Description

Method for preparing removable digital textile printed tricot sheet {Method for preparing removable digital textile printed tricot sheet}

The present invention relates to a method of manufacturing a releasable digital printing tricot sheet. Further, the present invention relates to a re-peelable tricot sheet produced by the above method.

Fabrics and knitted fabrics are the most basic things when making fabrics or fabrics. The fabric refers to a fabric manufactured through a weaving process, and a knitted fabric refers to a fabric manufactured through a knitting process. Here, the knitting can be divided into warp knit and upper knit, tricot and French correspond to warp knit, and the upper knit can be divided into circular knit and flat knit flat knit. Warp knitting means that the loop (nose, stitch) and the loop are connected in the warp direction, that is, the longitudinal direction, and warp knitting with piles formed on the surface is also called warp knitting velvet. The upper piece means that the loops are connected in an upward direction, that is, a horizontal direction. Tricot is a type of warp knitting, which means that the guide bar used when knitting is coordinated into three pieces.

On the other hand, microfiber has a unique and excellent draped gloss touch appearance, and is marketed not only for clothing use, such as high-quality fabrics with a soft touch such as artificial suede, high-performance moisture-permeable waterproof fabrics, high-hygroscopic knitting cleaners, filters, and dustproof clothes, as well as industrial applications Is gradually expanding. Unlike ordinary yarns, microfibers are thin and have a three-dimensional structure with delicate fibers, and there are countless micro-spaces generated during division, causing capillary phenomenon, and a large surface area (FIG. 1). With this feature, a soft touch that is not irritating to the skin can be expressed, but the thinner the fineness, that is, the lower the denier, the greater the total surface area, so the apparent dyeing amount (K/S) decreases and You have to use a lot more dye than that.

In addition, there are differences in cross-point density, surface gloss, and surface irregularities depending on the type of tricot structure, and the difference in voids (density) due to the physical structure of the fiber may affect the sharpness and sharpness of the DTP color.

Digital textile printing technology is a technology that meets the demands of the times, such as diversification of designs, individualization of fashion, and shortening of delivery, as well as social demands for solving problems such as environmental pollution, labor intensity, and inefficiency of traditional textile printing technology. have. By using this system, it is possible to respond to short delivery times by minimizing the process, reduce fixed costs, create new printing designs by improving the ability to express various colors and patterns, and achieve marketing effects using developed networks and database systems. In addition, unlike general screen printing processes, it is an eco-friendly industry such as reducing the burden of wastewater treatment for undyed dyes and treatment agents, and is responding agilely to changes in the market. In order to use digital textile printing on fabric, the optimization of pre-treatment and printing conditions is a prerequisite for producing high-quality printing products.

In the case of bonding the fiber sheet and the adhesive sheet to be integrated with the base material, misalignment may occur during the bonding operation, or work errors such as attracting air bubbles or foreign matter may occur.

When passing through the press in this way, the image printed on the transfer paper is transferred to the fabric.

Color development and sharpness were evaluated to determine the degree of DTP color expression for microfiber tricot using aqueous transfer ink.

For the evaluation of color development, the color intensity of the four CMYK colors digitally printed on the pre-treated fabric was measured three times using CCM, and the total K/S value was calculated as an average value.

The calculation formula for the K/S value is as follows.

K/S = (1-R)2 / 2R (K: absorption coefficient, S: scattering coefficient, R: spectral reflectance)

Cyan (C) was determined by 640 nm, Magenta (M) at 520 nm, Yellow (Y) at 440 nm, and Black (K) at 600 nm wavelength.

As shown in Table 10, it was confirmed that the transfer time condition was an optimal condition at 60s.

Then, using a paper printed with CMYK ink, the transfer time was fixed at 60 s, and the transfer temperature was changed to 155°C, 160°C, 165°C, 170°C, 175°C, 180°C and 185°C, using a microfiber tricot sheet. Experimented. The K/S values were checked in each condition, and the experimental results are shown in Table 11 and FIG. 9 below.
