What is yarn?

Is a Pproduct derived from the combination of textile fibers which, subjected to spinning operations, have been transformed to obtain a continuous, long and flexible body: the yarn.
Spinning operations such as twisting are essential for joining fibers and textiles and obtaining the yarn suitable for weaving for the production of fabrics, knitwear, lace, etc. and for all other applications that require characteristics of resistance and elasticity to form a weave. The thickness of the yarns is indicated by the title .

In the textile industry there are two types of yarns: those formed by fibers of limited length, joined together by spinning operations (cotton, wool, linen and hemp yarns), and yarns obtained by twisting continuous threads together (eg. silk). Among those destined for weaving we can distinguish chain yarns, characterized by their consistency due to considerable twisting, and weft yarns which, on the contrary, are slightly twisted.
There are several types of yarn:
Spooled yarn, yarn wound on spools. Carded yarn, short-fiber yarn obtained in carding. Cordonato yarn, a yarn made up of several strands twisted individually and subsequently each other. Chain yarn, weft, yarn used for the chain, weft. Gassed yarn, simple or twisted or braided wind, which has undergone carbonation to remove the fluff. Raw yarn, natural color yarn not subjected to dyeing. Mélange yarn, a yarn composed of several different colored threads, or a mixture of differently colored fibers. Mercerized yarn, yarn immersed in a bath of caustic soda so that it acquires a shiny appearance. Mouliné yarn, a yarn consisting of several simple threads slightly twisted together. Reinforced yarn, a simple yarn that has undergone an additional twist to acquire a resistance almost equal to that of the twisted yarn. Twisted yarn, yarn composed of several simple threads that have undergone a strong twist after being joined together (different from the common yarn which is normally single). Mixed yarn, consisting of several fibers or yarns of different origins: silk and wool, terital and cotton, silk and lamé, etc. Sfumato yarn, dyed yarn whose colors are subsequently partially attenuated. Dyed yarn, yarn passed to the dyeing plant at the initial stage of processing (fiber dyed or tops), or in blends, or before or after combing, or in skeins.
The Silk Yarns are obtained by coupling the burrs of the cocoons in order to constitute a more or less considerable number of threads; after this operation, twisting is carried out according to the torque imparted.
