Nonwovens

The nonwovens industry uses roller cards to process staple fibers into nonwovens. The nonwovens fabrics manufactured are used in the traditional textile industry as well as in very different technical areas, from the automotive industry and geotextiles to the hygiene sector and medical industry.

Short Staple Spinning

"Well carded is half spun."

The revolving flat card is called the heart of the spinning mill. This illustrates the immense significance of carding to the end result and the quality of the yarn.

The concept of carding has existed since 1770, and revolving top cards since 1850. Basically, these cards contained similar elements that still can be found today on high production cards: licker-in, cylinder, revolving tops, stationary flats and doffer. Each element takes an important function in carding.

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.

Product services Carding

Not only wires are responsible for good carding performance, service also plays a major role. The distance between rollers must be correctly set and wires precisely mounted to the carding rollers in order to exhaust the full potential of the raw material.
