Problems solved by technology

[0002] Since most of the commonly used waterproofing agents are fluorine-containing systems, their compatibility with other functional finishing agents (such as anti-ultraviolet finishing agents and antibacterial agents) is poor. In the case of oil floating, the working fluid cannot be used to finish the fabric, and fabrics with composite functions cannot be obtained
If a step-by-step finishing method is adopted, such as antibacterial finishing first, then waterproof finishing, or anti-ultraviolet finishing first, and then waterproof finishing, although the problem of unstable working fluid is avoided, the antibacterial effect of the final fabric will The anti-ultraviolet effect and waterproof effect are poor, the reason is that the fluorine-containing waterproof agent will affect the effect of antibacterial agent and anti-ultraviolet finishing agent, and at the same time, antibacterial agent and anti-ultraviolet finishing agent will also affect the effect of fluorine-containing waterproof agent
Therefore, the functional fabrics currently produced only have waterproof effects, only anti-ultraviolet effects, only antibacterial effects, or only anti-ultraviolet and antibacterial effects, and there is no production method that combines waterproof, anti-ultraviolet and antibacterial functions into the same fabric.

Abstract

The invention provides a compound function fabric and a preparation method thereof. The compound function fabric is prepared from a gray fabric padding water-proofing agent, an anti-ultraviolet finishing agent and an antibacterial agent, wherein the water-proofing agent is a non-fluorine water-proofing agent, the non-fluorine water-proofing agent is composed of the following components by mass percent: 5-35% of non-fluorine polymer with a hydrophobic group, 5-20% of modified polyethylene wax, 1-10% of self-crosslinking polyacrylic acid emulsion, 1-10% of polyacid ester emulsion and the balance of water. The non-fluorine water-proofing agent which has good compatibility with the anti-ultraviolet finishing agent and the antibacterial agent is used for synergetically treating the fabric in combination with the anti-ultraviolet finishing agent and the antibacterial agent so as to obtain the compound function fabric. The waterproof level of the obtained compound function fabric is the third or above, the ultraviolet protection coefficient UPF average value is greater than 160, the test organism reduction percentage of the colibacillus is 96% and more, the test organism reduction percentage of the staphylococcus aureus is 96% and more, the test organism reduction percentage of the candida albicans is 96% and more, and the fabric has good antibacterial performance.
