AI Technical Summary

Benefits of technology

The invention relates to an improved type that can be used on fabrics made from materials like silicone rubber or plastics without causing damage during cleanings such as wipes. This new material contains special chemical groups called urethanes attached by covalently bonds between nitrogen atoms within it (N). These chemistry allows for strong adhesion even at room temperature while still maintaining its effectiveness over time.

Problems solved by technology

In this patented technical problem addressed in this patents text relates to finding ways for reducing or eliminating certain substances that can harm aquatic organisms such as algae when they grow inside fabrics made from materials like polyester fibers used during manufacturing processes.

Abstract

The invention provides a fluorine-free water-proofing agent and a preparation method thereof as well as a textile. The fluorine-free water-proofing agent free from fluorine element comprises the following components in percentage by weight: 10-20% of polyurethane, 10-20% of paraffin, 1-10% of a surfactant, 0.001-10% of an assistant and water. The fluorine-free water-proofing agent provided by the invention has a good waterproof effect and is environmental. According to the fluorine-free water-proofing agent, polyurethane is used as a key component. Compared with the prior art, the fluorine-free water-proofing agent has better waterproof effect and durability.
