Superfine yarns
After linen and wool, cotton is the oldest textile fiber. Cotton is the most popular fabric in the world, economic, very versatile, it perfectly absorbs dyes. There are cottons of different qualities according to the origin.
Properties and Benefits of Superfine Yarns
The cottons are classified according to the count, while the length of the fiber determines the quality: the longer it is, the shinier, resistant and precious the cotton is. The length of the fiber can measure from less than 20 to more than 40 millimeters.
The most prized is the Sea Island, with a long silky fiber, which is used for the most refined garments. The Superfine St. Vincent reaches 50 and 60 millimeters. Egyptian cotton also called "Jumel" or "Moho" is characterized by shades of color ranging from yellow to brown. Peruvian cottons, Pima, as prized as Egyptian, have the appearance of wool so they are often used in a mixture with this fiber.
Superfine wools are wools with an average fiber diameter below 17 micron, fine wools are from 17 to 19, and above 19 are ordinary wools. A traditional but still very common method of indicating wool mean fiber diameter is the “Super S”: higher numbers indicate lower mean fiber diameter.
Superfine wool fibers are softer and smoother to the touch than coarser wool, but that is not all. At equal yarn count there are more superfine wool fiber in the cross section compared to normal wool, this makes the yarn stronger, softer and more even. With finer fibers it is possible to spin finer yarns, and with finer yarns it is possible to weave lighter fabrics, good for all seasons.
Machines & solutions for processing Superfine Yarns
Twisting
The Electronic Drive System allows to set via PC any working parameter, introducing an important flexibility element, allowing to reduce set up times. The thread guide electronic control allows to set winding angle, traverse stroke, position on the package tube and the yarn distribution over the package. All above improves design and formation of the package for dyeing process, optimizing all the downstream processes, thus allowing customers to obtain the best results.
Multicone Thread guide
The different downstream processes need a wide flexibility in the wound package construction, to optimize specific efficiencies. Cones for dyeing, warp, weft, knitting and twisting require completely different formation characteristics in terms of geometry, traverse stroke, shape of the edges and density. Savio Multicone electronic thread guide system is the solution to achieve flexibility in package formation.
