Embodiment 1

[0058] The present embodiment provides a kind of preparation technology of fiber mat, such as figure 1 shown, including the following steps:

[0059] Laying and pressing several fiber balls 3 to form the first fiber web layer 1;

[0060] Drop several fiber balls 3 naturally to form the second fiber web layer 2;

[0061] At least one layer of the first fiber web layer 1 and at least one layer of the second fiber web layer 2 are stacked in the vertical direction to form a preset fiber mat in which the top layer and the bottom layer are the first fiber web layer 1;

[0062] Fix and connect two adjacent fiber mesh layers to form a fiber mat;

[0063] The fiber ball 3 is formed by the aforementioned mixed fibers, the mixed fibers include plant fibers and bicomponent fibers, and the bicomponent fibers include high melting point components and low melting point components.

[0064] In the preparation process of this fiber mat, the first fiber net layer 1 is formed by paving, so th...

Embodiment 2

[0087] This embodiment provides a preparation process of a fiber mat, the only difference from Example 1 is that the fiber ball layer is used instead of the fiber ball 3 in Example 1 to prepare the first fiber web layer 1 and the second fiber web layer 2 . That is, the fiber ball layer 3 in Example 1 is first formed into a fiber ball layer, then the fiber ball layer is laid to form the first fiber web layer 1 , and the fiber ball layer is naturally dropped to form the second fiber web layer 2 .

[0088] The fiber ball layer in this preparation process has a layered structure with uniform thickness, which is convenient for the natural drop of the fiber ball layer to form the second fiber web layer 2 with uniform thickness, and the first fiber web layer 1 with uniform thickness is formed by laying, which is also convenient for controlling the formation The thickness of the first fiber web layer 1 and the second fiber web layer 2, the stacking operation of the second fiber web la...

Embodiment 3

[0103] This embodiment provides a fiber mat, which is prepared by the preparation process provided in Embodiment 1. The fiber mat with this structure is prepared by adopting the preparation process provided in Example 1, so that the fiber mat has the desired hardness and high resilience.

Abstract

The invention discloses a fiber pad and a preparation process thereof. The preparation process includes steps: paving and pressing mixed fiber and / or a plurality of fiber balls / fiber ball layers to form a first fiber net layer; enabling the fiber balls / fiber ball layers to naturally fall down to form a second fiber net layer; stacking the first fiber net layer and the second fiber net layer along the vertical direction to form a pre-arranged fiber pad with the first fiber net layers on both the top layer and the bottom layer; connecting and fixing each two adjacent fiber net layers. The fiber pad is prepared by adopting the preparation process. Another fiber pad comprises at least two first fiber net layers and at least one second fiber net layer, elasticity of the second fiber net layers is greater than that of the first fiber net layers or elasticity of the second fiber net layer is less than that of the first fiber net layers, the second fiber net layers serve as elastic layers, the first fiber net layers serve as stress bearing layers, and each second fiber net layer comprises a netty structure formed by connecting and fixing each two adjacent fiber balls, so that the fiber pad meets requirements on needed hardness and is high in resilience.

Description

technical field [0001] The invention relates to the technical field of cushions, in particular to a preparation process of a fiber cushion and the fiber cushion. Background technique [0002] In the preparation process of fiber mats in the prior art, the fibers are usually opened first, and then the fibers after opening are laid by a web-laying machine to form a layer-by-layer network structure, and then the multi-layered fibers are glued together with glue. The fiber webs are bonded together to form a fiber mat. However, the multi-layer fiber webs are bonded together by glue. After a period of use, the bonding performance of the glue will decrease, resulting in the adhesion between the multi-layer fiber webs. not good. [0003] Chinese patent document CN103061041A discloses a preparation process of a fiber mat, which includes the following steps: first carding and mixing various fibers respectively; Puncture the fiber mat into a predetermined shape; blow hot air on the fi...
