Abstract
Four metal salts such as calcium chloride,lithium chloride,copper chloride and zinc chloride were selected and prepared into solutions by using deionized water and anhydrous ethanol as solvents respectively,and polyamide 66 fiber was conducted complexation modification.The effects of different metal salts and their sol-vent types on the structure and properties of polyamide 66 fiber was investigated by using FTIR,DSC,XRD,SEM,and single fiber stretching.The results showed that after treatment with the four metal salts,copper chloride had the greatest effect on the structure and properties of polyamide 66 fiber and the strongest complex-ation effect on the fiber while zinc chloride had the least effect on the structure and properties of polyamide 66 fi-ber.Calcium chloride and lithium chloride had the medium effects,which was manifested by the shift of N-H vi-bration peak to low wave number in infrared spectra,the decrease of melting temperature,crystallinity and tensile breaking strength.When calcium chloride was selected as metal salt complexing agent,the effect of ethanol as a solvent on the structure and properties of polyamide 66 fiber was greater than that of water,indicating that ethanol facilitated the formation of complexation between metal ions and fiber.关键词
