ESSAY: PLY YARN TWISTER
Ply Yarn Twister Machine is designed for pre-twisting the yarns/tapes for making the ply from Monofilament, Dan line, PP Tapes, Multifilament, Cotton and Jute yarns etc.
Yarn Twist:
In the manufacture of staple fibre yarns, twist is inserted into the fine strand of fibres to hold the fibres together and impart the desired properties to the twisted yarns. Without twist, the fine strand of fibres would be very weak and of little practical use. A change in the level of twist also changes many yarn properties, such as strength and softness.
Definition:
Twist may be defined as the spiral disposition of the components of a thread which is usually the result of relative rotation of the two ends. Twist is generally expressed as the number of turns per unit length of yarn, e.g. turns per inch (tpi), turns per meter (tpm), etc.
What exactly does twist to a yarn?
The twist in a yarn binds the fibres together and helps to keep them in the respective positions. It thus gives coherence to yarn.
Twist gives sufficient strength to the yarn.
Twist is also used to bring about novel effects that are prominently visible when the yarn is converted to fabric. This is achieved primarily by having a combination of yarns with different twist levels and twist directions in the fabric.
Twist Direction:
A twist can be either in Z direction or S direction as indicated in the following figure, depending on the orientation of the surface fibre in relation to yarn axis.
