Spinning Lab

The Rieter Short Staple Yarn Laboratory is designed to help meet the needs of the textile industry in applied research. State-of-the-art machinery converts fibers less than 65 mm into spun yarn. Spinning capability includes ring, compact, open-end and air-jet spinning. Services range from evaluating the processability of various fibers and blends to running trials for the determination of optimum machine settings and speeds.

Frequently Asked Questions…

In short, ring spun yarns are composed of short staple fibers that are held together by twists. All of the fibers are aligned parallel to each other in the long direction of the yarn (this is achieved through either the combing or carding process).

Ring spun yarns are used in most apparel and can also be used in upholstery and drapery.

Open ended spinning creates a yarn composed of fibers held together by twist or wrapper fibers. The yarns produced through open ended spinning contain fibers that are not as well aligned compared to that of ring spun yarns. However, open ending spinning is an efficient process for producing ticker yarns with a more uniform diameter.

Open ended spun yarns are most commonly used to produce denim, sweatshirts, terry cloth, t-shirts, and bedding.

Air-jet spun yarns are composed of a straight core of fibers, wrapped together with twisted fibers on the surface. Some properties of the yarn include more uniformity and less fuzz compared to that of ring spun. In contrast, air-jet yarns are not as strong as ring spun.

Air-jet spun yarns are commonly used to produce textiles used for sheets or pillow cases.
