Product characteristics of electrospinning

The yarn forming principle and technology of electrostatic yarn and ring spinning yarn are different, and the yarn structure and performance have their own characteristics. Compared with ring spun yarn, electrostatic yarn has poor fiber straightness, layered structure, different modulus of each layer, more yarn modulus, poor elasticity and hard handle. The electrostatic yarn evenness is more uniform, hairiness and neps are less, and the fabric has better wear resistance and color absorption. One of the main disadvantages of electrostatic yarn is the yarn defects caused by the adhesion of fibers in the electric field shell and the hooking of fibers in the cotton conveying pipe and the taker-in roller shell. Electrostatic yarn is suitable for weaving dark jacquard serge, bed linen, furniture cloth and other products. ; It can also be used to weave jacquard tablecloth and curtain cloth, which has the advantages of clear mesh and scratch feeling. Electrostatic spinning can also spin all kinds of blended yarn, slub yarn and core-spun yarn, and weave them into fabrics with unique styles.

There are still some problems in electrostatic spinning, such as low output, many yarn defects, and no obvious improvement in labor productivity, which need further study before putting into industrial production. The research topic is: the electrical properties of fiber and reasonable electrostatic field, so as to increase the effect and control of electrostatic field on fiber and improve yarn quality and output. Make rational use of the action of airflow to reduce the interference of airflow field to electrostatic field. High-speed and efficient spinning machine can give full play to the high-yield potential of electrostatic spinning.
