Abstract

A processing liquid composition of the present disclosure subjected to textile printing and which is used by being attached to a fabric including fibers having a hydroxyl group, includes an oxazoline group-containing polymer and an aromatic carboxylic acid. An oxazoline value of the oxazoline group-containing polymer is preferably 100 or more and 600 or less.

First claim

What is claimed is:

1. A processing liquid composition subjected to textile printing and which is used by being attached to a fabric including fibers having a hydroxyl group, the composition comprising:
an oxazoline group-containing polymer; and
an aromatic carboxylic acid.

2. The processing liquid composition according to claim 1 , wherein an oxazoline value of the oxazoline group-containing polymer is 100 or more and 600 or less.

3. The processing liquid composition according to claim 1 , wherein a content ratio of the oxazoline group-containing polymer in the processing liquid composition is 1.0% by mass or more and 10.0% by mass or less.

4. The processing liquid composition according to claim 1 , wherein a content ratio of the aromatic carboxylic acid in the processing liquid composition is 0.1% by mass or more and 20.0% by mass or less.

5. The processing liquid composition according to claim 1 , wherein the aromatic carboxylic acid is one or more selected from the group consisting of benzoic acid, 1-naphthalene carboxylic acid, 2-naphthalene carboxylic acid, and salts thereof.

6. The processing liquid composition according to claim 1 , wherein the oxazoline group-containing polymer is a resin having a styrene-acrylic structure.

7. The processing liquid composition according to claim 1 , wherein a glass transition temperature of the oxazoline group-containing polymer is 0° C. or higher.

8. The processing liquid composition according to claim 1 , wherein 0.1≤XP/XA≤40, here a content ratio of the oxazoline group-containing polymer in the processing liquid composition is XP [% by mass] and a content ratio of the aromatic carboxylic acid in the processing liquid composition is XA [% by mass].

9. A composition set comprising:
the processing liquid composition according to claim 1 ; and
an ink jet dye textile printing ink composition containing a dye and water.

10. The composition set according to claim 9 , wherein the dye is a disperse dye.

11. A processing method comprising:
a processing liquid attaching step of attaching the processing liquid composition according to claim 1 to a fabric including fibers having a hydroxyl group.

12. A textile printing method comprising:
an ink composition attaching step of applying an ink jet dye textile printing ink composition containing a dye and water to an intermediate transfer medium by an ink jet method to form an image; and
a transfer step of heating the intermediate transfer medium and a processed fabric, which is obtained by carrying out processing using the processing liquid composition according to claim 1 on a fabric including fibers having a hydroxyl group, in a state where the intermediate transfer medium and the processed fabric face each other such that the image is transferred to the processed fabric.
