| | POLYESTER MANUFACTURING PROCESS |
 | | After the drawing is complete, each filament has the required denier, and has all its sub microscopic chains aligned parallel to the fibre axis, thereby improving the crystallinity of the fibre structure and imparting certain strength. |
 | | DENIER: Usually the actual denier is a little on the finer side i.e for 1.2 D, it will be 1.16 and for 1.4, it could be 1.35. |
 | | In conclusion it must be stated that though the amount of spin finish on the fibre is only in the range 0.105 to 0.160, it decides the fate of the fibre as the runnability of the fibre is controlled by spin finish, so it is the most important component of the fibre. |
