Embodiment 1

[0022] The general process flow of multi-color non-woven materials is: rough opening → fine opening → blending → carding → laying → consolidation.

[0023] Such as figure 1 As shown, in the cotton mixing process, two mixing baffles 2 are set in the mixing box 1, and the mixing box is divided into three independent parts, and each independent part is provided with a raw material inlet, and one of the raw material inlets is connected with the cotton mixing The feed openings of the boxes are connected, and two feeding baffles are arranged on the feeding curtain for partitioning, and the feeding baffles are connected with the baffles 2 of the mixing box. When the colored fiber B is mixed, it only falls into the middle part of the mixing box. After the colored fibers A and C are roughly opened and finely opened, they are manually put into the other two raw material inlets of the mixing box. The angle of the two baffles 2 in the center can be used to adjust the area occupied by A, ...

Abstract

The invention discloses a manufacturing method of a multilayer nonwoven material and manufacturing equipment thereof. In the method, in a cotton blending step, a single blending hopper is used; the inside of the blending hopper is separated into two or more independent parts; each independent part is used for blending one fiber raw material to form different fiber bundles; the different fiber bundles are respectively fed into the same feeding screen, enter the same carding machine and the same lapping machine in parallel, and form a multilayer fiber web; and the multilayer fiber web is consolidated into the multilayer nonwoven material. Compared with the current method and equipment for preparing the multilayer nonwoven material, the method and the equipment of the invention have the advantages that the process flow is not changed, the number of required equipment is reduced, and the production cost is reduced.

Description

technical field [0001] The present invention relates to the field of nonwoven materials, in particular to the field of multilayer nonwoven materials. Background technique [0002] With the improvement of living standards, the market penetration rate of decorative products such as non-woven fabrics for interior decoration and non-woven fabrics for outdoor decoration is getting higher and higher, and people's requirements for them are also getting higher and higher. In non-woven fabric products for decoration, non-woven fabrics with multiple color layers are usually used in the products, so as to achieve different colors on the inside and outside, front and back sides, and better integrate with the external environment. [0003] In the existing production process, two methods are generally used: parallel laying to form a web or cross-folding and laying a web and then superimposing a parallel carding web. The parallel laying method uses multiple carding machines and multiple w...
