Abstract

Method for inkjet textile printing comprising a printing step for printing an aqueous pigment ink on a specifically pretreated portion of a textile fiber product by an inkjet process, wherein said specific pretreatment is performed by applying at least: (A) a quaternary ammonium salt type cationic surfactant represented by the formula (1) below, and (B) a block isocyanate compound to the entire textile fiber product or a required portion thereof, and said aqueous pigment ink comprises at least a pigment, an aqueous liquid as a solvent or dispersion medium, and: (C) a water-soluble dispersing agent having a crosslinking property, (D) a self-emulsifying type urethane resin, and (E) a block isocyanate compound. [Two of R1 to R4: alkyl having 8 to 18 carbon atoms; the remaining two: methyl or ethyl; X−: anion.]

Dependent claims

A method for inkjet textile printing comprising a pretreatment step for performing a pretreatment on a textile fiber product and a printing step for printing an aqueous pigment ink on the pretreated portion of the textile fiber product by an inkjet process,

wherein said pretreatment is performed by applying at least:
(A) a quaternary ammonium salt type cationic surfactant represented by formula (1) below, and
(B) a block isocyanate compound to the entire textile fiber product or a required portion thereof,
and said aqueous pigment ink comprises at least a pigment, an aqueous liquid as a solvent or dispersion medium, and:
(C) a water-soluble dispersing agent having a crosslinking property,
(D) a self-emulsifying type urethane resin, which is not water-soluble, and
(E) a block isocyanate compound
in formula (1), two of R1 to R4 mutually independently represent an alkyl group having 8 to 18 carbon atoms, the remaining two mutually independently represent a methyl group or an ethyl group, and X− represents an anion.
