The feasibility and technical characteristic of modified Murata 33H draw-texturing machine in manufacturing thick and thin polyester filament were discussed.

The diameter of PU disk was changed from 6 mm to 9 mm, enabling to increase prcessing speed of DTY machine and reduce production cost.

The oil box with corresponding parts and exhaust pipe were fixed to the oil system of FK6-1000 DTY machine,which assures the oil flowing better.

Renovate the network air pipe for the 33H DTY machine which made in murata,the network DTY can be produced by the 33H DTY machine and the configuration of product can be improved.
