Problems solved by technology

The shortcoming of this method is: 1) test data repeatability is poor
[0008] The above-mentioned observation methods for yarn-like substances cannot observe the entire process of fluffing and 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 fluffing and pilling, that is, the hairiness ratio. The magnitude of the entanglement force

Embodiment 1

[0098] Using the measuring device and method of the present invention, a complete set of measurements from the first step to the third step is performed on the pilling property of the wool / viscose 2×6.1tex double-strand yarn with a yarn number of 12.2tex , its measurement condition parameter and actual measurement result are shown in the column of embodiment 1 of the following table and the process measurement curve of the second step is shown in Figure 5 . From the measured results, it can be seen that the number of hairballs per unit area (Nt and Nn), 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 Formal observations are effective and accurate. Observation of the normal overall appearance, the wound yarn sample basically has no plush effect, while the ground yarn sample has obvious plush effect, which is re...

Embodiment 2

[0100] Adopt measuring device and method of the present invention, the fluffing and pilling of the blended yarn of wool and PTT fiber that yarn number is 15.8tex 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 are shown in the following table embodiment 2 column and the process measurement curve of described second step sees Figure 6 . From the measured results, it can be seen that the number of hair balls per unit area, the diameter of hair balls and their coefficient of variation obtained from the tangential observation and the normal phase observation of the blended yarn of wool and PTT fiber after abrasion have a good consistency, indicating that the two forms The observations are effective and accurate. Observation of the normal overall appearance, the plush effect of the wound yarn sample is not obvious, but the plush effect of the polished yarn sampl...

Embodiment 3

[0102] Using the measuring device and method of the present invention, the pilling and pilling properties of cotton and linen blended yarns with a yarn number of 17.8tex are compared, measured and calculated from the first step and the third step, using a CCD camera 61 Observation of upper position and projection light source 64 second quadrant 165 °, then CCD camera 71 moves to lower position and projection light source 74 turns to observation of first quadrant 25 °, the measurement condition parameters and actual measurement results of the experiment are shown in the following table embodiment 3 Column. From the actual measurement results, it can be known that the number of hair balls per unit area obtained from the tangential observation and the normal phase observation of the worn cotton and linen blended yarn is very small because the cotton fiber is not pilling, and the diameter of the hair balls is too large because of the pilling of the polyester. And the coefficient o...

Abstract

The invention relates to a device and a method for measuring fluffing and balling shape as well as hair bulb stripping of a yarn. The device comprises a mechanism clamping hair bulbs to implement stripping, a yarn delivery mechanism performing equal-tension close packing, a yarn winding mechanism winding the yarn at a constant speed, a yarn grinding mechanism performing friction on the close packed and wound yarn, a translation driving mechanism driving the yarn delivery mechanism and the yarn winding mechanism in a switching manner, an abrasion object collector, a microimaging system and a control and data analysis system. The measuring method comprises the steps that a gap bridge wheel of the translation driving mechanism transposes the yarn delivery mechanism and the yarn grinding mechanism, and is matched with the yarn winding mechanism, so that close packing yarn winding and yarn grinding sampling are achieved; a yarn grinding sample in a yarn grinding process is measured in situ; and comprehensive measuring and evaluation are performed on the yarn grinding sample in a final state. The device is ingenious in structure, practical, precise in measuring, quantitative, and multipurpose, is an in-situ measuring device for measuring multiple indexes, and can be used for measuring of the hair feather and hair bulb quantity, the shape, the abrasion loss and the back-and-forth drag stripping property of the yarn, and for comprehensive evaluation of the fluffing resistance and the balling resistance.

Description

technical field [0001] The invention relates to a device for measuring the pilling amount, shape and non-removability of yarns, and an evaluation method for predicting the pilling resistance of textiles made 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 rela...
