The invention relates to an online detection method by circularly rubbing hairiness on the yarn surface, and belongs to the technical field of textile testing. According to the method, a sixth yarn guide roll and four friction rollers are arranged on the supporting rod of a support; friction grooves are formed in the friction rollers, and are filled with friction sheets; a sixth yarn running groove is formed in the sixth yarn guide roll; a closed-ring running path is formed by the sixth yarn running groove, friction grooves in the four friction rollers, a tension yarn guider, a brush runner, afirst yarn guide roll, a second yarn guide roll, a third yarn guide roll, a fourth yarn guide roll, a fifth yarn guide roll, a fixed yarn guide groove and a roller jaw; and a closed-ring yarn is assembled on the closed-ring running path, winds a friction roller set in an S-shaped path and is subjected to repeated circular rubbing of the friction sheets in the friction grooves, while hairiness issubjected to real-time continuous accurate detection, and yarn continuous circular friction and real-time online detection are combined to realize real-time continuous accurate detection of yarn friction.
Description
technical field [0001] The invention relates to an on-line detection method for circular friction yarn surface hairiness, 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 cause excessive h...
