Stretching And Twisting
Stretching is an essential and important process in fiber manufacturing, which has a significant impact on the quality of fibers. After stretching, polyester filament is wound into a tube. Due to the fact that most equipment’s winding device is a ring ingot, a certain degree of twist is add...Read more -
Selection of Spinning Process Parameters
The process parameters during spinning determine the changes in fiber formation, and significantly influence spinnability, the structure and properties of the wound yarn, as well as the characteristics of the finished filament. 1. Melt Temperature Also referred to as spinning temperature, it is d...Read more -
Judgment on the Spinnability of Chips
The spinnability of polyester chips has a critical impact on filament production. Good spinnability of polyester chips results in strong adaptability to the process, a stable production process, and high quality of the processed products. Characteristics of Spinnability Performance 1.Pressure Inc...Read more -
Polyester Spinning Principle
Polyester fiber spinning is a complicated physical change process. In this process, with the transfer of heat and force, polymer undergoes solid (chip)-liquid (melt)-solid (fiber) changes. These changes have an important influence on fiber properties. 1.Melt polymer pre...Read more -
What is the process flow of spinning
Spinning process flow The conventional melt spinning process is as follows: dry slicing → melt extrusion → mixing → metering → filtration → spinning → cooling and forming → oiling → winding → UDY tube Due to impurities in the melt, filtration is required before spinning....Read more -
Cleaning-Spinning components, Metering pumps & Melt filters
PREFACE: Spin pack components, metering pump and candle filter will all be clogged with dirt after being used for a certain period of time. The pressure of the spinning components and the pressure difference between the inlet and outlet of the melt filter will i...Read more -
What indicators and parameters of polyester chips affect filament quality?
The quality of polyester chips not only affects the quality of PET filament, but also affects the normal production of POY, FDY filament spinning. Therefore, to prepare high-quality filament products, polyester chips must be strictly selected. Filament-level slices shoul...Read more -
What is the production process of polyester filament?
Introduction: POY & FDY filament spinning, BCF spinning and polymer spinning all require filtration before spinning. Futai can provide stainless steel metal sand, spin pack filter, candle filters, leaf disc filters, filtration equipment and other filtration products ...Read more -
Cleaning of Candle Filter
After the candle filter element is used for a period of time on the filament spinning line, it will be blocked by dirt, and the pressure difference between the inlet and outlet of the melt polymer filtration system will increase, and these pleated candle filter needs to ...Read more
