A method for determining the presence of an odorous material on a fabric includes applying a benzofurazan indicator to the fabric, tagging the odorous material with the indicator, exposing the fabric to a light at a predefined wavelength to produce fluorescence of the tagged odorous material, and observing the fluorescence of the tagged odorous material through a bandpass filter. Also disclosed is a system including the fabric, the indicator applied to the fabric and configured to tag the odorous material, at least one light source arranged about the fabric and configured to direct light on the fabric to produce fluorescence of the tagged odorous material, and an imaging device arranged about the fabric to capture an image of the fabric through a bandpass filter with the image including at least one illuminated portion representing the tagged odorous material. Also disclosed is a method for determining the efficacy of a laundry product.
一种确定织物上是否存在气味物质的方法包括:在织物上涂抹
苯并呋喃指示剂,用指示剂标记气味物质,将织物暴露在预定波长的光线下以产生被标记气味物质的荧光,以及通过带通滤波器观察被标记气味物质的荧光。还公开了一种系统,包括织物、应用于织物并被配置为标记气味物质的指示剂、围绕织物布置并被配置为将光照射到织物上以产生标记气味物质荧光的至少一个光源,以及围绕织物布置以通过带通滤波器捕获织物图像的成像装置,图像包括代表标记气味物质的至少一个发光部分。还公开了一种确定洗衣产品功效的方法。
