Description

Composite non-woven fabric jacquard device

Technical Field

The utility model belongs to non-woven fabrics manufacture equipment field, concretely relates to compound non-woven fabrics jacquard device.

Background

The existing nonwoven jacquard devices basically adopt the following 3 methods:

the method comprises the following steps: the fiber web is in a concave shape and a convex shape formed by the lines, the thickness and the weaving mode of the net threads of the spunlace net, and the fiber web is impacted by high-pressure water flow on the spunlace net to enable the fibers of the fiber web to slide and be stacked in the concave position to form a structural pattern which is the same as the structure of the net.

The method 2 comprises the following steps: the holes and the concave-convex patterns on the drum are adopted, so that the fibers of the fiber layer are accumulated in the holes and the concave parts under the action of the high-pressure water jet to form the pattern.

The method 3 comprises the following steps: the non-woven fabric is pressed by adopting concave-convex embossing rollers to form a concave-convex pattern.

However, the three methods have certain disadvantages in practical use:

the method comprises the following steps: the net weaving has certain limitation, complex patterns cannot be woven, the net weaving is complex, the net weaving of special patterns is difficult, the cost is high, and the net weaving is only suitable for regular and simple concave-convex patterns.

The method 2 comprises the following steps: the circular drums with various patterns can be made according to requirements by adopting circular drum jacquard, but some full-empty patterns are difficult to realize, and the manufacturing cost of the circular drums is very high.

The method 3 comprises the following steps: embossing by the embossing roller can only change the local concave-convex of the fiber layer, and if no thermal deformation fiber exists, the fiber layer is difficult to shape, and the pattern can hardly be seen after the fiber layer is wetted.

Therefore, how to weave a non-woven fabric needs to provide a simple and reliable composite non-woven fabric jacquard device.

In a preferred embodiment of the present invention, as shown in fig. 1, a composite nonwoven jacquard device is provided, the core component of which comprises two parts, namely a hydroentangling net 1 and a hydroentangling device 6.

As shown in fig. 2, the conventional spunlace 1 is a flat web with a large number of holes densely distributed therein, the composite nonwoven 5 is laid on the web surface of the web, and the water needles ejected from the spunlace device 6 can directly penetrate through the web body through the holes during the spunlace process, thereby performing spunlace entanglement on the nonwoven. However, in the present invention, the spunlace net 1 is improved to some extent. Referring to fig. 3, the spunlace 1 seals and seals part of the mesh holes with waterproof material, so that the water needles cannot penetrate the mesh holes. For convenience of description, the meshes of the spunlace net 1 blocked by the waterproof material are referred to as sealed holes 2, and the meshes not blocked by the waterproof material are referred to as water-permeable holes 3. The specific arrangement position of the sealing holes 2 on the mesh surface needs to be designed according to patterns needing jacquard, and the patterns are consistent with the patterns which are finally formed.

The waterproof material on the spunlace 1 can realize the plugging of meshes through coating and printing modes such as spraying, blade coating and the like, so that a waterproof pattern is formed on the net surface. The waterproof material can be selected according to actual needs, needs to have certain cohesiveness with the material of the spunlace net, and can be firmly fixed on the spunlace net 1. At the same time, the waterproof material should have sufficient strength so that it does not fall off under the impact of the squirt. The utility model discloses in, waterproof material can adopt waterproof bonding glue, recommends to be epoxy. Of course, other waterproof materials can be used as long as the corresponding functions can be realized. In addition, the spunlace mesh 1 of the present invention can be made of resin mesh or metal mesh.
