Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that there is no objective, effective, quantified and repeatable method to evaluate the appearance of the folds of clothing fabrics during dressing in the prior art, and to provide a method for characterization of the folds of the cloth surface. The implementation of the method is completed by three functional modules that are connected but independent of each other, namely, the simulation wrinkle module, the image projection scanning module and the data analysis module.

Abstract

The invention relates to a wearing cloth cover fold appearance characterizing method. The wearing cloth cover fold appearance characterizing method comprises the steps of: firstly, adopting a simulation crinkling module to simulate cloth cover wearing crinkling; secondly, adopting an image projection scanning module to acquire fold images without changing the states of folds; and thirdly, adoptinga data analysis module to process the fold images and then evaluate the fold appearance of the cloth cover in wearing. The simulation crinkling module comprises a sample fixed supporting tray, a sample movable supporting tray, a forearm, an upper arm, a joint, a pressing and fixing member, a rotation control member and a fixing member, wherein the joint is a movable connector connecting the forearm and the upper arm, the sample fixed supporting tray sleeves the outer side end of the forearm, the sample movable supporting tray sleeves the outer side end of the upper arm, the pressing and fixing member is used for fixing both ends of a fabric on the circumferential surfaces of the sample fixed supporting tray and the sample movable supporting tray, the rotation control member is used for controlling the sample fixed supporting tray to rotate around the forearm, and the fixing member is used for fixing the sample movable supporting tray on the upper arm. The wearing cloth cover fold appearance characterizing method provided by the invention is objective and effective, quantitative in characterization and has good repeatability.

Description

technical field [0001] The invention belongs to the technical field of textile and garment testing, and relates to a method for characterization of the folded appearance of clothing. Background technique [0002] The folded appearance of clothing fabrics refers to the folded state or behavior of the clothing worn on the human body when the human body is still or in motion, and is one of the important characteristics that reflect the beauty of clothing. There is a difference between the folded appearance and the draped appearance of clothing fabrics. The drape focuses on the deformation state of the fabric in a fully free, semi-free state and its own gravity; while the folded appearance reflects that the clothing fabric has been cut, stitched, ironed and other processes And after dressing, it will show bending, arching, wrinkling and other effects under the constraints of all parties. Therefore, the folded appearance of clothing fabrics can better reflect the visual beauty o...
