Problems solved by technology

However, by superimposing the collected signals hundreds of times, although the weak signal of fiber oil content can be detected, the detection time of fiber oiling rate is greatly increased (about 4 minutes), which cannot meet the requirements of fiber manufacturers to control the detection time within Request within 1min

Abstract

The invention discloses a method for detecting the oil applying rate of fiber. The method comprises the following steps of: 1, acquiring a low-field nuclear magnetic resonance signal of standard fiber and performing linear fitting to obtain a calibration curve; 2, acquiring a low-field nuclear magnetic resonance signal of tested fiber and performing wavelet soft-threshold filtering processing to obtain a filtered reconstruction signal; and 3, substituting the filtered reconstruction signal into the calibration curve to obtain the oil applying rate of the fiber. According to the method, the detection accuracy of the oil applying rate of the fiber is increased, and the detection time is reduced to be less than 1 minute from the original 4 minutes.

Description

technical field [0001] The invention relates to a method for detecting fiber oiling rate, in particular to a method for detecting fiber oiling rate based on wavelet filtering technology and applied to low-field nuclear magnetic resonance. Background technique [0002] Fiber oiling rate detection speed and result accuracy are very important in the fiber production process. The application of low-field nuclear magnetic resonance detection technology in the detection of fiber oiling rate shortens the detection time from several hours to several minutes, and at the same time, the accuracy and stability of the detection results can also be greatly improved. At present, the foreign and domestic markets in this field are mainly monopolized by German Bruker Company and British Oxford Company. Due to the involvement of commercial secrets and the difficulty of obtaining the underlying data of NMR, it is difficult to find relevant literature on fiber low-field NMR signal processing at...
