Oxford cloth printing is a process in which various dyes or pigments are mixed into printing pastes and applied locally on Oxford cloth to obtain various patterns and patterns. Yes, it’s partial shading. In order to prevent the bleeding of the dye solution and ensure the clarity and fineness of the pattern, color paste must be used for printing. Gray fabric cannot be used directly for printing. It must be bleached and refined to remove impurities and weaving slurry, as well as wax, grease, etc. on the fibers to ensure the quality of printing and the fastness of coloring. In addition, due to the presence of paste in the color paste, the process of dyeing the fibers with dyes is more complicated than dyeing. Generally, steaming or other color fixing methods are required to promote the dyeing after dye printing; printing Oxford cloth also needs to be fully carried out. Washing and soaping to remove paste or floating color, improve hand feel, bright color and fastness.
There are three types of Oxford cloth printing: direct printing, discharge printing, and resist printing.
Direct printing: A printing method that directly prints printing color paste on Oxford cloth to obtain various patterns. It is characterized by simple printing process, suitable for all kinds of dyes, and widely used. Discharge printing: A method in which Oxford cloth is dyed first and then printed. The printing paste contains a chemical substance (called a discoloration agent) that can destroy the chromogenic group of the ground color dye and make it decolorized. After printing, appropriate post-processing will destroy the ground color dye at the printing place, and finally from When the Oxford cloth is washed off, the printed area will turn into a white pattern, becoming a white-out printing; if the printing paste containing a discharge agent also contains a dye that is not destroyed by the discharge agent, it will destroy the ground color dye. At the same time, the color paste can only be dyed with the dye, so that the printed area can obtain colored patterns, which is called color discharge printing. Discharge printing has rich colors, clear outlines, detailed patterns and bright colors. However, the choice of ground color dyes is subject to certain restrictions, and the printing cycle is long and the printing cost is high. Resist dyeing printing: The processing method of printing and dyeing first. The printing paste contains chemical substances (anti-dyeing agents) that can destroy or prevent the dyeing of ground color dyes. The ground color dyes cannot be dyed in the printing area. After washing, the printing area will appear white pattern, which is called anti-white printing; if it is While preventing whitening, the printing color paste also contains dyes that do not interact with the dye resist. When the ground color dye is dyed, the dye in the color paste dyes the printed area, and the printed area will obtain a colored pattern, which is called color. Anti-printing. The patterns obtained by resist printing are generally not as fine as discharge printing, but there are more types of ground color dyes suitable for resist printing than the former.
