TPEE Monofilament Yarn: Performance and Application

Since its establishment in 1989, Monofee New Materials Co., Ltd. has focused on the manufacture and development of monofilament yarns, of which TPEE monofilament yarns are one of our star products. TPEE, the full name of thermoplastic polyester elastomer, is a high-performance engineering material that combines the elasticity of rubber with the strength of engineering plastics.

Main characteristics

Excellent heat resistance: TPEE can maintain stable physical properties at extreme temperatures. Its operating temperature range is from -70℃ to 200℃, which is particularly suitable for applications in high temperature environments.
Excellent chemical resistance: TPEE has good resistance to most chemical media such as acids, alkalis, amines and diol compounds. The higher the hardness, the better the chemical resistance.
Outstanding mechanical properties: TPEE has high tensile strength and excellent fatigue resistance, which enables it to maintain performance under long-term cyclic loads.
Good processability: TPEE is easy to process and can be molded by thermoplastic processing such as extrusion and injection molding.

Monofee's Commitment

As a leading global monofilament yarn manufacturer, Monofee is committed to providing customers with high-quality TPEE monofilament yarn. Our products ensure product consistency and reliability through precise process control and continuous technological innovation. Our TPEE monofilament yarn not only meets the market demand for high-performance materials, but also promotes technological progress in related industries.

What are the key technologies in the production process of TPEE monofilament yarn

The production process of TPEE monofilament yarn involves a series of key technologies that ensure the quality, performance and application range of the yarn. The following are some core technologies in the production of TPEE monofilament yarn:

Polymerization process: The production of TPEE begins with the polymerization reaction of terephthalic acid (PTA) or dimethyl terephthalate (DMT) and 1,4-butanediol (BDO). This step is the basis of the manufacturing process and requires precise control of reaction conditions to ensure the molecular weight and distribution of the polymer.
Melt spinning technology: In the production of TPEE monofilament yarn, melt spinning is a common method. This process involves melting the polymer and extruding it through a spinneret to form filaments, which are then cooled and solidified to form monofilaments.
Drying: Since TPEE has a certain degree of hygroscopicity, the raw materials need to be dried before production to ensure that the water content is less than 0.1% to prevent material degradation and performance degradation.
Temperature control: Temperature control is crucial during extrusion and spinning. TPEE is very sensitive to temperature, so the temperature of the material pipe and screw needs to be precisely controlled to ensure the fluidity and stability of the melt.
Screw design: The design of the screw is crucial to the extrusion process of TPEE. The commonly used screw design should avoid excessive friction and overheating to prevent material decomposition. The aspect ratio and compression ratio of the screw need to be carefully designed.
Die design: The design of the die should avoid dead corners to ensure smooth flow of the material and convenient cleaning. For the production of pipes or special-shaped products, a long die is required to reduce shear stress and maintain a stable extrusion volume.
Cooling and shaping: The cooling trough equipment of TPEE is usually longer than that of general thermoplastics to ensure that the product can be cooled evenly and reach the desired shape and size.
Recycled material processing: The production process of TPEE may produce recycled materials. These materials can be mixed with new materials, but the proportion needs to be controlled and ensured to be dried again.
Selection of additives: In the production of TPEE, it is very important to select suitable additives, especially when acidic media are present. Acidic additives need to be avoided because TPEE may degrade at high temperatures.
Modification technology: In order to improve the performance of TPEE or meet specific application requirements, modification technology may be used, such as adding specific fillers, fibers or other polymers for blending modification.
