What Is Spinnlace Nonwoven?

Unlike spunbond and SMS nonwovens, which are produced through thermal or meltblown processes, spunlace is made by bonding fibers into the fabric by jets of high-pressure water. This water-based process is also known as hydroentangled bonding or jet entanglement, and it gives the resulting fabric physical properties that are similar to those of woven textiles. This includes softness, high bulk, drapability, flexibility and strength and depending on the fibers used, aesthetics that mimic traditional woven cloth. This makes it ideal for medical wet wipes, wet hair towels, facial tissues and even cosmetic rounds and masks.

Winner Medical has seen a growing demand for cotton spunlace due to its natural and skin-friendly qualities. For example, the company’s cotton spunlace meets the performance requirements of surgical gowns and other epidemic prevention products, which must be soft and breathable to allow people to work comfortably for long periods of time. Additionally, the cotton spunlace provides superior wet-strength and absorbency.

The production of cotton spunlace is an environmentally friendly and sustainable process that uses no chemical additives or chlorine bleach and has a lower bioburden than other nonwoven materials. This is due to the fact that it uses non-GMO cotton seeds from around the world, which are planted in natural plantations that are more than 200 kilometers away from industrial pollution. The raw cotton is then bonded into the spunlace fabric using water jets. This flexible entanglement preserves the original characteristics of the fiber and allows it to be easily formed into different shapes, which is then finished.

Spinnlace nonwoven fabrics can be produced from a wide range of raw materials. They can be manufactured with natural or synthetic fibers and are available in a variety of thicknesses and colors. They can be processed as plain, mesh or embossed fabrics. They are also available with or without anti-static treatment and in a variety of surface finishes.

The process of producing spunlace nonwoven is a relatively complex one, which involves a number of different steps. The raw material is open and mixed, mechanically meshed into a web, then blown into a high-pressure stream of water where it becomes hydroentangled. The resulting web can then be cooled, dried and spooled into rolls for use in medical, civil and industrial wipes.

In addition, the production of a spunlace nonwoven for wipes requires a special lapping process to ensure that the final product is able to withstand the high-speed wiping action. The two main options are straight and cross lapping. The former has good longitudinal and transverse strength, but it can be expensive to manufacture, while the latter has strong tensile and tearing properties. It is important to remember that the choice of lapping process is a key factor in the cost, quality and performance of the final product.
