Abstract

A cationizing agent for cationizing a cloth prior to the firm fixing of water-insoluble particles onto the cloth, said cationizing agent comprising a polymer having a constituent unit (a1) derived from a vinylamine monomer represented by formula (1). (In the formula, R 1 represents a hydrogen atom or a methyl group.)

First claim

The invention claimed is:

1. A method for firmly fixing water-insoluble particles onto a fabric, comprising:
cationizing the fabric by firmly fixing a cationizing agent to the fabric, wherein the cationizing agent comprises a polymer comprising a constituent unit (a1) derived from a vinylamine monomer represented by formula (1); and
firmly fixing water-insoluble particles to the fabric by bringing the water-insoluble particles into contact with the fabric after the cationizing

where R 1 represents a hydrogen atom or a methyl group.

2. The method according to claim 1 , wherein the fabric is formed from at least one selected from the group consisting of a cotton, an acrylic fiber, a polyester fiber, an acetate fiber and an aramid fiber.

3. The method according to claim 1 , wherein the fabric is a suede-like fabric comprising ultrafine fibers.

4. The method according to claim 1 , wherein the fabric has a zeta potential of −100 mV to −1 mV.

5. A method for producing a dyed material, comprising:
cationizing a fabric by firmly fixing a cationizing agent to the fabric, wherein the cationizing agent comprises a polymer comprising a constituent unit (a1) derived from a vinylamine monomer represented by formula (1); and
firmly fixing a pigment to the fabric to dye the fabric, by bringing the pigment into contact with the fabric after the cationizing

where R 1 represents a hydrogen atom or a methyl group.

6. The method according to claim 5 , wherein the pigment is at least one selected from the group consisting of an azo-based pigment, a phthalocyanin-based pigment, an anthraquinone-based pigment, a quinacridone-based pigment, a perylene-based pigment, a perinone-based pigment, a dioxazine-based pigment, a quinophthalone-based pigment, a fluorescent pigment, carbon and titanium oxide.

7. A fabric, comprising
a cationizing agent comprising a polymer comprising a constituent unit (a1) derived from a vinylamine monomer represented by formula (1)

where R 1 represents a hydrogen atom or a methyl group; and
water-insoluble particles.
