Integrated detection method and device of rigidity, flexibility and wrinkle resistance of fabrics

Abstract

The invention discloses a method for detecting fabrics, in particular an integrated detection method and an integrated detection device of the rigidity, flexibility and wrinkle resistance of the fabrics. The device is characterized by comprising a detection platform, wherein the detection platform is made of a transparent material and comprises a plane plate and a vertical plate which is vertically arranged in the middle of the plane plate; one side of the vertical plate is a cloth carrying table, and the other side of the vertical plate is provided with an image pickup device; a sliding plate is arranged on the cloth carrying table in a movable manner and can slide along the length direction of the cloth carrying table; and measurement devices are arranged at two ends, along the length direction, of the cloth carrying table. The invention has the advantages of simple operation and high detection accuracy.

Description

Technical field: [0001] The invention relates to a fabric detection method, in particular to an integrated detection method of rigidity, flexibility and wrinkle resistance of a fabric and a device thereof. Background technique: [0002] Rigidity and flexibility refer to the bending stiffness and softness of fabrics. Flexural stiffness refers to the ability of a fabric to resist changes in its shape when bent, and is often used to evaluate the opposite property - softness. The rigidity and flexibility of fabrics directly affect the shape and fit of clothing. Generally, underwear requires good softness to make it fit and comfortable to wear, while outerwear requires a certain degree of rigidity to make the shape crisp and tangible. There are many factors that affect the rigidity and flexibility of fabrics, including the bending properties of fibers, the structure of yarns, the tissue characteristics of fabrics and finishing, etc. [0003] The national standard stipulates two...

AI Technical Summary

Problems solved by technology

[0006] First, the current evaluation of fabric rigidity, flexibility and wrinkle resistance requires two instruments to evaluate separately, which greatly affects the test efficiency, and rigidity, flexibility and wrinkle resistance are closely related. If one instrument is used to solve the problem, the detection efficiency can be greatly improved

[0007] Second, the price of traditional testing instruments is relatively high, and most textile enterprises generally do not purchase them out of cost reduction considerations, which in turn affects product performance testing

[0008] Third, the traditional rigid-flexible testing adopts the slope method and the heart-shaped method in a stable state, but the complex stress changes during the use of fabrics are not considered, and the evaluation method does not conform to the actual use environment

[0009] Fourth, the subjective evaluation method of wrinkle resistance The method uses human subjective judgment to evaluate the wrinkle condition of the fabric, and the deviation is relatively large, especially when the DP value reaches above 3.5, the difference between the samples is very small. It is more difficult to judge

There are two problems in the general measurement method GB / T 38l9-l997 and AATCC66-2003 in the objective evaluation method. One is that the measurement accuracy is difficult to guarantee

The error of the instrument and the reading is relatively large. Second, there is a certain gap between the measurement method and the actual use situation. In the actual use process, because the wrinkle condition of the fabric is usually three-dimensional, the method of measuring the wrinkle recovery angle of the fabric is only one direction. Therefore, the test results may not accurately reflect the wrinkle resistance of the fabric
