**1.3. Long and continuous fiber [15]**

The electrospinning process usually produced long nanofibers as any other traditional nonwoven processes did; so scholars claimed electrospinning as a continuous nanofiber manu‐ facturing method. In Beachley V's results [15], an electrospun polycaprolactone (PCL) fiber had a length ranging from 30 to 50cm, which is close to that of melt-blown nanofiber lengths obtained by Christopher J. Ellison [16]. This high draft ratio is attributed to the principle of electrospinning: electromicro stretch. Traditional industrial spinning fiber is stretched from one end. All the molecular chains between the spinning pool and the jet end are stretched by the force transferring from its end, as shown in Figure 3a. However, the driving force of polymer chains in electrospinning is different; not from the end, but between the adjacent charges which endure a repulsion or attracting force in the electric field, shown in Figure 3b. In this way, an electrospinning jet represents an equilibrium state in a tug of war between 2. Author details: Scientific Title: Dr Full Name:Haoyi Li Affiliation:

Non-woven fabrics produced by nanofibers may have eliminated the falling out of short fibers and hence avoid some potential pollution of nanomaterials. 1
