How a 100% Technical Textile Yarn is made.



Dried polymer chips fed into a melt spinning machines. The molten polymer is filtered before entering the spinneret (a wheel or plate with many tiny holes) to form yarn of different linear density as per specifications. Fibres of different length and thickness are made by using holes of different diameters and drawing them out at different speeds. The filaments are coated with water & oil to ensure dimensional stability, then they are air quenched and solidified, offering outstanding tensile strength and low shrinkage under heated conditions, as well as high elasticity. The yarn thus formed is further stretched 3-4 times its original length so its macro molecules lie parallel to the length of the fibre, and this offers full strength.
