Problems solved by technology

EKS fiber has attracted more and more attention from people, but the current research on the performance and structure of EKS fiber is rarely involved. Therefore, it is necessary to conduct systematic qualitative research on it, which can allow us to fully understand its performance and characteristics. Understanding its structure can further expand its scope of use and develop its application fields. It is of great significance for the development of functional textiles to enrich product types, expand product differentiation, and meet people's needs for comfort, safety and environmental protection.

Embodiment 1

[0036] Such as figure 1 Shown, a kind of qualitative detection method of EKS fiber, comprises following sequential steps:

[0037] (1) Combustion detection: Burn the fiber with a flame, and identify the fiber according to the state of the fiber when it is close to the flame, when it is in contact with the flame, and when it leaves the flame, as well as the color during burning and the characteristics of the residue after burning. If the fiber does not melt or shrink when it is close to the flame , when it burns in the flame, it is slow burning and emits white smoke, and it is self-extinguishing when it leaves the flame, and the residue is a thin and soft black floc, then it may be judged to be EKS fiber, and proceed to the next step; otherwise, it is not EKS fiber , the detection ends;

[0038] (2) Microscopic examination:

[0039] Longitudinal slice preparation: Embed an appropriate amount of fiber in the groove of a Hastelloy slicer, cut a certain length of fiber and extra...

Embodiment 2

[0052] Such as figure 1 Shown, a kind of qualitative detection method of EKS fiber, comprises following sequential steps:

[0053] (1) Combustion detection: Burn the fiber with a flame, and identify the fiber according to the state of the fiber when it is close to the flame, when it is in contact with the flame, and when it leaves the flame, as well as the color during burning and the characteristics of the residue after burning. If the fiber does not melt or shrink when it is close to the flame , when it burns in the flame, it is slow burning and emits white smoke, and it is self-extinguishing when it leaves the flame, and the residue is a thin and soft black floc, then it may be judged to be EKS fiber, and proceed to the next step; otherwise, it is not EKS fiber , the detection ends;

Abstract

The invention relates to a qualitative detection method for EKS fibers, comprising the following steps orderly: (1) combustion detection, (2) microscope detection, (3) dissolution detection, (4) nitrogen-containing color reaction test, (5) chlorine-containing test, and (6) infrared spectroscopy detection. The method is an integrated method for detecting fibers. According to the invention, the microscope observation method, combustion method, infrared spectroscopy method, dissolution method and the like are used for integrated detection of fibers; the combustion method or microscopic method can be used for finding out a big class of the fibers at first, then other methods can be used for eliminating other fibers one by one, and finally the variety of the fibers can be determined. The detection method has the advantages of accuracy and rapidness, and can save test samples.

Description

technical field [0001] The invention relates to a qualitative detection method of EKS fibers. Background technique [0002] EKS (EKS) fiber is a new type of intelligent differential synthetic fiber of this type, which was launched by Japan Toyobo Co., Ltd. EKS fiber can change with the changes of the external environment and the wearing space, creating a comfortable breathing fiber for wearing. The concept of creating this fiber is "providing functional fibers that create a comfortable life for people". EKS fiber can not only regulate the temperature and humidity between the human body and clothing, but also protect the human body and the environment. Wearing EKS fiber products in the cold winter can make use of its sweat-absorbing and heat-absorbing functions to increase the temperature between the human body and clothing, making you feel warm and comfortable. It is the company's highly hydrophilic treatment of polyacrylic acid molecular chains, the introduction of -NH2 a...
