Does the water absorption of hydrophilic non-woven fabric have obvious characteristics and advantages?

Hydrophilic non-woven fabric is a specially treated non-woven material, and one of its most notable characteristics is its excellent water absorption. Through surface treatment or the addition of hydrophilic agents, non-woven fabrics can quickly absorb and lock liquids while keeping the surface dry. This feature makes it widely used in sanitary products (such as baby diapers, sanitary napkins for women) and medical supplies (such as surgical dressings, medical gauze).

Characteristics of water absorption of hydrophilic non-woven fabrics

The water absorption of hydrophilic non-woven fabrics is achieved in the following two main ways:

1. Surface treatment: Modify the surface of non-woven fabrics by physical or chemical methods to increase its surface energy, making it easier to absorb liquids.

2. Add hydrophilic agent: Add hydrophilic agents (such as surfactants) during the production process of non-woven fabrics to make the fiber surface hydrophilic, thereby improving the liquid absorption capacity.

Advantages of hydrophilic nonwoven absorbency
1. Reduce liquid back-osmosis
High water absorbency allows liquid to be quickly absorbed and locked inside the nonwoven, thereby reducing liquid back-osmosis to the surface. This feature is particularly important in sanitary products (such as baby diapers and feminine sanitary napkins), which can significantly improve the comfort of users.

2. Improve comfort of use
Because the liquid is quickly absorbed and locked, the hydrophilic nonwoven can keep the surface dry, reducing moisture and discomfort. This is particularly important in medical products (such as surgical dressings and medical gauze), which can reduce skin irritation and infection risks.

3. Improve product performance
High water absorbency makes hydrophilic nonwovens excellent in liquid management, thereby improving the overall performance of related products. For example, in baby diapers, high water absorbency can reduce leakage; in medical dressings, high water absorbency can accelerate wound healing.

Water absorption test method
In order to evaluate the water absorption of hydrophilic non-woven fabrics, the following test methods are usually used:
1. Liquid absorption rate test
The liquid absorption speed of non-woven fabrics is evaluated by measuring the amount of liquid absorbed by non-woven fabrics per unit time. The faster the absorption rate, the better the hydrophilicity of the non-woven fabric.
2. Water retention capacity test
The water retention capacity of non-woven fabrics is evaluated by measuring the amount of liquid that non-woven fabrics can lock after absorbing liquid. The stronger the water retention capacity, the better the liquid management performance of non-woven fabrics.
3. Liquid distribution uniformity test
The liquid absorption uniformity is evaluated by observing the distribution of liquid in non-woven fabrics. Uniform liquid distribution helps to improve the use effect of the product.
Why was hydrophilic non-woven fabric invented?
1. Meet the needs of efficient liquid management
In sanitary and medical products, liquid management is a core issue. Traditional non-woven fabrics often cannot absorb and lock liquids quickly due to their lack of hydrophilicity, resulting in liquid reverse osmosis and surface moisture. The invention of hydrophilic nonwoven fabrics is to solve this problem, by improving water absorption to meet the needs of efficient liquid management.

2. Improve the comfort and safety of use
In sanitary products (such as baby diapers and sanitary napkins for women), liquid reverse osmosis and surface moisture can cause discomfort to users and even cause skin problems. In medical products (such as surgical dressings and medical gauze), improper liquid management may lead to an increased risk of infection. Hydrophilic nonwoven fabrics significantly improve the comfort and safety of use through high water absorption.

3. Promote product innovation
The invention of hydrophilic nonwoven fabrics provides new possibilities for the innovation of sanitary and medical products. For example, highly absorbent nonwoven fabrics can be used to develop lighter, more comfortable baby diapers, or to make more efficient medical dressings.

4. Adapt to the trend of environmental protection and sustainable development
With the increase of environmental awareness, the production of hydrophilic nonwoven fabrics has gradually developed in a sustainable direction. For example, the use of degradable materials to make hydrophilic nonwoven fabrics not only meets the needs of efficient liquid management, but also reduces the impact on the environment.
