Polyester is a very tough fibre.
While spinning the polyester yarn, the denier of the yarn is
adjusted in the hot stretching zone. During the hot-stretching
process some internal tension develops in the yarn. This tension
affects the natural feel of the yarn and thus affects the final
feel of the finished fabric.
To remove this internal tension in the yarn, a new polymer SWELLO-SK
has been developed. This product is very useful to open difficult
punches in the Roto yarn Polyester and Blended Fabrics and also
gives full relaxation to the fabric.
