Abstract (en)
[origin: EP3048197A1] Disclosed are non-woven gauze product and a method and system for manufacturing the same. The spunlace device includes a second spunlace machine having a shaping layer on the surface, the shaping layer is provided thereon with pointed projections having tapered tops disposed in a matrix arrangement, each pointed projection has a bottom of rectangular cross-section, the bottom size of each pointed projection is larger than the bottom distance between two adjacent pointed projections. A non-woven cloth having rectangular holes in an array layout is formed by water jetting the fiber-web at the second spunlace machine. The rectangular holes in an array layout are presented in a flat structure having warp and weft, and the dimension of each rectangular hole is larger than the line width of warp and weft. The structure and features of such non-woven cloth are similar to those of gauze, so the non-woven cloth can be a substitute for the current gauze. With this invention, a gauze-like non-woven cloth is achieved by utilizing the disclosed manufacturing process of spunlace non-woven cloth herein, and the corresponding manufacturing method has advantages of short production period and low cost, which reduces the cost of such non-woven gauze product.
