Polyester monofilament yarn, as a synthetic fiber made of polyethylene terephthalate (PET), plays an important role in the textile and industrial fields with its excellent physical properties and chemical stability.

Characteristics of polyester monofilament yarn

• High strength: The high strength of polyester monofilament makes it excellent in stretching and load-bearing, making it an ideal choice for making high-strength fabrics or sturdy materials.
• Good wear resistance: Excellent wear resistance means that polyester monofilament is not easily worn even under frequent use or friction.
• Anti-bacteria and mildew: Polyester monofilament has antibacterial and anti-mildew properties, suitable for making mildew-proof and antibacterial products.
• High temperature resistance: Polyester monofilament can maintain stable physical properties under high temperature environment.
• Easy to dye: It has good affinity for dyes, is easy to dye, has high color fastness, and can achieve a variety of color options.

Production process

The main production processes of polyester monofilament include one-step method and two-step method.

• One-step method: Use a spinneret with 8, 10 or 12 holes to complete the spinning forming, primary fiber drafting orientation, fiber heat setting and winding processes on the same machine to directly obtain monofilaments.
• Two-step method: Use high-speed spinning and high-speed stretching and twisting technology to first obtain pre-oriented yarn (POY), and then stretch and twist, which is called secondary molding, to improve the physical and mechanical properties of the finished fiber.

Application field

• Industrial use: Mainly used for skeletons in industrial conveyor belts, weaving filter nets, rubber wire external sleeves, etc.
• Civil use: Mainly used for matching bags, straw hats, curtains, wedding dresses, clothing, etc. 30D polyester monofilament is a new product with high added value and high environmental performance. It is the basic raw material for the production of shoes, bags and stage costumes, and has a very broad market prospect.

Types

There are many types of polyester monofilaments, including flame-retardant monofilaments, triangular shaped monofilaments, flat monofilaments, high shrinkage monofilaments, hollow monofilaments, cationic monofilaments, full matte monofilaments, UV-resistant monofilaments, etc., to meet different application requirements.

Identification method

The burning characteristics are a way to identify polyester monofilaments. Polyester monofilaments soften, melt and curl when approaching flames, melt in the flames, burn slowly, have yellow flames, blue flame edges, and black smoke at the top of the flames. After leaving the flame, it may continue to burn or self-extinguish. It has a slightly aromatic or sweet smell when burning. The residual characteristics are hard and black beads, which are not easy to crush with fingers.
