Description

Compact spinning effect testing device for yarns Technical Field The utility model relates to the technical field of yarn testing, in particular to a device for testing the compact spinning effect of yarns. Background At present, yarn appearance, particularly yarn hairiness and pilling phenomena are very important to textile clothing factories, and in order to improve the yarn hairiness and pilling phenomena, many yarn manufacturers adopt a compact spinning process to produce yarns. The gathering effect of the compact spun yarn directly affects the hairiness and pilling level of the yarn. At present, yarn hairiness is detected in textile factories, but the compact spinning aggregation effect of the yarn cannot be detected. When weaving is carried out later, if the yarn with poor aggregation effect is tightly spun, the fiber is easy to slip to form defects such as wool grains, details and the like, the yarn is easy to break, the weaving efficiency is reduced, and meanwhile, the anti-pilling grade of the yarn is also reduced. At present, the aggregation effect of the compact spinning yarns by a textile mill is manually measured, and the aggregation effect of the yarns is observed after the yarns are rubbed by the finger belly, but the strength of the yarns rubbed by each person and the roughness of the finger belly are different, so that the testing effect is different, and the aggregation effect of the yarns is difficult to objectively and uniformly judge.
