Clothing arching testing device and clothing arching testing method

Abstract

The invention discloses a clothing arching testing device and a clothing arching testing method. At present, a common fabric arching test method is a steel ball jacking test sample method, and although the method measures arching residual deformation, arching deformation generated in the actual wearing process of clothes cannot be completely simulated. The device comprises a flexion and extensiondriving module, a rack and a leg simulation mechanism, the flexion and extension driving module comprises a single-side flexion and extension assembly, an air cylinder and a driving rod. The leg simulation mechanism comprises a flexible sleeve, a shank supporting rod, a thigh supporting rod, an inflatable air bag and a hook-and-loop fastener. The flexible sleeve is sleeved on the shank supportingrod and the thigh supporting rod and consists of a shank sleeve, a thigh sleeve and a connecting sleeve which are connected in sequence; knee movement can be simulated, and the arching condition of the fabric when the fabric is subjected to various external forces can be reproduced. According to the method for evaluating the arching performance of the fabric, a plurality of indexes capable of reflecting the arching degree are obtained through an image processing technology, and the arching grade can be predicted according to the established linear model.

Description

technical field [0001] The invention belongs to the technical field of textile and garment performance testing, and in particular relates to a testing device for garment arching and a testing method thereof. Background technique [0002] With the continuous improvement of living standards, people's requirements for clothing have also changed, from the initial durability to the current aesthetics and comfort. In the process of production and wearing, the fabric is often subjected to various external forces, causing the shape of the garment to be out of shape, which seriously affects the appearance of the garment. In order to avoid this phenomenon as much as possible, improving the shape retention of fabrics has become an important research direction in recent years. Shape retention is an important index to measure the quality of clothing. The arching of clothing fabrics is a typical fabric deformation phenomenon. The arching is the result of repeated external forces on knees...

Problems solved by technology

At present, the common test method for fabric arching is the steel ball top pressure test method. Although this method measures the residual deformation of the arching, it cannot completely simulate the arching deformation of the garment during the actual wearing process.

In order to obtain more realistic arching deformation data, a real person try-on experiment can also be carried out, but this method has individual differences, the results are not representative, and the artificial experiment requires a lot of repetitive squatting movements, which is also a challenge for the experimenter himself. burden
