PP Nonwoven Fabric Machinery is used to manufacture non-woven fabrics. Generally there are three types: Composite Nonwoven Fabric Machine, Spunbond Nonwoven Fabric Machine and Melt Blown Nonwoven Fabric Line. These machines can produce nonwoven fabric of different GSM, width and color in roll form.
Nonwoven production of PP is an important and fast-growing industry. PP nonwovens are used for a variety of products including hygiene products, diapers, and adult incontinence pads. They are also used in medical applications such as surgical gowns, drapes and central supply room sterilisation wraps.
Several processes are employed to fabricate PP nonwovens, including air attenuation (melt-blown and spun bonding) methods and thermal treatment. The former is typically associated with fabrics having a high fibre diameter, and the latter with extremely fine fibres.
Melt blown and spun bonding are processes that involve the use of resins with very narrow molecular weight distributions. Fibers produced by these processes can be of very fine diameter, making them suitable for filter media.
To improve the moisture management capacity of PP nonwoven fabrics, VTES monomers silane were hydrolyzed in an ethanol/water system with MCC powder to yield reactive vinylsilanetriols groups [24]. This modification improved the water wicking height significantly compared to untreated PP nonwovens, as shown in Fig. 1.
Several factors affect the production of PP nonwovens, including the chemistry of the raw material, the type of masterbatch and the processing conditions. The optimum production conditions depend on the product, application and demand.
