Problems solved by technology

However, the shape retention of textiles is the result of the interaction of fiber aggregate materials such as internal fibers or yarns, and is an external manifestation of the mechanical properties of textile materials. Moreover, the shape retention of textiles is not only reflected in wrinkles and smoothness, but also involves the texture of textiles. Tensile resilience, compression resilience and other properties, but there is currently a lack of comprehensive and rapid testing devices and methods for textile shape retention

Embodiment 1

[0035] Adjust the horizontal distance between the fixed plate 41 and the moving plate 42 to be 3 cm, and the length * width is 4 cm * 4 cm. The woven fabric is clamped on the first elastic clamp 43 and the second elastic clamp 44, and then An elastic clamper 43 and a second elastic clamper 44 form a natural suspension state; then drive the movable plate 42 to move horizontally to the left through the transmission mechanism 6 until the force sensor shows 50cN, the movable plate 42 stops moving to the left and continues The moving plate 42 is driven to move rightward from the maximum compression displacement by the transmission mechanism 6 until the force value of the force sensor 45 reaches -60cN, and the moving plate 42 stops moving to the right and starts to return to the left until the moving plate 42 reaches the initial position set in the experiment The stop motion test is completed. At the same time, the force sensor 45 collects the original data of the test process to obt...

Abstract

The invention provides a textile shape retention measurement device. The device comprises a base, a first support plate fixedly arranged on the base, a detection mechanism and a drive mechanism, wherein the detection mechanism comprises a fixed plate, a moving plate, a first elastic holder embedded in the fixed plate, a second elastic holder embedded in the moving plate and a force sensor; the fixed plate and the moving plate are parallel with each other and both perpendicular to the base; the force sensor is connected with the fixed plate and the first support plate through a first connectingpiece and a second connecting piece; the moving plate is connected with the drive mechanism; the drive mechanism can control the moving plate to move in the direction perpendicular to the moving plate. The invention also provides a textile shape retention measurement method based on mechanics. By use of the device and the method, measurement evaluation of bending crease resilience, compression resilience and tensile resilience of textile can be finished once through mechanical measurement.

Description

technical field [0001] The invention relates to the technical field of precise measurement of textiles, in particular to a measurement technology of the shape retention of textiles. Background technique [0002] The shape retention of textiles is an important attribute of textiles in the process of processing, use and maintenance. It involves many aspects such as bending shape retention, tensile shape retention and compression shape retention of textiles. It is the comprehensive effect of the physical and mechanical properties of textiles. . Good shape retention has become a basic requirement for high-quality textiles, and an objective measurement of textile shape retention is necessary. [0003] At present, the measurement of the shape retention of textiles is mainly to evaluate the crease recovery of textiles through the crease recovery angle of textiles, so as to characterize the shape retention of textiles; the other is according to the AATCC124-2011 standard, through t...
