Spunbond Nonwovens
Polymers are used to develop spunbond nonwovens. Polymer fibers are passed through an extruder, stretched into continuous filaments, and then spread out evenly and laid into a web. The melting and spinning process produces a web of fibers that are entangled with each other. The resulting web is treated chemically, thermally, or mechanically to form the final fabric.
Spunlace Nonwovens
This unique nonwoven fabric gets its name from its fantastic manufacturing process, which uses high-pressure water jets to entangle and bond multiple layers of fiber webs together. High pressure strengthens the yarn, but the resulting yarn is not as strong as other nonwovens. Fibers such as silk, polyester, nylon, bamboo fiber, wood pulp, viscose fiber, etc. are usually used to develop spunlace nonwoven for the manufacture of disposable surgical gowns, filters, masks, wipes, etc.
Hot-melt Nonwovens
The main bonding process for this nonwoven fabric is heating. The fiber web is bonded together with a binder and treated with high temperature. By heating, the binder in the fiber layer melts. After cooling, the fiber web is combined into a single nonwoven fabric.
Meltblown Nonwovens
A complex, systematic process is used to develop and manufacture melt-blown nonwovens. The molten polymer fibers are extruded through a die with hundreds of tiny holes. These tiny holes are the size of the final fibers. Hot air is blown through the fibers to cool them, and the fiber web is collected on a collecting screen. Here, the fibers are combined to form a nonwoven fabric.
Wetlaid Nonwovens
The fiber raw material is placed in an aqueous medium. It helps the fibers to unfold into individual fiber bundles. Different types of fiber raw materials are added to the suspended fiber mass to form a slurry. This slurry-like substance is processed to form a nonwoven fabric.
Stitch bonded Nonwovens
The strength of this entangled knitted loop structure nonwoven fabric comes from its number of layers, which enhances the structure of the final material and makes it strong. The individual layers include fiber webs, yarn layers, etc.
Hydrophilic Nonwovens
Hydrophilic nonwovens are used to make hygiene materials and other medical-grade or surgical materials. The material is soft to the touch and sensitive to the skin.
Properties of Nonwovens
Nonwovens are widely used in the modern world. Affordable prices are one of the reasons for the increase in the use of nonwovens. The biodegradable nature of nonwovens makes them an excellent alternative to plastics. Nonwovens are not suitable for making clothing due to durability issues. However, it is perfect for making disposable medical devices. Nonwovens are steadily replacing polyurethane foam. Bags and other supply materials can be made from nonwovens. These fabrics are waterproof and are an excellent choice for this use.
