Abstract

A method for manufacturing printed textiles includes the steps of: a) inkjet printing an image onto a textile substrate with one or more inkjet printing liquids containing thermally reactive composite resin particles in an aqueous medium; and b) fixing the inkjet printed image by applying directly and/or indirectly a heat treatment to the image; wherein the thermally reactive composite resin particles contain at least one thermal cross-linker and at least one polymeric resin containing functional groups suitable for reacting with the thermal cross-linker.

First claim

The invention claimed is:

1. A method for manufacturing printed textiles, the method comprising the steps of:
inkjet printing an image onto a textile substrate with one or more inkjet printing liquids including thermally reactive composite resin particles in an aqueous medium; and
fixing the image by applying an indirect heat treatment using infrared light and/or by applying a direct heat treatment by heat convection or heat conduction to the image; wherein
the thermally reactive composite resin particles include at least one thermal cross-linker and at least one polymeric resin including functional groups suitable for reacting with the at least one thermal cross-linker; and
the at least one polymeric resin is an amphiphilic polymer including:
a hydrophobic segment that is styrene based, acrylate based, vinyl ester based, vinyl acetal based, or combinations thereof; and
a hydrophilic segment that includes at least one functional group selected from the group consisting of a sulfonic acid or salt thereof, a carboxylic acid or salt thereof, a —(CH 2 CH 2 O) n —H group wherein n represents an integer from 2 to 25, and a C2 to C12 aliphatic group substituted by hydroxyl groups wherein a carbon on hydroxyl ratio is 2 or less.

2. The method for manufacturing printed textiles according to claim 1 , wherein the at least one thermal cross-linker includes at least one functional group selected from the group consisting of an epoxide, an oxetane, an aziridine, an azetidine, and a blocked isocyanate.

3. The method for manufacturing printed textiles according to claim 1 , wherein the image includes at least one color pigment.

4. The method for manufacturing printed textiles according to claim 2 , wherein the image includes at least one color pigment.

5. The method for manufacturing printed textiles according to claim 1 , wherein the step of fixing the image includes using infrared light.

6. The method for manufacturing printed textiles according to claim 1 , wherein the step of inkjet printing further includes inkjet printing aqueous inkjet printing liquids including a color pigment but no thermally reactive composite resin particles.

7. The method for manufacturing printed textiles according to claim 1 , wherein the textile substrate is selected from the group consisting of cotton textiles, silk textiles, flax textiles, jute textiles, hemp textiles, modal textiles, bamboo fibre textiles, pineapple fibre textiles, basalt fibre textiles, ramie textiles, polyester based textiles, acrylic based textiles, glass fibre textiles, aramid fibre textiles, polyurethane textiles, high density polyethylene textiles, and mixtures thereof.

8. The method for manufacturing printed textiles according to claim 1 , wherein the at least one thermal cross-linker includes a blocked isocyanate compound.
