Non-woven fabric is a kind of non-woven fabric that is different from the traditional non-woven fabric, with various production processes, usually spunbond, melt-blown method, hot rolling method, and spunlace method, among which the non-woven fabric manufactured by spunlace method is called spunlace non-woven fabric.
First, the characteristics of spunlace non-woven fabrics
Spunlace non-woven fabric is a fabric obtained by spraying high-pressure fine water flow onto one or more layers of fiber web, so that the fibers are entangled with each other, so that the fiber web can be strengthened and has a certain strength.
Spunlace non-woven fabrics have a variety of raw materials, natural fibers and chemical fibers can be made into spunlace non-woven fabrics by spunlace method, and do not affect the original characteristics of the fiber, do not damage the fiber. Compared with other non-woven fabrics, spunlace non-woven fabrics are closer to traditional weavings in appearance, soft and fluffy to the touch, with high strength, high moisture absorption, high air permeability, and low fluffing, and are widely used in the manufacture of medical bandaging materials, advanced wipes, wound dressings, etc.
In addition, spunlace non-woven fabrics can also be used to produce more skin-friendly and comfortable medical surgical gowns, medical masks, etc., due to their soft and breathable properties similar to traditional fabrics, but they need to be finished with waterproof function of hydrostatic pressure.
2. Waterproof finishing of spunlace non-woven fabrics
In this paper, Texnology®FCB016 developed by Guangzhou Lianzhuang Technology Co., Ltd. is an example of a non-flammable water-based emulsion with no flash point, no volatile organic solvents, no irritating odor, and no effect on the original softness, breathability, high toughness and other characteristics of spunlace nonwovens.
Texnology®FCB016 is easily soluble in water, can be diluted with deionized water in a certain proportion, and then adhered to the surface of the spunlace non-woven fabric by spraying and other methods to cross-link to form a film, giving the spunlace non-woven fabric excellent waterproof function and improving its hydrostatic pressure resistance.
