摘　　要：为开发差别化涤纶染色织物,采用CO_(2)激光对织物进行预处理和后整理改性。以K/S值为指标,研究预处理和后整理参数对织物轧染染色性能的影响,并确定预处理、后整理改性工艺。测试纤维的表面形态、热稳定性和结晶度,分析激光对染料热迁移性能和对染料最大吸收波长的影响,测试织物色牢度和断裂强力。结果表明:优化的预处理和后整理改性工艺为功率12 W、速度150 mm/s、步距0.2 mm,分散藏青SFN对预处理和后整理改性织物染色后K/S值分别提高44.89%和38.41%;激光改性使纤维表面产生刻蚀,结晶度下降;激光改性对纤维的热稳定性和染料的最大吸收波长没有影响;激光后整理使染色纤维内部染料发生热迁移;改性前后织物的色牢度基本不变,均达到4级及以上,断裂强力稍下降。In order to develop differentiated polyester dyed fabrics,CO_(2)laser was used to pretreat and finish fabrics.Taking the K/S value as the index,the effects of pretreatment and finishing parameters on pad dyeing properties of fabrics were studied,and the pretreatment and finishing modification processes were optimized.The surface morphology,thermal stability and crystallinity of the fiber were measured.The effects of laser on the thermal mobility of dyes and the maximum absorption wavelength of dyes were analyzed.The color fastness and breaking strength of dyed fabrics were tested.The results show that the optimized pretreatment and finishing process is power 12 W,speed 150 mm/s and step distance 0.2 mm.The K/S value of laser pretreatment and finishing modified fabrics dyed by dispersed dark green SFN are increased by 44.89%and 38.41%,respectively.The surface of the fiber is etched by laser modification,and the crystallinity decreases.Laser modification has no effect on the thermal stability of the fiber and the maximum absorption wavelength of dyes.After laser finishing,the dye in the fiber is thermally transferred.The fastness of the fabric before and after modification is basically unchanged,all reaching grade 4 or above,but the breaking strength decreases slightly.
