SYSTEM AND METHOD FOR MULTIPLE SURFACE WATER JET NEEDLING
20180291541 · 2018-10-11 · ·

A water entanglement system having a first rotatable surface comprises a first water jet which may be configured to water-entangle a preform in situ. The water-entanglement system may comprise a second rotatable surface disposed proximate the first rotatable surface. The second rotatable surface may comprise a second water jet configured to water-entangle the preform in situ. The first rotatable surface may be oriented substantially parallel to the second rotatable surface.

Non-woven gauze and method and system for manufacturing the same
10045884 · 2018-08-14 · ·

A non-woven gauze product and a method and system for manufacturing same. The spunlace device includes a second spunlace machine having a shaping layer on the surface, the shaping layer is provided 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 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.

PLANT AND METHOD FOR CONNECTING A WEB OF FIBROUS MATERIAL TO A NONWOVEN OR CONSOLIDATING IT THEREWITH

A plant and a method for connecting a web of fibrous material to a nonwoven or consolidating it therewith includes a first circulating belt on which the web of fibrous material is laid, a device for introducing a nonwoven into the plant, and a further successive circulating belt on which the nonwoven is to be connected to or consolidated with the web of fibrous material. The web of fibrous material from the first circulating belt is first laid on the nonwoven and subsequently the fibrous material is transferred onto the successive belt together with the nonwoven for connection or consolidation by use of water jets.
