Long staple spinning
In long staple spinning, fiber lengths of over 60mm are processed. Long
fiber and particularly fine woollen fibers are sensitive and can be damaged
and shortened by improper handling. In carding, special attention must thus
be paid to gentle fibers handling to maintain fiber length.
Carding machines with 2-4 main cylinders are used. The cylinders work in
conjunction with worker and stripper rollers for good mixing and carding of
fibrous raw material. SiroLock® worker and doffer wires were originally
developed for long staple spinning to protect fibers during carding and
maintain fiber length.
Long staple spinning encompasses woollen yarn, worsted and semi
worsted spinning. Wool is the most commonly used raw material, and long
synthetic fiber, cashmere and other natural fibers are also employed.
Metallic card clothing and flexible card clothing are also used.
