Grey Cotton Dropping Waste is a residual cotton byproduct obtained during the carding and combing processes in textile mills. This waste consists of shorter cotton fibers, slubs, seed particles, and dust that fall below the carding machine’s cleaning line. With a natural greyish tone and medium fiber length, it is ideal for use in open-end spinning and low-grade yarn production, as well as for manufacturing cleaning materials, padding, and other recycled textile applications.
Cotton Fan Fly Waste is a lightweight, fibrous byproduct collected from the filtration and exhaust systems (fans) of textile mills during the cotton processing stages. This waste consists of fine lint, microfibers, and dust-like cotton particles that are airborne during carding, combing, and spinning operations. Though soft and less structured, it is rich in cotton fiber content and is commonly used in recycled yarn production, low-grade spinning, and insulation materials.
