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.
