An intelligent soft measurement method for sizing rate of sizing

Abstract

An intelligent soft measurement method for sizing sizing ratio belongs to the technical field of automatic measurement. According to the analysis of the sizing mechanism and the composition of the sizing machine, the auxiliary variables for the soft measurement of the sizing rate of the sizing machine are determined to be: the speed of the sizing machine, the pressure of the low-pressure sizing roller of the sizing machine, the pressure of the high-pressure sizing roller of the sizing machine, and the pressure in the sizing tank of the sizing machine. Size concentration and size temperature in the sizing tank of the sizing machine; collect the historical operation data of the sizing machine to establish a sample data set; establish a soft sensor model for the sizing rate of the sizing, and obtain the relationship between the auxiliary variable and the sizing; the sizing rate of the sizing Calculate online. The method of the invention can accurately calculate the sizing rate of sizing on-line, has fast calculation speed and high precision, can realize on-line detection, and reduces energy and material consumption in the sizing production process; it has a wide range of applications, and can be used for other quality after proper modification of the data source. Indicators such as moisture regain, elongation, etc. can be measured online; it can easily share information with other links in cotton textile production, and provide reference for the operation of other links.

Description

technical field [0001] The invention belongs to the technical field of automatic measurement, relates to the technical field of textile sizing production detection, in particular to an intelligent soft measurement method for sizing rate of sizing. Background technique [0002] The sizing process is a key process in textile production. The quality of sizing is directly related to warp yarn strength, hairiness and wear resistance, which in turn affects the efficiency of looms. The production process of sizing is complicated, and consumes a lot of raw materials and energy, so it is vividly called "Tiger's Mouth" in the industry. The indicators used to measure the sizing effect of warp yarn in the sizing process mainly include sizing rate, moisture regain rate, elongation rate, penetration rate, covering rate, size film integrity rate, etc., among which the sizing rate is a key quality indicator in the sizing production process. [0003] The existing online detection methods of...

Problems solved by technology

The detection of sizing rate by near-infrared spectroscopy has the advantages of fast detection and non-destructive detection, but its disadvantage is that it is greatly affected by the environment, especially the water vapor in the sizing production site has a great influence on the detection results

Although the above three detection methods can realize the detection of sizing rate, due to their own shortcomings, it is difficult to meet the requirements of fierce competition in product quality and production efficiency in today's textile industry
