Wuxi Jintong High Performance Fibre Co., ltd

WUXI JINTONG HIGH PERFORMANCE FIBRE CO., LTD was founded in 1994, after a decade of study and research, we’ve been dedicating to improvement of production in the field of industrial polyester(PET) monofilament since 2005, it requires a higher standard for physical properties,process stability and conformity of production. Through protracted and unremitting efforts, we have successfully achieved major breakthrough in fine-denier yarn technical difficulties in production and became the first well-accredited domestic enterprise that is qualified to make mass production of high-end PET yarn for screen printing mesh. As the industry pioneer and leading enterprise, with constant effort and competitive price-performance, Jintong has promoted the rapid development of domestic screen printing weaving enterprises.

In the past five years, JINTONG has continuously developed new products and new applications in downstream industries, actively expand domestic and overseas markets while maintaining the competitive advantage of fine denier PET monofilament. Our self-developed BIODEGRADABLE PLA monofilament can be applied to the GREEN FOOD packaging. Newly launched products :PBT/PA6 skin-core conjugated monofilament for sport footwear and clothing, cool-feeling polyethylene (PE) yarns for high-end customized home textile have achieved satisfactory growth. JINTONG has acted proactively and with an innovative approach, we work closely and exchange ideas with customers to satisfy most needs.

We have put emphasis on R&D and innovation, JINTONG as drafting committee, was entitled to formulate four industrial standards of monofilament, including 《PET MONOFILAMENT》《PA66 MONOFILAMENT》《PLA MONOFILAMENT》《LMPET/PET COMPOSITE MOFONILAMENT》; and participated in drafting two industrial standards, including《PP MONOFILAMENT》《HIGH SHRINKAGE PET》. Many years of experience help us to gain technical superiority in the field of monofilament of synthetic fibre, we have mastered multi-core-technologies in the production and processing of high-molecular polymer fibre.

Industry knowledge

What are the mechanical properties of PPS monofilament? 

PPS (Polyphenylene Sulfide) monofilament is a type of fiber that is known for its excellent mechanical properties. Below are some of the key mechanical properties of PPS monofilament.
1. Strength: PPS monofilament has high tensile strength, which means it can withstand high amounts of pulling or stretching force without breaking. The strength of PPS monofilament can range from 1.5 to 3.5 grams per denier (gpd), depending on the specific grade and processing conditions.
2. Stiffness: PPS monofilament possesses high stiffness, which refers to its resistance to bending or deflection under load. This property makes it suitable for applications where rigidity is required.
3. Flexibility: Although PPS monofilament is stiff, it still exhibits reasonable flexibility. This allows the fiber to be bent or twisted without permanently deforming or breaking, making it useful for applications such as braiding or weaving.
4. Fatigue resistance: PPS monofilament has good fatigue resistance, meaning it can withstand repeated cyclic loading without failure. This property is particularly important in applications where the material is subjected to dynamic or repetitive loading, as it helps to prevent premature failure or degradation of the fiber.
5. Creep resistance: Creep refers to the tendency of a material to deform slowly and irreversibly under constant stress over time. PPS monofilament exhibits a low creep rate, which makes it suitable for applications requiring long-term dimensional stability and resistance to creep, such as in the textile industry.
6. Thermal stability: PPS monofilament has excellent thermal stability, allowing it to maintain its mechanical properties at elevated temperatures. The melting point of PPS monofilament can range from 280 to 300°C, making it suitable for high-temperature applications.
7. Chemical resistance: PPS monofilament exhibits excellent chemical resistance to a wide range of solvents, acids, and alkalis. It is resistant to most organic solvents, oils, and fuels, as well as many inorganic chemicals. This property makes it suitable for applications where chemical exposure is a concern.
8. Dimensional stability: PPS monofilament has high dimensional stability, meaning it retains its shape and dimensions even under varying environmental conditions, such as temperature and humidity changes. This is important in applications where precise sizing and dimensional control are required.
PPS monofilament exhibits high strength, stiffness, flexibility, fatigue resistance, creep resistance, thermal stability, chemical resistance, and dimensional stability. These properties make it suitable for a wide range of applications, including filtration, textile reinforcement, aerospace, automotive, electrical insulation, and many others.

Can PPS monofilament be used in high-temperature environments? 

PPS (polyphenylene sulfide) is a high-performance thermoplastic that offers excellent chemical resistance, high thermal stability, and good mechanical properties. These characteristics make PPS suitable for various applications, including those involving high-temperature environments.
PPS generally has a continuous use temperature of around 200 to 220°C (392 to 428°F). However, it can also withstand short-term exposures to higher temperatures. Some grades of PPS, such as reinforced or modified PPS, can withstand temperatures up to 260°C (500°F) without losing their properties.
In high-temperature environments, PPS monofilament can be used for various applications, including industrial filtration, electrical insulation, and automotive parts. Its ability to resist deformation or degradation at elevated temperatures is particularly valuable in these applications.
One of the key advantages of PPS monofilament in high-temperature environments is its excellent dimensional stability. Unlike some other thermoplastics, PPS retains its shape and mechanical properties even at elevated temperatures. This stability makes it suitable for use in applications where dimensional accuracy is critical, such as automotive engine components or aerospace parts.
PPS monofilament also offers excellent chemical resistance, which allows it to withstand exposure to various chemicals, acids, and bases commonly encountered in industrial environments. This makes it suitable for filtration applications where resistance to chemical attack is necessary.
Moreover, PPS monofilament exhibits good resistance to creep, which is the tendency of a material to deform under long-term exposure to constant stress or load. This property is beneficial in high-temperature applications where materials may be subjected to prolonged stress. PPS monofilament can maintain its shape and mechanical properties under these conditions, ensuring long-term performance and reliability.
However, it is important to note that the performance of PPS monofilament can vary depending on the specific grade and formulation used. Different manufacturers may offer PPS with different temperature ranges and mechanical properties. Therefore, when selecting PPS monofilament for use in high-temperature environments, it is crucial to consult the manufacturer's data sheets and specifications to ensure that the material meets the desired requirements.
PPS monofilament can be used in high-temperature environments due to its excellent thermal stability, chemical resistance, dimensional stability, and resistance to creep. Its ability to retain its shape and mechanical properties at elevated temperatures makes it suitable for various industrial applications, where reliability and performance under challenging conditions are required.
