Kierrätyskuidun

Kierrätyskuidun is a term used to refer to recycled fiber material derived from textile waste and reprocessed into new fibers or yarns for use in textiles and related products. It can be produced from post-consumer waste, such as used clothing and household textiles, or post-industrial waste, like factory scraps. Recycling can follow mechanical routes, which physically break down fibers and re-spin them, often resulting in shorter fiber lengths and the need for blending with virgin material to restore strength, or chemical routes, which depolymerize polymers to create new polymers that can be spun into fresh fibers.

Processing typically involves sorting, cleaning, shredding, and, depending on the fiber type and recycling method, chemical treatment. The choice of process is influenced by fiber type and color; natural fibers such as cotton or wool and synthetic fibers such as polyester or nylon can be recycled, though the methods and resulting fiber quality vary. Recycled fibers are commonly blended with virgin fibers to achieve desired properties like strength, durability, and appearance.

Applications of kierrätyskuidun include apparel, home textiles, insulation materials, nonwoven fabrics, carpets, and geotextiles. The environmental rationale rests on reducing textile waste and decreasing reliance on virgin resources, although energy use, chemical solvents (in some recycling methods), and fiber degradation can affect overall benefits. Availability and quality depend on effective collection, contamination control, and market demand, as well as the maturity of recycling infrastructure and pricing for virgin fibers.

Kierrätyskuidun is a key component of the circular economy in the textile sector, contributing to extended product lifetimes and closed material loops.
