Problems solved by technology

Therefore, the larger the twisting triangle area, the easier it is to cause fiber breakage, which makes it difficult to control the basic parameters of the yarn (yarn twist, yarn forming speed, fineness, evenness, strength, etc.), resulting in yarn breakage, It is difficult to form yarn continuously and cannot be prepared in batches

Abstract

The invention relates to an orientation bundling device, an electrostatic spinning device and a nanofiber yarn preparation method. The orientation bundling device comprises a negative pressure fiber collecting roller, a motor, a communicating device and an exhaust device. Air holes are formed in the surface of the negative pressure fiber collecting roller, the negative pressure fiber collecting roller is drive by the motor to rotate, air is exhausted through the exhaust device to form negative pressure, the electrostatic spinning device further comprises a spinning nozzle, a high pressure electrostatic generator, a sliding rail, an automatic liquid supply device and a twisting winding device, spinning solution jet generated by jetting of the spinning nozzle is received by the negative pressure fiber collecting roller, nanofiber is gathered under the dual effects of high-speed rotation of the negative pressure fiber collecting roller and the negative pressure airflow and achieves orientation in the air hole distribution direction, nanofiber bundles are pulled from the negative pressure fiber collecting roller to the twisting winding device to be twisted and wound to obtain continuous orientation nanofiber yarn. The influence of a twisting triangle region can be effectively weakened, basic parameters of the yarn can be stably controlled, the quality of the nanofiber yarn can be improved, and the yield of the nanofiber yarn can be increased.

Description

technical field [0001] The invention belongs to the technical field of electrospinning, and in particular relates to an orientation clustering device, an electrospinning device and a method for preparing nanofiber yarns. Background technique [0002] Electrospinning is currently the most common technology for spinning nanofibers. Its products have excellent properties, such as a large specific surface area, flexible surface functionalization and excellent mechanical behavior, etc., which can be applied To tissue engineering, wound dressings, drug release, filter materials, composite reinforcements, sensors, etc. Since the electrospinning process is simple, the preparation process is shorter than conventional spinning, and the products have excellent functions, since Anton formhals obtained the US patent in 1934, electrospinning has been the goal of fiber scientists and textile developers for a long time. This kind of nanofiber will become the leading product of our country ...
