![]() ![]() According to a study reviewing the evidence of wool as an allergen conducted by Acta Dermato-Venereologica, contemporary superfine or ultrafine Merino wool with their reduced fibre diameters do not provoke itch, are well tolerated and in fact benefit eczema management. ![]() In fact, contrary to popular belief, wool allergies are practically unknown. These reactions are likely a sensitivity to thicker and coarser fiber diameter or fiber ends. Some types of protein yarns (i.e., hair, silk, feathers) may feel irritating to some people, causing sensations of contact dermatitis, hives, wheezing reactions. In general, natural fibers tend to require more careful handling than synthetics because they can shrink, felt, stain, shed, fade, stretch, wrinkle, or be eaten by moths more readily, unless special treatments such as mercerization or superwashing are performed to strengthen, fix color, or otherwise enhance the fiber's own properties. Comparison of material properties Ī fully restored Derby Doubler, winding a sliver lap ready for finisher carding at Quarry Bank Mill in the UK. The resulting yarn can be used in knitted or crocheted items. It can also be made at home out of used clothing. It is often made from the remainder fabric of clothing manufacture, and therefore is considered a recycled and green product. T-shirt yarn is a yarn made from the same fabric as is used in T-shirts and other wearables. Cut-length only applies to staple fiber.įilament extrusion is sometimes referred to as "spinning" but most people equate spinning with spun yarn production. Denier and Dtex are the most common weight to length measures. Synthetic fiber is most often measured in a weight per linear measurement basis, along with cut length. Filament is a continuous strand consisting of anything from 1 filament to many. Tow is a continuous "rope" of fibers consisting of many filaments loosely joined side-to-side. Staple is cut fibers, generally sold in lengths up to 120 mm. Synthetic fibers come in three basic forms: staple, tow, and filament. These strands are drawn (stretched), annealed (hardened), and cured to obtain properties desirable for later processing. Synthetic fibers are generally extruded in continuous strands of gel-state materials. ![]() ![]() Some examples of synthetic fibers that are used as yarn are nylon, acrylic fiber, rayon, and polyester. Yarn can be made from a number of natural or synthetic fibers, or a blend of natural and synthetic fibers. Cotton, wool, and silk were the first materials for yarn, and textile trade contributed immensely to the ancient global economy. The human production of yarn is known to have existed since the Stone Age and earlier prehistory, with ancient fiber materials developing from animal hides, to reeds, to early fabrics. One of the things we like most about winter is the vast number of combinations that the cold offers us.The word yarn comes from Middle English, from the Old English gearn, akin to Old High German garn, "yarn," Dutch "garen," Italian chordē, "string," and Sanskrit hira, "band."
