Abstract

A pretreatment agent for inkjet textile printing and an inkjet textile printing method that can realize improvement in productivity, cost reduction, energy saving, and space saving while ensuring ink permeation and resistance to color bleeding are provided. The pretreatment agent for inkjet textile printing of the present invention contains an N-vinylformamide-based cationic polymer and an antifoaming agent.

First claim

What is claimed is:

1 . A pretreatment agent for inkjet textile printing comprising:
an N-vinylformamide-based cationic polymer and an antifoaming agent.

2 . The pretreatment agent for inkjet textile printing according to claim 1 , wherein a content ratio (mass ratio) of the antifoaming agent to the N-vinylformamide-based cationic polymer in the pretreatment agent for inkjet textile printing is 2.0 or more.

3 . The pretreatment agent for inkjet textile printing according to claim 1 , wherein a content ratio (mass ratio) of the antifoaming agent to the N-vinylformamide-based cationic polymer in the pretreatment agent for inkjet textile printing is 4.0 or less.

4 . The pretreatment agent for inkjet textile printing according to claim 1 , wherein the antifoaming agent contains one or more types selected from the group consisting of an alcohol-based antifoaming agent and a fatty acid derivative-based antifoaming agent.

5 . The pretreatment agent for inkjet textile printing according to claim 1 , further comprising a color deepening agent.

6 . The pretreatment agent for inkjet textile printing according to claim 5 , wherein the color deepening agent has compatibility with the N-vinylformamide-based cationic polymer.

7 . The pretreatment agent for inkjet textile printing according to claim 5 , wherein the color deepening agent contains one or more types selected from the group consisting of N-alkylolamide and glycol ethers.

8 . The pretreatment agent for inkjet textile printing according to claim 1 , further comprising a pasting agent.

9 . The pretreatment agent for inkjet textile printing according to claim 8 , wherein the pasting agent includes a pasting agent having compatibility with the N-vinylformamide-based cationic polymer and being nonionic or anionic.

10 . The pretreatment agent for inkjet textile printing according to claim 8 , wherein the pasting agent contains one or more types selected from the group consisting of methyl cellulose, hydroxypropyl methyl cellulose, hydroxyethyl cellulose, and guar gum.

11 . The pretreatment agent for inkjet textile printing according to claim 8 , wherein the pasting agent further contains montmorillonite.

12 . The pretreatment agent for inkjet textile printing according to claim 1 , wherein the N-vinylformamide-based cationic polymer contains one or more types selected from the group consisting of polyamidine and polyvinylamine.

13 . The pretreatment agent for inkjet textile printing according to claim 1 , wherein a content of N-vinylformamide-based cationic polymer is 0.6% by mass or more and 1.4% by mass or less with respect to 100% by mass of a total mass of the pretreatment agent for inkjet textile printing.

14 . A pretreatment agent for inkjet textile printing comprising a cationic polymer and an antifoaming agent, wherein a cationic degree of the cationic polymer is 5.0 meq/g or more and a viscosity of the cationic polymer is 100 mPa·s or more.

15 . An inkjet textile printing method comprising pretreating a textile with the pretreatment agent for inkjet textile printing according to claim 1 and performing inkjet printing on a pretreated area of the pretreated textile without drying the pretreated textile.

16 . The inkjet textile printing method according to claim 15 , wherein ink used in the inkjet printing is a disperse dye.

17 . An inkjet textile printing method comprising:
pretreating a textile with a pretreatment agent for inkjet textile printing; and performing inkjet printing on a pretreated area of the pretreated textile without drying the pretreated textile, wherein the pretreatment agent for inkjet textile printing contains an N-vinylformamide-based cationic polymer.
