Benefits of technology

This patented technology improves cleanliness during laundering operations without compromising their ability to resist wearing down over multiple cycles. It also prevents depositing onto clothing when exposed to rainwater while maintain its stability through hydrolysis with acidic agents that form strong covalent bondings between them. Additionally, this process does not cause any harmful residue left behind from previous steps like rinses beforehand. Overall, this technical results improve the performance and longevity of the clothes made up of synthetic fibers.

Problems solved by technology

This patented technical problem addressed in this patent relates to finding ways to reduce harmful levels caused by various compounds found naturally occurring within our bodies due to its role as an important component of life. These include both nontoxic and safe substance called Perflanilamide (PFAS).

Abstract

The invention provides a fluoride-free waterproof finishing agent and a preparation method thereof. The fluoride-free waterproof finishing agent comprises 10-15% of diethylene glycol monobutyl ether,5-10% of isopropyl acetate, 5-10% of methyl alkyl polysiloxane, 10-15% of glyceryl distearate, 5-10% of a surfactant fatty alcohol-polyoxyethylene ether AEO6, 2-10% of methylaminoethylaminopropyl polysiloxane, 5-10% of a blocked biuret triisocyanate cross-linking agent and 15-50% of soft water. The production method of the fluoride-free waterproof finishing agent is simple; only one set of high-shear emulsifying equipment is needed; and the raw materials including the diethylene glycol monobutyl ether, the isopropyl acetate, the methyl alkyl siloxane, the glyceryl distearate, the surfactant fatty alcohol-polyoxyethylene ether and the methylaminoethylaminopropyl polysiloxane are mixed together, then high-speed shearing and emulsification are performed, the blocked biuret triisocyanate cross-linking agent is added, and stirring is performed for 20 minutes to obtain the milky white viscous fluoride-free waterproof finishing agent.
