Description

Ink composition for digital textile print

The present invention relates to an ink composition for digital textile printing.

Dyeing refers to the coloring of pigments, such as dyes and pigments, in pigmented materials (threads, fabrics, leather, etc.) such as textiles. This is done by dividing part or most of the dyes and dyes with different colors.

Digital textile printing is a new dyeing technique widely used in the textile industry. All processes from design to final output can be computerized using computer to standardize and simplify the way of working. This is an easy advantage.

However, the presently used digital textile printing (DTP) ink has a problem that it is fixed to the fiber after printing but does not develop color, and transfer ink has a good color development but poor washing fastness in cotton, nylon, etc. There was this.

The present invention has been made in order to solve the problems of the prior art as described above, unlike the existing digital textile printing ink, color development occurs well, and provides a digital textile printing ink composition excellent in wash fastness on cotton, nylon, etc. The purpose is.

As an example for achieving the above object, the ink composition for digital textile printing of the present invention is ----- pigment-to-wt%, ---- dye-to-wt%, humectant -To-weight%, anti-blocking agent-to-weight%, leveling agent-to-weight%, volatile agent-to-weight%, surfactant-to-weight%, antifoaming agent -To-wt%, polyurethane-based dispersant-to-wt%, isocyanate-based curing agent-to-is characterized by comprising a balance and water.

Hereinafter, the ink composition for digital textile printing of the present invention will be described in detail for each component.

First, the ink composition for digital textile printing of the present invention is characterized by including a pigment and a dye at the same time.
