Description

Dryer for Digital Printing {{Dryer For Digital Textile Printing}

The present invention relates to a dryer used for digital printing, and more specifically, to increase dye adhesion through a drying process after fabric printing, and to be easily attached and used during printing on a digital printing line, which is a small quantity production line of a large variety of products, due to easy movement and handling. It relates to a digital printing dryer that can only.

In general, digital textile printing is a method of applying inkjet printing technology to printing.

The digital printing method using the inkjet enables the factory automation by the development of CAD / CAM using a computer, the micro expression as shown in the picture, and the design synthesis, color conversion, shape correction, etc. As it is possible to produce, it can satisfy the needs of the modern consumer, whose personality is important, and also has the advantage of coping organically with the supply and demand market.

In addition, it is one of the printing methods that the technology is rapidly developing in the printing industry recently in that it can not only save energy, but also have no problem of causing environmental pollution, such as no waste water treatment because there is no generation of remnants.

Inkjet printing is divided into three processes, which are roughly classified into a pretreatment process, a printing process, and a posttreatment process.

The pretreatment process is a process for preventing bleeding or flow phenomenon and improving color development and overall fastness when the ink material is actually treated by the liquid composition on the fiber material. In the general printing process, a color arc including dyes and auxiliaries and various printing aids is used, whereas inkjet printing uses only dyes for printing, and thus a process of pretreatment of auxiliaries and other printing aids to fibers is required. The characteristics of the inkjet ink are due to the inkjet printing method by spraying ink, and when the pretreatment process is omitted, the quality of the printing material is poor and the value as a product is lost.

The printing process is an actual inkjet printing process in which ink is sprayed and dyed based on a digitized signal.

The post-treatment step refers to inkjet printing, drying, heating, drying, and then washing with water and drying.

In the inkjet printing process, the only digitized part is the printing process, and the pre- and post-treatment processes before and after the process are still performed in the analog manner.

Currently, small and medium-sized printing companies in Korea want to use digital printing system with order-based production concept, but they are feeling burden on operating cost, and for producing small quantity of high value-added products such as design development and product development. The digital printing system is not used.

In addition, the printing production using the digital printing system is the main work of less than 100yds, and there is no post-processing and post-processing equipment developed exclusively for the digital printing system, the post-treatment process according to the mass production line.

Post-treatment of less than 100 yds using a 10,000 yds facility is reluctant to accept small orders from existing printing companies, causing labor and energy waste.

When fabrics produced by the digital printing method are processed using the existing mass printing after-treatment facilities, the dyes used in the digital printing method can be applied to the bulk equipment and processing technology tailored to the characteristics of the dyes and preparations used in the existing printing process. As it is applied without considering the preparation characteristics, it causes many problems such as deterioration of color development, deterioration deterioration, damage to fabric and fastness of fastness, and even after the product produced by the excellent digital printing method, post-treatment and post-processing are properly performed. If this is not done, the quality of the final product will deteriorate and the value of the product will fall.

In addition, since most printing companies produce only specialized items, it is inefficient in terms of time and energy consumption to be used in combination with a production line of a multi varieties and a small quantity of digital printing methods.

In the case of mass production, it is desirable to use a digital printing method for the production by the digital printing method while utilizing existing post-processing and post-processing facilities.

This is because digital printing does not form a condition where ink can be dried sufficiently after printing the fabric unlike the general printing, and this causes an increase in unfixed dye components, defects such as dye printing, and deterioration of the optimal printing quality. Will result.

Therefore, the present invention is to solve the problems as described above, the purpose is to increase the dye adhesion improvement rate through the drying process after the output of the fabric, and easy to move and handle easily attached to the digital printing line, which is a small quantity production line of various types To provide a digital printing dryer for use only.
