plastfibre

Plastfibre is a generic term for fibers made from plastic polymers, produced for textiles and a range of other applications. The term covers a broad class of synthetic fibers created through processes such as melt-spinning or solution-spinning of thermoplastic polymers. The most common plastfibre types are polyester (polyethylene terephthalate, PET), nylon (polyamide), polypropylene (PP), and acrylic fibers. Production typically involves melting the polymer and forcing it through a spinneret to form continuous filaments, which are then drawn to increase molecular orientation and strength. These filaments can be used as filament yarns or cut into staple lengths for weaving, knitting, or nonwoven production.

Properties of plastfibre depend on the polymer but generally offer advantages such as high strength, durability, and chemical resistance. Polyester provides dimensional stability and moisture management; nylon is known for toughness and abrasion resistance; polypropylene is lightweight and resistant to chemicals; acrylic fibers offer warmth and softness. Plastfibre fabrics are used in clothing, upholstery, carpets, and industrial textiles, as well as in geotextiles, filtration media, and composite reinforcement.

Environmental considerations include non-biodegradability and the potential release of microplastics during washing. Recycling options include mechanical recycling into secondary fibers or chemical recycling back to monomers for new polymer production. Research continues into bio-based or biodegradable plastfibre variants, though widespread adoption depends on cost and performance considerations. The term plastfibre may be used differently in various regions, but it generally refers to fibers derived from plastic polymers rather than natural fibers.
