Abstract

A water repellent agent composition contains amino-modified silicone, a silicone resin, and alkylpolysiloxane. An amount of the alkylpolysiloxane mixed is 500 to 15,000 parts by mass with respect to 100 parts by mass of an amount of the amino-modified silicone mixed. A method for producing a water-repellent textile product includes a step of treating fibers with a treatment liquid including the water repellent agent composition.

First claim

The invention claimed is:

1. A water repellent agent composition consisting of aminomodified silicone, a silicone resin, alkylpolysiloxane, and water, and optionally one or more of the following:
fluorine-based polymers, aliphatic hydrocarbon, aliphatic carboxylic acid, aliphatic carboxylic acid esters, polyolefin, poly(meth)acrylic acid ester,
polymerization initiator, chain transfer agent, polymerization inhibitor,
polyfunctional isocyanate compound, a surfactant, an antifoaming agent, an organic acid, an inorganic acid, ethanol, isopropanol, glycerin, trimethylol propane, diethylene glycol, triethylene glycol, dipropylene glycol, propylene glycol, an antibacterial agent, an antifungal agent, a pH adjuster, a colorant, silica, an antioxidant, a refresher, catalysts, an emulsion stabilizer, organic solvents other than alkylpolysiloxane, a chelating agent, an antistatic agent, organo-modified silicone other than aminomodified silicone, a crosslinking agent other than the polyfunctional isocyanate compound, and penetrating agent;
wherein
the silicone resin consisting of MQ, MDQ, MTQ, or MDTQ as a constituent, where M has a formula (R″) 3 SiO 0.5 , D has a formula (R″) 2 SiO, T has a formula R″SiO 1.5 , and Q is SiO 2 ,
and R″ is a monovalent aliphatic hydrocarbon group having 1 to 10 carbon atoms or a monovalent aromatic hydrocarbon group having 6 to 15 carbon atoms, and
the alkylpolysiloxane is present in the water repellent agent composition in 925 to 6,000 parts by mass with respect to 100 parts by mass of an amount of the aminomodified silicone in the water repellent agent.

2. The water repellent agent composition according to claim 1 , wherein a functional group equivalent of the aminomodified silicone is 100 to 20,000 g/mol.

3. The water repellent agent composition according to claim 1 , wherein a functional group equivalent of the aminomodified silicone is 200 to 4,000 g/mol.

4. The water repellent agent composition according to claim 1 , wherein the water repellent agent is used to treat fibers, and the fibers are at least one selected from the group consisting of fibers of side fabric for down, coats, blousons, windbreakers, blouses, dress shirts, skirts, slacks, gloves, hats, mattress sheets, mattress covers, curtains, and tents.

5. A method for producing a water-repellent textile product, the method comprising a step of treating fibers with a treatment liquid including the water repellent agent composition according to claim 1 .

6. The method for producing a water-repellent textile product according to claim 5 , wherein the fibers are at least one selected from the group consisting of fibers of side fabric for down, coats, blousons, windbreakers, blouses, dress shirts, skirts, slacks, gloves, hats, mattress sheets, mattress covers, curtains, and tents.

7. A method for producing a water-repellent textile product, the method comprising a step of treating fibers with a treatment liquid including the water repellent agent composition according to claim 2 .

8. The method for producing a water-repellent textile product according to claim 7 , wherein the fibers are at least one selected from the group consisting of fibers of side fabric for down, coats, blousons, windbreakers, blouses, dress shirts, skirts, slacks, gloves, hats, mattress sheets, mattress covers, curtains, and tents.

9. A method for producing a water-repellent textile product, the method comprising a step of treating fibers with a treatment liquid including the water repellent agent composition according to claim 3 .

10. The method for producing a water-repellent textile product according to claim 9 , wherein the fibers are at least one selected from the group consisting of fibers of side fabric for down, coats, blousons, windbreakers, blouses, dress shirts, skirts, slacks, gloves, hats, mattress sheets, mattress covers, curtains, and tents.

11. The method for producing a water-repellent textile product according to claim 9 , wherein after treating the fibers with the treatment liquid, the fibers are heat-treated at 110° C. to 180° C.
