Embodiment Construction

[0016] The inventors of the present invention recommend the following examples. Please refer to the accompanying drawings, this embodiment is carried out according to the clear technical solution in the summary of the invention. Yarn under test 1 by speed V 1 Constant device 2 and speed V 2 Constant device 3, both of them maintain the speed of one end of yarn 1 as V 1 , the other end is V 2 In this way, the yarn is kept moving under a certain tension, and the speed signals of the two are sent to the speed difference tension constant controller 4, and the tension is calculated, and the speed difference tension constant controller 4 feeds back the signal to the second speed constant The yarn speed is maintained, and the yarn speed data and tension data are sent to the computer 11, and the computer 11 also instructs the constant speed differential tension controller 4 when necessary. In the yarn segment between the two speed constant devices, three detection devices are arran...

Abstract

The present invention provides one kind of yarn quality and component detecting method and device. Yarn holding certain moving speed and tension is set in the view field of sensor, and under lighting or electric field, yarn quality data sensed by CCD, chroma sensor and capacitance sensor are transmitted to computer for processing so that the yarn attributes, such as yarn size, color nonuniformity, component ratio, impurity, etc. are output and displayed. Furthermore, the fabric effect of the yarn may be also imitated and displayed in computer. Through the spectral analysis on the data collected via the CCD, chroma sensor and capacitance sensor, periodical rule and peak value may be found out for directing the producting of yarn and fabric.

Description

Technical field: [0001] The present invention relates to the field of measurement of length, thickness and similar linear dimensions and the measurement of angle, area, irregular surface or contour, and relates to measuring the diameter of an object when it is moving by an optical method, and to measuring the chromaticity of an object by an optical method, It also relates to measuring the composition of an object by a capacitance method, and is a method and a device for detecting yarn quality and composition ratio. Background technique: [0002] In order to control the overall surface quality of the yarn, its test is carried out by winding the yarn onto a rectangular or trapezoidal black plate to make a side-by-side comparison of some relatively short different lengths of half of the yarn sample. This test has been carried out. Standardized as ASTM 2255-64, the method describes winding yarn onto a rectangular or trapezoidal plate and then testing the wound plate by taking in...
