Abstract

The invention relates to a device and method for measuring curvature, friction, evenness and hairiness of yarn in a combined mode. The device is composed of a yarn guiding mechanism, a hairiness measuring mechanism, an evenness measuring mechanism, a force measuring mechanism, a dragging and winding mechanism and a bottom plate assembly and is further composed of a corresponding form and force signal collecting, driving control and processing system and a computer. The method for achieving the device comprises the steps that yarn is guided through the yarn guiding mechanism, and the yarn is dragged through the dragging and winding mechanism; the hairiness measuring mechanism is used for horizontally supporting the yarn and extracting the surface hairiness of the yarn, and the hairiness index is obtained through the processing system; a capacitance plate of the evenness measuring mechanism is used for obtaining the evenness of the yarn; a bending mechanism, composed of a pressing needle and double carrier rollers, of the force measuring mechanism is used for bending the yarn, and then the yarn anti-bent strength is obtained; a friction roller of the force measuring mechanism rubs with the yarn, the tension of the yarn before being input into the friction roller and the tension of the yarn after being input into the friction roller are obtained, and then the yarn friction coefficient is obtained. The device and method have the advantage of combining optics, electrics and mechanics measurement.

Description

technical field [0001] The invention relates to a measuring device and method for measuring bending and friction of yarns, evenness and hairiness, and belongs to the technical field of textile precision measuring instruments. Background technique [0002] The quantity and distribution of hairiness on the yarn surface, bending performance, friction performance and evenness not only determine the quality of the yarn, but also affect the forming process of yarn products (such as clothing fabrics), such as the distribution of yarn after sizing. Skeins, shedding during weaving, warp yarn breakage, dyeing uniformity, and the appearance, feel and performance of the final product. Therefore, it is of great practical significance to measure and quantify the hairiness, bending performance, friction performance and evenness of the yarn surface. [0003] At present, the instruments for measuring the above-mentioned properties of yarns at home and abroad mainly use single-machine single...
