Quick Answer: Hydrophilic nonwoven fabric absorbs and transfers water — used in the topsheet and ADL layer of sanitary pads and diapers. Hydrophobic nonwoven fabric repels water — used in the backsheet and outer cover. Both types are essential in every hygiene product, just in different layers.

Hydrophilic vs Hydrophobic Non Woven Fabric: Key Differences, Properties & Uses
Hydrophobic and hydrophilic nonwoven materials are two types that are sometimes confused with each other. Understanding the hydrophilic hydrophobic difference is essential for manufacturers, buyers, and product designers working with hygiene, medical, and industrial nonwoven fabrics.
The names come from Latin roots — “hydro” means water, “philic” means loving, and “phobic” means fearing. So hydrophilic nonwoven loves water and absorbs it, while hydrophobic nonwoven fears water and repels it.
Which is Used in Sanitary Pads and Diapers — Hydrophilic or Hydrophobic?
Both types are used in every sanitary pad and diaper — just in different layers. Getting this right is critical for product performance and user comfort:
| Layer | Type Used | Why |
|---|---|---|
| Topsheet (skin contact) | ✅ Hydrophilic | Fluid must pass through quickly into core |
| ADL / Acquisition Layer | ✅ Hydrophilic | Spreads fluid evenly across absorbent core |
| Absorbent Core wrap | ✅ Hydrophilic | Allows fluid entry into SAP and fluff pulp |
| Backsheet (outer cover) | ✅ Hydrophobic | Blocks fluid from leaking through to clothing |
| Side leak guards | ✅ Hydrophobic | Prevents side leakage |
| Outer diaper cover | ✅ Hydrophobic | Keeps outside of product completely dry |
The topsheet that touches skin uses hydrophilic nonwoven so fluid passes through quickly into the core below. The backsheet on the outside uses hydrophobic nonwoven or PE film to prevent any fluid leaking out. Using the wrong type in either layer will cause immediate product failure — either the pad will not absorb, or it will leak through the back.
What is the Difference Between Hydrophilic and Hydrophobic Nonwoven?
Water is a polar molecule and an excellent solvent. However, not all substances mix with water — and this is the core principle behind hydrophilic and hydrophobic materials.
- Hydrophilic materials are polar — they mix with, absorb, and are attracted to water molecules
- Hydrophobic materials are nonpolar — they cannot dissolve in or mix with water and actively repel it
In nonwoven fabrics, this difference is achieved either through fiber selection or surface treatment. Naturally hydrophobic fibers like polyester can be converted to hydrophilic by adding surfactants, wetting agents, or rewetting agents during manufacturing. Conversely, naturally absorbent fibers like cotton can be treated with coatings to make them hydrophobic.

What is Hydrophilic Non Woven Fabric?
Hydrophilic nonwoven fabric actively absorbs and transfers water. The term hydrophilic comes from hydro (water) and philic (loving) — a nonwoven fabric that has an affinity for water and wicks moisture rapidly.
Fabrics with hydrophilic finishes attract water and transfer it through a process known as wicking or moisture management — pulling fluid away from the skin surface and into the absorbent core below.

What is Hydrophobic Non Woven Fabric?
Hydrophobic nonwoven fabric repels water and prevents liquid from passing through it. It has very low absorbency and excellent barrier stability — making it ideal for outer layers and backsheets where keeping moisture out is essential.
Polyester is a naturally hydrophobic fiber. Polypropylene spunbond nonwoven is also naturally hydrophobic when untreated. Hydrophobic nonwoven fabrics have gained attention especially in medical and hygiene applications because they are cost-effective, flexible, environmentally manageable, and easy to manufacture at scale.

- Side leak guard barriers in hygiene products
- Surgical gowns, drapes, and protective covers
- Disposable medical items and wound covers
- Filter materials and compound packing
- Tablecloths and disposable tabletop products
- Personal healthcare and protective products
Application of Hydrophobic Nonwovens in Medical Textiles
Hydrophobic nonwoven fabrics have successfully replaced conventional barrier medical textiles in many applications. Their key advantages in medical use are that they are disposable, single-use safe, cost-effective, and can be produced from eco-friendly natural fibers. Medical applications include:
- Medical device implant covers
- Separation gowns and surgical drapes
- Surgical coverings and sterile wraps
- Protective gloves and barrier products
- Wound dressings outer barrier layer
- Pharmaceutical packaging
- Surgical masks outer layer
Is Rayon Hydrophilic or Hydrophobic?
Rayon is hydrophilic. It is a regenerated cellulose fabric produced by dissolving and wet-spinning cellulose derived from wood and cotton. As a cellulose fiber, rayon actively absorbs water — making it more absorbent than cotton.
Rayon nonwoven is widely used in cosmetic mask packs, medical applications, and hygiene products precisely because of its hydrophilic properties. It gives exceptional performance when paired with hydrophobic polyester — combining absorbency with structural strength. Key properties of rayon that make it valuable include softness, breathability, biodegradability, excellent moisture absorption, and a silky drape.

FAQs — Hydrophilic vs Hydrophobic Non Woven Fabric
What is the difference between hydrophilic and hydrophobic nonwoven fabric?
Hydrophilic nonwoven absorbs and transfers water — used in skin-contact layers of sanitary pads and diapers. Hydrophobic nonwoven repels water — used in outer backsheet layers to prevent leakage. Both types are used in every hygiene product in different layers.
Which nonwoven is used in sanitary pad topsheet?
Hydrophilic nonwoven is used in the topsheet of sanitary pads. It allows menstrual fluid to pass through quickly to the absorbent core below while keeping the surface feeling dry against skin. Typically 15–20 GSM hydrophilic PP spunbond or perforated PE film is used.
What is hydrophilic nonwoven fabric used for?
Hydrophilic nonwoven is used in sanitary pad topsheet, diaper inner layer, baby wipes, cosmetic face masks, medical wound dressings, and any application requiring rapid fluid absorption and skin-safe comfort.
Is polyester hydrophilic or hydrophobic?
Polyester is naturally hydrophobic — it repels water. However polyester can be treated with surfactants and wetting agents to make it hydrophilic for use in hygiene topsheet applications. Untreated polyester nonwoven is used in backsheet and outer barrier applications.
What is hydrophilic fiber definition?
Hydrophilic fibers have water-loving properties and are used in materials where liquid absorbency is required — such as sanitary napkins, baby diapers, adult diapers, tampons, and medical wipes. Examples include cotton, viscose, rayon, and surfactant-treated polypropylene.
Where can I find hydrophilic and hydrophobic nonwoven fabric manufacturers in India?
Favourite Fab manufactures and supplies both hydrophilic and hydrophobic nonwoven fabrics in India. We are one of India’s top SMMS fabric manufacturers with ISO, GMP, and FDA certifications. MOQ 1000 kg. Contact us for pricing.
Conclusion
Understanding the difference between hydrophilic and hydrophobic nonwoven fabric is fundamental for anyone involved in hygiene product manufacturing. Hydrophilic nonwoven enables rapid fluid transfer in skin-contact layers while hydrophobic nonwoven creates the essential leak-proof barrier on the outside. Together they work in every sanitary pad, diaper, and incontinence product to deliver comfort, dryness, and protection. Contact Favourite Fab to source both types with bulk pricing and certified quality.
