How to Guarantee Dye Brightness When Using Small Plates

At the time of playing a small version, the bright color can't reach his sample. It is a 3068 fine cloth. It looks like a fine cloth of 20, three colors, a deep, medium, and light three-colored orange. It is bright with red light. We used K-type, B-type, and a new type of SCN. However, the results are not satisfactory. Do you not know who has a better solution?

First analyze whether the sample is active, with bleaching or insurance powder stripping test. Look at the back of the fabric penetration and the original is the same, deep medium and light three colors are imprint it? Compare the brightness changes before and after stamping. Do it after analyzing the sample. In addition, if the brightness can not be achieved, the active coating can be used for printing paste or paint anti-printing process.

In general, it is normal for high-yarn fabrics to have a color that is not bright or deep in the fabric of a low-count yarn, because there is an abnormality in the “specific surface area”. However, the difference between the 20S and the 30S in the proof fabrics and the sample fabrics should not be too great, as they try to find the reasons from the following points:

1, look at the background color cloth is not added fluorescent brightener, brightening cloth color is bright.

2, the dye cause, this must first look at whether the sample is a fluorescent dye, and secondly we must pay attention to the monochrome dye hue to be pure, can not bring a little blue or blue light, if any, must be gray no doubt.

3, the difference in the pre-treatment, such as pre-treatment using hot boiled bleaching process to beat the color than the cold-rolled heap to be bright.

4. Differences in cotton, for example, the billet of Pakistan is brighter than the domestic billet due to the strong maturation of sunlight.
