Method of testing hairiness on double surfaces of fabric cloth sample with yarn hairiness instrument

Abstract

The invention relates to a method of testing hairiness on double surfaces of a fabric cloth sample with a yarn hairiness instrument and belongs to the technical field of texture test. A roller nip is arranged in the front of a hairiness detection zone of the yarn hairiness instrument. A first cloth passing trough is arranged behind the hairiness detection zone. A second cloth passing trough is arranged at the right side of the first cloth passing trough. The centers of the first cloth passing trough, the second cloth passing trough, the roller nip and the hairiness detection zone are arranged in the same plane. A lower and an upper hairiness unbending rollers are arranged between the first cloth passing trough and the second cloth passing trough. The fabric cloth sample is unreeled from a coil and successively passes through the second cloth passing trough, the upper hairiness unbending roller, the lower hairiness unbending roller and the first cloth passing trough and enters the hairiness detection zone, wherein the hairiness on the double surfaces of the fabric cloth sample are unbent and exposed by the upper and the lower hairiness unbending rollers. The hairiness, under vertical irradiation of laser, is continuously and accurately protected on a detection head of the yarn hairiness instrument. The method solves the technical problem that the yarn hairiness instrument cannot detect the hairiness on the double surfaces of the cloth sample. The method is low in cost, is simple in operation and is easy to promote.

Description

technical field [0001] The invention relates to a method for testing hairiness on both sides of a fabric sample with a yarn hairiness meter, 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 wil...
