Melt spinning is a typical spinning of synthetic fiber such as Polyester, Nylon, Polypropylene. Melted polymer is discharged from the spinneret.
The discharged fiber is wound after quenching process and drawing process.Melt spinning is used for various polymers and applications.
|Material||Stainless steel, others|
|Application||Textile, Industrial yarn|
|Hole size||Round/irregular-shaped hole range 0.1mm dia to 3.0mm diat|
|Hole diameter||L/d||Accuracy of hole diameter||Accuracy of capillary length|
■Irregular shaped hole
|Slit width||L/W||Accuracy of slit width||Aaccuracy of capillary length|
By coating on the nozzle surface, various performance can be given.Optimum coating materials can be selected depending on the raw materials used, spinning and cleaning condition.
It also contributes to cost saving such as extended life time and maintenance during operation.
■Typical example of coating we can make
|coating with single element||coating with mixed plural elements||special coating|

By changing polymer combination and spinning condition, fiber spun from irregular shaped hole can obtain various type of characteristic.The hole shape is selected based on required performances.
