Abstract
The utility model relates to a fabric surface deformeter which is a new deformeter. Light reflection principle is utilized in the utility model. A deformation coefficient which can show a plurality of fabric surface performances, such as fuzzing and pilling, deformation in water, wrinkle durability, etc. can be get by testing intensity of light reflection before and after fabric deformation. The testing result can not be affected by fabric color, fabric lustre, fabric weave structure, etc. The whole operating process automation can be achieved by applying a microcomputer, and the testing is rapid and accurate, which can make the test result is closely coincide with the traditional eyesight grading.
Description
The utility model is a kind of novel testing tool.
Before the present utility model, estimating the deformability of fabric face, as pilling, fall into water distortion, rivel permanance etc., all is the method for grading with sight, the method that promptly adopts the sample estimated to compare with Pyatyi standard sample photo.This sight assessment method belongs to hand and touches soon method, and classification is coarse, does not have strict gradational boundary, and the influence of objective condition etc. when being subjected to evaluation person's age, experience level, psychological condition, evaluation, causes evaluation result to differ greatly.To the seventies in this century, the day bottom letter good fortune of Aichi, Janpan education university waits introduces reflection method and the tracer method that adopts goniophotometer, with regard to surface property test the having carried out research and inquirement of cloth.But he points out in this research report: reflection method is not suitable for colored fabric, and tracer method is not suitable for soft fabric.He advises that associating reflection method and tracer method finish the test of fabric face performance for this reason, and this will make the testing tool complex structure, troublesome poeration, and do not seen this quasi-instrument so far and come out.
Fabric face deformability tester described in the utility model is a kind of new instrument of utilizing the principle of light reflection to be developed into, because fabric face state difference, to reflection of light effect difference, by test to intensity of light reflection before and after the fabric distortion, calculate deformation coefficient, deformation performance to fabric face, as pilling, fall into water and be out of shape, rivel permanance etc. provides quantitative data, owing to be the result who calculates with the test data before and after a kind of sample deformation, so be not subjected to the color of fabric, gloss, influences such as textured structure, from then on, the examination to the fabric face deformability strides forward Instrument measuring from the sight evaluation.
The principle of work of fabric face deformability tester described in the utility model is as figure.The light that pointolite (1) sends becomes directional light through lens (2), this bundle directional light shines on the tested sample (3) to be fixed into firing angle, focus on through lens (6) from the normal reflection light of sample (3) reflection, the photelectric receiver (7) that light after the focusing is placed on the focus receives, arrive analog to digital converter (9) through amplifier (8) again, import microcomputer (10) subsequently.Wherein light source (1) is 8 volts 20 watts a incandescent lamp bulb; Lens (2) and (6) are the common double convex lens, and the incident angle that shines sample (3) glazing is a fixed angles, can be the arbitrary fixed angles (not comprising 0 degree and 90 degree) between 0 to 90 degree, are preferably the arbitrary fixed angles between 50 to 80 degree; Sample bench (4) is the plane that can put sample, other has stepper motor (5) to link to each other with it, sample bench (together with sample) can planar be rotated, this just can be from the intensity of light reflection on all directions test fabric surface of sample, make test result more can reflect the overall picture of fabric face, improved precision of test result; The illuminating area of tested sample is not a bit, but face, illuminating area is different and different with test purpose, surveying pilling is the circular area of diameter 30 to 80mm, be preferably the circular area of diameter 40 to 70mm, surveying falls into water is deformed into the circular area of diameter 100 to 250mm, and preferably the circular area of diameter 150 to 200mm is surveyed the rectangular area that the rivel permanance is preferably 75 * 15mm; Photelectric receiver (7) is by common photosensitive resistor group one-tenth and be connected with multiplying arrangement (8); Analog to digital conversion (9) is general integrated converter; Computing machine (10) can be all kinds of microcomputers, except that finishing data processing and test result show to print, also make the robotizations such as calibration, control, measurement, computing of instrument, improved accuracy and sensitivity, certainly data presentation also can be without computing machine, and shows with general data.
Fabric face deformability tester described in the utility model is calculated the deformability that deformation coefficient is represented fabric face by the test to intensity of light reflection before and after the fabric distortion, and deformation coefficient is bigger, and the expression distortion is more serious, and the general formula of deformation coefficient is
B=(G
1-G
2)/(G
1) * 100%.B is a deformation coefficient in the formula; G
1Be the fabric intensity of light reflection before being out of shape; G
2Be the fabric intensity of light reflection after the distortion.
Deformation coefficient (B) can be any data of 0～100%, can be converted into deformation coefficient the Pyatyi standard of traditional sight grading by computing machine.This instrument can be simultaneously to deformation coefficient and demonstration of Pyatyi standard or printing.
Fabric face deformability tester described in the utility model has the design feature of a tractor serves several purposes, can measure the pilling of fabric, fall into water distortion, rivel permanance etc.Because the using miniature computing machine has been realized the robotization of whole operating process, make test rapidly, accurately, test result and traditional sight grading numerical value basically identical.
