Abstract
The invention relates to knittability characterization equipment and method for an extremely fine yarn. The equipment comprises a yarn package, two fixed pulleys, two flat plates, a knitting needle, acontroller, a sensor, a receiver, an image collector, a gravity weight and a yarn clip. Rotation shafts of the fixed pulleys are mutually parallel and are parallel to a horizontal plane. The two flatplates are mutually parallel. The rotation shafts of the fixed pulleys and the flat plates are mutually parallel. The two flat plates are spaced between the two fixed pulleys. The highest points of the two fixed pulleys and the two flat plates are located on the same horizontal plane. According to the method, through adoption of the equipment, whether the extremely fine yarn is unwound successfully or not, bending rigidity, initial break strength, initial break extension, a friction residual intensity ratio and friction fuzzing degree are tested, and knittability is determined. The knittability characterization equipment for the extremely fine yarn provided by the invention is simple in structure and is convenient for operation. According to the knittability characterization method for the extremely fine yarn, a knitting technology and a specific process of the extremely fine yarn are taken into full consideration, and the knittability of the extremely fine yarn can be rapidly and accurately determined.
Description
Technical field [0001] The invention belongs to the technical field of textile testing instruments, and relates to a device and method for characterizing the knitability of extremely fine yarns. Background technique [0002] Knitting due to its technological characteristics, in the knitting process, there are both friction between the yarns, and friction between the yarns and the knitting needles, yarn guides and other metals. At the same time, the yarns need to be stretched and bent into loops. Knitting yarn has higher requirements for its performance. Different types and specifications of yarns often have different morphological characteristics and mechanical properties, and not all yarns can be woven into knitted fabrics smoothly. Therefore, to examine and evaluate whether the yarns used can meet the requirements of knitting and weaving before formal production is of great significance for production efficiency, cost and fabric quality, especially for expensive high-performan...
