Abstract
A recycled fancy yarn includes at least two core strands forming a warp thread, and at least one ornamental strand that is twined, twisted or wound around the warp thread to form a weft thread. The core strand is formed by a single first monofilament or a single first filament bundle, and the ornamental strand is formed by a single second monofilament or a single second filament bundle. The first monofilament and/or second monofilament is made of an environmentally friendly material; or the recycled fancy yarn can be recycled or naturally decomposed in the environment, such that the quantity of produced wastes can be reduced, and environmental burden is hardly caused.
