> YARN SPINNING | ||||||||||
TongHui can supply melt or chip spinning
technology, know how as well as complete equipments for filament
production. POY can be taken up by full automatic or semi-automatic
winders, both godet and non-godet process shall be available. FDY spinning
process is almost similar with POY, after spinning, it's drawn by hot
godet rollers. |

> Staple Fiber Spinning Equipment Characteristics | ||||||||||
Polymer manifold is designed in optimization, gaseous dowtherm is applied for heating and insulation | ||||||||||
Spin packs are insulated uniformly, bottom mounted spin packs are used to save energy. | ||||||||||
Modified quench air system is applied for quench air system. | ||||||||||
Both single or double kissing roller technology can be viable. | ||||||||||
Reliable master batch system is applied for colored yarn production. | ||||||||||
Other auxiliary systems of AHU, cleaning system and spin finish preparation system shall ensure the quality of final products. | ||||||||||
> Technology Comparison |
||||||||||
Melt spinning: |
||||||||||
As drying and extrusion process are not required, it's the economic way to produce commodity in high capacity with uniform nice quality. |
||||||||||
Chip Spinning: |
||||||||||
It's viable for high value added specialty products' production, it's flexible for production change, bi-component products like orange splitting, core-peach and sea-island type shall be viable in chip spinning process. The shortage is small capacity and higher running cost. |
