What Is The Method To Distinguish The Quality Of Polyester DTY Yarn?

　　With the improvement of modern people's living standards and the increasing market demand for high-grade clothing fabrics, polyester DTY yarn occupies an important position in the clothing industry. Because the production cost of polyester DTY yarn is much higher than that of ordinary clothing fabrics, this fabric is often used in some high-grade clothing. If you want to purchase clothing made of polyester DTY yarn with acceptable quality, you need to have an eye to identify the quality. Then, according to what method can we identify the quality status of the better polyester DTY yarn in the industry?

　　Methods: Chemical solution filtration weighing method

　　At present, most polyester dye yarns in the market contain polyester POY yarn, and the quality of polyester dyyarn can be identified by the content of colored POY in polyester. Therefore, when distinguishing the quality of polyester dyyarn, we can use formic acid or zinc chloride to wash the insoluble fiber, and then we can use a weighing instrument with high accuracy to accurately measure the specific weight of the fiber left after the reaction with the chemical solution. Generally, the polyester dyyarn with high polyester-colored POY content has high quality.

　　Methods: Microscopic projector observation projection imaging method.

　　Although polyester DTY yarn seems to have no obvious difference from ordinary silk thread in appearance, the raw materials and technological level used in the production of this kind of colored silk thread are more complicated than those of silk thread, and obvious differences can be found by observing it under a micro projector. Therefore, when consumers identify the quality of polyester DTY yarn, they can use the assistance of a micro-projector, which can record and compare the specific values of projection images to judge their quality.

　　The above content is an introduction to the method of distinguishing the quality of polyester dtyarn. These two methods mainly distinguish the quality of polyester DTY yarn with a good reputation from a professional point of view, but for ordinary consumers, the operability of these two methods is not too high. If ordinary consumers want to distinguish their quality, they can do so by observing their glossiness and brightness.
