Problems solved by technology

Generally speaking, fabrics with a DP greater than 3.5 are smoother, and the flatness of grades 1 and 2 is poor
[0003] There are three main problems in the existing method: 1. It is mainly aimed at the detection of the flatness of the fabric after washing, and it is not suitable for the unevenness caused by wrinkling during the actual wearing process of the garment; 2. The subjective evaluation is vulnerable to human factors. Third, the evaluation results are only 5 grades, which is not accurate enough, resulting in great differences in the flatness of fabrics within the same grade

Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, a method for testing and evaluating the flatness of clothing wearing, the specific steps are as follows:

[0031] Step 1. Select a number of fabrics to be tested with different flatness. After ironing and flattening, the fabrics to be tested are cut and sewed according to the uniform model, cutting and sewing conditions, and made into try-on clothes (consisting of tops and trousers). And iron it to make the surface flat and free of creases. In order to minimize the error and influence caused by manual operation, the above operation steps are all completed by the same person;

[0032] Step 2. Select a try-on with a suitable figure and size, and ask the try-on not to be too loose after wearing the try-on clothes. Because clothes that are too loose are not easy to wrinkle, the difference in test results is not o...

Abstract

The invention discloses a testing and evaluating method for flatness of clothing in wear. At present, the testing and evaluating methods for fabric flatness are mainly carried out by comparing tested samples, which are wrinkled based on certain specific methods, with standard samples to obtain flatness levels; such testing and evaluating methods are not suitable for testing and evaluating the non-flatness of clothing caused by movements of users in actual wearing. The testing and evaluating method of the invention comprises the following specific steps of ironing fabrics, tailoring and sewing into try-on clothing, then ironing and flattening; wearing the try-on clothing by try-on personnel who moves based on rules, then collecting images in the positions of left and right elbows, left and right knees, left and right thigh ends and other heavily-wrinkled positions; clipping the wrinkled images in each collecting position, performing wavelet threshold de-noising processing on the images and extracting flatness coefficients; and calculating the comprehensive flatness coefficient of a whole set of the try-on clothing prepared from the fabrics. The computer image processing technique is adopted for testing and evaluating the flatness of clothing in wear, so that the evaluation result is more objective.

Description

technical field [0001] The invention belongs to the field of textile and garment performance testing, in particular to a testing and evaluation method for the flatness of clothing wearing. Background technique [0002] The current test and evaluation method for fabric flatness is mainly to compare the tested sample wrinkled according to the specified method with the standard sample, and judge the level of flatness, so as to characterize the quality of the fabric's wrinkle resistance. The reference standard is GB / T13769-2009, which is to adjust the humidity of the fabric after household washing and drying in a standard atmosphere, and carry out visual inspection with the AATCC three-dimensional durable pressing flatness standard photo under the specified lighting. The grade of the standard sample that is closest to the tested sample is also called DP (DurablePressing) grade. The DP grades are divided into six grades, grade 1 is the worst in flatness, grade 5 is the best, and...
