The heat setting is a thermosetting process which brings dimensional stability, volumetric growth (bulkiness), softness, resistance to wrinkles and temperature to the yarn.This reprocessing of PET BCF Yarn to heat setting is called PET BCF Straight Heat Set yarn.

Production Process:

To produce Straight Heat set Yarn, the PET BCF yarn is twisted/cabled on cabling machine. Twisted/Cabled bobbins are taken on creel of heat set machine. It is coiled and laid on a belt and passed through a tunnel for a specified time. Specific temperature and steam is applied into the tunnel, so that the twist in the yarn gets fixed permanently and the yarn becomes Straight Heat Set. The yarn is winded on paper tubes and bobbins are produced with specific length and weight as per requirement of customer.
