摘要
纺织品纤维成分和含量检测是纺织品检测里最基本的检测项目之一。当前广泛采用的各纤维检测方法一般都需要制样、人工判断检测等步骤,检测效率不高。旋转线偏振光成像方法是一种基于多角度入射线偏振角和出射检偏角组合测量的新方法,经拟合可以得到入射线偏振角和出射检偏角之间的函数关系式,并从中提取与纤维微结构相关的一个特征参量。利用该参量值和分布的不同,能够比较明显地区分常见的纺织品纤维。在单成分纤维测量结果的基础上,该方法还具有对混纺纤维进行成分和含量检测的可行性。这是一种检测纤维成分的新方法,具有无损、在体、快速检测的特点。
Measurement of the fiber composition and content is important for textile testing. At present, the widely used testing methods require complex sample preparation and rely on the subjective judgment, which decreases testing efficiency. The rotating linearly polarized light imaging method is based on multi-incident and detection polarization angles images. By fitting the polarization difference as function of these multi-incident and detection polarization angles, a characteristic parameter related to fiber microstructure is obtained. The common textile fibers can be easily discriminated by this characteristic parameter. Based on the measurement results of single component fiber, it is feasible to detect the component and content of blend fibers by this technique. This technique has the advantage of non-destructive operation, in vivo testing, and rapid speed.
