Graduation class is open. Every day Xiaobian will prepare fresh information and knowledge for you. Please follow us. Today Xiao Bian told everyone about the flannel printing process. 1. Printing process: flannel printing process is basically the same as general cotton cloth. At present, the commonly used process is the coating process, the pull-active process, and sometimes the ice-coating process. The anti-imprinting process and the anti-discharge process will also be adopted. 2. Requirements for semi-finished products: (1). Capillary effect, the first consideration of flannel printing is the capillary effect of the flannel print fabric , and some patterns require a deeper color. The requirements for the gray effect of the grey cloth are high, and the scouring must be used. Therefore, the alkali concentration and temperature must be increased so that the gross efficiency of the grey cloth is about 7cm/30min. However, at this time, the wax on the grey cloth is insignificant and must be processed by the waxing process. velvet. (2). Fleece quality: Printing velvets are usually first brushed and printed, whether they are single or double suede. They must be washed and slashed before printing. 3. Wide, slack and shrinkage problems of flannel: In the flannel processing, each machine must maintain a small tension to prevent the fabric from shrinking too much and ensure that the cloth width before tentering is on the prescribed cloth width. . The fleece fabric is relatively soft and most likely to produce weft. Special attention should be paid to the pre-print weft, not to exceed the standard, and to install the weft assembly on the key machine. The warp shrinkage of the fleece is not a problem. Most of them can reach below 3%. The zonal shrinkage rate is high, with the vast majority at 6%-10% or even more than 10%. Must be dealt with from the pre-treatment and finishing. 4. Printing: All kinds of printing processes and post-processing are the same with cotton printing. According to the characteristics of velvet production, the following items must be noted: Necklace carving is appropriate to do deeper. Because the surface of the fabric has poor hairiness and poor permeability, the barrel depth is deeper than normal flat cloth, 0.01-0.02 (1-2 silk). With the addition of a scraper on the stencil, all cilia adhered to the snophob can be removed. The microphone requires smoothness and does not make the reticular surface line too sharp. After the flannel printing, the number of flat washings is less, so that one flat wash can achieve the desired effect. In order to make the hand feel soft, the enzyme desizing step can be added after the first washing. If you choose paint printing, just steam, do not flat wash. Can get a good plush, velvet clear, smooth contour effect, flannel printing after the flat wash also need to pay attention to the down hair straight hair problems, post-processing will prevent scratches.
