A few days ago, the National Chemical Fiber Standardization Technology Commission (SAC / TC586) held the first standard review conference in the 2021 Chemical Fiber, the National Chemical Fiber Commission, a total of more than 130 people in the National Chemical Fiber Board, and the chemical fiber standardization expert. Participants considered three national standards such as "chemical fiber short fiber tensile properties" and "ultra high molecular weight polyethylene filament".

Important basic method standard revision

The short fiber tensile properties, short fiber curl performance, and filament tensile performance test methods were reviewed by this review method for more than 10 years, and the standard scope of standard applications, basics will be expanded through the revision of this standard. It covers new fiber products in recent years, and further optimizes the relevant test conditions based on the progress of test technology. "Synthetic fibrous double component composite filament elastic properties" provides a basis for the elastic performance test of the two-component composite filaments; the "chemical fiber single wire bending performance test method for the development of the filaments", It is an innovative method standard.

Develop borne polyester series product standards

And supporting method standards

In recent years, non-chasting catalysts have become one of the focus of the polyester industry, and the non-chalrons polyester series products are gradually maturing in technology and applications. The development of relevant standards further standardizes the technical indicators of non-chalrons polyester, which is conducive to further propeling the improvement, progress and implementation of polyester catalytic technology, which is of great significance for promoting the green sustainable development of my country's textile fiber industry.

Systematic revision product standard involving multiple chemical fiber industries

The concentrated chemical fiber product standards also relate to polyester, nylon, ultra-high molecular weight polyethylene fiber, polyethylene terephthalate (PBT), etc., standardization of related products, will standardize chemical fiber industry The further rich and improvement of the system and the sustainable development of functional differentiated products have a positive driving role.
