Changling Textile Electrothermal Long Filament Thermal Stress Testing Technology Won National Patent

The authorized patented technology mainly relates to a device for measuring the tensile strength of chemical fibers in chemical fiber industry under dynamic heating conditions. This kind of instrument comprehensively tracks and controls the quality of chemical fiber filament in the production process, instead of the traditional knitted socks dyeing method and static test of heat shrinkage. Through heating the filament, the yarn tension is measured regularly, and the internal stress changes are measured by dynamic stretching. Finally, the average value and coefficient of variation of tensile tension and various charts are obtained. The change of the force value really reflects the density of the internal molecular structure of the chemical fiber and predicts the dyeing property in the later stage. The patent technology understands the quality and improvement of chemical fiber enterprises. Production process And so on are of great significance.

It is reported that the patented technology has been successfully applied to the thermal stress testing instrument of HDT-1 chemical fiber filament produced by Changling spinning and weaving company, and has been widely used in textile enterprises all over the country.
