Problems solved by technology

Chinese patent: ZL99217564.9, 2000 ] , but there are also problems. The test equipment in the report did not effectively extract the mechanical performance indicators, but only the comprehensive value of the mechanical properties. In addition, the utility model patent is only suitable for measuring yarn
[0005] The biggest defect in the above-mentioned test instruments and methods is that the measurement of fabric and yarn cannot be completed on the same instrument.

Embodiment 1

[0051] Example 1, the composite force-displacement characteristic curve is obtained.

[0052] The driving screw 12 of the moving plate 1 and the driving stepper motor 15, the two-stage contact block thickness measuring mechanism 3 and the driving micro-motor 37, and the tension sensor 51 of the single fixed-point supporting needle 5 are all fixed with the frame. The moving plate 1 is driven by the screw to move in the vertical position; the two-stage contact block thickness measuring mechanism 3 drives the worm gear 35 and the worm 36 to rotate the rotating screw 34 by driving the micro motor 37, and pushes the holding plate 31, the contact block bracket 32 ​​and the sliding spring to slide Block 33 moves down to finish the thickness measurement of yarn or fabric sample; converted into a digital signal.

[0053] Rotate the screw rod 25 symmetrically according to the requirements of the measurement, and move the left and right upper fixed clamps 2 symmetrically to the desired ...

Embodiment 2

[0057] Embodiment 2, measurement result.

[0058] The composite force-displacement characteristic curve was obtained by measuring the average value of 10 fabric samples by this action, and the characteristic index of the mechanical properties of the fabric was extracted from it. The results are shown in Table 1.

Abstract

The invention relates to a combined measuring device for the mechanics index of the cloth and yarm and it use. It includes a step motor and a computer with a stretching force sensor, a signal gathering and program driving control module and a data collection chart, a pair of clamper which can adjust the position and tension set on the movable board1, a double needle pressing machine4; a single fixed pointed keeping needle suspended on the pull sensor5; two touch touching pachometer. The characteristics of the invention lies in that the overall measurment of the weight, bend, stretching, friction, stretch relaxation, compress thickness and shear property of the cloth and yarm can be completed in mobil way at one time, besides, the invention provides a simple mechanism and compact and light and handy structure, adapting to be fitted onto the stretch test instruments of various types of micromechanics measuring sensors.

Description

Technical field: [0001] The invention belongs to the technical field of textile precision measuring instruments, and relates to a measuring device and application including the mechanical properties of fabric and yarn in textile. The device can be applied to yarn spinnability evaluation, fabric style evaluation measurement and process parameter optimization and quality control in textile production. Background technique: [0002] The style of fabric and yarn plays a vital role in the shaping and wearing of textiles. It not only affects the smoothness, softness and drape style of underwear, but also determines the style characteristics of crispness, bending resistance and shape retention of outerwear. Therefore, in order to meet the various needs of textiles, it is necessary to select the corresponding fabric and yarn style (including mechanical properties such as weight, bending properties, friction properties, tensile properties, relaxation properties, compression thickness...
