Performance Characteristics Of Aramid Sewing Thread

Aramid sewing thread is one of the textile thread products produced in the textile industry. Its toughness is relatively strong, and it does not have a significant impact on its surface when used in harsh environments. Therefore, when producing products with high quality requirements, aramid sewing thread may be used. Next, let me take you to understand the characteristics of aramid sewing thread.
1. High strength: The characteristic strength can reach over 20.0CN/dtex, which is five times that of steel and more than twice that of general organic fiber materials;
2. Low density: Compared to steel, it is much lower, only 1/5 of the density of steel;
3. Good heat resistance: Under environmental conditions of 130 ℃, the strength is basically not lost, and it can be used normally at 200 ℃. Carbonization only occurs at around 427 ℃, and decomposition occurs above 500 ℃ without melting point;
4. UV stability: Long term exposure to UV light can cause mechanical performance loss, depending on wavelength, exposure time, radiation intensity, and product geometry.
Aramid sewing thread has high strength, low density, heat resistance, and UV stability that other textile threads cannot achieve. For example, gloves are made using Aramid sewing thread. The manufacturing process of aramid sewing thread is very complex, and the proportion requirements for raw materials are relatively strict. The personnel producing aramid sewing thread also need to have sufficient technical conditions. The good performance and high production requirements of aramid sewing thread are the main factors that cause the price of aramid sewing thread to be higher than that of ordinary yarn.
