AI Technical Summary

Technical Problem

Cleanroom wipes are prone to static electricity buildup and fiber wear during wiping. Existing anti-static treatments and abrasion-resistant measures are not very effective, affecting wiping performance and safety.

Method used

A multidimensional network was constructed by grafting quaternary ammonium salt onto silanized graphene oxide and carbon nanotubes. Combined with hyperbranched polyurethane crosslinked framework and fluorinated nano-silica modification, a robust three-dimensional conductive channel and self-lubricating structure were formed through plasma pretreatment and ultrasonic impregnation process, achieving chemical anchoring and dynamic self-healing of the fiber.

Benefits of technology

It achieves durable antistatic properties and excellent abrasion resistance, reduces the risk of electrostatic discharge and fiber damage, and improves the service life and safety of cleanroom wipes.

Abstract

This invention relates to the field of cleanroom wipe technology, specifically to an antistatic cleanroom wipe and its preparation method. This invention overcomes the problems of static electricity buildup and poor wear resistance in cleanroom wipes. The invention first activates a polyester cleanroom wipe using plasma, then immerses it in a finishing solution containing a conductive liquid, fluorinated nano-silica, a hyperbranched polyurethane dispersion containing dynamic disulfide bonds, and vitamin C. After ultrasonic impregnation and two-dip-two-rolling, it undergoes step-temperature curing. This invention utilizes multidimensional micro-nano materials to synergistically construct a three-dimensional conductive network, employs dynamic disulfide bonds to impart self-healing capabilities to the material, and combines this with plasma-induced covalent grafting anchoring, thereby improving the antistatic and wear-resistant properties of the cleanroom wipe.
