Description

Technical Field

[0001] The utility model relates to the technical field of textile processing, in particular to a false twister for producing polyester low-elastic yarn. Background Art

[0002] Polyester low-elastic yarn is a type of textured yarn of polyester chemical fiber. It is made of polyester chips, high-speed spinning of polyester pre-oriented yarn, and then processed by drawing and false twisting. The production and processing of polyester low-elastic yarn often adopts the false twisting deformation processing method, which is the most important physical modification method of false twisting deformation.

[0003] The false twist deformation of polyester filament is basically to produce low-elastic yarn. There are two major false twist deformation methods: rotor type and friction type. The common types of friction false twisters can be divided into several structural types such as friction disc type, rubber ring type, and ring friction type. Among them, the friction disc false twister is the most widely used type of false twister. The friction disc false twister is one of the core components of the stretch yarn machine, mainly used for false twist deformation of polyester pre-oriented yarn or drawn yarn. The structure of the friction disc false twister is mainly three-axis or six-axis, multi-disc type.

[0004] At present, when a friction disc false twister is used for production, it is necessary to select a reasonable friction disc surface speed and a thread strip entering the friction disc angle to obtain a reasonable tension at both ends, so that the thread strip tension will not increase significantly due to passing through multiple friction discs. Therefore, it is necessary to adjust the thread strip entering the friction disc angle during installation and then fix it. However, it is difficult to adjust it according to changes in production conditions after it is fixed, which is not conducive to adjusting the thread strip entering the friction disc angle to adapt to changes in production conditions, resulting in poor flexibility and practicality in production applications.
