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

[0093] 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 actual measurement results, it can be known that the final state of the full-hair strand yarn on the bobbin is more fluffy, with an average length of 5.3mm and a density of 0.141; while the average length of the hairiness of the original yarn sample of the full-hair strand is 1.2mm and a density of 0.0011 is basically normal and there is no fluff phenomenon. Compared with the two, the fluff of the whole wool strand is significant. The actual measurement of the extraction of hairiness and hairball has higher extraction force and less extr...

Embodiment 2

[0095] 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 known that the fluffing of the wool-acrylonitrile blended yarn in the final state on the bobbin is more obvious, the average length of hairiness is 8.2mm and the density of hairiness is 0.213; while the average length of hairiness of the original yarn sample is 1.4mm and the density of hairiness is 1.4mm. 0.0010 is basically normal and there is no fuzzing phenomenon. Compared with the two, the fuzzing of the wool-acrylic blended yarn is very significant, indicating that the repeated translational friction of the vertical ya...

Embodiment 3

[0097] Using the measuring device and method of the present invention, the pilling and pilling properties of the polyester-cotton blended yarn whose yarn number is 18.3tex are compared, measured and calculated from the first step and the third step, using 45° symmetry The projection illumination of the double projection light source 62 on the optical axis of the CCD camera 61, that is, the observation of the second quadrant 135° and the third quadrant 225° and the use of asymmetric Lissajous curve friction, the actual measurement results are shown in the column of Example 3 in the table below . From the actual measurement results, it can be known that the fluff of the polyester-cotton blended yarn in the final state of the yarn bobbin is more obvious, with an average length of hairiness of 8.7mm and a density of 0.108; while the average length of hairiness of the original yarn sample is 0.7mm and a density of 0.0007. Normal, no fluff phenomenon, compared with the two, the fluf...

Abstract

The invention relates to a device and method for measuring friction fuzzing and pilling forms and a pulling-out force of bobbin yarns. The device comprises a cop creel for clamping cops to rotate, a friction mechanism for fuzzing and pilling bobbin yarns, a collecting mechanism for collecting shaving and shearing filoplumes and fuzzy balls, a static raising device for helping filoplumes to stand, a pulling-out mechanism used for measuring the pulling-out force of the filoplumes and fuzzy balls, an imaging system for observing the filoplumes and fuzzy balls of the bobbin yarns, a computer and a data acquiring and controlling system. The method comprises the steps of: measuring the prominence of the filoplumes and the number, the form size and distribution of the fuzzy balls after coaxially jacking and clamping the cops, carrying out friction for fuzzing and pilling and synchronously measuring the prominence of the filoplumes, the number of the fuzzy balls, the abrasion loss and retention of the filoplumes and fuzzy balls, and the pulling-out force of the filoplumes and fuzzy balls of the process and a final friction sample. The device and method are exquisite, practical, accurate and quantitative, and can be used for measuring the fuzzing and pilling forms of the bobbin yarns and comprehensively evaluating the fuzzing and pilling resistance. In situ measurement of multiple functions in one machine and multiple indexes in one-time measurement is adopted in the device and method.

Description

technical field [0001] The invention relates to a device for measuring the pilling amount, shape and non-removability of bobbins by friction, 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 the yarn pilling evenly arranged on the bobbin, which is representative and simple, and more predictable and targeted in advance. [0003] There are many forms of existing yarn hairiness measurement, but all of them are single measurement of yarn appa...
