Abstract
The utility model relates to a fabric glossiness tester, which belongs to a new tester. The utility model not only has a right reflection light tester but also has a diffuse reflection light tester. The testers are composed of a double convex lens and a photosensitive resistor. A compensating bridge comparator circuit is adopted simultaneously to enhance sensitivity and resolution of the fabric glossiness tester. The utility model is suitable for testing surface lustre of bright materials, such as metals, glass, plastics, etc., and is suitable for testing surface lustre of fabric having a rough surface and a plurality of weave structures and colors. The lustre figure measured of the fabric surface basically coincides with the lustre figure of the fabric which is graded by the traditional eyesight.
Description
The utility model is a kind of novel testing tool.
Before the present utility model, the gloss of fabric all is to evaluate with sight.Because the influence of the environment (temperature, light power etc.) when evaluation person's age, sex, psychological condition, experience level, evaluation causes evaluation result to differ greatly.Your thatch (GeltI) glossmeter of the '30s West Germany lid was still with sight and observed comparison this century.To the seventies, though the UGV-4D type glossmeter that Japanese ス ガ makes has changed the way of observing with sight, still exist not enough: 1. this instrument has only the normal reflection detecting device, does not have the diffuse reflection detecting device, and the temperature reflection exactly can reflect the characteristics of fabric sheen.2. the resolution of instrument is low.For the low gloss face, just can not differentiate its size when particularly gloss difference is less.3. fabric color is not resolved to the influence of test gloss.4. the evaluation of instrument test result and sight is inconsistent.
Fabric sheen tester described in the utility model mainly is made up of light source (W), sample bench (T), detecting device (P), analog to digital conversion circuit (D), numeral demonstration (E), stabilized voltage supply (V) etc.Shown in figure one.
The light path system of fabric sheen instrument described in the utility model is as shown in Figure 2: W be 15 watts of instrument of YQ6 volt with bulbs as light source; T is a sample bench, P
1Be the normal reflection photodetector; P
2Be the diffuse detecting device vertical with normal reflection light; L
1, L
2, L
3, L
4All be that diameter is 20mm, focal length is the biconvex lens of 41.52mm; S
1Be the smallcolumn diaphragm of diameter 1mm, S
2It is the rectangular light hurdle of 6 * 9mm.
The principle of work of fabric sheen instrument described in the utility model is:
The light that light source W sends is through biconvex lens L
1With smallcolumn diaphragm S
1The back forms approximate pointolite, passes through biconvex lens L again
2Form approximate parallel beam.Rectangular light hurdle S
2Controlled the facula area that shines on the sample.The acceptance angle that shines the incident angle of the light on the sample and receiver can be any angle of 0～75 °.As sight can be any angle when observing fabric sheen.Adopting the light source incident angle in the utility model is 60 °, and the acceptance angle of normal reflection photodetector is 60 ° also, and the acceptance angle of the detecting device that diffuses is negative 30 °, is in order to make apparatus structure simple and easy to operate.Normal reflection photodetector P
1With the detecting device P that diffuses
2All be made up of biconvex lens and the photoresistance with fine spectral characteristic and photoelectric characteristic, this just makes detecting device replace people's eyes well, and can reflect the catoptrical situation of change of fabric exactly.For the electric signal that records is compared, adopted bridge circuit comparator circuit (L) in the circuit with compensation, make circuit have simple in structure, stable, highly sensitive characteristics.Signal relatively shows that by numeral (E) provides the fabric sheen value through analog to digital conversion (D) back.Also can and print with the supporting automatic processing test result of microcomputer.Stabilized voltage supply (V) adopts the thin film circuit voltage regulation unit of high stable, has improved the stability of instrument.Consistent for the fabric sheen value that makes this instrument test with the fabric sheen of sight evaluation, must adopt following empirical Calculation formula to carry out data processing, promptly
In the formula: G
C---the fabric face gloss number
G
S---fabric face normal reflection light value
G
D---fabric face is vertical diffuse reflection light value with normal reflection light.
Fabric sheen instrument described in the utility model has characteristics simple in structure, easy to operate, highly sensitive and that resolution is high.Outside the material surface gloss such as decapacitation test metal, glass, plastics, it is coarse particularly to be suitable for test surfaces, has the fabric face gloss of various textured structure and color.The fabric face gloss numerical value that records and traditional sight evaluation fabric face gloss numerical value basically identical.
Claims (3)
1, a kind of proving installation of fabric face gloss is made up of light source (W), sample bench (T), detecting device (P), analog to digital conversion (D), numeral demonstration (E), stabilized voltage supply (V).It is characterized in that detecting device (P) is by normal reflection photodetector (P
1) and the diffuse detecting device (P vertical with it
2) and compensation comparator circuit (L) composition, numeral shows that (E) measures normal reflection light value (G
S) and diffuse reflection light value (G
