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

[0105] Using the triangular tube grinding yarn-grinding feather shuttlecock tension gripping and drawing measuring device and method of the present invention, the pilling and feather shuttlecock drawing of the full wool 2×8.2tex double-strand yarn with a yarn number of 16.4tex Force is measured, and its measurement condition parameter and actual measurement result are shown in the column of embodiment 1 in the table below and the extraction force measurement curve is shown in Figure 6 . 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. Telephoto microscope lens 41 and CCD camera 42 observe tangentially, the original yarn sample basically has no plush effect, while the polished yarn ...

Embodiment 2

[0107]Using the tension gripping and drawing measuring device and method of square tube grinding feather shuttlecock of the present invention, the pilling and pulling force of feather shuttlecock with yarn number of 13.1tex are measured, and the results are as follows: The measurement condition parameters and actual measurement results are shown in the column of Example 2 in the table below and the extraction force measurement curve is shown in Figure 6 . 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. 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 ha...

Embodiment 3

[0109] Adopting the tension gripping and drawing measuring device and method of the pentagonal barrel grinding feather badminton of the present invention, when the tension double rod 31 does not pressurize the yarn layer, the fluffing of the polyester-cotton blended yarn whose yarn number is 18.3tex Spherical and feather shuttlecock pulling force is measured, and its measurement condition parameters and actual measurement results are shown in the column of embodiment 3 in the table below and the pulling force measurement curve is shown in Figure 6 . 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 relat...

Abstract

The invention relates to a polygonal cylinder type yarn grinding hairness and hair bulb tension holding pull measuring device and method. The device comprises a polygonal cylinder with 3-6 angles, a friction mechanism, a yarn layer tension mechanism, a microscopy camera mechanism, a pull mechanism, a yarn frame, a static raising device and a control and data collection analyzing system. The method includes: when dense yarn winding is completed, performing Lissajous curve friction on yarn on the polygonal cylinder angle by angle to obtain yarn grinding samples, pressurizing the yarn grinding samples turning to the top angle by angle, holding yarn layers, clamping ground hairness or hair bulbs for pull force measurement and hairness or hair bulb formation observation until pull measurement of each angle is completed so as to obtain hairness and hair bulb microscopy formation values and pull force curves under tension holding. The device and the method are fast, simple, practical, accurate, applicable to hairness and hair bulb sampling of yarn. measurement of hairness and hair bulb pull curves and formation, and comprehensive evaluation of anti-hairness and anti-hair-bulb performance of 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...
