FUNCTIONAL ADDITIVE
W329
W329 High-Performance Multi-Use Hydrophilic Oil
For multi-use hydrophilic finishing of spunbond and SMS nonwovens, with strong wettability, soft hand feel and hygiene-grade performance.
Spunbond nonwovenSMS nonwovenHygiene topsheet
W329 suits spunbond and SMS nonwovens with demanding wettability and multi-strike performance. Apply it as an aqueous emulsion (5%-12%) at a recommended add-on of 0.5%-1.0%. If solids precipitate at low temperature, warm the product to 30-40°C and mix well before emulsifying. We recommend fabric trials to confirm the actual process window.
