spinning

A method of drawing out and twisting together fibers to make a continuous thread or yarn. Spinning also refers to the manufacture of man-rnade fibers as they are formed by fcucing the material from which they are rnade through a spinneret. In conventional spinning, the tighter the twist, the stronger the yarn, but too tight a twist can weaken the final yarn. Crepe yarns have such an extremely high twist that the yarn actually turns back on itself (kinks), producing the characteristic crepe or corksc_rew look. Pabrics can be given shadow effects by the Lise of two yarns which have been twisted in opposite directions during spinning. This will strike each of these yarns in a different way producing this effect. See spinneret.
