Description

TECHNICAL FIELD [0001] The present invention relates to a surface treatment agent for natural textile yarn and a digital textile printing (DTP), a method for producing the surface treatment agent, and a natural textile fiber printed matter using the surface treatment agent fiber yarn, the method for making this surface treatment agent and natural fiber yarn,

The present invention relates to a surface treatment agent for natural textile yarn and a digital textile printing (DTP), a method for producing the surface treatment agent, and a natural fiber yarn printed matter using the surface treatment agent. More particularly, , Organic pigments, direct dyes, acid dyes, reactive dyes and dispersed dyes, which are printed through the gravure printing apparatus and DTP printer of the present invention. The dye is bonded, adsorbed, and coupled to the fabric to increase the binding force to prevent discoloration and discoloration, and it is also environmentally friendly and harmless to the human body as well as improving color fastness, wash fastness, light fastness, dry friction friction durability, The present invention relates to a method for realizing the present invention and DTP without deteriorating the physical properties of the yarn.

Techniques for dyeing a variety of natural fiber yarns such as cotton, hemp, ramie, denim, wool, rayon, etc. are being digitally evolved from analog to digital.

As a result, complex processes are simplified to improve quality and work environment.

The dyeing process for applying color to textile materials can be divided into a dyeing process for applying the same color to the entire fabric, and a printing process for partially expressing a specific pattern and color.

In particular, printing, also called printing, is widely used for applications such as clothing, interior use, and embroidery (embroidery).

Conventional methods of printing a specific pattern on a natural fiber yarn include a screen printing method in which an ink is applied onto a stand frame with a silk fiber inserted into the frame, a printing method in which the ink is partially colored by a printing paste, It is mainly used.

When a specific pattern is printed on a natural fiber yarn by the screen printing method or the printing method, a number of processes are performed to complicate the process, and not only the cost of the natural fiber yarn is increased, but also sharpness and precision are lowered when a fine pattern is printed Thereby causing environmental pollution.

The problem of the screen printing method or the printing method is that since the adhesion of the disperse dye is weakened and the chemical structure between the yarn and the dye is different, color fading or discoloration occurs during washing and many problems are caused by contamination and dye transfer, . ≪ / RTI >

Consumers prefer fabrics of various colors and the cycle of fashion tendency is getting shorter and faster, so it is required to improve the printing technology so that various designs can be easily expressed.

It is DTP that emerged according to this trend. DTP is a next-generation printing technology that can digitize the entire process from fiber design to final material production, replacing the complex process of existing printing.

Thus, Korean Patent Laid-Open Publication No. 10-2012-0039919 proposes a method for producing a nano-scale natural ink for DTP using natural dyes and a digital printing method.

Unlike the conventional printing method, such a DTP can freely implement a color without restriction of the color frequency, and it is also possible to express a gradation or a real image.

However, there is a problem in that when the output is actually performed using the method of the above patent, the printing quality is poor due to the use of natural dyes.

Further, since a natural dye is used, the unit cost of the dye is increased, and the color of the natural ink is poor.

U.S. Patent No. 9453301 has proposed an in-line digital printing system for textile materials.

Such an inline digital printing system can simplify the process and is suitable for mass production.

However, the adsorptivity of the pretreating agent used is not expected to be significantly improved.
