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.
More than 90% of the market Liaoning customized Cotton ribbon It is made of cotton polyester thread or polyester cotton thread, but pure cotton thread is rare in the market, and the price is surprisingly high! Polyester cotton yarn just neutralizes the advantages of pure cotton and polyester, depending on the composition of polyester in cotton. Generally, the yarn of cotton ribbon is made by adding a small amount of polyester into cotton, so that it can have the advantages of pure cotton and polyester cotton. It is easy to wash, heat resistant, alkali resistant, moisturizing, sanitary, wear-resistant, not shrink, not easy to wrinkle, not easy to deform, not easy to stick wool, and so on! Liaoning Cotton ribbon manufactor The key is that the proportion of cotton and polyester is appropriate! The identification method of pure cotton webbing and polyester cotton webbing is simply to take the cut thread and burn it. If there is any hard block, it is polyester cotton yarn containing polyester, and if it is completely reduced to ashes, it is authentic pure cotton.
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.
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, draw all the "high" parts of the text or pattern in a cycle according to the weave rule that has been analyzed and determined and the actual fabric, and then draw the "high" parts of the background color (color other than text or pattern) in a cycle according to the weave rule. After all the "high" parts are drawn, The "low" part of the pattern and bottom is drawn according to the analyzed organization rule until the drawing is completed.
