Indirect plate making method: the indirect film is first exposed, hardened with 1.2% H2O2, developed with warm water, and dried to make a strippable graphic negative. During plate making, the adhesive film surface of the graphic negative is closely attached to the stretched screen, the adhesive film is tightly attached to the wet screen by extrusion, the film base is removed, and the screen is dried by wind. Process flow: 1. Stretched wire mesh - degreasing - drying. 2 Indirect film - exposure - hardening - development - fitting - drying - revision - blocking. 3 Straight mixed plate making method: first, paste the photosensitive adhesive layer on the screen frame with water, alcohol or photosensitive adhesive, dry it with hot air, remove the substrate of the photosensitive film, and then print the plate. After developing, the screen plate is made.
Dalian Customized 3-strand twisted rope The convex and concave convex fabrics are compact and delicate on the front, with strip or pattern convex patterns, and rough on the back, with long floating lines. Wool fabric: single side woolen fabric, with the pile side being the front side of the fabric. For double-sided fleece fabric, the front side shall be the smooth and tidy side. Customized 3-strand twisted rope wholesale Observe the selvage of the fabric: if the selvage is smooth, the neat side is the front side of the fabric. For double-layer, multi-layer and multiple fabrics, if the warp and weft density of the front and the back is different, the front side has a larger density or the front side has better raw materials.
Computer drawing process. Many friends are particularly interested in computers. Xiao Bian has briefly introduced the textile technology of computer jacquard belts before, but many people are still interested in how to draw computer jacquard belts. Today, we will introduce its drawing method according to the drawing process of the ribbon. Single color change: change the color of the left or right mouse button in the picture according to the position within the parameter range, and change the color of a connected color block within the parameter range. The color changed depends on whether the left or right mouse button is pressed. Select a rectangular range: click two points in the editing area to form a rectangular range with these two points as the opposite corners, so that you can clear, cut, copy, and organize this rectangular range. Clear out of parameter drawings: Clear the drawings outside the set range of longitude and latitude.
Width detection: the tolerance of webbing with width of 1 "and above shall not exceed ± 0.25 points; The tolerance of webbing with width of 25MM and above shall not exceed ± 0.5MM; The standard tolerance of webbing width of 1 "and less than 25MM shall not exceed ± 0.25MM; Note: The flat end and herringbone edging webbing must be of sufficient size, but not more than 0.25 points. Thickness inspection: the tolerance shall not exceed ± 0.1MM; Color difference test: there is no yin and yang color on the belt surface by naked eye, and the needle edge and cloth edge cannot be exchanged for the color and texture (the needle edge of each woven belt must be of one color). Singeing and labeling: Each bag ribbon must be singed thoroughly, but cannot be burnt. The quality inspector shall inspect the packaging label to be consistent with the actual goods (specification, color, quantity), and seal it for warehousing. If errors and omissions are found, the relevant processes shall be traced in time, and the relevant personnel shall be held accountable according to the seriousness of the case.
In the 1970s, due to the promotion of continuous ribbon dyeing and ironing machine, the processing of ribbon has developed from the traditional process of dyeing before weaving to weaving before dyeing, weaving before bleaching, ironing after processing, and the ribbon technology has entered the ranks of mechanized mass production. In the early 1980s, the industry introduced high-speed shuttleless loom, ironing machine, wrapping machine, warping machine, etc. from Switzerland, Italy and the Federal Republic of Germany, and the ribbon technology entered a new stage of development. The progress of webbing technology has brought about the upgrading of products. In 1980, the rubber ingot belt was developed, which has the characteristics of soft, light, thin, firm, small elongation, small impact force, short and flat joints.
