The effect of lithium bromide (LiBr) on the structure and properties poly (vinyl alcohol) (PVA) fibers obtained by wet-spinning was studied. tensile modulus strength a PVA fiber were greatly enhanced irrespective post-spinning hot-stretching process. high degree molecular orientation arose from reduction in crystallinity hydrogen bonding between chains solution resulting addition LiBr, which re...
