Abstract

The invention relates to a fiber untwisting and shaping device, preparation device and method. The untwisting and shaping device is used for shaping semi-finished fibers, the semi-finished fibers are obtained by twisting and heat treatment of nascent fibers, the shaping device comprises an untwisting assembly and a stretching and shaping assembly, the untwisting assembly is used for untwisting the semi-finished fibers, and the stretching and shaping assembly is used for stretching and shaping the semi-finished fibers. The stretching and shaping assembly is used for carrying out stretching and shaping treatment on the untwisted fibers, wherein the untwisting assembly comprises a winding drum, a guiding untwisting drum and a rotating part; the semi-finished fiber is wound on the winding drum; the guiding untwisting drum is provided with a cavity, and the winding drum is located in the cavity; and the rotating part is used for driving the winding drum and the guiding untwisting drum to rotate. The fiber untwisting and shaping device is simple in structure, easy and convenient to operate, free of damage to fibers and capable of achieving effective untwisting.

Description

technical field [0001] The invention relates to the preparation of fibers, in particular to the untwisting shaping and preparation of a rigid fiber. Background technique [0002] During the processing of rigid fibers, high temperature heat treatment is often required to improve the strength of the fibers. There are two ways of high temperature heat treatment: continuous and batch. Some fibers can only be intermittently subjected to long-term vacuum or high-temperature heat treatment in an inert gas environment, while continuous high-temperature heat treatment cannot achieve the desired effect, such as polyimide fibers and polyarylate fibers, which require several hours of high temperature heat treatment. There are also some rigid fibers that can be subjected to continuous high-temperature heat treatment, such as polyparaphenylene terephthalamide fibers; Different, suitable for different use requirements. [0003] However, whether it is continuous or batch, during the hig...
