Problems solved by technology

[0002] In the past, compounds containing long fluorocarbon chains were mostly used as waterproof finishing agents to obtain fabrics with low surface free energy. Although compounds containing fluorine systems have better finishing effects, such finishing agents are expensive. It is found that fluorine-containing chemicals are difficult to biodegrade and cause potential harm to the environment and human health. Therefore, how to make environmentally friendly finishing agents achieve the finishing effect of compounds with long fluorocarbon chains is an important issue in the development of functional fabrics today.
[0003] In addition, due to the poor compatibility between the hydrophobic finishing agent of the fluorine-containing system and other functional finishing agents (such as antibacterial finishing agents), the working fluid prepared by adding the finishing agents together is unstable, and there will be stratification and oil floating. It cannot be used to finish fabrics, and fabrics with composite functions cannot be obtained
If a step-by-step finishing method is adopted, such as antibacterial finishing first, and then waterproof finishing, although the problem of unstable working fluid is avoided, the antibacterial effect and waterproof effect of the final fabric are poor, because the fluorine-containing waterproof finishing agent It will affect the effect of antibacterial finishing agent, and antibacterial finishing agent will also affect the effect of fluorine-containing waterproof finishing agent

Abstract

The invention discloses a waterproof and antibacterial composite functional fabric. The fabric is obtained by padding grey cloth with a waterproof finishing agent and an antibacterial finishing agent. The waterproof finishing agent is prepared from, by weight, 10-35% of SiO2 sol, 5-20% of modified polyethylene wax, 5-15% of vinyl acetate-ethylene copolymer emulsion, 1-10% of polyisocyanate emulsion and the balance water. The antibacterial finishing agent is prepared from, by weight, 5-25% of a quaternary ammonium salt modified compound, 5-15% of a halamine compound, 5-10% of polybasic carboxylic acid, 1-5% of sodium hypophosphite and the balance water. The waterproof and antibacterial composite functional fabric has the hydrophobic and antibacterial functions, and is environmentally friendly, outstanding in performance and high in durability.
