Description
Technical field
The invention belongs to textile garment the field of test technology, are related to a kind of dressing cloth cover fold appearance characterizing method.
Background technique
Garment material body fold appearance refer to the clothes being worn on human body human body is static or motion state following table
The fold state revealed or behavior are that reflection clothes wear one of important feature of aesthetic feeling.The fold appearance of garment material and outstanding
Vertical appearance be it is distinguishing, pendency stresses to show fabric in the full shape freely, under semi-free state and self gravitation effect presented
Change state；And fold appearance reflection garment material have passed through after the techniques such as cutting, suture, ironing and dressing and be under each side's constraint
The bending revealed, arch camber, corrugation and other effects.Therefore the fold appearance of garment material proper can more reflect clothes in reality body
Visual sense of beauty afterwards.
Since fabric cuts out shape, the complexity of sewing process and dressing condition and fabric performance diversity, to clothes
The evaluation method of fabric dressing fold appearance still tried at present with ready-made clothes-is made-subjective assessment based on；Current apparatus measures
Method can only reflect indirectly the dressing fold appearance of garment material by the recovery angle and cloth surface evenness of fabric.
Recovery angle testing experiment only reflects the wrinkle resilience performance [GB/T3819- of textile material in one direction
1997] [ISO2313-1972] [AATCC Test Method 66-2014] [Chinese patent: 201310180184.X], and take
The practical fold for taking generation in the process of dress fabric irregular and interactional feature with multiple, multidirectional, form, therefore more
For complexity, replys Angle Measurements and be difficult to definitely reflect practical situation.Flatness method [GB/T 13769-2009] [ISO 7768-
2009；ISO 7769-2009；ISO 9867-2010][AATCC Test Method 124-2011；AATCC Test
Method 128-2017] in ranking process to environmental requirement harshness, the result of grading is influenced by rating reviewer's subjective factor, and
It is divided with five to six hierarchy levels to evaluate fabric to be measured, step span is big, it is difficult to accurate reflection cloth cover fold state.
In addition, replying the Mechanics of Machinery wrinkle resistance that the whole degree method of horn cupping peace is only used for characterization fabric itself, measurement is obtained
Result be difficult to reflect garment material body fold appearance, it is more difficult to for predicting dressing visual appearance effect.
During the measurement that image processing techniques and 3-D scanning technology are gradually applied to above two method is implemented, to assist reality
Purpose that is now quick, objective, accurately measuring.But image processing techniques measurement error when handling pattern sample is obvious, and three-dimensional is swept
Retouch that technical costs is higher and operating process is cumbersome.
Chinese patent 200910095226.3,201210261100.0,201320318212.5 and 201510706987.3
Etc. referring to the compression of simulation human body, twist the device for the movements such as stirring, be bent and enable cockline, pass through the figure of acquisition Wrinkle fabric sample
Picture or 3 d scan data are to characterize its wrinkle resistance or flatness；But the above method requires to try in corrugated fabric
Sample is measured after modes drawout again by removing or hanging etc. manually naturally, sprawls the tested cloth cover of the process change of fabric
Fold state, and influenced by manual operation obvious, reduce the repeatability of measurement process.
To sum up, the fold mode of appearance generated in dressing for garment material, currently still trying on after ready-made clothes is made
Experiment and subjective assessment are main evaluation method, and this method is at high cost, time-consuming and laborious, can not be quantified, and experience, accuracy are relied on
