non-woven sanitary napkin material

When sourcing non-woven materials, you must prioritize absorbency, softness, and breathability. Key specs include GSM (Grams per Square Meter), typically ranging from 15-25 GSM for top sheets and 40-60 GSM for acquisition distribution layers (ADL). Ensure the material uses Spunbond or Hot Air-through technology to provide a cotton-like feel and prevent skin irritation. Additionally, verify the hydrophilic properties to ensure rapid liquid penetration while maintaining a dry surface.

As a hygiene product component, the material must meet strict safety standards. Ensure the supplier holds ISO 9001 for quality management and ISO 14001 for environmental standards. Crucially, products should be OEKO-TEX Standard 100 certified to guarantee they are free from harmful substances. For exports to the US or EU, check for FDA registration or CE marking compliance, and ensure the material passes biocompatibility tests (ISO 10993) for skin sensitization and irritation.

Request a technical data sheet (TDS) and physical samples for lab testing. Focus on the Strike-Through Time (how fast liquid passes through) and Wetback/Rewet values (how much liquid leaks back to the surface). For the top sheet, evaluate the tensile strength to ensure it doesn't tear during high-speed machine conversion. It is highly recommended to conduct a fluorescent agent test to ensure the material is 100% free from optical brighteners.

A standard napkin requires different layers: Hydrophilic Spunbond or Hot Air-through non-woven for the top sheet (skin contact), ADL (Acquisition Distribution Layer) to move fluid, and Hydrophobic Spunbond for the back sheet or side leak guards. For premium eco-friendly lines, consider Bamboo or Organic Cotton non-wovens, which offer higher biodegradable properties and market differentiation.

Always utilize third-party pre-shipment inspections (PSI) to verify that the roll width, diameter, and GSM match your order specifications. Since non-woven fabrics are sensitive to moisture and dust, insist on vacuum-sealed or heavy-duty PE film packaging with reinforced pallets.

Non-woven materials are high-volume but low-weight (volumetric cargo), so shipping costs are often calculated by volume. Optimize container loading by using 40HQ containers to reduce the per-unit freight cost. Ensure the warehouse environment is temperature-controlled and dry, as high humidity can degrade the hydrophilic coatings and affect the material's performance on the production line.

Raw material prices are often tied to Polypropylene (PP) resin market fluctuations. Negotiate a formula-based pricing model for long-term contracts. While standard MOQs are often 1 to 3 tons per specification, you can negotiate lower MOQs for trial runs by aligning your order with the supplier's existing production schedule. Always ask for volume-based discounts, which typically range from 5-10% for full container loads (FCL).

Check the HS Code (typically 5603) for specific import duties in your country. Be aware of anti-dumping duties that some regions impose on synthetic fibers. Ensure the supplier provides a Certificate of Origin (CO) to take advantage of preferential tariffs under trade agreements like RCEP or bilateral FTAs, which can significantly reduce your total landed cost.
