【摘要】 <正>长绒棉纤维具有长、细、强的特性,是纺高支棉纱和特纺工业的重要原料,有特殊使用价值。由于新疆独特的自然气候条件使之成为全国唯一的长绒棉生产基地。对长绒棉的结构及改性的研究将会对其应用有一定的指导意义。常德华等人做过辐射对棉纤维结晶度更多还原

【Abstract】 Changes of aggregate state and microstructure of Long-staple cotton fiber before and after irradiation were studied by solid state ¹³C CP/MAS NMR and ESR spectra.The results show that the aggregate state and microstructure were changed with increasing of irradiation time,while the crystallization and hydrogen-bonded of Long-staple cotton fiber changed by irradiation.It also shows that different free radicals appear after irradiation and their concentration increases with the increase of irradiation time.更多还原
