Choosing a Calcium PP Filler for Hygiene-Grade Non-Woven Fabric

What Is It?

Hygiene-grade non-woven fabric — the spunbond topsheet and backsheet layers, and meltblown filtration layers, used in diapers, sanitary napkins, and adult-incontinence products — sits in direct, sustained contact with skin, which raises the bar for both softness and defect-free consistency well above general industrial non-woven fabric. Nexxa's calcium PP filler for this segment is formulated at the same 80–82% CaCO₃ loading and MFI 25 ± 5 as the standard non-woven grade, but the emphasis in qualifying it for hygiene converters sits specifically on dispersion quality and melt-flow stability at the fine-denier, high-speed settings hygiene lines typically run at.

How It's Manufactured

The filler is compounded on twin-screw extruders inside a highly automated plant, with production capacity dedicated to this line so hygiene-fabric converters receive the same loading and melt-flow characteristics lot after lot — a non-negotiable requirement in hygiene manufacturing, where fabric softness, basis weight, and coverage are tightly specified and routinely audited by the converter's own quality system. Nexxa's dedicated in-house R&D team, drawing on fifteen years of process experience with this specific compound, holds dispersion and MFI within tolerance through in-process testing on every batch rather than relying solely on a final release check.

Manufacturing Process for This Application

Hygiene non-woven producers typically run fine-denier spunbond or meltblown lines at high line speed to hit the tight cost-per-part economics that mass hygiene-product manufacturing demands — speed and fineness that leave very little margin for a filler with inconsistent dispersion. A filler that disperses unevenly at these settings produces filament breaks and visible speckling that force a line to slow down, or worse, to scrap output that fails inspection after the fact. Because Nexxa's formulation work for this grade specifically targets fine-denier, high-speed processing rather than general-purpose non-woven conditions, converters can run at their intended speed without derating the line to compensate for filler inconsistency.

Why Polymer Choice Matters Here

A hygiene product's non-woven layer is inspected — by machine vision on the line and often by hand downstream — for exactly the defects an inconsistent filler introduces: harsh or uneven patches from loading variance, visible specks from poor CaCO₃ dispersion, and weak points that could tear during converting or in the finished product. Getting the filler right here isn't just a processability question, it's a direct pass/fail quality gate on a product that touches skin. The right calcium PP filler holds down material cost — the entire economic rationale for using a filler at all — while keeping the fabric soft, uniform, and free of the defects that fail a hygiene converter's inspection standards.
