Problems solved by technology

At present, the qualitative identification of Xyx fiber is still in the primary research stage. At the same time, due to its stable chemical properties, no suitable solvent for dissolving the fiber has been developed in the prior art, which has also resulted in the development of qualitative and quantitative analysis of Xyx fiber.
Its qualitative analysis has not yet been included in the relevant standards, and there is no report on the quantitative analysis method for the blending ratio of Yikesi fiber and other fibers in the prior art

Abstract

A method for quantitative chemical analysis of a two-component blended fiber product of Ix and cotton, characterized in that it sequentially comprises the following steps: 1. wetting the sample with a sulfuric acid solution; 2. placing it in a 30-80 ℃ water bath for heating; 3. taking the residual Filter the fibers by suction in the sand core crucible, and then rinse the sand core crucible with a small amount of sulfuric acid solution; ④ Take the residual fibers, add dilute ammonia water to neutralize them; Sand core crucible; ⑥ drying and cooling to obtain the final residual fiber. Using sulfuric acid dissolution method to complete quantitative analysis, the operation is simple, the test stability is strong, the harm to the environment and the human body is small, the test results are well balanced and the error is small.

Description

technical field [0001] The invention relates to a quantitative chemical analysis method for a blended fiber product, in particular to a quantitative chemical analysis method for a two-component blended fiber product of ike silk fiber and cotton fiber, and belongs to the technical field of textile inspection and detection. Background technique [0002] EKS fiber (EKS fiber, polyacrylate fiber) is a breathing fiber that can change with the external environment and the wearing space and is comfortable to wear, launched by Japan Toyobo Co., Ltd. Its fiber product is a new material that generates heat by itself and warms the body. The fiber not only far exceeds natural fibers in terms of hygroscopicity, but also has multiple functions such as moisture absorption, heat generation, pH control, flame retardancy, anti-pilling and anti-static, and has been widely used in clothing, home textiles and industrial fields. EKS fiber has a stable structure and very good chemical stability, ...
