Abstract
Cotton-candy meltblown process was adopt for polybutylene succinate nonwoven production with ultra-fine fiber, in order to utilize as a barrier and support some efficiency of main product. For sample preparation, melt-spinning condition of meltblown process was set according to verification of thermal properties such as thermal behavior (DSC) and melt flow index (MFI). Spinning temperature, hot-air jet, distance from spinneret to collector and collector speed were fixed while adjustment of screw speed was increased for observing processability. Result suggested that tendency of mass flow rate affected on formation of ultra-fine fiber in nonwoven structure including distributed fiber, basis weight and air permeability. Therefore, a concept of eco-friendly nonwoven from biobased polymer could be expand into commercial manufacture.
