Measuring device and method for fluffing and balling shape as well as hair bulb stripping of yarn

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...
