Japan's Toyobo Co., Ltd. Invents Stain Resistant Synthetic Fibers

Japan's Toyobo Co., Ltd. has invented ink stain resistant synthetic fibers in order to eliminate the disadvantages of the prior art. The object of the present invention is to provide a fluorine-based water and oil-repellent agent having a hydrophilic portion, a hydrophilic polyester-based resin, a non-hydrophilic fluorine-based water and oil-repellent agent, and an antifouling component containing a cross-linking agent to be optimized. An anti-fouling synthetic fiber cloth that substantially covers the surface of the fiber and greatly improves the SR antifouling property when the ink dirt is washed after repeated washing and repeated wear, and a method for producing the same.

The cross-linking agent of the present invention employs N-methylol-containing methylol melamine-based and bulk isocyanate (TDI/trimethylolpropane addition compound MEK-containing addenda) and the above-mentioned fluorine having a hydrophilic portion The use of water and oil repellents, hydrophilic polyester resins, and non-hydrophilic fluorine-based water and oil repellents at a specific blending ratio optimizes the amount of adhesion, and it can be found that the ink dirt has never had the durability of washing and abrasion. Excellent SR antifouling effect.
