Allergen reduction-processing agent for fibrous product
Provided is an allergen reduction-processing agent capable of giving an allergen reducing effect to a fibrous product while restraining whitening, and chalk marks. As chemical agents having an allergen-restraining effect, a zirconium based compound and a sulfonyl group-containing aromatic compound are used. An aqueous dispersion containing these components is used as an allergen reduction-processing agent for processing a fibrous product. The ratio by weight of the zirconium based compound to the aromatic compound is preferably 1 to 6:0.05 to 1.5.
1. An agent for application to a fibrous product, the agent being an aqueous dispersion which contains:
(a) zirconium phosphate and a polymer containing an aromatic sulfonium salt, in which the ratio by weight of the former to the latter is 1 to 6:0.05 to 1.5;
(b) a polyester resin; and
(c) at least one selected from the group consisting of n-butylcellosolve, t-butylcellosolve, n-propylcellosolve, and isopropyl cellosolve as a solvent for dispersing the polyester resin.
2. The agent according to claim 1 , in which the zirconium phosphate and the polymer containing the aromatic sulfonium salt contained in the aqueous dispersion are each in a granular form.
3. The agent according to claim 1 , in which the content of the total of the zirconium phosphate and the polymer containing the aromatic sulfonium salt in the aqueous dispersion is from about 0.4% to 5.5% by weight.
4. The agent according to claim 1 , in which the content of the polyester resin in the aqueous dispersion is from about 0.1% to 3% by weight.
5. The agent according to claim 1 , in which the ratio by weight of the polyester resin to the solvent is 1:0.1 to 1.5.
6. A polyester fibrous product, comprising:
zirconium phosphate, a polymer containing an aromatic sulfonium salt and a polyester resin adhering to the fibrous product; and
the ratio of the zirconium phosphate to the polymer containing the aromatic sulfonium salt being 1 g/m 2 to 6 g/m 2 :0.05 g/m 2 to 1.5 g/m 2 .
