摘要:

为开发具有消臭功能的涤纶织物,采用β-环糊精(β-CD)为消臭剂,以消氨值为指标,研究了锚固涤纶织物的消臭效果,分析了β-CD、柠檬酸(CA)和消臭时间对整理织物消臭效果的影响。测试了消臭涤纶织物的耐洗性能,借助扫描电子显微镜和红外光谱仪对整理前后涤纶织物的结构进行分析。结果表明:本文实验范围内β-CD的最大锚固量为57.36 mg/g,β-CD(质量浓度为60 g/L)锚固织物的包合消氨时间为14 h,消氨值可达 4.442 5 mg/g,水洗15次后的消氨值仍为未整理织物的64倍,耐洗性较好;涤纶表面有明显的β-CD负载,表面氧元素含量明显增加,羟基含量增加。

Abstract:

In order to develop polyester fabrics with deodorizing function, β-cyclodextrin (β-CD) was used as the deodorant, and the anchored polyester fabric was studied with the ammonia elimination value as an indicator. The deodorizing effect of β-CD, citric acid (CA) and deodorizing time on the deodorizing effect of finishing fabrics were analyzed. The water wash resistance of the deodorized fabric was tested. The scanning electron microscopy and infrared spectrometer were adopted to characterize the polyester fabric before and after finishing. The results show that the maximum anchorage of β-CD in the experimental range is 57.36 mg/g. The β-CD (mass concentration is 60 g/L) anchoring fabric has the combined ammonia elimination time of 14 h and the ammonia elimination value of 4.442 5 mg/g. After 15 cycles of washing, the ammonia elimination value of the fabric is 64 times of the unfinished fabric, and the washing resistance is good. The polyester fiber surface has the obvious loading of β-CD, and the oxygen element content increases significantly. The infrared spectra indicates an increase in the hydroxy content of the fiber after finishing.

Key words: β-cyclodextrin, citric acid, polyester fabric, deodorization finishing
