Herbal plants have been used in medicine since ancient times due to their health benefits. The research in this field continues to reveal advantages of these plants such as antibacterial activity against multidrug-resistant bacteria and possibility to integrate extracts in fibers by electrospinning. Electrospinning is a simple, yet versatile method of creating polymer-based nanofiber web, which can be used for wound dressings, tissue engineering and drug delivery systems. In production of electrospun nanofibers a solution of biocompatible polymer and a plant extract is needed. Therefore exploration of such composition ingredients is important. [ABSTRACT FROM AUTHOR]

The Research aim is to find the most time and energy economic treatment of natural fibres to obtain micro and nanofibres. Alkaline treatment, steam explosion autohydrolysis and ultrasonic treatment effect on hemp fibres and shives dimensions were examined. Fibres length, diameter, form factor and sifting amount were analyzed. The results of the analysis show that an increase in treatment intensity gives a higher amount of fibres being noticeably shorter and thinner than the untreated dew-retted fibres. Fine content of fibres and shives increases, when treatment intensity increases. [ABSTRACT FROM AUTHOR]
