Technical Field

[0001] The utility model relates to a non-woven fabric, in particular to a flocked non-woven fabric for automobile interior decoration. Background Art

[0002] Non-woven fabric is a new generation of environmental protection material, which has the characteristics of moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic, non-irritating, rich in colors, low in price, recyclable, etc. Non-woven fabric is widely used in automobile interior decoration. With the diversification and humanization of automobile models, for automobile interior decoration, in addition to paying attention to beauty, consumers also put forward higher requirements for its comfort and environmental protection. Most of the existing non-woven fabrics for automobile interior decoration adopt the way of multi-layer bonding to ensure its thickness to meet its elastic requirements. However, due to the large influence of the use environment of the automobile by the outside world, in a high-temperature environment, the bonded products are not only easy to produce harmful substances, but also delaminate and crack, thus affecting its service life. Summary of the Invention

[0003] Aiming at the technical problems that most of the existing non-woven fabrics for automobile interior decoration adopt the bonding method, resulting in the generation of harmful substances at high temperature, which is not conducive to environmental protection, and is easy to delaminate and crack, affecting its service life, the utility model provides a flocked non-woven fabric for automobile interior decoration that does not need to use adhesives, avoids the generation of harmful substances, and greatly improves the environmental protection and comfort.

[0004] To this end, the technical solution of the utility model is that a flocked non-woven fabric for automobile interior decoration is provided with a fiber base layer, a needled layer and a woven layer. The lower surface of the needled layer is needled and compounded on the upper surface of the fiber base layer. A layer of flocked surface is formed by needling on the upper surface of the needled layer. A woven layer is provided on the lower surface of the fiber base layer. The woven layer is woven inside the fiber base layer. Fixed lines are arranged crosswise on the woven layer, and the fixed lines are fixed on the fiber base layer.

[0005] Preferably, the thickness of the fiber base layer is 3-5mm.

[0006] Preferably, the thickness of the needled layer is 1-3mm.

[0007] Preferably, the woven layer extends 2-4mm out of the fiber base layer.

[0008] Preferably, the fiber base layer is made of recycled fiber raw materials.

[0009] The beneficial effects of the utility model are as follows:

[0010] (1) By setting the combined use of the needling layer and the twill layer, the elasticity of the non-woven fabric is improved. The needling layer is needled on the upper surface of the fiber base layer, which is firm and reliable, and no adhesives are used. Even at high temperatures, no harmful substances will be generated, and there will be no delamination or cracking. This not only improves the environmental protection performance but also extends the service life of the product.

[0011] (2) By setting the twill layer on the lower surface of the fiber base layer, it can play an anti-slip role, and the twill layer is woven into the fiber base layer, with reliable connection.

[0012] (3) By setting the fixing lines on the twill layer, the fixing lines are fixed on the fiber base layer, further ensuring the reliable connection between the twill layer and the fiber base layer. And appropriately compressing the twill layer through the fixing lines helps to improve the anti-slip effect.

[0013] (4) Through the reasonable setting of the thickness of the fiber base layer, the twill layer, and the needling layer, as well as the reasonable matching of the structures, without increasing the production cost, the elasticity and anti-slip performance of the product can be significantly improved, improving the comfort of users and extending the service life, which is beneficial to enhancing the market share of the product.

[0018] The following further describes the present utility model with reference to the embodiments.

[0019] As Figure 1-2 shown, a napped non-woven fabric for automotive interior is provided with a fiber base layer 2, a needling layer 1, and a twill layer 3. The lower surface of the needling layer 1 is needle-compounded on the upper surface of the fiber base layer 2, and a layer of napped surface is formed by needling on the upper surface of the needling layer 1. The lower surface of the fiber base layer 2 is provided with a twill layer 3, the twill layer 3 is woven inside the fiber base layer 2, and cross-arranged fixing lines 4 are provided on the twill layer 3, and the fixing lines 4 are fixed on the fiber base layer 2.

[0020] The thickness of the fiber base layer 2 is 3 - 5 mm, the thickness of the needling layer 1 is 1 - 3 mm, the twill layer 3 protrudes from the fiber base layer by 2 - 4 mm, and the fiber base layer 2 is made of recycled fiber raw materials, reducing the production cost.

[0021] By setting the combined use of the needling layer 1 and the twill layer 3, the elasticity of the non-woven fabric is improved. The needling layer 1 is needled on the upper surface of the fiber base layer 2, which is firm and reliable, and no adhesives are used. Even at high temperatures, no harmful substances will be produced, and there will be no delamination or cracking phenomenon. This not only improves the environmental performance but also extends the service life of the product. By setting the twill layer 3 on the lower surface of the fiber base layer 2, it can play an anti-slip role, and the twill layer 3 is woven into the fiber base layer 2, with reliable connection. By setting the fixing wire 4 on the twill layer 3, the fixing wire 4 is fixed on the fiber base layer 2, further ensuring the reliable connection between the twill layer 3 and the fiber base layer 2. And appropriately compressing the twill layer 3 through the fixing wire 4 helps to improve the anti-slip effect. Through the reasonable setting of the thicknesses of the fiber base layer 2, the twill layer 3, and the needling layer 1 and the reasonable combination of the structures, without increasing the production cost, the elasticity and anti-slip performance of the product can be significantly improved, the comfort of the user can be improved, the product life can be extended, which is beneficial to the improvement of the product market share.

[0022] The non-woven fabric with this structure can not only achieve a good anti-slip effect, but also has good elasticity and softness, and there is no need to use adhesives between the layers. It not only avoids the problems of glue opening and layer cracking, but also is more environmentally friendly, and can be widely used in automobile interiors.
