Description
Technical field
The invention belongs to textile test field, it is related to a kind of washing shrinkage of textiles test method and its test device, tool
Body be related to it is a kind of may be implemented washing shrinkage of textiles test in mark, measure, calculate and provide automatically test report method and
Device.
Background technique
Washing shrinkage is after indicating that fabric washing is dry, and the changed index of fabric size, it, which is that fabric is important, takes
One of performance.The size of washing shrinkage is very big to the influence of specification of ready-made clothes or other braiding articles.During tailoring dress material, especially
It is when tailoring the clothes of two layers of two or more fabric joint closes, it is necessary to the size of washing shrinkage is considered, to guarantee the specification of ready-made clothes and wear
Requirement.
Washing shrinkage of textiles test must be carried out according to related check standard.The either washing shrinkage of textiles examination of which state
Standard inspection is quasi-, the big small sample of at least 500mm × 500mm will be first taken among fabric to be measured with washing shrinkage marking plate, in each examination
Three pairs of mark points are at least respectively done on the length and width direction of sample, the distance between each pair of mark point at least 350mm is being advised respectively
The front and back for determining processing routine measures the distance between each pair of mark point.
As for mark point or use marking ink or fabric marker printer；It is made marks using stitching into fabric
Line, color and fabric color should form sharp contrast；Using staple (suitable for the examination that do not stir in test
Sample).
It by fabric sample and accompanies and washes fabric and be put into togerther washing shrinkage washing machine, and pour into national standard detergent.After washing, with baking
Dry machine drying or naturally dry.Fabric is shakeout, the size after washing and drying is measured with steel ruler, washing shrinkage=(size-after washing
Size before washing)/wash preceding size × 100%.Under normal circumstances, fabric radial direction, the washing shrinkage of broadwise will measure.Traditional
Washing shrinkage test have the disadvantage that 1, fabric be it is soft, artificial force is big a little or a little bit smaller, and same people measures the ruler come
Very little is that discrepant, different people does same test, as a result and is had probabilistic；As a result poor repeatability, arbitrariness is also big；2,
Manual operation, speed is slow, with low content of technology, repeats uninteresting, inefficiency；3, the stamp-pad ink of marking is needed with fabric color not
It replaces together, it has not been convenient to, low efficiency.
Summary of the invention
Reproducible the purpose of the present invention is to provide a kind of variation of automatic measurement mark point distance, accuracy rate is high, adopts
With reflective ink paste, make floor light with ultraviolet light, whatsoever the fabric of color, washing shrinkage of textiles test side all applicatory
Method and its test device.
To achieve the goals above, the technical solution of the present invention is as follows: providing a kind of washing shrinkage of textiles test method, including
Following steps:
(1) fabric to be measured is laid on platform to fixed, extended flat；
(2) it is arranged that the print head of reflective ink paste is passed through in fabric surface to be measured, broadwise respectively stamps the crosses of three groups of 350mm spacing
Label；
(3) after label is printed, fabric to be measured is taken out；
(4) fabric to be measured and accompanying wash fabric be put into togerther it is dry after washing shrinkage washing of drum type washing machine；
(5) fabric to be measured after drying is laid on platform to fixed, extended flat again；
(6) camera is transmitted to computer processor after acquiring the cross mark on fabric to be measured, and computer processor is certainly
The distance between cross mark is corresponded to after dynamic identification fabric sample washing, washing shrinkage is calculated, exports result；
(7) fabric to be measured is taken out, into testing next time.
Another object of the present invention is to provide a kind of washing shrinkage of textiles test devices, by Mark-print System and calculating
Machine processor is made up of connection；The Mark-print System includes the data acquisition group connecting with computer processor
Part, textile fixing process component and print components；The data acquisition components by fixed link and be arranged below fixed link and
The vision camera composition connecting with computer processor, vision camera includes vision light source, camera and imaging sensor；It is described
Textile fixing process component is made of spring clip and roller, and one end of platform is arranged in spring clip, and roller is arranged on platform
And it can be moved along guide rail；The print components are by reciprocating lever, elevating lever and printhead cluster at elevating lever one end and print head connect
It connects, the other end is connect with reciprocating lever, and reciprocating lever can be parallel to plateau levels movement, and reflective ink paste is arranged on print head.
Washing shrinkage of textiles test method and its test device of the present invention have it is below the utility model has the advantages that
1, the present invention uses mechanical automation franking point, and printing is precisely, high-efficient；
2, ink uses reflective stamp-pad ink, makees floor light with ultraviolet light, whatsoever the fabric of color, all applicable, nothing
It needs to change；
3, the variation of automatic measurement mark point distance, it is reproducible, accurately；
4, automatic calculated result, automatically generates report, and high-effective and labour-saving is time saving；
5, fabric is smoothed out using mechanical hand roll, reduces manual intervention, firmly uniformly, repeatability is strong；As a result stable；
6, artificial ruler is replaced to measure the distance of each group echo with image recognition, high degree of automation is rapidly and efficiently reduced
Human error, it is time saving and energy saving.
