Description

Technical Field

[0001] The utility model relates to an environment-friendly moisture-absorbing and breathable protein leather fabric. Background Art

[0002] With the development of the concept of environmental protection, water-based PU leather, as a new type of environmentally friendly synthetic leather material, does not contain toxic organic solvents, the production process is pollution-free, and there is no emission of toxic and harmful waste gas and wastewater. It does not contain harmful chemical substances such as DMF, formaldehyde, and heavy metals, is healthy and environmentally friendly, harmless to the body, has environmental protection characteristics, and also has characteristics such as abrasion resistance, bending resistance, and ultraviolet resistance. It has gradually begun to be widely used in industries such as sofa fabrics. However, in terms of its functions, the gap with natural leather in terms of moisture absorption and breathability is still relatively obvious. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies existing in the prior art, and to provide an environment-friendly moisture-absorbing and breathable protein leather fabric with reasonable design, simple structure, environmental protection, and good moisture absorption and breathability.

[0004] The technical solution adopted by the utility model to solve the above problems is: an environment-friendly moisture-absorbing and breathable protein leather fabric, including a base layer, a glue layer, a middle foaming layer, and a surface layer. The base layer is formed by the overlapping of warp yarns and weft yarns to form a grid structure. The surface layer is made of water-based PU leather. The middle foaming layer is distributed with honeycomb-shaped fine micropores. Glue layers are coated on both the upper and lower surfaces of the middle foaming layer. The upper surface of the middle foaming layer is bonded to the surface layer, and the lower surface of the middle foaming layer is bonded to the base layer.

[0005] Preferably, the thickness of the surface layer is 0.03 - 0.05 mm.

[0006] Preferably, the thickness of the middle foaming layer is 0.15 - 0.2 mm.

[0007] Preferably, the thickness of the base layer is 0.2 - 0.3 mm.

[0008] Preferably, calcium sulfate is filled in the surface layer and the base layer.

[0009] The base layer of the utility model adopts a grid structure formed by the overlapping of warp yarns and weft yarns, which increases the air permeability and wear resistance. The surface layer is made of water-based PU leather, and the glue layer is made of water-based PU glue, which has the advantages of environmental protection, pollution-free, safety and reliability, etc. Calcium sulfate is filled in the surface layer and the base layer, so that the fabric has a moisture absorption effect. The middle foaming layer is distributed with honeycomb-shaped fine micropores, which increases the air permeability of the fabric. Brief Description of the Drawings

[0014] The present utility model will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0015] See Figures 1-3 , in this embodiment, the environmentally friendly moisture-absorbing and breathable protein leather fabric includes a base layer 1, a glue layer 2, a middle foaming layer 3, and a surface layer 4. The base layer 1 is formed by overlapping warp and weft yarns in a grid structure, and both the warp and weft yarns are made of polyester filaments, which increases the air permeability and wear resistance. The surface layer 2 is made of water-based PU leather, which has the advantages of environmental protection, pollution-free, safety and reliability, etc. The foaming structure of the middle foaming layer 3 is honeycomb-shaped and forms tiny pores 5, which can increase the air permeability of the fabric. Glue layers 2 are coated on both the upper and lower surfaces of the middle foaming layer 3. The upper surface of the middle foaming layer 3 is bonded to the surface layer 4, and the lower surface of the middle foaming layer 3 is bonded to the base layer 1. The glue layer 2 is made of water-based PU glue, which is environmental protection and pollution-free.

[0016] In this embodiment, the thickness of the surface layer 4 is 0.03 - 0.05 mm, and a water-based PU leather surface layer with an ultra-thin thickness is used to ensure the air permeability of the fabric finishing.

[0017] In this embodiment, the thickness of the middle foaming layer 3 is 0.15 - 0.2 mm.

[0018] In this embodiment, the thickness of the base layer 1 is 0.2 - 0.3 mm.

[0019] In this embodiment, calcium sulfate is filled in the surface layer 4 and the base layer 1.
