Changling Test Technology National Patent

Recently, Shaanxi Changling Textile Technology Co., Ltd. has independently developed "a device for dynamic tension measurement of chemical filament tension under heating conditions", which has been authorized by the state. The utility model patent has broken through the key technology of important parts, dynamically measured the stress changes of chemical fiber filament, and comprehensively predicted the dyeing performance of later stage, and made the quality control of chemical fiber industry. Process improvement It is of great significance.

Changling textile and electric company has long tackled a device for dynamically measuring the tension of chemical filament yarns under heating conditions. It has broken through the key technologies of important components, and has carried out in-depth studies on pre tension control, force measuring device, electric heating device, main control mode, draft roller control model, and computer data processing. Research and Practice And achieved certain results.

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.
