Polyesteriverkko

Polyesteriverkko, or polyester mesh, is a fabric-like material made from polyester fibers arranged in a regular lattice. It is produced by weaving, knitting, or warp-knitting polyester yarns into a grid with evenly spaced openings. The term covers a range of products, from fine filtration screens to coarse reinforcement nets, and it describes both woven and knitted structures.

Properties of polyesteriverkko include high tensile strength and good abrasion resistance, which contribute to durability in demanding applications. The material typically remains dimensionally stable and exhibits relatively low elongation under load. Polyester is resistant to many chemicals and has moderate heat resistance, though performance depends on the specific polymer grade and any additives or finishes. UV stabilizers are commonly used to enhance outdoor service life. The openness of the mesh can be tailored during manufacture, affecting flow, filtration, and drainage characteristics.

Common applications span several sectors. In filtration and screening, polyesteriverkko serves as sieves, filters, or support screens for liquids and gases. In construction and civil engineering, it is used as reinforcement or separation layers, as well as in plaster and concrete curing mats. In agriculture and horticulture, shade nets and insect screens are made from polyester mesh. It is also used in packaging nets, textiles, and craft or industrial reinforcements. Recyclability varies by formulation and end-of-life processing.

Environmental considerations include non-biodegradability and the potential for microplastic release if fibers shed. Proper handling, finishing, and recycling options should be considered in lifecycle planning.
