Device and method for dynamically testing fabric quality

Abstract

The invention discloses a device for dynamically testing fabric quality. The device comprises a frame, clamps are arranged on two sidewalls of the frame, two brackets are arranged between two sidewalls of the frame, and the top of each bracket is rotatably connected with a cam; the lower part of the cam is rotatably connected with the bracket through a wheel shaft, one end of the wheel shaft extends to outside of the bracket and bonded with a transmission wheel; a motor is arranged on the frame between two brackets, a driving wheel is bonded on the output shaft of the motor, and the driving wheel is in transmission connection with two transmission wheels through transmission belts; the motor drives two cams to synchronously swing by controlling the forward rotation and reverse rotation through a cam swing control device. By simulating the use on the fabric by the hip, the elbows and the knees when the human body wears the fabric, the fabric performance and the sewing quality conditionof the fabric and the sewed fabric under the tension, the torsion, the friction and like coupling dynamics effects are synchronously detected. The invention further discloses a method for dynamicallytesting the fabric quality by adopting the device.

Description

technical field [0001] The invention relates to a device and method for inspecting and testing the quality of fabrics and fabric sewing, in particular to a device and method for dynamically testing the quality of fabrics, belonging to the technical field of textile testing. Background technique [0002] The quality of fabric and sewing is an important part of the quality of textile clothing. If the performance of fabric and sewing quality are not good, there are often appearance defects, which affect people's wearing and use, especially in the process of use due to elbow and knee joints. The parts such as the waist and buttocks are stretched and rubbed more, which will lead to loose yarn, core yarn leakage, partial breakage, and sewing slippage, cracks, damage and other quality conditions. On the one hand, it will affect the structure of the fabric, and then affect Its physical properties; on the other hand, the change of gloss will affect the appearance and color of the fab...

[0002] The quality of fabric and sewing is an important part of the quality of textile clothing. If the performance of fabric and sewing quality are not good, there are often appearance defects, which affect people's wearing and use, especially in the process of use due to elbow and knee joints. The parts such as the waist and buttocks are stretched and rubbed more, which will lead to loose yarn, core yarn leakage, partial breakage, and sewing slippage, cracks, damage and other quality conditions. On the one hand, it will affect the structure of the fabric, and then affect Its physical properties; on the other hand, the change of gloss will affect the appearance and color of the fabric; at present, the test method of the physical properties of textiles is mainly to simulate and test the physical indicators such as pilling performance, breaking strength and burs
