The process for recycling wool is very similar to the process for recycling cotton (click here to review that process). Definition: Recycled Wool is a natural fiber reusing pre-consumer (post-industrial) or post-consumer wool waste. Pre-consumer waste comes from any excess material created during the steps of material and product manufacturing, e.g. selvage from weaving, fabric from factory cutting rooms, or excess production/unsold items that would normally be disposed of as waste. Post-consumer waste comes from household resources, e.g. used apparel or home textile products. Cutting room waste as well as post consumer waste are first separated by their color and quality, and then placed into stripping machines which breaks the fabric into pieces. Fibers are then pulled apart and the mixture is carded several times to clean and mixes the fibers before being re-spun into new yarns. Carding process allows the use of short fibers and different lengths in blends of the most variable composition1 and results in a yarn of a particular aspect and properties differing to commonly used worsted yarn.
