Introduction

Why Nonwoven Fabric Is the Top Choice for Sanitary Pads

1. Ultra-Soft and Skin-Friendly

2. Excellent Air Permeability

3. Fast Absorbency and Leakage Prevention

4. Hygienic and Disposable

5. Lightweight and Flexible

6. Durable and Not Easy to Tear

Introduction: Why Nonwoven Fabric Is Essential in Sanitary Pad Manufacturing

The sanitary pad industry requires materials that can provide:

• softness

• liquid management

• breathability

• skin comfort

• production efficiency

A modern sanitary pad is not made from a single material. It is a multi-layer hygiene product composed of different functional materials, and each layer has a specific purpose.

Among these materials, nonwoven fabric plays an important role because it provides a combination of softness, strength, filtration performance, and cost efficiency.

Common nonwoven materials used in sanitary pad manufacturing include:

• PP spunbond nonwoven fabric

• spunlace nonwoven fabric

• SMS nonwoven fabric

• hydrophilic treated nonwoven fabric

For manufacturers, selecting the correct nonwoven material directly affects:

• product quality

• consumer comfort

• production stability

• market competitiveness

1. What Is Nonwoven Fabric Used in Sanitary Pads?

Definition of Nonwoven Fabric

Nonwoven fabric is an engineered textile material made by bonding fibers together through mechanical, thermal, or chemical processes without traditional weaving or knitting.

Unlike woven fabrics, nonwoven materials are produced directly from fibers, allowing manufacturers to customize:

• softness

• thickness

• absorbency-related performance

• strength

• surface properties

Basic Structure of a Sanitary Pad

A typical sanitary pad consists of several layers:

Top Sheet
     ↓
Acquisition Distribution Layer (ADL)
     ↓
Absorbent Core
     ↓
Back Sheet
     ↓
Release Paper

Different layers require different materials.

Role of Nonwoven Fabric in Sanitary Pads

Nonwoven materials are mainly used in:

1. Top Sheet

The top sheet is the layer directly contacting the skin.

Requirements:

• soft touch

• rapid liquid penetration

• comfortable feeling

Common materials:

• hydrophilic PP spunbond

• spunlace

2. Acquisition Distribution Layer (ADL)

The ADL helps:

• distribute liquid quickly

• reduce surface wetness

• improve absorption efficiency

Requirements:

• good liquid transfer

• suitable fiber structure

3. Back Sheet Support Layer

Some sanitary pad structures use nonwoven materials as supporting layers.

Requirements:

• strength

• dimensional stability

2. Why Nonwoven Fabric Is Used in Sanitary Pads

Advantage 1: Softness and Skin Comfort

Comfort is one of the most important factors in sanitary products.

Consumers expect:

• smooth surface

• low irritation

• comfortable wearing experience

Softness is influenced by:

• fiber diameter

• bonding method

• surface treatment

• fabric structure

For premium sanitary pads, manufacturers often choose materials with:

• finer fibers

• softer surface

• better drape performance

Advantage 2: Excellent Liquid Management

Sanitary pad materials must quickly handle liquid.

The top layer should allow:

• fast penetration

• reduced surface wetness

• efficient transfer

Hydrophilic treated nonwoven fabrics improve:

• liquid absorption speed

• user comfort

Advantage 3: Breathability

Breathability is important because hygiene products are worn for extended periods.

A breathable structure helps:

• reduce heat accumulation

• improve comfort

• manage moisture

Compared with traditional plastic-like materials, nonwoven fabrics provide better air exchange.

Advantage 4: Production Efficiency

Sanitary pad manufacturers require materials suitable for high-speed production.

Nonwoven fabrics provide:

• stable quality

• uniform thickness

• easy processing

Suitable for:

• high-speed converting machines

• lamination

• bonding processes

Advantage 5: Cost Efficiency

Sanitary products are highly competitive.

Manufacturers need materials that balance:

• performance

• quality

• cost

PP spunbond nonwoven fabric is widely used because it provides:

• reliable performance

• large-scale availability

• competitive pricing

3. Types of Nonwoven Fabric Used in Sanitary Pads

Different applications require different nonwoven structures.

3.1 PP Spunbond Nonwoven Fabric

Definition

PP spunbond nonwoven fabric is produced by extruding polypropylene into continuous filaments and bonding them through thermal processes.

Key Advantages

1. Strength

Provides:

• good tensile strength

• dimensional stability

• processing reliability

2. Breathability

The fiber network allows:

• airflow

• moisture exchange

3. Cost Advantage

Compared with some specialty nonwoven materials:

• lower cost

• stable supply

• suitable for mass production

Applications in Sanitary Pads

PP spunbond is commonly used for:

• top sheet materials

• acquisition layers

• supporting layers

3.2 Spunlace Nonwoven Fabric

Spunlace is manufactured using high-pressure water jets to entangle fibers.

Advantages

• excellent softness

• textile-like feeling

• premium appearance

Applications

Often used in:

• premium sanitary pads

• feminine care products

• products requiring superior comfort

Limitation

Compared with PP spunbond:

• higher cost

• different supply structure

3.3 SMS Nonwoven Fabric

SMS structure:

Spunbond
    ↓
Meltblown
    ↓
Spunbond

Advantages:

• stronger barrier performance

• improved protection

Applications:

• specialty hygiene products

• medical-related hygiene applications

4. Hydrophilic Nonwoven Fabric for Sanitary Pads

Hydrophilic treatment is one of the most important technologies in sanitary pad materials.

What Is Hydrophilic Nonwoven Fabric?

Hydrophilic nonwoven fabric is a material treated to improve water absorption and liquid penetration.

Why Is Hydrophilic Treatment Needed?

Standard polypropylene is naturally hydrophobic.

This means:

• water does not easily spread

• liquid penetration can be slow

Hydrophilic treatment improves:

• liquid absorption speed

• surface dryness

• user comfort

5. How to Choose GSM for Sanitary Pad Nonwoven Fabric

GSM affects:

• softness

• strength

• thickness

• cost

Common GSM ranges:

However:

Higher GSM does not always mean better sanitary pad performance.

The ideal GSM depends on:

• product design

• softness requirements

• machine capability

• target market
