Description

Water-based UV (ultraviolet) curing ink, preparation method and 3D (three-dimensional) pattern fabric using ink

Technical Field

The invention relates to the field of textiles, in particular to water-based UV (ultraviolet) curing ink, a preparation method and a 3D (three-dimensional) pattern fabric using the ink.

Background

The 3D printing technology is present in the mid-90 s of the 20 th century and is actually the latest rapid prototyping device using technologies such as photocuring and paper lamination. The printing machine is basically the same as the common printing working principle, the printing machine is filled with liquid or powder and other printing materials, the printing materials are overlapped layer by layer under the control of a computer after being connected with the computer, and finally, a blueprint on the computer is changed into a real object. This printing technique is called a 3D stereoscopic printing technique.

At present, 3D printing patterns on fabrics by adopting polyurethane is a trend. The method has simple operation process, and the formed 3D pattern is fine and refined, has bright color, can be customized individually, and is particularly suitable for high-grade customized or limited edition shoe upper materials. However, this method has disadvantages that the bonding force between the polyurethane and the fabric surface is weak, and the 3D pattern of the polyurethane is easily released from the fabric surface.

In patent CN1817981A, a nano-pigment type inkjet printing ink for textiles and a preparation method thereof are disclosed. The ink consists of pigment microcapsules, self-crosslinking polymer micro-latex, deionized water, a water-soluble organic solvent, a preservative, a humectant, a surfactant and a pH regulator. According to the method, the fabric needs to be thermally baked after being printed, and the fabric can be lost in the thermal baking process.

In patent CN106380933A, a printable aqueous polyurethane 3D gold oil or 3D ink is disclosed, which prints a pattern with a certain thickness on a textile. The method adopts a mode of improving the polyurethane raw material, and increases the problems of weak adhesive force and easy shedding from the surface of the fabric. However, through research and test, when the temperature of the day is as low as 15 ℃, the adhesion of the pattern on the surface of the fabric is reduced, and the pattern is also stripped.
