摘要
采用咪唑类阳离子Gemini表面活性剂2-溴-1-(1-亚正丁基-3-正癸基咪唑)-1-正癸基咪唑(简称10-4-10)和2-溴-1-(1-亚正丁基-3-正己基咪唑)-3-正己基咪唑(简称6-4-6)作为麂皮绒开纤促进剂,探究了促进剂和氢氧化钠用量,开纤温度和时间对麂皮绒开纤效果的影响,并与传统促进剂十二烷基二甲基苄基氯化铵(1227)做对比,测试了麂皮绒织物的开纤率和厚度,并对开纤前后的织物形貌进行SEM表征。结果表明,10-4-10对麂皮绒织物的开纤促进效果优于1227,6-4-6对麂皮绒的开纤促进效果有限。10-4-10对麂皮绒的低碱开纤最佳工艺为:促进剂10-4-102.5×10^(-4)mol/L,NaOH 10 g/L,开纤温度100℃,开纤保温时间40 min左右。在麂皮绒织物开纤整理液中加入促进剂10-4-10能有效提高麂皮绒的开纤率,同时降低NaOH用量;通过SEM表征可知麂皮绒织物的开纤效果明显。
Cationic imidazole-based Gemini surfactants 2-bromo-1-(1-isoamyl-3-nonyl imidazole)-1-nonyl imidazole(10-4-10)and 2-bromo-1-(1-isoamyl-3-hexyl imidazole)-3-hexyl imidazole(6-4-6)are used as the accelerants for the splitting of suede fabric.The effects of accelerant dosage,sodium hydroxide dosage,splitting temperature and time on the splitting results of suede fabric are investigated,and compared with the traditional accelerant dodecyl dimethyl benzyl chlorohydrin(1227).The splitting rate and thickness of the suede fabric are tested,and the morphology of the fabric before and after splitting is characterized by SEM.The results show that splitting promotion effect on suede fabric with10-4-10 is better than 1227.6-4-6 has limited splitting promotion effect on suede fabric.The optimal low-alkali splitting process with 10-4-10 for suede fabric is accelerant 10-4-102.5×10^(-4)mol/L,NaOH 10 g/L,splitting at 100℃ for 40 min.Using 10-4-10 as accelerant in splitting treatment of suede fabric can effectively increase the splitting rate of suede fabric and reduce the NaOH dosage.SEM characterization shows that the splitting effect of suede fabric is significant.
