Textile technology includes non-woven fabric technology, modern three-dimensional weaving technology, modern electrostatic nano mesh technology, etc.
Nonwoven (English Name: nonwoven) is also known as non-woven fabric. It is composed of directional or random fibers. It is a new generation of environmental protection materials. It has the characteristics of moisture-proof, air permeability, flexibility, light weight, non combustion, rich color, low price, recyclable and so on. For example, polypropylene (PP) granules are usually used as raw materials, which are produced by continuous one-step process of high-temperature melting, wire spraying, thread laying and hot pressing coiling. It is called cloth because of its appearance and some properties.
The weaving technology of modern 3D braided composites is basically developed from the traditional textile technology. Each spindle is driven by the angle guide wheel, and transfers from one angle guide wheel to another adjacent angle guide wheel at the intersection point. The continuous repeated cycle of the process makes each spindle move in the track of the number 8 connected to each other, thus making the yarns interweave and cross each other to form a fabric.
The electrospinning device is mainly composed of three parts: spinning solution supply system and jet assembly, collecting device and high voltage electrostatic field generator. There are many factors that affect the diameter of electrospun nanofibers and the network formation mechanism, including the type of polymer, the type of solvent, the concentration of spinning solution, the electric field voltage, the distance between the jet module and the collection device, and the molding efficiency. The practice shows that the forming efficiency and net forming strength of nanofibers largely depend on the electric field strength between the jet assembly and the collecting device.
