Wood pulp polyester and wood pulp PP (polypropylene) are two of the most common materials used in nonwovens, which are commonly used in a wide range of industries. Although both materials may seem similar, there are distinct differences between them.
Firstly, wood pulp polyester is made from polyester fibers and wood pulp, which are mixed together in a process called airlaid. This method allows for the fibers to be meshed together without the use of any binders or chemicals. This makes wood pulp polyester nonwovens more environmentally friendly, as there are fewer chemicals used in the manufacturing process.
On the other hand, wood pulp PP is made from polypropylene fibers and wood pulp, which are mixed together and then spun into a web using a process called spunbonding. This process creates a nonwoven fabric that is durable and has excellent resistance to water and other liquids.
In terms of their properties, wood pulp polyester nonwovens are often used in applications where a high degree of absorbency is required. This makes them ideal for use in products like hygiene products, such as wipes and diapers. They are also used in the medical industry for things like surgical gowns and face masks.
Meanwhile, wood pulp PP nonwovens are often used in applications where durability and resistance to water and other liquids is required. They are commonly used in products like geotextiles, roofing materials, and automotive interiors.
In summary, both wood pulp polyester and wood pulp PP nonwovens have their own unique properties and uses. While wood pulp polyester is more absorbent, wood pulp PP is more durable and resistant to liquids. By understanding these differences, manufacturers can choose the appropriate nonwoven material for their specific needs.
