Technology And Industrialization Of Direct Spinning Polyester Industrial Filament With Liquid Viscosity Increasing Melt

In polyester,

We have rich experience in technology and chemical fiber equipment, and provide guidance for the smooth implementation of the project, and lead the team to solve a series of problems related to the polyester industrial yarn industry.

In the process of R & D and industrialization development of liquid phase thickening melt direct spinning polyester industrial yarn, we participated in the process.

The design and structure optimization of the thickening reaction kettle, the development of polyester polymerization process and liquid phase visbreaking process have solved many problems encountered in the first industrialization of liquid phase viscosity increasing technology. During the subsequent spinning process, the spinning process design and production control have been involved, and the corresponding spinning process has been developed according to the uniqueness of the high viscosity polyester melt and liquid phase viscosity increasing technology.

Main innovation points of the project

1. we have successfully developed and produced 200 thousand tons liquid phase thickening melt direct spinning polyester industrial yarn production technology and complete set of equipment technology.

2. independently develop and develop high-energy liquid phase thickening reactor and viscosity increasing process, and realize 98 flexible production lines with 1 heads and 9 cauldron.

3. a material pressure balance pipeline is set up to control the height of the liquid level in the viscosity increasing reactor and ensure the stable quality of the melt.

4. in the field of polyester industrial yarn design and implementation of high capacity multi head coarse denier spinning integrated technology, the maximum size of the single spun yarn reaches 18000D, up to 24 spinning.

The technology has been industrialized in Zhejiang's new material Limited by Share Ltd, in July 2011, the 200 thousand ton liquid phase viscosity increasing melt direct spinning polyester industrial yarn production line was successfully put into operation.

From August 2011 to December 2013, the project achieved sales income of 4 billion 346 million yuan.
