As we all know, the production functions of polyester products are more abundant and the types are gradually diversified. As high-end polyester products, they occupy an important position in the current market. In the production process of a series of textiles, the reliable quality polyester colored POY is Have undertaken important responsibilities. And because of its high-end positioning and the comparison of its product quality with raw materials, users are required to master a reasonable method to identify the quality of this polyester colored POY product itself.

1. Formic acid treatment

The method of realizing formic acid treatment under relatively stable conditions is a common way of identification. In the process of product purchase, high-quality polyester colored POY can be sampled and processed by formic acid washing treatment within the specified time. break down. After many washings, the insoluble fiber can be removed, and the remaining fiber can be dried and cooled. Considering its own quality, it can be confirmed that the quality of the polyester colored POY contained in itself is higher than other products. This reliable polyester colored POYpolyester POY Yarns manufacturers is made of reliable quality.

2. Near infrared spectroscopy

Fully collect the corresponding samples and realize the detection of the debilitating full response spectrum, and the quantitative analysis module through multiplication can effectively realize the predictive analysis of the sample of this theoretical colored product. Applying reliable quality polyester colored POY to an imported external spectrometer can observe and identify its own diameter and quantity. In this way, the percentage contained in the fiber can be effectively detected, so that the quality of the polyester colored POY itself can be compared and corresponding The composition analysis is more reliable.

All in all, many methods can distinguish the actual situation of the polyester colored POY itself. More importantly, it is to purchase through the polyester colored POY service with good reputation. Due to the high-quality research and development capabilities and better market, it can be positive Improve the technology to ensure that the production of real materials will implement the corresponding technical effects.
