Preparation and Characterization of Electrospun Lauric Acid/polyethylene Terephthalate Nanofibers/Woven Composite Fabrics with Heat Preserved Property
摘要
Abstract
This work was focused on preparation and characterization of the electrospun lauric acid (LA)/polyethylene terephthalate (PET) nanofibers/woven composite fabrics.Composite fabrics consisting of electrospun LA/PET nanofibers and woven fabrics were prepared by quilting a sandwich structure.Cotton yarns,wool yarns,polyester-cotton yarns,acrylic yarns and polyester yarns were selected to prepare the woven fabrics in laboratory,respectively.Meanwhile,nanofibers with fatty acids of LA encapsulated in supporting matrices of PET were prepared through electrospinning technique.Morphological structures of the nanofibers were characterized by scanning electron microscope (SEM),and their thermal energy storage properties were investigated by the differential scanning calorimeter (DSC).In addition,the relationships between heat preserved properties of the composite fabrics and LA/PET mass ratios,woven structures and woven materials were discussed,respectively.The results showed that the LA/PET nanofibers possessed smooth and cylindrical morphological structure,LA and PET had good miscibility in those nanofibers.Enthalpy values associated with melting and crystallization for LA encapsulated in nanofibers were lower than corresponding theoretical values,but it had no appreciable effect on the phase change temperatures.Heat preserved property of composite fabric measurement suggested that all of those composite fabrics had much more insulation than the original one,meanwhile,the thermal cycling test indicated that they had a good thermal reliability.关键词
