Characteristics and production process of high strength polyester industrial silk!

high strength polyester industrial silk refers to high-strength, coarse denier polyester industrial filament, its density is generally not less than 550dtex. It has a variety of excellent characteristics, is widely used in many fields, the following is a detailed introduction about it:

Features:

High strength: This is the most prominent feature of high strength polyester industrial silk, its strength is much higher than ordinary polyester fiber. For example, in some application scenarios that need to withstand large tensile forces, such as conveyor belts, lifting belts, etc., high strength polyester industrial silk can provide reliable strength support.

Low elongation: The elongation rate is low when the force is applied, which makes it able to maintain good dimensional stability during use and is not easy to cause excessive deformation due to force.

High modulus: The modulus is a measure of the material's ability to resist deformation, and the high modulus of high-strength polyester industrial silk makes it have good rigidity and straightness.

Good heat resistance and chemical resistance: it can still maintain good performance under high temperature environment, and has a certain tolerance to acid, alkali and other chemical substances, suitable for some harsh working environments.

Production process:

Raw material preparation: Polyester chips are usually used as raw materials, and the quality and performance of polyester chips have an important impact on the final quality of high-strength polyester industrial silk. Before production, polyester chips need to be dried and other pretreatment to remove moisture and impurities.

Spinning process: Polyester slices are fused and extruded by screw extruder to form melt. After the melt is measured by the metering pump and filtered by the filtration system, it is ejected from the spinneret to form a filament bundle. The tow is then cured by side-blowing cooling.

Draft heat shaping: The cooled tow is drawn and heat shaping to improve the strength and dimensional stability of the tow. During the drafting process, parameters such as the drafting multiple and speed need to be controlled, and the temperature and time of heat setting need to be adjusted according to the specific process requirements.

Winding forming: the wire bundle after being shaped by draft heat is networked and then wound forming to obtain the finished product of high-strength polyester industrial silk.
