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.
After the weft tube is formed by the yarn warp cylinder and weft winding, it is inserted on the fixed gear seat of the knitting machine, and the weft tube rotates along the 8-shaped track to draw the yarns to cross weave with each other. Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic process of weaving is: bleaching and dyeing - weft rolling - weaving - off machine shearing - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality.
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.
In this business, there is no doubt that the quotation is very important. I think many colleagues who make webbing are very familiar with their own products and can quote their own prices when they get their own products. If you come across a ribbon that is not made by yourself, can you quote an accurate price? I think it is impossible. Here is a brief introduction to how to quote an accurate price for a ribbon. First of all, the customer needs to understand this ribbon and be able to answer any question clearly.
Jilin customized Brocade ribbon 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, and draw the "high" part of all characters or patterns in a cycle according to the weave rule determined by analysis and combined with the actual fabric, Jilin customized Brocade ribbon manufactor Then draw the "high" part of the bottom color (color other than text or pattern) in a cycle according to the organization rule. After all the "high" parts are drawn, draw the "low" part of the pattern and bottom according to the analyzed organization rule until the drawing is completed.
According to the functional data learned by Xiao Bian, the temperature of the lit cigarette is about 700 ℃, and the continuous burning time of a cigarette is about 15 minutes, which is a long time. However, the spontaneous ignition point of common combustibles is very low, such as paper, cotton, linen and knitted fabrics, whose ignition point is mostly 200 ℃ to 300 ℃, so it is easy to cause fire. Turning to the statistics of major and catastrophic fires nationwide, there are many records of fires and casualty accidents caused by smoking after drinking, smoking in bed, littering cigarette butts and other reasons. The typical case is the Great Khingan Mountains forest fire in 1987, which caused a heavy loss of 6.913 billion yuan. It was later discovered that four of the first five fire spots of the fire were caused by human beings, and two of the fire spots were ignited by the cigarette butts of three "smokers".
