Changchun Customized 3-strand twisted rope Steps of printing 3-strand twisted rope about 3-strand twisted rope wholesale Many friends don't know how to print, but there are actually two methods. So the master of PP Ribbon Factory will let you know. Direct plate making method: the method of direct plate making is to first place the photosensitive film of the wrist plate base coated with photosensitive material face up on the working table, place the stretched wrist net frame flat on the film base, then put photosensitive paste in the screen frame and apply pressure coating with a soft scraper, remove the plastic film base after drying and filling, and attach the photosensitive film wrist screen for printing. After developing After drying, screen printing is made. Process flow: stretched screen - degreasing - drying - peeling substrate - exposure - development - drying - revision - blocking
If the weft needle is damaged, replace it or beat it with gauze; If the steel buckle is damaged, hit it with gauze or replace the steel buckle; The coir filament piece is damaged or the shutdown piece is damaged. Replace it with a new one. Causes of poor needle edge: uneven weft yarn thickness; The knitting needle is not properly laid, too long or too short; The pan head moves abnormally, sometimes tight, sometimes loose; The weft wheel is not round enough and deformed; The fixing pin of knitting needle is worn; Precautions: change another weft yarn; The knitting needle is longer or shorter according to the thickness of the ribbon. Generally speaking, the length of the knitting needle is just enough to remove the weft; Fix both sides of the pan head firmly, and do not let the pan head lean against the iron frame on both sides; Replace the weft wheel with a new one; Replace the fixed rod or go to processing.
It is precisely because of this performance that silk fabrics are more suitable for direct contact with human skin. Therefore, we can directly wrap a unique garment with silk scarves in the hot summer, which is not only beautiful but also comfortable. Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation is proud of its porous fiber structure. There are many tiny fibers in a silk fiber, and these tiny fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a large amount of air in these gaps, which prevents the heat emission and makes the silk have good warmth retention.
The unused ones from the knitting production line are called. The strength, width, thickness, elongation and stiffness described above are all measured on the knitting production line. The data measured on the knitting production line are called data. The safety belt installed in the car should be worn by the passengers after they get on the car. The use process is an aging process, and its strength will decline. In order to ensure that the safety belt can effectively protect the passengers before the vehicle is scrapped, the strength of the webbing shall be measured after simulating the working conditions. This strength is called the strength after the environmental test. After the environmental test, the strength includes light treatment, low temperature treatment, high temperature treatment, immersion test and wear treatment.
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.
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.
