Sizing percentage online regulation and control method based on yarn form change

Abstract

The invention relates to a sizing percentage online regulation and control method based on yarn form change. The sizing percentage online regulation and control method comprises the following specificsteps: 1) acquiring a dried sheet yarn video image; 2) measuring the diameter of each yarn in each frame of video image, and calculating a mean value d; 3), taking the average diameter of the yarn within 10-15 minutes after driving as the standard diameter D of the batch of yarn; 4) calculating the difference value Delta d between the current yarn diameter mean value d and the standard diameter D, Delta d = d-D; 5) taking Delta d as one of the input layer feature vectors, and calculating the size of a grouting force change value Delta F by adopting a deep learning neural network; and 6) adjusting the grouting force in real time according to the grout force change value Delta F obtained in the step 5). The diameter variation Delta d is obtained by measuring the instant diameter d of the dried yarn and comparing the instant diameter d with the standard diameter D, and the squeezing force is further adjusted on line according to the size of the Delta d, so that the diameter of the driedyarn tends to be stable, and the stability of the sizing quality in the sizing production process is guaranteed.

Description

Technical field: [0001] The invention relates to an online regulation method of sizing rate based on the change of yarn shape. Background technique: [0002] Sizing is a key link in the textile production process, which directly affects the strength, elongation, wear resistance and hairiness of warp yarns, which is related to weaving efficiency and fabric quality. Sizing warp yarns is beneficial to improve the breaking strength of warp yarns and reduce the rate of weaving end breaks; it is beneficial to sizing yarns to maintain elongation, so that warp yarns can withstand the elongation caused by the opening effect during weaving; it is helpful to improve the wear resistance of yarns, Maintain the strength of the yarn and avoid hairiness regeneration; make the hairiness close to the body, and at the same time increase the rigidity of the hairiness, so as not to cause entanglement and accumulation to cause unclear opening and block the warp. [0003] The sizing rate is one o...

Problems solved by technology

The soft test method is based on the variables in the sizing process, establishes a mathematical model between each variable and the sizing rate, and infers the result of the sizing rate; however, this method is limited by the detection conditions and the error of the detection equipment, which affects the calculation results

In summary, although the above methods can detect and regulate the sizing rate online, they all have defects such as low detection accuracy or lag in regulation, which are difficult to meet the needs of actual production
