Specialized Services:

Melt Polymer Transfer Line Design:

DDS has gained expertise in Polymer Transfer Line Design.

Polymer transfer line transports melt polymer from continuous polymerisation (CP) plant to yarn spinning machines – POY/FDY/PSF.

The temperature of Polymer is more than 280˚C and the pressure is more than 150 bar. At such a high temperatures and pressures, polymer quality deteriorates until it reaches the spinning machines.

To have uniform quality of polymer at all spinning positions, an accurate design of Polymer melt transfer line is very significant and consequential. A special pressure drop and residence time calculation (PDRTC) is devised to achieve uniform residence time for polymer, reaching every spinning machine.

In earlier days, CP capacities used to be small—about 200 TPD and distribution length of melt polymer to spinning machines was short. With the increase in CP capacities, for direct melt spinning, the number of spinning machines has increased, the network of polymer lines has become complex and extensive, and the lengths have become longer. To achieve uniform residence time for such large capacities, DDS has developed unique software and techniques. Stress analysis of all the Polymer melt lines and the heating HTM lines needs to be performed.

Currently, DDS is the leading designer for the Polymer Melt Transfer Line in India.

Over the last 6 years, we have successfully designed many Polymer Melt Transfer Lines.

Recently, DDS completed the detail-engineering of Polymer Transfer Line for Bhilosa Industries, for its CP4/5 Project (1680 tpd- POY/FDY/PSF) and it has been running successfully. We have satisfactorily completed transfer line jobs at WellKnown Polyester, Sanathan Textiles, DNH Spinners, Aditya Birla, Koza Polyester and the addition of Polymer cooler in SASA, redesigning some of the existing transfer lines at Indorama Indonesia.
At present, we are working on the detailed design of Polymer Transfer Line for Bhilosa’s CP2/3/6 (1650 TPD POY/FDY), Beekaylong, 300 mt FDY Transfer line work at GSMPL (through Oerlikon).

Continuous Polymerisation (CP) Plant:

DDS has ventured into Basic and Detail designing of  Continuous Polymerisation (CP) Plant .

Recently, DDS executed a CP project of 70 tpd capacity, which is running successfully.

DDS has designed all the rectors and equipment.

DDS has done its complete detail engineering.

DDS is now equipped with facilities to cater CP plants of various capacities, up to 400 tpd.

Texturizing Oil plant:

DDS has developed the technical know-how of a Texturizing Oil plant (also known as a Conning Oil plant for DTY Machines).

DDS has successfully done the basic design and detail engineering of a 100 tpd Texturizing Oil Plant, which is operating successfully with consistent quality. It had a very optimal payback.

DDS can cater to Texturizing Oil plant of any capacity.
