By-Products of Wool

The use of waste is very important to the wool industry. Attention to this aspect of the business has a direct impact on profits.
These wastes are grouped into four classes:

Noils

These are the short fibers that are separated from the long wool in the combing process. Because of their excellent condition, they are equal in quality to virgin wool. They constitute one of the major sources of waste in the industry and are reused in high-quality products.
 

Soft Waste

This is also high-quality material that falls out during the spinning and carding stages of production. This material is usually reintroduced into the process from which it came.
 

Hard Waste

These wastes are generated by spinning, twisting, winding, and warping. This material requires much re-processing and is therefore considered to be of lesser value.

Finishing Waste

  • This category includes a wide variety of clippings, short ends, sample runs, and defects. Since this material is so varied, it requires a great deal of sorting and cleaning to retrieve that which is usable. Consequently, this material is the lowest grade of waste.
