Fiber

The fibers used in medical non-woven fabrics(Medical SMS Nonwovens Wholesale) can be divided into natural and synthetic categories. The natural fibers used are wood pulp, cotton and rayon. Wood pulp is used because of its obvious absorbency, large volume and low cost. Cotton and rayon are better used directly on the wound. They have good absorbency and can be made into high-quality non-woven fabrics(Waterproof Nonwoven Fabric Manufacturer).

The reasons why natural fibers make high-quality medical non-woven fabrics(China SMS Non Woven Fabric Factory) are:

1. They highly absorb exudate and blood

2. Excellent breathability

3. Good aesthetic characteristics

4. Easy to clean and can be disinfected

5. Excellent dimensional stability and high operating temperature? 175 degrees Celsius

6. Biodegradable

7. Excellent drape and compliance

8. Good heat resistance

9. Excellent water retention capacity

10. Non-allergenic and non-irritating fiber

The most commonly used synthetic fiber in this application is: polypropylene, which has excellent rheological properties, needs hydrophobicity in some systems that require barrier properties, low cost, and is widely used for thermal bonding and increased functionality. Split fiber, and high-strength polyester, mechanical properties and easy sterilization are essential. Synthetic fiber also considers the product's strength, solvent resistance, static dissipation and many other desirable properties.

Properties of synthetic fibers required in many applications:

1. Hydrophobicity: can be used as a barrier fabric

2. Easy to process

3. Cost-effective

4. High strength, low density, better performance

5. Easy to handle, no danger
