Non-woven fabric manufacturing equipment

Abstract

The invention relates to non-woven fabric manufacturing equipment which comprises a first kneading roller and a second kneading roller which are oppositely arranged. A plurality of first kneading parts are convexly arranged on the roller surface of the first kneading roller; the extension directions of orthographic projections of the first kneading parts are kept inclined relative to the axis of the first kneading roller; the sections of the first kneading parts in the directions vertical to the extension directions of the first kneading parts has a trend of gradually shrinking from the roller surface of the first kneading roller to the direction far away from the roller surface; second kneading parts corresponding to the first kneading parts one by one are concavely arranged on the roller surface of the second kneading roller; and a kneading embossing unit is formed by each pair of corresponding first kneading part and second kneading part to carry out extrusion and drawing on a mechanical bonding non-woven fabric passing through a space between the first kneading roller and the second kneading roller and form high-density fiber regions and low-density fiber regions on the mechanical bonding non-woven fabric, so that a pattern prepared by the matching of the high-density fiber regions and the low-density fiber regions is formed on the mechanical bonding non-woven fabric.

Description

technical field [0001] The invention relates to a non-woven fabric manufacturing equipment. Background technique [0002] At present, the pattern appearance of spunlace non-woven fabrics is usually given by the method of spunlace jacquard. In this method, the fiber web is laid on the mesh curtain or mesh roller with special texture, and then the high-speed water jet is used to impact the fiber web, and at the same time cooperate with The ability of the screen curtain or the different areas of the screen roll to drain water so that the fibers in the fiber web become entangled. At the same time, under the impact of the water jet, the fibers in the fiber web will be displaced according to the pattern of the screen curtain or the screen roller, so that the number of fibers per unit area in the fiber web is different, so that the fiber web is formed with the screen curtain or the screen roller. The special texture corresponds to the pattern appearance with concave and convex tou...

AI Technical Summary

Problems solved by technology

[0003] However, this type of jacquard technology is complicated, the net curtain and mesh roll used for jacquard are expensive, and the cost of changing patterns is high, and this type of jacquard technology relies on spunlace equipment, which has narrow applicability

In the process of producing non-woven patterns, there is also a pattern appearance by hot-melt embossing non-woven fabrics, but this method can only deal with substrates containing hot-melt fibers, and usually accompanied by a decrease in the strength of non-woven fabrics, Weak water absorption capacity, hard hand feeling, etc.
