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 thread suitable for weaving for the production of fabrics, knitwear, lace, etc. and for all other applications that require resistance and elasticity characteristics 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 the operations of spinning cotton, wool, linen and hemp yarns, and yarns obtained by twisting continuous threads together, for example. silk. Among those destined for weaving there are chain yarns, characterized by the consistency due to considerable twist, and weft yarns which, on the contrary, are not very twisted.rti.
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 between them. Chain yarn, weft, yarn used for the chain, weft. Gassed yarn, simple breath, or twisted, or braided, which has undergone carbonation for the elimination of fluff. Raw yarn, natural color yarn not subjected to dyeing. Mélange yarn, a yarn composed of several different colored threads, or a mixture of different 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 unique. 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. Yarn Dyed, yarn passed in the dyeing plant at the initial moment of processing, dyed in fiber or in tops, or in blends, or before or after combing, or in skeins.sse. 
Silk yarns are obtained by coupling the burrs of the cocoons in order to form a more or less considerable number of threads; after this operation, twisting is carried out according to the torque imparted..
