The effect of kenaf core and bast mixing on soda pulping and paper strengths

Paper industry has been experiencing growing shortage of cellulosic material over the last decades. As a fast-growing plant, kenaf has good potential to compensate wood shortages taking into account its long historical record of cultivation in Iran. Kenaf variety of 432 was collected from Varamin re...
