The shape and extraction measuring device and method of the tension controllable fluffing and pilling of the polygonal cylinder

Abstract

The invention relates to a polygonal-barrel tension-controllable fuzzing and pilling form and pulling measurement device and method. The device comprises a polygonal barrel, a friction mechanism, a tension mechanism, a microscopy photographing mechanism, a pulling mechanism, a creel, a static raising device and a control and data collection analysis system. The method includes the steps that after yarns are arranged and wound, by means of the polygonal barrel rotating angle by angle clockwise, raising, form observation and fuzzing and pilling sample preparation are carried out synchronously angle by angle on original yarn, ground yarn is obtained, raising and form observation are carried out synchronously angle by angle on the ground yarn until friction sample preparation and form measurement of all angles are finished, and then a microscopy form value and a pull force curve of yarn hairness and hair balls pulled from the ultimate ground yarn which pre-tension is exerted on are measured angle by angle. The measurement device and method are quick, easy and convenient to use, practical and accurate, can be used for fuzzing and pilling sample preparation of the yarn, measurement of fuzzing and pilling yarn hairness, hair ball quantity and form and the pulling curve and comprehensive evaluation of anti-pilling performance of the yarn.

Description

technical field [0001] The invention relates to a measuring device and method for measuring the shape and pulling behavior of hairiness and hairballs by winding yarn on a polygonal tube and controlling the fluffing and pilling and the tension during pulling out in the technical field of textile quality evaluation. Background technique [0002] The shape of the hairiness on the yarn and the difficulty of being pulled out have a great influence on whether the yarn pills and whether it is easy to fall off after pilling, so it is necessary to observe the hairiness on the yarn. After rubbing and pilling, the number of pills and whether they are easy to fall off have a great influence on the pilling of the final fabric. Existing yarn hairiness testers have various forms, and the testing principles and structures are also different. It can be roughly divided into: [0003] The first category: diffuse reflection method. Using light irradiation, test the intensity and change of li...

AI Technical Summary

Problems solved by technology

The shortcoming of this method is: 1) test data repeatability is poor

2) Because the long hairs are easier to fall and bend during the test, the number of long hairs in the test is relatively small

3) The stage difference of the test instrument is large

[0007] The above observation methods for yarn-like substances cannot observe the entire process of pilling, and cannot obtain the appearance and morphology characteristics of hairiness and pilling produced at different stages of the yarn, as well as the index reflecting the tendency of yarn pilling, that is, the relationship between hairiness. The magnitude of the entanglement force
