Polyester DTY (polyester drawn yarn) is a common polyester product, widely used in textile, clothing, 

home textile and other fields. 75D polyester DTY means that the linear density of polyester yarn is 75 

decitex (dtex is the unit of linear density, 1 decitex is equal to 10,000 meters of polyester yarn weight 

1 gram).

The following is the production process of 75D polyester DTY:

1. Preparation of raw materials: The main raw material is polyethylene terephthalate (PET) chips, which 

are usually made from petrochemical products. At the same time, some auxiliary raw materials are also 

required, such as catalysts, stabilizers, etc.

2. Drying of chips: In order to ensure the smooth progress of the production process, the chips need to 

be dried to remove moisture from the chips.

Melt extrusion: The dried chips are placed in the extruder, heated at high temperature to melt them, and 

then the molten PET chips are extruded into continuous filaments under the action of the extruder.

4. Stretching: The extruded filament is stretched to reduce its linear density. Stretching can be performed 

on a single-stage stretching machine or a multi-stage stretching machine. According to different stretching 

multiples, polyester yarns with different linear densities can be obtained.

5. Winding and forming: The stretched polyester yarn needs to be wound and formed for subsequent 

processing and use. During the winding and forming process, the polyester yarn can be subjected to a certain 

heat setting treatment to improve its stability.

6. Post-processing: In order to improve the performance of polyester yarn, some post-processing can be 

performed, such as dyeing, printing, coating, etc.

7.Inspection and packaging: The completed polyester DTY is inspected to ensure that its quality meets the 

standards. Qualified products are packaged and prepared for shipment.

The above is the production process of 75D polyester DTY. In the actual production process, it is also necessary 

to adjust and optimize according to specific needs and equipment conditions.
