For Tabby Woodpulp Spunlace Nonwoven, will the fabric density affect its tensile properties?

Fabric density refers to the number of yarns or fibers in a fabric per unit area, usually described as the number of yarns or fibers per square inch.

For Tabby Woodpulp Spunlace Nonwoven, fabric density can affect their tensile properties. Among nonwovens of the same material, the higher the density, the tighter the interlacing of the fibers, and thus the better the tensile properties of the nonwoven.

High density can increase the contact area between fibers.In the process of fabric manufacturing, fibers are interlaced by methods such as water needle punching to form the structure of nonwovens. When the fabric density increases, the number of fibers entering the fabric also increases accordingly, which will lead to an increase in the contact area between the fibers. More fibers interlaced with each other can form a tighter structure, thereby improving the strength and tensile properties of the nonwoven.

High density can make the fiber interlacing tighter.In the process of nonwoven fabric manufacturing, fibers are interlaced by methods such as water needle punching to form a fiber network structure. When the fabric density increases, the fibers in the fabric are more tightly interlaced, making the structure of the nonwoven fabric more stable. In contrast, in low-density nonwovens, the fibers are loosely interlaced, the structure is not tight enough, and it is easy to break or deform.

The increase in fabric density can increase the contact area between fibers and improve the tightness of fiber interlacing, thereby making the tensile properties of nonwovens better.

Therefore, in the manufacturing of plain wood pulp spunlace nonwovens, the fabric density can be controlled to achieve the desired tensile properties.
