Due to the problems of coarse details and unevenness on the yarn, some weaker fragments on the yarn may be formed to form a yarn breakage, which is called "weak strong ring of yarn". The existence of the weak ring of the yarn is one of the key factors that restrict the speed of the spinning machine. The strong weak ring on the yarn is mainly due to the presence of details and fragmentation on the yarn. The strong characteristics of the original yarn include average strength, strength unevenness, average elongation and elongation unevenness . Generally, the average strength of the warp yarn is 15cN/tex, the intensity unevenness is about 9%~10%, the average weft yarn strength is 12cN/tex, and the strong unevenness is about 9%~10% . The average elongation at break is generally controlled within 2%. Strong weak ring The strong weak ring generally refers to the minimum strength of the yarn. The important strength indicator of the air jet loom stop is the strong weak ring. It is generally considered that when the fineness of the yarn is only 40% of the normal yarn, the weak ring of detail will inevitably cause the broken head. Causing stoppage, if the strong weak ring is at 4cN/tex, the elongation is less than 2%, which will inevitably cause breakage. Other powerful weak rings account for 61% of the details, such as weak cockroaches, poor joints, and mixed thick sections, which will cause latitude and longitude stagnation, accounting for about 39% . In addition to the average strength and strong unevenness of the warp and weft yarns, the strong weak ring is an important factor. Japanese businessmen buy yarns in China, with special emphasis on the number of strong weak rings of 100,000 latitude. According to the 100,000-weft breakage detected by the high-speed large-capacity powerful machine tensogiet to judge the possibility of yarn purchase, the strong requirements for the yarn in the knitting and weaving factories of a considerable scale should emphasize the level of strong weak ring, some related enterprises in China. The tensogiet strength meter should be equipped as much as possible to keep the quality of the original yarn off. Causes and solutions for strong weak rings There are three main types of details on the original yarn: a short velvet detail, a coarse detail knot, and another long detail or multiple short details that can cause a broken head. In order to reduce the strong weak ring and provide a good raw yarn for the downstream process, corresponding measures must be taken , such as the new roving frame in the four-roller drafting form of the four-unit transmission, which eliminates the details caused by the switch car and improves on the other hand. The drafting strip is dry, the coarse detail is reduced, and the gearing of the drafting part is strengthened, so that the loosening gap is not ensured, and the drafting process is ensured, which is also an important method for reducing the detail. In addition, reasonable configuration of the process, the selection of good drafting parts, such as rubber rollers, aprons, upper and lower pins, pressurizing mechanism, etc. are also one of the factors to reduce the details.
