Physico-mechanical properties of kenaf pulp cellulose membrane cross-linked with glyoxal

Cellulose was extracted from kenaf core pulp (KCP) by a series of bleaching processes (D) and alkali treatment (E) in the sequence of (DEED) and pretreated with acid hydrolysis in room temperature for 6 hours. The pretreated and nontreated cellulose were dissolved in lithium hydroxide/urea (LiOH/u...
