Embodiment Construction
[0012] A method for on-line detection of cyclic friction fabric surface hairiness according to the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0013] see Attachment.
[0014]An on-line detection method for surface hairiness of circulating friction fabrics, comprising a first fabric guide roller 1, a lower hair removal roller 5, an upper hair removal roller 2, a second cloth guide roller 3, a detection head, a laser transmitter, and a driving roller 11. The yarn hairiness meter and support frame 12 composed of passive rollers, the area between the projection receiver of the yarn hairiness meter detection head and the circular emitting surface 6 of the laser emitter constitutes the hairiness detection area, the passive roller and the active roller 11 The roller nips are meshed with each other, the roller nips are located in front of the hairiness detection area, the roller nip lines are located on the vertical plan...

The invention relates to an on-line detection method of circulating type friction fabric surface hairness, and belongs to the technical field of weaving test. According to the on-line detection methodof circulating type friction fabric surface hairness, fabric surface hairness is detected using a hairness device, a third fabric guide roll and a friction roller assembly are arranged on a support rod of a support frame, the friction rollers are provided with friction grooves; friction plates are arranged in the friction grooves; the third fabric guide roll is provided with a third cloth delivery groove; a closed operation circular path is formed by the third fabric delivery groove, the four friction grooves of the friction rollers, a second fabric delivery groove, a first fabric delivery groove, and a roller nip; in test, the closed operation circular path is sleeved with a closed circular cloth strip with a width equals to or smaller than that of the first fabric delivery groove, the friction roller assembly is sleeved by the closed circular cloth strip in an S-shaped manner, the upper surface and the lower surface of the closed circular cloth strip are designed to be staggered, sothat the closed circular cloth strip is loaded with a plurality of times of circulating friction by the friction plates, real-time continuous detection on surface hairness is realized at the same time. According to the on-line detection method, fabric continuous circulating friction and real-time on-line detection are combined, so that a problem in the prior art that on-line real-time continuousdetection of cloth sample friction is impossible to realize is solved.
Description
technical field [0001] The invention relates to an on-line detection method for hairiness on the surface of a circulating friction fabric, 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 ...
