Embodiment Construction

[0031] Such as figure 1 As shown, a yarn twist shrinkage performance testing device of the present invention includes a base 5 and a support frame 6, the base 5 and the support frame 6 can adopt an integrated structure or a split structure, and a stepping motor is installed on the support frame 6 3. A pneumatic clamp 2 is connected to the lower end of the stepping motor 3, one end of the yarn 1 is connected to the pneumatic clamp 2, and the other end of the yarn 1 is connected to a tension controller 4.

[0032] The control device 7 is connected with the stepping motor 3, and the direction of rotation, the speed of rotation and the number of rotations of the stepping motor 3 are controlled and regulated by the control device 7. By controlling the direction of rotation, the speed of rotation and the number of rotations of the stepping motor 3, Realize the coordinated rotation of the pneumatic clamp 2; in this embodiment, the control device 7 preferably selects a single-chip mic...

Abstract

The invention discloses a yarn twist contraction performance test method and device. The device comprises a base and a support. A stepping motor is installed on the support. A pneumatic clamp is connected to the lower end of the stepping motor. One end of yarn is connected to the pneumatic clamp and the other end of the yarn is connected to a tension controller. One end of the yarn is fixed through the pneumatic clamp, the other end of the yarn is not fixed and a yarn tension force is controlled only through a yarn controller so that the problem that the traditional method fixes two ends of the yarn so that yarn strength is reduced and a test result is furthermore is solved. The method and device have operation simpleness and convenience and produce an accurate test result.

Description

Technical field: [0001] The invention relates to a method and device for testing the twist shrinkage performance of yarns, in particular to a method for testing the twist shrinkage performance of yarns according to the twist shrinkage characteristics of yarns. Background technique: [0002] Twist structure is a relatively old and important research topic for staple fiber yarn and filament yarn. With the development of science and technology, its research is still making progress and obtaining unexpected application results. For example, in recent years, there have been Very popular strong twist yarn and weak twist yarn products, etc. As early as 1907, Gegauff conducted an effective analysis of the yarn structure and proposed the theory of the structure of spun yarn and filament yarn. From 1922 to 1930, Barker, Herzog, Skinkle, etc. conducted research on the evaluation of yarn twist. In 1928, BallS proposed two forms of yarn twisting methods: the twisting method of cylindri...
