Test device and method for simulating bulging property of fabric in actual wearing

Abstract

The invention discloses a test device and method for simulating the bulging property of fabric in actual wearing. The bulging deformation produced by a common method for testing the bulging property of fabric is way different from the bulging shape produced in actual wearing. According to the device, a wood ball and a spring are connected to the arc grooves of a front wooden stick and a rear wooden stick to form a simulative arm; the outer layer of the simulative arm is coated with cotton, and knitted fabric wraps the cotton and is sutured; the U-shaped movable arm is fixed on a peripheral baffle plate by a crew and a nut; the rear wooden stick is placed in the peripheral baffle plate; and the front wooden stick is placed into the U-shaped movable arm. The method for testing bulging property of fabric is as below: ironing and cutting the fabric, scanning an image before bulging, and then fixing the fabric to a joint simulation device, arranging the joint simulation device on a bending and fixing device, and taking out and flattening the fabric after a preset time; acquiring the bulging image of the worst affected area of the fabric; and processing the images before and after bulging to obtain a residual bulging image, and extracting features and calculating the rate of bulging. The bulging deformation produced by the device is similar to the bulging shape in actual wearing.

Description

technical field [0001] The invention belongs to the field of textile and garment performance testing, and in particular relates to a fabric camber test device and method for simulating actual wearing. Background technique [0002] Clothing arching is a very common phenomenon that occurs in people's daily life. Clothes worn by people will be arched and deformed during activities, and parts with greater range of motion are more prone to arching, such as elbow joints and knee joints. These common arching and deformation phenomena have a great impact on the wearing effect of clothing, greatly reduce the aesthetics, and also directly affect the appearance and flatness. At present, the common test methods for fabric cambering are: (1) sphere cambering method; (2) using an electronic tensile measuring instrument to indirectly express the cambering property of fabrics by performing a dynamic tensile test on the vertical and horizontal directions of the fabric. However, there is a l...

Problems solved by technology

However, there is a large gap between the arching deformation produced by these two methods and the arching shape of the garment during the actual wearing process, so the test results cannot truly reflect the arching of the fabric during the actual wearing process
