Abstract
In order to prepare micro and nanofibrils from jute the binder has to be cleaned off A new technique including chemical room temperature alkaline acid steam and 80 °C alkaline and physical high pressure steam treatments of natural fibers was developed The effects of chemical and physical treatments on the morphological development of jute fibers from micro to nanoscale were observed by using scanning electron microscopy SEM This novel natural fibers treatment technology has two advantages compared with others One is the long strands of natural fibers keep their length by special acid steam treatment but the traditional acid solution treatment makes the length of natural fibers short Another one is the high pressure steam treatment that made jute fibers nanofibrils The thermal property of untreated and treated fibers was determined by using thermogravimetric analysis TGA which indicated that the thermal stability of the jute fibers was enhanced after treatments The lignin acted as binder was mainly removed by analyzing solid residues using fourier transform infrared spectrometer FTIR
