The modelling of nonwoven fabric manufacturing uses fibres or filaments laid down, without interlacing, in a web and bonded together mechanically (spun-bonding), (melt-blowing), or both. The resulting fabric, after bonding, typically produces a flexible and porous structure. These find use mostly in industrial and disposable applications.
The present research aims to study the mechanical and geometrical properties of polypropylene nonwoven fabric modelling and illustrate the effect of the parameters of the fabric construction technique and fabric orientation (MD-CD) in tensile and elongation behaviour. Through production, six samples with different weights as 13, 30, and 60 g/m2.
The samples under investigation are two types of nonwoven fabrics consisting of two and three-layered polypropylene webs produced by the carding process (spun-bonding) and (melt-blowing). The outer layer's web consists of (spunbond/spunbond), and the inner layer is melt-blow. The results of statistical analysis for correlation coefficients show that the parameters of the fabric construction technique of polypropylene nonwoven fabric have a strong correlation that affects the functional performance of multi-layer nonwovens in addition to various combinations of the two approaches for different technical textile applications.
Porosity is important in nonwoven fabrics like air filters, masks, and geotextiles. Pore size and distribution affect efficiency in air filters and mask performance. Geotextiles rely on pore structure for separation, filtration, drainage, and reinforcement in civil engineering.
