双组分纤维织物光谱图数据库的建立及其优化

Optimization method for establishing the spectrogram database of two component fiber fabric

为监督和提高纺织品内在质量、推广纤维含量快速检测技术,文章研究建立双组分纤维织物光谱图数据库并对其进行优化。由于纺织品使用的纤维种类多、混纺比复杂,建立光谱数据库困难较大,从而制约了光谱检测技术在纺织品检测中的推广应用。通过统计服装面料成分得到常见双组分纤维织物的混纺比例范围,根据GB/T 29862—2013中纤维含量的允许误差范围,提出了在混纺比例范围内分段建立光谱图的方法。研究结果表明:采用划定纤维混纺比范围的方法剔除非常规纤维混纺比例范围,可减少光谱数据库建立的工作量,加速红外光谱以及拉曼光谱快速检测技术的推广,扩大服装纤维含量的检测范围。

The popularization of rapid fiber content detection technology is beneficial to the supervision and improvement of the internal quality of textiles.Because there are many kinds of fibers used in textiles and the complexity of blending ratio,it is difficult to establish a spectral database in the early stage,which restricts the popularization of spectral detection technology.According to the allowable error range of fiber content in the national standard GB/T 29862—2013,the method of building spectral diagram in the range of blending proportion was proposed.The results showed that adopting the method of defining the range of fiber blending can eliminate the range of unconventional fiber blending and reduce the workload of establishing the spectrogram database.It can accelerate the promotion of the rapid detection technology of infrared spectrum and Raman spectrum and expand the detection range of clothing fiber content.
