Cotton Ring Spinning
The main activity of our company is the production of ring cotton yarns from mostly raw fibers, i.e. undyed. Spinning is marked by a series of stages that all take place within our factories in Val Seriana, according to the Made in Italy tradition.
Find out how we transform raw materials into yarns, such as natural fibers (cotton, linen, wool, angora, cashmere, silk, hemp, camel, yak, and more) and how we combine them with artificial and / or synthetic fibers to obtain blends.
Preparation of the raw material: opening and cleaning
The raw material arrives in our factories stored in bales and must be prepared for processing. It is therefore fluffed and cleaned, in such a way as to guarantee the uniformity, strength and regularity of the yarn. This preparatory phase is followed by carding.
Carding
The flaked and clean fibers feed the carding machine, which has the task of aligning them, discarding too short fibers, neps and impurities. A soft and light “carded” ribbon is formed at the machine exit.
Coupling and stretching
At this point, 6 to 8 carded belts are coupled and drawn to further mix and parallelize the fibers. The machine used is the “Drawing frame”, where several steps of the spinning process take place.
Combing of cotton
To obtain a high-end cotton yarn in terms of regularity, cleanness and resistance, combing is a fundamental activity, carried out by the “Comber”. The machine frees the drawn ribbon from residual impurities, eliminating the shorter fibers and making the ribbon even softer and shinier.
Spinning: from the preparation to the ring
On the spindle machine, we stretch and twist the ribbons previously prepared to transform them into slivers. In this way, we prepare the main spool and refine the fibers giving them the appropriate consistency to withstand the stress of the spinning process. Then the ring spinning comes into play, determining the count and the twist of the yarn, and wrapping it on the spindles.
Unlike open end spinning, ring spinning is longer and more complex. However, it allows production of top-quality yarns that are stronger, cleaner, and more versatile.
Spooling
After spinning, we gather the yarn unwound from several spindles into a single cone. During winding with yarn clearers, any defects of the yarn are also eliminated. The resulting cone is the packaging with which we present our staple fiber yarns on the market.
Twisting, doubling, singeing and dyeing
Finally, to obtain yarns with particular features, we carry out complementary processes, such as doubling, twisting and, if required, singeing. Our twisting capacity allows us to combine even multiple yarn ends, also with different features, thus achieving the creation of a limitless range of combinations.
