Problems solved by technology

These twisting methods cannot control the twisting parameters of the nanofiber yarn due to the inability to control the eddy current of the liquid, the airflow, and the strength of the nanofibers that limit the rotation speed of the collection device.

Abstract

The invention relates to a nanofiber yarn twisting and winding device and a use method thereof. Two hollow outer rollers of a cage twisting mechanism are horizontally symmetrically arranged, and a twisting gap is formed between the rollers. The hollow outer roller is provided with air holes distributed in a matrix manner. A separation net is covered on the surface of the hollow outer roller. The hollow outer roller rotates driven by a transmission mechanism. Airflow gathering inner sleeves are respectively fixed in the hollow outer rollers. The airflow gathering inner sleeve is internally provided with an air cavity and is provided with a gas gathering port along a side surface, and the gas gathering ports are arranged in an opposite manner. The airflow gathering inner sleeves are respectively connected with air extractors. A delivery roller is corresponding to the twisting gap and is arranged on the end of the hollow outer roller. The method comprises: starting the transmission mechanism to drive the two hollow outer rollers to rotate along the same direction; starting the air extractors to respectively extract air in the two airflow gathering inner sleeves; feeding a nanofiber cluster into the twisting gap to twist, to obtain a nanofiber yarn; and the nanofiber yarn pulling and winding. The device and the method realize to regulate nanofiber yarn twisting parameters, and improve stability of a twisting process.

Description

technical field [0001] The invention belongs to the technical field of yarn twisting and winding, and in particular relates to a nanofiber yarn twisting and winding device and an application method thereof. Background technique [0002] The biggest feature of nanofibers is small diameter and large specific surface area. As the diameter of the fiber becomes thinner, the number of surface atoms, surface tension and surface energy increase sharply, thus showing specificity in physicochemical aspects. Therefore, trying to combine nanotechnology with the traditional textile industry in order to improve the status quo of the textile industry and process functional textiles with high added value has been the goal of many textile research scholars and fiber scientists. There are many ways to prepare nanofibers, and the processing technology of electrospinning is simple. Since Anton formhals obtained the US patent in 1934, this method of spinning with the help of electrostatic field ...
