Abstract

The invention discloses a carbon nanotube spinning machine which is used for spinning carbon nanotube films pulled out of a carbon nanotube array into carbon nanotube yarns. The spinning machine comprises a storage device, a soaking device, a false twisting device, a drafting system, a twisting collection system and a rack, wherein the storage device is used for placing the carbon nanotube array; the soaking device is used for soaking the films for shrinkage; the false twisting device performs false twisting of the carbon nanotube films; the drafting system is used for pulling the carbon nanotube films out of the carbon nanotube array; and the rack is integrated with a power system of the carbon nanotube spinning machine. According to the carbon nanotube spinning machine disclosed by the invention, the carbon nanotube films are subjected to false twisting by use of the false twisting principle of the false twisting device, and relatively long carbon nanotube yarns with better mechanical properties can be obtained; and meanwhile, large-batch industrial production can be realized.

Description

technical field [0001] The invention belongs to the micro-nano field, and in particular relates to a carbon nanotube spinning machine and a method for preparing carbon nanotube yarns by using the carbon nanotube spinning machine. Background technique [0002] Carbon nanotubes are a typical one-dimensional nanomaterial with a perfect carbon hexagonal connection structure, high strength, ultra-light mechanical properties and special electrical properties formed by a unique graphite layer structure. Its unique mechanical properties And special electrical properties have always been the concern of scientists at home and abroad. Nowadays, lightweight and high-strength material technology has become one of the main symbols to measure the national industrial level to some extent, so the unique light-weight and high-strength characteristics of carbon nanotube materials are destined to become one of the main directions of research on lightweight materials. In addition, Compared with...
