Embodiment 1

[0023] (1) Strong oxidant treatment of the cellulose fibers to be tested: use hydrogen peroxide as a strong oxidant, the treatment temperature is 90° C., the treatment time is 1 h, the hydrogen peroxide content is 5 g / L, and the bath ratio is 1:45.

[0024] (2) The treated fiber is made into a sample piece: ① Pulverize spectral-grade KBr in an agate mortar and grind it to a fine powder, dry it in a vacuum oven, and place it in a desiccator for use; ② Put the treated fiber Wash with water at 80°C until neutral, and dry in a vacuum oven for 16 hours to dryness; weigh 2 mg of fiber samples for drying, adjust the humidity for 24 hours, and grind to 2 μ; ③ Weigh 2 mg of fiber samples, and use 1 mg of samples to The ratio of 150mg KBr weighs dry KBr and pours it into an agate mortar and grinds it in a drying oven until the two are completely mixed; 13mm transparent sheet with a thickness of 0.8mm.

Abstract

The invention relates to a method for identifying bamboo fibers. The method comprises the steps of processing a sample to be tested by utilizing a strong oxidant which does not dissolve the cellulosic fiber, wherein the processing temperature is 70 to 95 DEG C, the processing time is 0.5 to 4 hours, and the bath ratio is 1: 20 to 1: 60, and obtaining a treated sample; making the treated sample into a test piece, testing the test piece in an infrared spectrometry, and identifying the bamboo fibers by virtue of an infrared spectrum of the sample. The method for identifying the bamboo fibers based on an important ingredient anthraquinone in the bamboo fibers is provided, and the method is sensitive and accurate.

Description

technical field [0001] The invention belongs to the identification field of cellulose fibers, in particular to a method for identifying bamboo fibers. Background technique [0002] Bamboo fiber is a new type of biomass fiber. Studies have shown that bamboo fiber and its products naturally have excellent properties that other cellulose fibers such as antibacterial and antibacterial do not have. According to different materials and processing techniques, bamboo fiber is divided into two types: bamboo fiber and bamboo pulp fiber. Bamboo fiber is a bast fiber obtained from bamboo stems, and is a kind of primary fiber directly extracted from bamboo poles. Bamboo pulp fiber is a regenerated cellulose fiber made by making bamboo into pulp and then spinning viscose fiber. Due to the large price difference between bamboo raw fiber, bamboo pulp fiber and ordinary viscose fiber, merchants are driven to label ordinary viscose fiber as bamboo fiber, shoddy. This has not only harmed c...
