Problems solved by technology

[0004] The above-mentioned experimental instruments and methods are only used to measure a single index. It is a traditional single-machine single-measurement single-index or multi-machine multi-measurement multi-index measurement. It is impossible to complete the measurement of yarn and fabric on the same instrument, or complete yarn or fabric. All measurements of surface hairiness, compressibility and friction properties of

Embodiment 1

[0045] Embodiment 1, hairiness index-displacement curve obtains

[0046] According to the measurement requirements and perform the above measurement preparation steps, fix the bobbin on the positioning rod 13, then pull the yarn along the guide roller 68 to the nip of the back roller 48, drive the back roller 48 to rotate and pull the yarn through the stepping motor 41 To the front roller 39 jaws, the stepper motor 31 drives the front roller 39 to rotate and draw the yarn to the sample bucket 35. Start the high-resolution digital CCD camera 84 to capture the surface morphology of the sample on the guide roller 68 within a set period of time, and obtain the hairiness index-displacement curve as shown in figure 2 .

Embodiment 2

[0047] Embodiment 2, apparent thickness parameter obtains

[0048] According to the measurement requirements, the fabric sample cut to a certain length and width is loosely placed on the positioning rod 13, and then the fabric is pulled along the guide roller 68 to the nip of the back roller 48, and the back roller 48 is driven by the stepping motor 41 to rotate and pull the fabric to At the front roller 39 jaws, the stepper motor 31 drives the front roller 39 to rotate and draw the fabric to the sample bucket 35. The driving circuit drives the stepper motor 61 to rotate the screw rod 64 to drive the grip rod 65 and the compression block 67 to move down vertically to compress the surface of the sample on the guide roller 68, and the pressure is induced by the force sensor 73 connected to the compression block 67, Thus, the pressure-displacement curve and the sample thickness-pressure curve are obtained. According to the sample thickness (H1, H2) measured under the action of tw...

Embodiment 3

[0051] Embodiment 3, pressure-displacement curve and parameter acquisition

[0052] According to measurement requirements, cut the fabric sample of certain length * width, after the test procedure of embodiment 2 is finished, drive the stepper motor 51 to rotate the screw rod 54 to drive the holding rod 55 and the briquetting block 57 to compress the sample in cycle (cycle) The number of times can be set, and the present embodiment only does one cycle), thus obtaining the pressure-displacement curve see image 3 , according to the pressure-displacement curve, the corresponding mechanical characteristic parameters can be obtained.

Abstract

The invention relates to an optics mechanic composted measuring method and device of colored thread or clothe surface feather, apparent denseness, compression ability and frictional ability. The method comprises: picking up and roller drawing the sample by cord roller, taking sample's surface feather sharp dynamically by high-resolution figure CCD camera and obtaining feather quantity, compressing the picking up sample by driven compressing block, measuring sample's apparent denseness, doing up-and-down movement to compress the sample on the supporting block by driven compressing rod to measure sample's compression ability and compression resilience. The device comprises: cartage, stalling, operating rod, cord roller, compression block, a pair of fore-roller, briquette, back-up block, a pair of rear-roller, sample ladle, high-resolution figure CCD camera, sensor connected separately with compression block, briquette and back-up block, roller draw-off mechanism, alter steering mechanism, system for collecting, controlling and processing the force and shape signal and computers.

Description

Technical field: [0001] The invention belongs to the technical field of textile precision measuring instruments, and relates to an optical and mechanical combined measurement method and device for the surface characteristics of yarns, ropes and fabrics, and is applicable to the evaluation of weavable and processable performance of yarns, and the bulkiness, gloss and texture of fabrics. Research and measurement of performance evaluation, etc. technical background: [0002] The quantity and distribution of hairiness on the surface of the yarn, the compression performance and the friction performance of the yarn not only affect the processing performance of the fabric during forming, such as warp and weft stoppage, unclear weaving opening, weaving efficiency, production rate, product weaving defects and subsequent processes The quality of dyeing and dyeing, but also affect the quality of the fabric, appearance, wearing comfort and other performance. Therefore, it is of great p...
