OUTLINE
Summer training at RELIANCE INDUSRIES LIMITED,
Manufacturing division, ALLAHABAD
An amazing experience as I got to see, how exa
manufacturing of yarn take place.
Main objective was to learn what is the process o
manufacturing.

POLYMERIZATION
To form polyester, dimethyl terephthalate is first reacted witglycol in the presence of a catalyst at a temperature of 150
The resulting chemical, a monomer alcohol, is combined wterephthalic acid and raised to a temperature of 280C. Nepolyester, which is clear and molten is extruded through a sllong ribbon.

DRYING
After the polyester emerges from polymerization, the longribbons are allowed to cool until they become brittle.
The material is cut into tiny chips and completely dried to irregularities in consistency.

SPINNING
polymer chips are melted at 2
form a syrup like solution. Theput in a metal container calspinneret and forced througholes.
ring yarn is finer than open e
it has more hairiness as copen end.

DRAW THE FIBRE
when polyester emerges from the spinneret, it is soft and eelongated up to five times its original length.
This increases the strength and resilience of the fibre.
The fibre becomes solid and strong instead of brittle.
Drawn fibre may vary greatly in diameter and length, also tbe textured or twisted to create softer or duller fabrics.

WINDING
After the polyester yarn is drawn, it is
wound on large bobbins or flat-
wound packages, ready to bewoven into materials.
