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

Embodiment 1

[0093] Adopting the pilling amount and shape measuring device and method of the quadrangular tube pressurized grinding process of the present invention, the pilling property of the double-strand yarn of full wool 2×8.2tex whose yarn number is 16.4tex is measured, Its measurement condition parameter and actual measurement result are shown in the column of embodiment 1 of the following table and the measurement curve of the grinding process is shown in Figure 4 . From the measured results, it can be seen that the number of pills per unit area, the diameter of pills and their coefficient of variation obtained from the tangential observation of the worn full wool strands and the predicted yarn pilling level have a good consistency, indicating that the Effective and accurate devices and measurement methods. The telephoto microscope lens 41 and the CCD camera 42 observe tangentially, the original yarn sample basically has no plush effect, while the polished yarn sample has obvious...

Embodiment 2

[0095] Adopt the pilling amount and shape measuring device and method of the octagonal cylinder pressure grinding yarn process of the present invention, the yarn number is measured for the pilling of the wool acrylic blended yarn of 13.1tex, its measurement condition parameter and The actual measurement results are shown in the column of Example 2 in the table below. From the measured results, it can be seen that the number of pills per unit area, the diameter of pills and their coefficient of variation obtained from the tangential observation of the worn wool and acrylic blended yarn are in good agreement with the predicted yarn pilling level, indicating that The device and the measuring method are effective and accurate. Telephoto microscope lens 41 and CCD camera 42 observe tangentially, the original yarn sample basically has no plush effect, but the plush effect of the polished yarn sample is obvious, which are respectively compared with the average initial hairiness heigh...

Embodiment 3

[0097] Using the pilling amount and shape measuring device and method of the twelve-corner cylinder pressurized yarn grinding process of the present invention, the pilling and featherball pulling force of the polyester-cotton blended yarn whose yarn number is 18.3tex Measure, its measurement condition parameter and actual measurement result are shown in the column of embodiment 3 of the following table. From the actual measurement results, it can be seen that the number of hair balls per unit area obtained from the tangential observation of the worn polyester-cotton blended yarn is very small due to cotton fiber pilling, the diameter of hair balls is too large due to polyester pilling, and the coefficient of variation is small. and because of the difference in sampling volume, the CVD observed in the tangential direction is relatively large, indicating that the device and measurement method are effective and accurate. The comprehensive estimated value of the pilling resistance...

Abstract

The invention relates to a device and a method for measuring fuzzing amount, balling amount and morphology during pressurized yarn grinding of polygonal barrels. The device comprises four multiples of polygonal barrels, a friction mechanism, a tension mechanism, a projection and pickup mechanism, a creel, an electrostatic raising device and a control and data acquisition analysis system. The method comprises the steps of accomplishing close packing and yarn winding to form a yarn winding sample, rotating clockwise directly through the polygonal barrels angle by angle, observing raising of the yarn winding sample angle by angle, and the morphology after delay of 1-3 angles, then delaying by 1-3 angles for synchronous pressurization and stabilization, sampling fuzzing and balling to form a yarn grinding sample, and after rotating the yarn grinding sample by 180 degrees angle by angle (namely, rotating the polygonal barrels by a cycle), performing synchronous raising and morphology observation angle by angle till friction sampling and morphology measurement of each angle are finished. The measuring device and the method are quick, practical, in-situ, dynamic and precise, and use the same sample, can be used for sampling of the fuzzing and the balling, measurement of the fuzzing amount, the balling amount and the morphology of a yarn, and comprehensive evaluation of fuzzing and balling resistance 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...
