WATER AND OIL REPELLENCY TREATMENT OF FIBER PRODUCT

摘要

A method for producing a treated fiber product, which comprises the steps of (1) preparing a treating liquid containing a water and oil repellency agent, (2) adjusting the pH of the treating liquid to 7 or lower, preferably, to 3 or lower, (3) applying the treating liquid onto a fiber product, (4) subjecting the resulting fiber product to steam treatment, and (5) washing the fiber product with water, followed by dehydrating, wherein the water and oil repellency agent comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer and a fluorine-containing low molecular weight compound, and the water and oil repellency agent or the treating liquid comprises an organic salt. The method can be used for producing a fiber product exhibiting improved water and oil repellency.
