纺织品卷烟味去除效果的评价方法

为评价家用滚筒烘干机去除纺织品吸附卷烟味的效果,更好地指导家电企业对纺织品护理产品的开发和优化,基于干衣机烘干去除卷烟味的方法及特点,建立了主观评价法和客观评价法相结合的除烟臭效果检测方法。主观评价法采用嗅觉判定6级强度法,通过研究消费者对卷烟味的可接受程度,得到除味效果的合格标准为1级及以下。客观评价法采用顶空固相微萃取/气相色谱法测定烟气特征物质(烟碱、苯酚及4-吡咯烷基吡啶)浓度的变化,同时建立了异味成分减少率作为评价指标。研究结果表明,主客观评价均可表征异味浓度的差异,且结果具有一致性,主客观相结合的方法可有效应用于清洁法去除纺织品吸附卷烟味消臭效果的评价。

Research on assessment of removing effectiveness of cigarette odor from textiles

In order to evaluate the effectiveness of domestic tumble drying on removing the cigarette odor from textiles and enable the development and optimization of textile care products that can refresh textiles,based on the principles and characteristics of laundering methods,an evaluation method on deodorization with the combination of subjective and objective assessment was established.The 6-level intensity method was used for subjective evaluation.The acceptability for cigarette odor was no more than 1 grade.As for the objective evaluation,headspace solid phase micro-extraction and gas chromatography-mass spectrometry was used for testing the concentration of typical substances(L-nicotine,phenol,4-pyrrolidinopyridine)of cigarette odor.In the meantime,deodorization rate was put forward to indicate the reduction of typical substances.According to the results of case study,both of subjective and objective evaluation method can be utilized to demonstrate the difference of odor concentration,and evaluation results of both methods turned out to be consistent.Therefore,the method with the combination of subjective and objective assessment can be effectively applied for evaluating the performance of laundering method on removing cigarette odor form textiles.
