The liquid repellent membrane is a monomolecular membrane of a fluorine-containing organic compound that binds to a surface of the base fabric through a binding moiety represented by —Z—O—* (wherein Z represents an atomic group containing a Si atom, and * represents a binding site to the surface of the base fabric) and includes a perfluoroalkyl group having 4 or less carbon atoms at a terminal, and the fluorine-containing organic compound undergoes intermolecular bonding between the fluorine-containing organic compounds adjacent to each other by mutual binding of Z in the formula.

The present invention is directed to a substrate, in particular textile material to which one or more antimicrobial and/or hydrophilic and/or stain release agents are adhered. The agent(s) is/are adhered to the substrate in such a manner that they are not released from the textile even if the textile is wetted or washed, so that the textile is reusable. Washability and/or usability of the textile are improved where one or more hydrophilic and/or stain release agents are adhered to the textile. The substrate can be used, e.g., in a reusable sanitary napkin or other hygiene product. The structure of the hygiene product is disclosed, together with a process of attaching the different layers of the hygiene product together by ultrasonic welding. The invention further relates to a method of finishing a substrate by applying and binding antimicrobial and/or hydrophilic and/or stain release agents to the substrate so that the agents are essentially irreversibly adhered to the finished substrate.

Provided is a method for manufacturing a water-repellent knitted fabric and a water-repellent knitted fabric. The method includes: dyeing a yarn; obtaining a knitted fabric by knitting the dyed yarn which is dyed in the dyeing of the yarn; dipping the knitted fabric in a water-repellent liquid to allow the water-repellent liquid to penetrate into a structure of the dyed yarn and to be coated on a surface of the dyed yarn; dehydrating the knitted fabric after the dipping of the knitted fabric and then incompletely drying the knitted fabric while moisture remains in the dyed yarn; adhering the water-repellent liquid applied to the knitted fabric by applying heat to the knitted fabric after the dehydrating of the knitted fabric; washing the knitted fabric using water after the adhering of the water-repellent liquid; and drying the knitted fabric after the washing of the knitted fabric.

A fabric treatment composition is provided that includes at least one zeta potential modifier, a fluoropolymer and a hydrophobic agent with a melting point or glass transition temperature below 100 C., for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel. Fabric treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh the fabric protection benefits imparted to the fabric, with the proviso that an intermediate rinsing step essentially devoid of added surfactantis used after the washing cycle and prior to the fabric treatment step. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits.
