PET monofilament yarn

PET is a common polyester material that is widely used in textile and industrial applications. PET monofilament yarn has good mechanical properties and cost-effectiveness, so it is widely used in many industries.

Main features

• High strength: PET yarn has excellent tensile strength and can withstand large mechanical stress.
• Heat resistance: PET yarn has high heat resistance and can usually withstand temperatures above 150°C, suitable for high temperature environments.
• Chemical resistance: PET yarn can resist corrosion from a variety of chemicals, especially in acidic environments.
• Good UV resistance: It can resist UV rays well and is suitable for outdoor applications.
• Low hygroscopicity: PET yarn has low water absorption, so its performance remains stable in humid environments and is not easily affected by moisture.

Application areas

• Textiles: Widely used in the manufacture of clothing, home textiles, etc. because of its durability and high color fastness.
• Industrial applications: such as conveyor belts, filter materials, reinforced composite materials, etc.
• Packaging materials: PET is widely used in the packaging industry, including the manufacture of bottles, films and various packaging bags.
• Others: It is also used for special purposes such as fishing nets, tire cords, sewing threads, etc.

Advantages

• Relatively low cost, with good cost performance.
• Excellent mechanical properties, suitable for various applications with high mechanical requirements.
• Stable chemical properties, suitable for various complex chemical environments.

Disadvantages

• Compared with TPEE, it has poor flexibility and is easy to break.
• Poor resilience, not suitable for applications with high elasticity requirements.

TPEE monofilament yarn

TPEE is a thermoplastic elastomer that has the characteristics of both rubber and plastic, so TPEE monofilament yarn has the dual advantages of elasticity and high strength.

Main characteristics

• High elasticity: TPEE has the same elasticity as rubber, can be stretched to several times its original length, and has excellent resilience.
• Fatigue resistance: TPEE yarn has excellent fatigue resistance and is suitable for applications that require repeated bending and stretching.
• Low temperature resistance: Unlike PET, TPEE maintains good performance at low temperatures and does not become brittle.
• Chemical resistance: Although not as chemically stable as PET, TPEE still has a certain tolerance to oils, solvents and a variety of chemicals.
• Good processability: TPEE yarn can be melted and formed at high temperatures, and has good processability.
• Comfort and softness: TPEE yarn is softer and feels better than PET, so it is widely used in clothing and home textiles.

Application areas

• Sporting goods: TPEE's high elasticity and fatigue resistance make it suitable for the manufacture of elastic fabrics, shoelaces, elastic bands, etc.
• Automotive industry: Due to its fatigue resistance and tensile resistance, TPEE is often used to manufacture automotive interior parts such as seats and seals.
• Electronic products: TPEE's softness and elasticity make it an ideal material for wire and cable coating.
• Medical devices: TPEE is also widely used in medical devices that require flexibility and high strength.

Advantages

• Excellent elasticity and resilience, suitable for scenes that require repeated stretching and bending.
• Good low temperature resistance, suitable for cold environments.
• Good softness and touch, suitable for close-fitting products.

Disadvantages

• High cost, complex production process.
• Chemical resistance and heat resistance are slightly lower than PET, and the applicable environment range is limited.
