It may be due to the use of too much thinner, especially the poor compatibility of thinner and ink, which causes color bleeding during PP textile printing. It may be that there is color seeping on the edge of the printed image and text, which is a common phenomenon, so don't worry too much. It can be solved by ordinary methods. It may be caused by the selection of dyes in the ink, or it can be said that it is caused by the improper matching of pigments. We can deal with the problems in this link according to the situation, and pay attention to the details in this link.
Flat screen printing. The printing mould is a polyester or nylon screen (pattern) fixed on a square frame with hollow patterns. The pattern on the pattern plate can pass through the color paste, and the mesh without pattern can be sealed with a polymer film. When printing, the pattern is pressed against the fabric, and the color paste is placed on the pattern. The scraper is used to repeatedly scrape and press the color paste to reach the fabric surface through the pattern. Flat screen printing has low production efficiency, but wide adaptability and flexible application, suitable for small batch and multi variety production. Water slurry printing of bag webbing.
Customized Cotton ribbon Manufacturer The second part of our knowledge of printing types. The printing of luggage webbing is a kind of process that I like very much. The first part of what I just said is followed by the second part, which is also very interesting. Let's enjoy it together. Glue printing of luggage webbing. After the emergence and wide application of glue paste in water paste, due to its excellent coverage, it can also print any light color on dark clothes, and has a certain gloss and three-dimensional sense, making ready to wear clothes look more high-end, so it is rapidly popularized, and almost every piece of printed T will use it.
There are two primary methods for coloring, one is to apply it to a wide range of dyeing (conventional dyeing), and the first is to treat it in chemical dye solution. The other method is to use paint to make the paint into tiny insoluble colored particles to stick to the fabric (dyeing of fibrous material stock solution is not included). Acid dyes are mostly suitable for protein fiber, nylon fiber and silk. It is characterized by beautiful color, poor washing degree and excellent dry cleaning degree. It is widely used in natural dead dyeing.
Clear drawings within parameters: clear the drawings within the set range of longitude and latitude. Multiple maps to one map: insert multiple maps into one map in the longitudinal direction. One manufacturing to multiple manufacturing: turn in one drawing and disassemble it into multiple pieces in the longitudinal direction. Graph merging: after multiple graphs are handed over and inserted into one (that is, multiple weaving turns to one manufacturing), the whole warp yarn with one upper and lower weave is deleted. Computer jacquard webbing drawing sequence: analyze the weave rule of the jacquard webbing, draw all the "high" parts of the text or pattern in a cycle according to the weave rule that has been analyzed and determined and the actual fabric, and then draw the "high" parts of the background color (color other than text or pattern) in a cycle according to the weave rule. After all the "high" parts are drawn, The "low" part of the pattern and bottom is drawn according to the analyzed organization rule until the drawing is completed.
Causes of bleeding. Some customers will customize the printing, but the PP fabric manufacturers sometimes have color bleeding when printing the PP ribbon, so the manufacturers should pay attention to the reasons when printing. Only by understanding these reasons can we reduce the occurrence of various conditions in the future use. What are the reasons for color bleeding when printing? There is dirt on the surface of the machine during printing. Cleaning up during production can reduce these problems.
