Spinning System

Microfilament Spinning

Type of Microfilaments and Production Method

Normal Spinning by TMT's spinning system

The temperature and pressure of polymer inside the spin pack and spinneret capillary are kept uniform to prevent breaking of yarn and generation of a broken filament. In addition, the temperature in the annealing zone is maintained to be uniform and optimum, that enables reduction of dripping and ensure yarn quality.

CIQ(Circular Inflow Quench)

Advantage1

Efficiently Quench
Cool the melted yarn out of the spinneret efficiency by inflow method with the minimum possible quantity of quench air.

Advantage2

Reduces Air Consumption
Reduces Air Consumption – The amount of air used is only about 20%of the cross-flow method.

Advantage3

Execellent Quality
The stable production and the excellent quality for high count and micro filament such as 0.3 dpf equivalent to regular titer.

Advantage4

Space-Saving
The space-saving – dia. 85 spinneret enables to handle the high count yarn in excess of 288 filaments.
