed with self-cultivated yeast mycelium suspension, heated and stirred, filtered, and the filter cake is dried, mixed with polyethylene terephthalate, and melt-spun and other steps to obtain recyclable ultra-clean wipe cloth. Add coconut charcoal powder in the wiping cloth prepared by the present invention, make it form microporous shape on fiber surface, increase the specific surface area of ​​fiber, make wiping cloth have good moisture absorption and moisture conductivity, improve its wiping performance; And after washing, Sun exposure and other methods, its adsorption capacity can be regenerated, and it can be recycled for many times.

Description

technical field [0001] The invention relates to a preparation method of recyclable ultra-clean wiping cloth, which belongs to the technical field of textile preparation. Background technique [0002] The surface of the wiping cloth is soft, easy to wipe the sensitive surface, does not remove fibers when rubbed, and has good water absorption and cleaning efficiency. Due to the above advantages, the wiping cloth is widely used, such as widely used in the production lines of semiconductor chips, microprocessors, and discs. Drivers, composite materials, LCD display products, circuit board production lines, precision instruments, optical products, aviation industry, PCB products, medical equipment, laboratories, dust-free workshops and other fields. For a long time, non-volatile residues and dust particle residues are important factors affecting the application of wipes. The residual amount of non-volatile residues (ie NVR value) and the residual amount of dust particle residues ...
