Hydrophilic non-woven fabric guide

Hydrophilic Nonwoven

Hydrophilic Nonwoven Fabric: A special type of nonwoven material opposite to hydrophobic nonwoven fabric. This material gains hydrophilic properties by adding a hydrophilic agent during the nonwoven fabric production process or directly into the fibers during fiber production. The main features of hydrophilic nonwoven fabric are its excellent water absorption and retention properties, allowing it to quickly absorb and retain moisture, providing a more comfortable user experience.

Scientific Principles of Hydrophilic Nonwoven Fabric

Nonwoven fabrics are typically made from high molecular weight polymers, which usually have few or no hydrophilic groups, resulting in poor hydrophilic performance. To improve this property, scientists add hydrophilic agents during the production process of the nonwoven fabric or fibers.

The hydrophilic agent mainly works by increasing the surface tension of the fibers and reducing the contact angle between the nonwoven fabric and water. The contact angle is a physical quantity that describes the degree of wetting of a liquid on a solid surface. A smaller contact angle indicates higher wettability, meaning better hydrophilicity. Therefore, by adding a hydrophilic agent, the surface tension of the nonwoven fabric is increased, and the contact angle with water is reduced, thus achieving hydrophilic modification of the nonwoven fabric.

Physical Properties of Hydrophilic Nonwoven Fabric

  1. Softness: Hydrophilic nonwoven fabrics are usually made from processed synthetic fibers, which are soft, making the overall texture of the nonwoven fabric gentle and comfortable, with excellent skin-friendly properties.

  2. Breathability: The structural characteristics of nonwoven fabrics allow air and moisture to pass through freely, preventing the accumulation of heat or moisture and effectively avoiding discomfort or irritation. This breathability makes hydrophilic nonwoven fabric widely applicable in medical, hygiene, and clothing fields.

  3. Water Absorption: This is one of the most significant characteristics of hydrophilic nonwoven fabric. By adding a hydrophilic agent, the surface tension of the nonwoven fabric is increased, enabling it to quickly and effectively absorb moisture from the skin or other surfaces. This high absorbency makes hydrophilic nonwoven fabric widely applicable in medical dressings, hygiene products, cleaning supplies, and more.

Functions and Advantages of Hydrophilic Nonwoven Fabric
