How does the type of fiber raw material used in Spunlace Nonwoven Fabric affect its hygroscopicity and breathability?

Spunlace Nonwoven Fabric, that is, spunlace nonwoven fabric, its hygroscopicity and breathability are significantly affected by the type of fiber raw materials used. The following is a specific analysis:
Hygroscopicity:
Natural fibers: such as cotton, linen, silk, etc., have good hygroscopic properties because they contain hydrophilic groups. They can absorb and retain a large amount of moisture, allowing spunlace non-woven fabrics to remain dry in humid environments.
Synthetic fibers: such as polyester, nylon, etc., usually have poor hygroscopicity. These fibers do not easily absorb moisture, which may cause spunlaced nonwovens to feel sticky in humid environments.
Breathability:
Fiber thickness and length: Thicker and longer fibers create a looser fiber web, which facilitates air circulation and thus improves breathability.
Fiber arrangement and structure: The larger the gaps between fibers, the better the air circulation and the higher the breathability. The tight arrangement between fibers may hinder air circulation and reduce breathability.
In addition, the mixed use of different fiber raw materials can also adjust the hygroscopicity and breathability of spunlace non-woven fabrics to a certain extent. For example, mixing natural fibers and synthetic fibers can improve the durability and stability of spunlace non-woven fabrics while maintaining a certain level of hygroscopicity.
In summary, the type of fiber raw materials used in Spunlace Nonwoven Fabric has a significant impact on its hygroscopicity and breathability. When selecting fiber raw materials, comprehensive considerations need to be made based on the specific needs and uses of the product to achieve the best hygroscopic and breathable effects.
