NT-STAT 52 is a thermally stable compound, which has been developed as a lubricant for texturising of nylon and polyester yarns. It is substantive to nylon and polyester and forms a strongly adherent film with the highest intermolecular cohesion, imparting low and uniform frictional properties to these fibres.

With regards to friction and lubrication of synthetic fibres, the behaviour of synthetic fibres can be divided into 3 categories, namely, the boundary, semi-boundary and hydrodynamic. The hydrodynamic friction is ascribed in the speed range above 5.5 meters per minute. It follows that intermittant contacts between fibres and substrate exist in the boundary region, whereas a continous fluid film seperates fibre from substrate in the hydrodynamic region.

NT-STAT 52 has high wetting property for nylon and polyester. This is clear from the surface tension data as under:
Nylon : 46 dynes / cm.
Polyester : 43 dynes / cm.
NT-STAT 52 : 30 dynes / cm.

This clearly indicates perfect wetting of NT-STAT 52 for those above two fibres.

Another important parameter in the fibre lubrication is lubricant viscosity. The viscosity of NT-STAT 52 is adjusted to reduce the sheer stress in the hydrodynamic region thereby decreasing the friction, in the boundary region, of course, the friction is independent of lubricant viscosity. It is worthwhile to mention that there is no significant difference between frictional behaviour at the fibre to metal and fibre to fibre interfaces.

Other Textile finishing oils and spin finishes are also available.
