Electronic nose technology-based fabric fragrance persistence characterization quantitative method

Abstract

The invention discloses an electronic nose technology-based fabric fragrance persistence characterization quantitative method, which comprises the following steps of: firstly, screening an electronicnose gas sensitive sensor to obtain perfume in an appropriate proportion; secondly, optimizing sealing time through a control group test; thirdly, optimizing volatilization time through a control group test; and then, uniformly dripping the same amount of perfume on the fabric with the same parameters, opening the fabric for the volatilization time, and sealing the fabric for the same sealing timeby using a preservative film; sampling headspace gas in the beaker by adopting an electronic nose to obtain a gas sensitive sensor array response value of the odor in the fabric along with time change; finally, using SPSS software to carry out curve fitting on the response value data, and therefore achieving quantitative characterization of the fragrance retention performance of the fabric. According to the method, the fragrance persistence of the fabric is quantitatively analyzed through an electronic nose and a headspace technology, the problems of long consumed time, incapability of real-time detection and the like of physicochemical method detection on fabric fragrance characterization are solved, and quantitative description on the fragrance persistence of the fabric is realized.

Description

technical field [0001] The invention belongs to the field of fabric odor detection, and in particular relates to a quantitative characterization method for fabric fragrance persistence performance based on electronic nose technology. Background technique [0002] Nowadays, perfume has been widely used in people's daily life. It delights the user and impresses others. At the same time, it can mask bad odors such as sweat and body odor. In addition, it is reported that spices have sedative, bactericidal, hypnotic, health care and other functions. However, spraying perfume directly on the skin may cause skin diseases such as allergies. Therefore, perfume is more suitable for spraying directly on clothing. [0003] As a new testing project, the detection of aromatic textiles is in the stage of continuous exploration and gradual development. At present, there are mainly olfactory method and gas chromatography-mass spectrometry method. The olfactory method is subjective, and...
