Embodiment Construction

[0021] The dynamic angle data is obtained by using the fabric wrinkle recovery performance dynamic test system. During image acquisition, the acquisition frame rate is set to 30 frames / s for the first 30 seconds, and then the acquisition rate is set to 1 frame / s. The curve of the wrinkle recovery angle of one of the samples collected with time is as follows: figure 1 shown.

[0022] figure 1 Among them, the initial stage of the recovery angle curve showed a sharp increase, and then gradually became gentle and stable. Four types of indicators can be extracted from the curve to evaluate the wrinkle recovery performance of the sample, which reflects the recovery in the initial stage of recovery, the rapid spring stage, and the slow spring stage. by figure 1 Take the dynamic recovery angle of the sample as an example to illustrate the meaning of the dynamic evaluation index.

[0023] (1) Initial recovery rate

[0024] From figure 1 Extract the angle data in the first second ...

Abstract

The invention discloses a dynamic evaluation method of wrinkle recovery performance of fabrics, wherein the dynamic evaluation method comprises the following steps: (1), obtaining dynamic angle data by using a wrinkle recovery performance dynamic test system; and obtaining a change curve of a wrinkle recovery angle of a sample along with time; and (2), extracting four kinds of indicators from the curve of the step (1) to evaluate the wrinkle recovery performance of the sample, and reflecting recovery conditions of the recovery initial stage, acute rebound stage and slow rebound stage. The dynamic angle data are obtained through the fabric wrinkle recovery performance dynamic test system, the four kinds of indicators are obtained for evaluation of the wrinkle recovery performance of the sample. The method has the advantages of being accurate and reasonable.

Description

technical field [0001] The invention relates to the field of fabric quality detection methods, in particular to a dynamic evaluation method for fabric wrinkle recovery performance. Background technique [0002] The crease recovery performance of fabrics is an important index to measure the quality of fabrics, which not only determines the appearance of fabrics, but also affects the service life of fabrics. At present, the standard for evaluating the wrinkle recovery performance of fabrics based on the recovery angle is still the static evaluation method of measuring the wrinkle recovery angle at a specific moment. For example, the standards ISO 2313-1972, AATCC 66-2008 and GB / T3819-1997 all use the recovery process of 5min The angle of time is used as the evaluation index. However, wrinkle recovery is a dynamic process, and this evaluation method only reflects the recovery angle state of the sample at a specified moment, and cannot accurately reflect the wrinkle recovery pe...
