摘　　要：传统的锦纶6纤维定性筛选方法存在使用有害的酸性试剂及燃烧法需要试验人员吸入少量气体的缺点,本方法旨在探索一种仪器化的方法,以减少上述问题对试验人员的伤害。本方法采用差示扫描量热法(DSC)对锦纶6纤维的热性能进行研究,通过优化测量参数,确定了30℃/min的升温速率和称样质量范围3.5mg~10.0mg,此外研究了12种其他常见纤维对锦纶6纤维热效应的影响,发现维纶会对锦纶6纤维的定性分析产生影响,其他11种纤维聚酯(PET)、棉、苎麻、亚麻、粘胶纤维、羊毛、桑蚕丝、腈纶、醋纤、氨纶、聚乳酸纤维不会对锦纶6纤维的定性产生影响,因此本方法适用于锦纶6纤维与上述11种混纺产品的定性鉴别。The traditional qualitative methods for nylon 6 fibers involve the use of acidic reagents and combustion methods,which require the experimenter to inhale a small amount of gas.This method aims to explore an instrumental approach,to reduce the use of reagents and harm to personnel;This method uses differential scanning calorimetry(DSC)to study the thermal properties of nylon 6 fibers.By optimizing the measurement parameters,a heating rate of 30 C/min and a sample weight range of 3.5 mg~10.0 mg were determined.In addition,the influence of 12 other common fibers on the thermal effect of nylon 6 fibers was studied.It was found that vinylon has an impact on the qualitative analysis of nylon 6 fibers,while the other 1l fibers:polyester(PET),cotton,ramie,linen,viscose fiber,wool,mulberry silk,acrylic fber,acetate fber,spandex,and polylactic acid fiber will not affect the qualitative identification of nylon 6 fibers.Therefore,this method is suitable for the qualitative identification of nylon 6 fibers and the above 11 blended products.
