Description

REDUCTION COLOR DEVELOPMENT APPARATUS FOR CELLULOSE KNITTED FABRIC AND METHOD OF REDUCTION COLOR DEVELOPMEMT USING THE SAME}

The present invention relates to a reduction coloring apparatus using batt printing cellulose knitted fabric and a method of reducing coloring using the same. More specifically, after printing the cellulose knitted fabric with a bait dye, the process of reducing, increasing and oxidizing is performed. The present invention relates to a method of dyeing and dyeing, which prevents edge curling, prevents thinning and bleeding, and enables efficient reduction of coloration and oxidative fixation through improved conditions and continuous linkage between processes.

In general, in dyeing the salts such as cellulose fiber fabrics, a lot of batt (VAT) dyes and the like are used. In the printing of the to-be-printed dye using such a bait dye, the dye is padded, printed, and printed on the dye to be printed (dyed) by a process such as reduction, heating and oxidation.

Specifically, in the printing of the dye, the dye is first imprinted with the dye, and then a reducing process (reducing color development) to convert the insoluble dye particles into water solubility using a reducing agent to dye the dye, and high dyeing and stable color development. For this purpose, a heating step of applying high temperature heat and an oxidation step (oxidation fixation) of converting the water-soluble dye particles into insoluble dye particles and fixing them using an oxidizing agent are carried out. Thereafter, soaping is performed to remove undyed residual dye, followed by washing with water and drying.

For example, Japanese Patent Application Laid-Open No. H7-279064, Republic of Korea Patent No. 10-0346239, Republic of Korea Patent No. 10-0530571, Republic of Korea Patent No. 10-1002294, and the like have been presented.

However, due to problems such as delays between processes and linkage between processes in the process of the above process, deterioration of thinness (definition of boundaries of color lines after color development) and bleeding phenomenon (stamping) It is caused by the phenomenon that the area is spread to the other stamped area, and the color is different from the original color or has a different pattern), and there are many difficulties such as poor reproducibility. This problem is most often generated in the reduction process of the above-listed process, and may occur frequently even when the linkage between the processes is not smooth.

Despite having many problems in the above process, the reason why the bat printing process is attracting attention is the reason why the natural high fastness of the bat dye is the biggest. That is, bart dyes have strengths in color fastness that have a higher performance of 1.5 to 2.5 grades or more than the fastnesses generally used in reactive dyes, acid dyes and disperse dyes. It is unique in terms of daylight fastness (tolerance to sunlight). In other words, when the daylight fastness of the reactive dye group generally used for cotton dyeing in view of the 'grade 3' level, the daylight fastness of the bat dye group is determined to be 'grade 5-6' level. Due to these characteristics, the bait dye is mainly applied to high-quality outerwear or military uniforms with high exposure to sunlight.

However, as described above, in the conventional dyeing process, the thinness decreases and the bleeding phenomenon occurs. In addition, the steaming process should be performed immediately after the reduction process, and the conventional dyeing process causes rapid dye oxidation by contact with oxygen in the air after reduction, resulting in irregular reduction and coloring of the chlorine, resulting in poor commerciality. Accordingly, most of the bat-dyed products currently on the market are obtained by post-processing in the salted water.

In particular, the conventional dyeing process is difficult to continuity and link between each process due to the occurrence of edge curl phenomenon. Such edge curling occurs mainly in the heating process. That is, as described above, a reduction process (reduction color development) is followed by a vaporization process in which high temperature heat is applied to the salts for high dyeing and stable color development, wherein the edges of the salts are dried by the high temperature ( Curling) occurs, which not only degrades the quality of the product but also makes the continuous process difficult. In particular, in the case of the Knit family, edge curling occurs badly.

Knit products are more affected by tension in processing and processing than fabric products, and the quality of the products is remarkably poor when high tension is applied. In general, in the dyeing process of the knit product line, the overfeed control and the speed control in each process are an important part, and in particular, the tensioning process must be accompanied. At this time, in the case of the knit product, when the tension is applied to prevent the edge curling, the quality of the product is significantly lowered and the merchandise is inferior.

Therefore, in the printing process using the bart dye, etc., it is necessary to increase the heat within the shortest time in order to minimize the decrease in fineness and the bleeding (bleeding) phenomenon and to minimize the contact with oxygen after the reduction. Above all, it is necessary to prevent edge curling in order to allow continuous processing. However, the dyeing process according to the prior art has a problem that it is difficult to apply a continuous process equipment due to the lack of technical measures to prevent the edge curling phenomenon. This is especially the case for the knit product line, which has more difficulties than the fabric line in the process.

The reducing liquid padding unit 200 is not limited as long as the reducing solution A is immersed and padded in the reducing liquid to realize reducing color development. The reducing liquid padding unit 200 may be continuous or batch type. Preferably, the reducing liquid padding unit 200 may be a continuous type in which the dye (A) is immersed and padded in the reducing liquid in a continuous process after dyeing. That is, the chlorine A may be continuously supplied from the chlorine supply unit 100 to the reducing liquid padding unit 200 along the guide roll R.

Referring to FIG. 2, according to a preferred embodiment of the present invention, the reducing solution padding unit 200 is a reducing solution supply tank 210 in which a reducing solution is accommodated, and a reducing solution is immersed in a reducing solution and padded with a reducing solution. It is preferable to include a liquid immersion padder 220, and a pickup adjusting means 230 for adjusting the pickup ratio (ie, the amount of padding) of the reducing liquid that is padded in the chlorine (A).

As a result, continuous dyeing processing is possible for the knit product line requiring tension. That is, in the case of the knit product line, as described above, when a high tension is applied in the longitudinal direction or the width direction to prevent the edge curling, the quality of the product is remarkably deteriorated and the commerciality is inferior.
