Description
Technical Field
The invention relates to the field of textile production, in particular to application of an environment-friendly fluorine-free waterproof agent with improved continuous processing stability and good coating fastness to umbrella cloth.
Background
The composition of water repellents for textile fibres has long been known in the art. In general, the most market-share water repellent is typically a fluorine-containing water repellent. Fluorine-based water repellents are generally composed of oligomers or polymers having a large number of fluorine-containing groups, and can impart good water and oil repellency to fiber materials. However, in recent years, as concerns about environmental ecology caused by fluorine-containing compounds have been increased, there is a need for a substitute which does not contain fluorine and provides a fiber with good water-repellent properties.
The fluoride PFOA (perfluorooctane sulfonyl compound) and PFOS (perfluorooctanoic acid ammonium) in the common waterproof agent at present belong to environment, human and animal unfriendly compounds, and have the advantages of bioaccumulation, genetic toxicity, stable performance and difficult degradation. With the improvement of environmental protection requirements, the environmental protection requirements on the waterproof agent are higher and higher, and the application of the waterproof agent is from 8-carbon waterproof agent to 6-carbon waterproof agent to fluorine-free waterproof agent. Especially, the products exported in Europe and America are always required to be free of fluorine. The existing fluorine-free waterproof agent usually contains active hydrogen or amino, and the fluorine-free waterproof agent is easily oxidized due to high processing temperature in the processing process, so that the waterproof agent is difficult to attach to umbrella cloth, and the waterproof performance of the product is finally reduced.
CN105088796A discloses a fluorine-free waterproof agent which is prepared by compounding hydrophobic polymer, paraffin and blocked polyurethane to obtain good waterproof performance and durability. CN103628324A discloses a waterproof agent compounded by alkyl methacrylate polymer and paraffin wax, which achieves the waterproof performance through long-chain hydrophobic polymer. The end-capped polyurethane compound or the alkyl methacrylate polymer dispersion liquid which is adopted only can bring about good initial waterproof effect and certain washing fastness, but has the defects of poor running stability in use, hard hand feeling of the finished fabric and the like. The alkyl acrylate waterproof agent also has the defects of complex preparation process, higher requirement on equipment, poor product reproducibility and the like.
Disclosure of Invention

In the technical scheme, on the basis of the existing umbrella fabric production process, the formula of the waterproof agent is adjusted, and compared with the conventional fluorine-free waterproof agent, the proportion of the stabilizer is increased, the softener is cancelled, and the proportion of the stabilizer is increased, so that the chemical balance is kept, the surface tension is reduced, and the environment-friendly fluorine-free waterproof agent can be better and more firmly combined on the umbrella fabric in the subsequent setting process; on the premise of ensuring that the waterproof effect meets the requirement, the probability of preventing the water from sticking to the roller is reduced, and meanwhile, the slipping condition of the cloth roll is reduced. By adding a proper amount of citric acid and acetic acid and maintaining the pH value of the processing liquid at 5-6, the continuous processing stability of the waterproof agent can be greatly improved.
