How to ensure a tight bond between the core elastic yarn and the outer covering yarn in the production process of Covered Rubber Elastic Yarn?

In the production process of Covered Rubber Elastic Yarn, it is crucial to ensure a tight bond between the core elastic yarn and the outer covering yarn, which directly affects the elasticity and service life of the product. We carefully select high-quality elastic fibers as the core material. These elastic filaments not only have good elastic recovery rate, but also need to have certain strength and wear resistance to ensure that they are not easily broken or deformed during long-term use.
In the selection of outer covering yarn, we pay attention to the fineness, twist, and compatibility with other materials of the yarn. By optimizing the parameter design of the yarn, we can ensure that the coating layer can tightly and uniformly wrap around the surface of the elastic yarn, forming a stable composite structure.
In the production process, we use advanced wrapping techniques such as air wrapping or mechanical wrapping. These technologies can precisely control the thickness and uniformity of the coating layer, ensuring a tight bond between the core elastic yarn and the outer yarn. At the same time, we also regularly maintain and calibrate our production equipment to ensure the stability and consistency of the production process.
In addition to technical measures, we also focus on controlling the production environment. Maintaining suitable temperature and humidity, high air cleanliness, and other conditions in the production workshop can help reduce the interference of adverse factors in the production process and improve the quality stability of products.
