Embodiment 1

[0022] This embodiment provides a method for preparing a fiber mat, comprising the following steps:

[0023] Firstly, each fiber bundle in the raw material is opened by using a fiber opener to obtain raw material fibers after opening. The raw material fiber used is an elastomer fiber, and the elastomer fiber is a three-dimensional crimped hollow fiber with a melting point of about 100°C.

[0024] The second step is to use a fiber carding machine to card the opened fibers to eliminate entanglement.

[0025] The third step is to use a web laying machine to spread the carded fibers evenly. After being carded into a uniform fiber web by a fiber carding machine, a continuous fiber mesh structure with multiple layers is formed by superimposing the inclined plane of the web and the action of negative pressure air, and is continuously output.

[0026] The fourth step is needle punching. The multi-layer fiber web is transported to the needle punching machine. The needle punching incl...

Embodiment 2

[0031] The main method and steps of embodiment 2 are similar to embodiment 1, and the difference is that the elastomer fiber used is the elk fiber (a kind of polyester buffer fiber with a melting point of about 150 ℃, which differs from ordinary fiber buffer materials in that its fiber arranged vertically). The needling depth is 15mm, the speed is 7.5m / min, and the needling density is 480 pricks / cm 2 . During hot pressing, the heating temperature is 220° C., the wind speed is 60 m / s, and the fiber mat is pressed to a thickness of 6 cm.

Embodiment 3

[0033] The main method and steps of Example 3 are similar to Example 1, except that the elastomer fiber used is polyetherester fiber (PP fiber) with a melting point of about 120°C. The needling depth is 12mm, the speed is 6.5m / min, and the needling density is 350 pricks / cm 2 . During hot pressing, the heating temperature is 150° C., the wind speed is 35 m / s, and the fiber mat is pressed to a thickness of 10 cm.

Abstract

The invention discloses a preparing method of a fiber mat. With elastomer fiber as the raw material, unit fiber layers with upper tension surfaces, lower tension surfaces and middle layers are formedthrough the steps of opening, carding, lapping, needling and the like, the overlapped unit fiber layers are hot-pressed, and finally the finished fiber mat of a multi-layer tension surface structure is prepared. The fiber mat prepared through the method has the multi-layer tension surface structure, the pressure exerted on the fiber mat can be buffered by multiple stages, the anti-collapsing performance is greatly improved, the light weight of the fiber mat is ensured, no glue is used in the production process, and no harm is caused to a human body.

Description

technical field [0001] The invention belongs to the technical field of fiber mats, in particular to a method for preparing a fiber mat and a fiber mat prepared therefrom. Background technique [0002] Because of its high comfort, cushions have become an indispensable household item in people's homes, and are widely used as mattresses, seat cushions, etc. Cushions generally include polyurethane sponge pads, coconut palm pads, and spring pads. However, most of the existing polyurethane sponge pad raw materials are petroleum by-products such as TDI and MDI, which are toxic in themselves, and production personnel are prone to disease after long-term contact, and the product has poor air permeability and poor user experience; it needs to be used in the manufacturing process of coconut palm pad If a large amount of glue is used for bonding, the formaldehyde content will seriously exceed the standard, and inhalation will cause harm to the human body; spring mattresses have problem...
