What is hydrophilic non woven fabric

Hydrophilic nonwoven fabrics are made by adding "hydrophilic" chemicals to nonwoven fabrics.

Most of the nonwovens themselves are not hydrophilic or are outright water-repellent. To make the nonwoven fabric hydrophilic. The hydrophilic agents are added to the nonwoven fabric production process. or added to the fibers during the fiber production process, which is called hydrophilic nonwoven fabric.

Hydrophilic nonwovens are widely used in medical, hygiene, household, cosmetic, and industrial applications. For example, in the medical and hygiene fields, hydrophilic nonwovens are commonly used to make products such as medical dressings, sanitary napkins, diapers, and surgical gowns, which need good water absorption and permeability to ensure good comfort and protection.

What is a hydrophilic agent?

First of all, we have to understand that nonwoven fabric is a kind of nonwoven fabric. Due to the special nature of its fiber structure and manufacturing process. It makes the nonwoven fabric more helpful than traditional fabric in some aspects, such as lighter, softer, more breathable, and easier to handle.

In the production of hydrophilic nonwovens, hydrophilic agents are usually added to the fiber blend of the textile material or through the next chemical treatment process.

This treatment allows the surface of the nonwoven to be more easily wetted with water and thus has good water absorption and liquid permeability properties.


What are the advantages of hydrophilic?

1. Hydrophilic

Compared with ordinary nonwoven fabric, hydrophilic nonwoven fabric has good hydrophilic performance. I.E. hydrophilic rate, hydrophilic speed, hydrophilic validity, and hydrophilic times, which can quickly absorb moisture and keep the surface dry and not easy to slip off.    

To progress the hydrophilicity of the nonwoven fabric, hydrophilicity is generally achieved by progressing the wetness of the appearance.

2. Air permeability

The breathability of the hydrophilic nonwoven fabric is good. It allows air to circulate freely and does not affect skin breathing.

3. Softness

The hydrophilic nonwoven fabric has finer fiber thickness and a softer texture. It is comfortable to the touch and not easy to stimulate the skin.

4. High strength

After a special process and can withstand certain weights and tension. The fibers of the hydrophilic nonwoven fabric have high strength and tensile properties.

5. Corrosion resistance

The hydrophilic nonwoven fabric has good chemical stability and good corrosion resistance.

6. Safety and hygiene

Hydrophilic nonwoven fabric is an environmentally friendly material. It does not contain toxic and harmful substances and is harmless to the human body. And it meets hygiene standards.

7. Isolation of bacteria

The surface of the hydrophilic nonwoven fabric has good antibacterial properties. It can effectively isolate and kill bacteria and keep the surface clean and hygienic.


Uses of hydrophilic nonwovens.

Hydrophilic nonwovens are used in a wide range of applications. With important applications in medical, hygiene, daily necessities, and industrial fields. The main applications of hydrophilic nonwovens due to their good moisture absorption, breathability, and antibacterial properties include the following.

1. Medical and health care

Hydrophilic nonwoven fabrics can be used to make medical masks, medical bandages, surgical gowns, isolation gowns, sanitary napkins and other products for medical and health purposes.

2. Baby products

Hydrophilic nonwoven fabrics can be used to make diapers, diaper pads, wet wipes, baby washcloths, and other baby products.

3. Daily necessities

Hydrophilic nonwoven fabrics can be used to make daily necessities such as washcloths, facial cleansing pads, skin care towels, slippers, etc.

4. Cleaning products

Hydrophilic nonwoven fabrics can be used to make dish towels, wipes, window wipes, floor wipes, and other cleaning products. They can quickly absorb and remove dirt and liquid. 

5. Industrial products

Hydrophilic nonwoven fabrics can be used to make filter materials, isolation materials, insulation materials, wiping cloths, protective clothing, and other industrial supplies.

6. Agricultural supplies

Hydrophilic nonwoven fabric can be used in the agricultural field, such as cover crop film, greenhouse covering materials, etc... It has good air permeability and light permeability and can maintain the appropriate temperature and humidity for crops.


Hydrophilic Nonwoven Fabric Examples.

It is an environmentally friendly textile fabric, with strong liquid adsorption, harmless to the human body, convenient, and practical. According to the different production processes. Hydrophilic nonwoven can be divided into 8 kinds.

1. Pulp airflow into a network of hydrophilic nonwoven fabric

Also known as dust-free paper, dry paper is a hydrophilic nonwoven fabric. It is the use of airflow into the network technology to open the wood pulp fiber board into a single fiber state. And then use the airflow method to make fiber agglomeration in the formation of a network curtain, fiber network, and then reinforced into cloth.

2. Wet hydrophilic nonwoven fabric

It is to loosen the fiber material in the water medium into a single fiber. At the same time make different fiber materials are mixed to make fiber suspension pulp. And the suspension pulp is transported to the web formation mechanism, and the fiber is formed into a web in the wet state and then reinforced into cloth.

3. Spunbond hydrophilic nonwoven fabric

After the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a web, and the fiber web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make the fiber web into a hydrophilic nonwoven.

4. Spunlace hydrophilic nonwoven

High-pressure micro-fine water is sprayed onto one or more layers of fiber webs to make the fibers entwine with each other. Finally, the fiber webs can be reinforced and have a certain strength.

5. Heat-bonded hydrophilic nonwoven fabric

It refers to adding fibrous or powdered hot melt bonding reinforcing material to the fiber web, which is then heated and melted, and cooled to reinforce the cloth.

6. Meltblown hydrophilic nonwoven fabric

The process: polymer feeding - melt extrusion - fiber formation - fiber cooling - into a network - reinforced into cloth.

7. Acupuncture hydrophilic nonwoven fabric

Needle-punched hydrophilic nonwoven is a kind of dry hydrophilic nonwoven fabric. The needle-punched hydrophilic nonwoven fabric uses the piercing effect of needles to reinforce the fluffy fiber network into cloth.

8. Sewn hydrophilic nonwoven fabric

A kind of dry hydrophilic nonwoven fabric. Sewn knitting method is to use the warp knitting coil structure to reinforce the fiber network, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.), or their combination to make hydrophilic nonwoven fabric.


What is hydrophilic and hydrophobic fabric?
