Hydrophilic Masterbatch

Application notes

This hydrophilic masterbatch is developed for PP spunbond lines serving hygiene and medical nonwoven applications — typically topsheet or acquisition layers where controlled fluid handling is required. The typical dosage range of 5–7% is a starting window; the final level is matched to the resin, fabric construction, and the required wetting or strike-through test.

A hydrophilic result is shaped by more than the additive. Fabric structure (spunbond, SMS, or composite), basis weight, target layer, conditioning time, and storage conditions all influence the measured wetting behavior. One addition level cannot be assumed across all lines and structures — a level that performs on a spunbond topsheet may need adjustment for an SMS composite or a different basis weight.

Durability expectations should be stated explicitly. Whether the requirement is single strike-through, repeat wetting, or performance after storage, the test method and acceptance criteria need to be defined before the trial so results can be judged against a clear target. Record resin, addition level, line settings, fabric construction, test method, and conditioning time during trials so the outcome is reproducible.
