Beilun News Network reporter learned from the inspection and quarantine department that "seven series of textile fiber identification methods" (SN/T 1901-2007) has been formally implemented since December last year, which marks the Lysell fiber, chitin fiber, The production and identification of seven new fibers, such as polylactic acid fibers, will be based on standards. 
In recent years, with the development of textile technology, some new types of fiber materials are emerging at an unprecedented speed, such as Lyocell fiber, chitin fiber, milk protein composite fiber, bamboo pulp fiber, and so on. Not only people are unheard of, but even some in the industry. People may not be able to make very accurate explanations. As the formulation of relevant standards failed to follow up in time, there were certain loopholes and difficulties in the production and identification of some new types of fibers.
In view of this situation, the inspection and quarantine system and related universities have co-authored the industry standard "Seven types of identification methods for textile fibers." The standard comprehensively uses combustion, microscope observation, chemical dissolution, coloring test, melting point determination, infrared absorption spectrum, and other test methods, and introduces the latest detection methods such as the extraordinary element color reaction to establish a set of experimental instruments and reagents operating procedures. , It has made scientific and effective physical and chemical properties of seven new types of fibers such as Lyocell fiber, bamboo pulp fiber, chitin fiber, soybean protein composite fiber, milk protein composite fiber, polylactic acid fiber, and polytrimethylene terephthalate fiber. Judgments were made and specific schemes for identifying these seven new fibers were developed.
The formulation and implementation of this standard will allow standards for the identification and identification of the seven new types of fibers that are currently in use to be used, which has changed the situation in which related work was relatively arbitrary. The inspection and quarantine authorities reminded relevant companies to learn new standards in a timely manner and carry out procurement, production and quality inspections in accordance with the requirements of the new standards.
