Embodiment 1

[0084] Adopt measuring device and method of the present invention, be that the yarn number is 16.4tex full hair 2 * 8.2tex double strands of fluffing and pilling is done from the first step to the third step of the full set of measurements, which Measurement condition parameter and actual measurement result are shown in the following table embodiment 1 column and the process measurement curve of described second step sees Figure 4 . From the measured results, it can be seen that the number of hairballs per unit area, the diameter of hairballs and their coefficient of variation obtained from the tangential observation and the normal phase observation of the worn-out full wool strands are in good agreement, indicating that the two forms of observation are effective and precise. Observation of the normal overall appearance, the original yarn sample basically has no plush effect, while the ground yarn sample has obvious plush effect, respectively, the average height of the initi...

Embodiment 2

[0086] Adopt measuring device and method of the present invention, to yarn number number be 13.1tex wool acrylic blended yarn's pilling property is done from the process measurement and calculation of the first step and the second step described, its measurement condition parameter And actual measurement result sees the process measurement curve of following table embodiment 2 column and described second step Figure 5 . From the measured results, it can be seen that the number of hairballs per unit area, the diameter of hairballs and their coefficient of variation obtained from the tangential observation and the normal phase observation of the worn wool and acrylic blended yarn have a good consistency, indicating that the two forms of observation are effective. ,precise. Observation of the normal overall appearance, the plush effect of the original yarn sample is not obvious, but the plush effect of the polished yarn sample is obvious, respectively, the average height of the...

Embodiment 3

[0088] Adopt measuring device and method of the present invention, to yarn number number be that the fluffing and pilling of the polyester-cotton blended yarn of 18.3tex is done from the comparative measurement and calculation of described first step and the 3rd step, adopt CCD camera 61 Observation of the upper position and the projection light source 64 second quadrant 180 °, then the CCD camera 61 moves to the lower position and the projection light source 64 turns to the observation of the first quadrant 30 °, the measurement condition parameters and actual measurement results of the experiment are shown in the following table embodiment 3- column. It can be seen from the actual measurement results that the number of hair balls per unit area obtained from the tangential observation and normal observation of the worn polyester-cotton blended yarn is very small because the cotton fiber does not pill, and the diameter of the hair balls is too large due to the polyester pilling...

Abstract

The invention relates to a device and method used for measuring the pilling form and pulling force of densely arranged yarns. The device consists of a yarn winding mechanism, a yarn grinding mechanism, a yarn feeding mechanism, a translational driving mechanism, a wearer collector, a microscopic camera system, a clamping and pulling mechanism, and a control and data analysis system. The method comprises the steps of bridging and rotating the yarn feeding mechanism and the yarn grinding mechanism through the translational driving mechanism, kinetically matching with the yarn winding mechanism to achieve the winding of the densely arranged yarns and yarn grinding sample preparation, and carrying out on-line measurement on yarn samples in the process of yarn grinding as well as comprehensive measurement, calculation and evaluation on yarn grinding samples in a final state. The device is ingenious in structure, practical, and precise and quantitative in measurement, and the device and the method are an in-situ measuring device and an in-situ measuring method which are multi-purpose and multi-index in one measurement. The device and the method can be used for the measurement of the pilling quantity, form and wear quantity of the yarns and pulling forces of hairiness and hair bulbs as well as the comprehensive evaluation of the pilling resistance.

Description

technical field [0001] The invention relates to a device for measuring the pilling amount, shape and non-removability of yarn, and an evaluation method for predicting the pilling resistance of textiles by using the device, which belongs to the technical field of textile quality evaluation and testing. Background technique [0002] The shape of the hairiness on the yarn and the difficulty of being pulled out not only have a great influence on the pilling of the yarn and whether it is easy to fall off after pilling, but also have a great influence on the anti-pilling of the fabric made of it. Sex is also closely related. Therefore, fast and targeted evaluation should observe the yarn, especially the observation of pilling on evenly arranged yarn sheets, which is more representative, targeted and simple. [0003] There are many forms of existing yarn hairiness measurement, but all of them are single measurement of yarn apparent hairiness, and there is no measurement related to...
