What GSM nonwoven fabric is used for a baby diaper topsheet?

Most commercial diaper topsheets use hydrophilic spunbond PP between 12 and 16 GSM. Premium and ultra-thin diapers go as low as 10 GSM; economy and adult-size products go up to 18 GSM. The right weight depends on your converting line speed and the absorbent core design underneath — a lighter topsheet needs a well-matched acquisition layer to avoid rewet.

What is the difference between hydrophilic and hydrophobic nonwoven for hygiene products?

Hydrophilic fabric is surface-treated to let fluid pass through quickly — it is used wherever liquid must reach the absorbent core, so topsheets and acquisition layers. Hydrophobic fabric repels fluid and is used wherever liquid must be held back: backsheets, leg cuffs and standing gathers. The treatment is applied at finishing and is specified per roll, so a single order can contain both.

Can Olefins match an existing diaper fabric specification?

Yes. Send your current specification sheet or a physical sample and we will produce a comparison sample matched on GSM, tensile strength, elongation, strike-through and hand feel. Sample dispatch is within 2 business days.

What is the minimum order quantity for hygiene nonwoven fabric?

Trial and development orders start at 1 metric tonne per specification. Regular supply is quoted per container or per monthly tonnage commitment. Contact us with your GSM, width and estimated monthly volume for exact MOQ and pricing.

Technical Specifications: What Makes Our Hygiene Fabric Different

Olefins hygiene nonwoven fabrics are engineered to meet the strictest requirements of disposable hygiene product manufacturers. Every roll is produced under ISO 13485:2016 quality management with full batch traceability from polymer to finished fabric.

1. Skin Safety & Biocompatibility

All hygiene grades are OEKO-TEX Standard 100 Class I certified — safe for direct prolonged contact with infant skin. We use only virgin polypropylene resin with no recycled content, optical brighteners, or harmful additives. Our fabrics pass ISO 10993 biocompatibility testing for cytotoxicity, skin irritation, and sensitization. This is critical for diaper topsheets and sanitary napkin coverstock where 24/7 skin contact occurs.

2. Advanced Hydrophilic Treatment Technology

Our proprietary durable hydrophilic finish ensures rapid liquid acquisition while maintaining low rewet values even after multiple insults. Unlike topical surfactants that wash off, our treatment is integrated into the fiber matrix during spinning. Result: strike-through time ≤3 seconds and rewet ≤0.2g per EDANA WSP 70.3 standard. We also offer permanent hydrophilic grades for adult incontinence products requiring 8+ hour wear time. For more details see our complete guide to adult incontinence fabric specifications.

3. GSM Consistency & Roll Uniformity

Using Reicofil 4S technology with in-line beta-gauge monitoring, we maintain GSM tolerance of ±3% across the full 3.2m roll width. This consistency is non-negotiable for high-speed converting lines running 600+ diapers per minute. Uneven GSM causes web breaks, misalignment, and waste. Every Olefins shipment includes a GSM uniformity report with 5-point measurements per roll.

Custom Development & OEM Supply Process

We partner with hygiene brands to develop custom nonwoven specifications for new product launches or cost-optimization projects.
