A method for testing fabric hairiness on one side on a yarn hairiness meter

Abstract

The invention relates to a method for testing fabric single-side hairiness on a yarn hairiness instrument, and belongs to the technical field of textile testing. According to the method, a light shielding plate is arranged above a lower half circle of the round emitting surface of a laser emitter of the yarn hairiness instrument; a cloth conveying roller is arranged between a detection head and the light shielding plate; a cloth feeding opening of a cloth conveying groove formed in the cloth conveying roller corresponds to a cloth roll; a cloth discharging opening of the cloth conveying groove corresponds to a roller tong opening; belt type fabrics unreeled from the cloth roll enters a position between the light shielding plate and the detection head through the cloth feeding opening of the cloth conveying groove of the cloth roller; the belt type fabrics are continuously and flatly folded back in the upper edge part of the groove bottom of the cloth conveying groove, so that the hairiness of the outer surface of the belt type fabrics are prominently shown at the folding-back position; the prominently shown hairiness is continuously and vertically projected on the detection head of the hairiness test instrument under the illumination of laser given out by the upper half circle of the round emitting surface of the laser emitter; the technical problem that the hairiness on the surface of the fabrics cannot be tested on the existing yarn hairiness instrument is solved. The method has the advantages that the cost is low; the operation is simple; the popularization is easy.

Description

technical field [0001] The invention relates to a method for testing the hairiness of one side of a fabric on a yarn hairiness tester, which belongs to the technical field of textile testing. Background technique [0002] Hairiness is one of the important indicators to measure the quality of yarn and fabric. Yarn hairiness refers to the fiber end or fiber ring exposed on the surface of staple fiber yarn. When the yarn is stressed, the hairiness cannot lack the point of holding the force, so the yarn hairiness does not help the yarn strength; and if the yarn hairiness is too much, the friction of the yarn increases, and the yarn is more likely to be worn and broken in the subsequent processing, affecting the yarn strength. Processing efficiency: During the weaving process, yarns with excessive hairiness are easy to entangle, resulting in unclear openings and affecting weaving efficiency and quality. Excessive yarn hairiness and excessive wear in the weaving process will caus...
