Abstract

The invention relates to a device for preparing electrospinning nanofiber core-spun yarn and its application, comprising: a twisting device, an unwinding device, a winding device, a double-needle electrospinning device and a control system. The present invention also provides a method for preparing electrospun nanofiber core-spun yarn: the prepared spinning solution is spun through a double-needle electrospinning device, so that the nanofibers are deposited on the metal funnel and the core yarn, and the metal funnel rotates to The nanofiber is evenly wound on the core yarn moving at a constant speed, and finally forms the nanofiber core-spun yarn with the nanofiber as the cortex; the present invention also provides another preparation method of the nanofiber fabric, comprising: using water-soluble yarn as the core yarn , the nanofiber core-spun yarn is prepared by the above method; the core-spun yarn fabric is prepared by textile technology; the core yarn is dissolved to obtain the nanofiber fabric. The invention has high operability, the device has a novel structure, and the arrangement of nanofibers on the surface of the core-spun yarn has high controllability.

Description

Technical field

[0001] The invention belongs to a nanofiber device and its application, and particularly relates to an electrostatic spinning nanofiber core-spun yarn device and its application. Background technique

[0002] Electrospinning is under the action of a high-voltage electric field, the polymer fluid will be gradually thinned by the electric field force, forming ultra-fine fibers, the fiber diameter ranging from tens of nanometers to several microns. In the process of electrospinning, the polymer fluid will produce directional motion under the action of electric field force, and the charged body will be subjected to the electric field force perpendicular to the fluid when moving in the electric field, which will cause bending instability, and its motion range will eventually form a three-dimensional cone 形区。 Shaped area. The nanofibers are arranged in disorder during the forming process, forming a non-woven fiber mat on the receiving device. Nanofiber felt has a large...
