The Bi-Component Nonwoven Fabric

The Bi-component Nonwoven Fabric of the present invention is a polymeric material having two or more layers. These layers may be continuous or non-continuous. These materials feature a unique geometry because they do not have a straight, flat surface, like a filament fiber. Instead, they have a nonlinear geometry and irregular surface that provide the necessary anchoring properties for the bi-component polymeric macrofibers to adhere to a cement matrix.

These bi-component fibers are most commonly used to manufacture thermo-bonded nonwoven fabrics. They can also be produced into textured yarns by using special polymers or additives. The "Cantrese" yarn by DuPont in the 1960s appeared to be a bi-component nylon polymer. It was quickly followed by side-by-side hosiery yarns.

The composite nonwoven fabric in the present invention comprises a first nonwoven layer containing discrete point bonds. The second nonwoven layer supports the sorbent dust and is interwoven with the first and second nonwoven layers. The two layers are then stitched together along a lengthwise elongated line of stitches. This stitching gives the fabric its strength and stability. Once woven, the two layers may be napped or ribbed.

In this paper, we introduce a new technique to measure the mechanical properties of nonwoven fabrics. This technique is useful for testing different materials in the same process. X-ray microcomputer tomography and scanning electron microscopy data were used to estimate orientation distribution functions. These measures quantify the randomness and anisotropy of the material's microstructure. They also provide insight into the properties of the fibres used to make the material.

A bi-component nonwoven fabric can be manufactured in two different ways. One type is meltblown, and the other is called a bi-component nonwoven fabric. As a result, it is easier to work with and is much lighter than traditional nonwoven fabric. The benefits of this fabric are numerous. The Bi-component Nonwoven Fabric is a unique material that offers many applications. So, how does it differ from other fiber materials?

The Bi-component Nonwoven Fabric of the present invention comprises two polymers, one as an outer component, and the other as a fiber. The outer component is EVOH, a copolymer of 48 mol% ethylene and 52 mol% vinyl alcohol. The second component is a blend of polypropylene and PP-g-maleic anhydride. The weight ratio of PP/g-MAH is approximately 95/5 for INS fibers, and 80/20 for sheath/core fibers.
