Textile Filament Yarn Industry Lubricants

Product Details:

CVC SILCOLEASE (FR) is high grade custom formulated Silicone based heavy duty release agent for synthetic fibres such as Nylon, Polyesters, Acrylics, etc. It is formulated with thermally stable Silicones, which resist high temperature with low volatility. It is regularly sprayed on spinnerets through which synthetic filament yarn is drawn, so that sticking of filaments with one another or with spinneret is avoided. It also makes higher temperature extrusion possible to increase production of synthetic filaments. The product can also be formulated in line with the quality of silicone (for long life, high temperature) & its content and type of propellant (flammable / non-flammable) to meet the customers requirements.

 

Note: These are typical specifications, which may vary based on the propellant filled in Aerosol can. It is available in 3 different types of propellants viz. LPG, CO2 and F134a. Also tailor-made formulations can be offered for any particular requirement.

Area of Application:

 

• On the spinnerets of spinning melt systems for Synthetic fibres. As a high temperature lubricant for Bearings, Chains, Gears, Guides etc.

Benefits:

• Non-sticking Release Spray
• Less volatility at high temperature
• Extended Cleaning intervals
• Non-Toxic & Non-Flammable

Packing: 550-ml. Aerosol Tin

Product Details:

NT-STAT 40/52 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.
CHARACTERISTICS TYPICAL VALUES1. Appearance / Colour (Visual) … Clear / Pale Yellow2. Emulsion Stability … Stable White3. Viscosity @ 40°C … 204. Specific Gravity @RT°C … 0.855. Surface Tension … 30 dynes per cm.6. Ionogenity … Non-ionic7. Recommended Dosage … 0.7 - 1% by weight of yarn 
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 continuous fluid film separates 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 dataas 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.Packing: 27-Litre & 210-Litre drums
