Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
As shown in figure 1, the utility model relates to a preferable structure of a composite fabric for producing leatherware.
As shown in fig. 1, the composite fabric for producing leather products comprises a back cover base layer 10, a simulation skin layer 20, a particle layer 30 and a waterproof breathable film layer 40 which are tightly connected from bottom to top in sequence.
Wherein, the simulation cortex layer 20 is a non-woven fabric formed by interweaving collagen fibers and polyester superfine fibers through a needle punching method. The simulated skin layer of the utility model selects collagen fiber and terylene superfine fiber, and adopts needle-punching mechanical processing to form a fiber mesh-shaped base material, thereby being green and environment-friendly, and the mesh-shaped non-woven structure has better air permeability. And by compounding the polyester superfine fibers, the ageing resistance, tensile strength, tearing strength, elongation, flexibility and other properties of the simulation skin layer are improved, and the problems of low strength and low tearing strength of the single collagen fiber non-woven fabric are solved. Is more beneficial to the textile processing and popularization of the waste leather collagen fiber. In one implementation, the length of the polyester microfiber is not less than 20 mm.
On the other hand, the particle layer 30 is compounded on the upper surface of the simulation skin layer 20, the particle layer 30 is formed by thermally transferring polyurethane resin particles on a PET film, and the particle size of the polyurethane resin particles is 10-20 μm. The polyurethane resin particles have excellent chemical resistance and high and low temperature resistance, have better adhesive force to base materials which are difficult to bond, have better intermiscibility by using the resin particles, and the particles of small particles can be inserted into gaps of a net structure in a simulation leather layer, thereby avoiding increasing the thickness of leather and improving the composite strength of products.
On the other hand, the composition and structure of the real leather are simulated by the high gloss particle layer formed by the polyurethane particles and the simulation skin layer. The product is similar to natural leather, and has bright appearance, soft texture, wear resistance, folding resistance, acid and alkali resistance, etc. And the highlight particle layer is added, so that the leather surface has stereoscopic impression, and the leather has good touch, glossiness and simulation effect.
The upper surface and the lower surface of the composite fabric can be compounded with waterproof breathable film layers, and the upper layer and the lower layer are both provided with double waterproof layers, so that the material keeps good breathability and can achieve a waterproof function. The waterproof breathable film layer is achievable by those skilled in the art according to known materials and known processes.
In one implementation, the waterproof breathable membrane layer is made of a breathable hydrophobic expanded polytetrafluoroethylene material.
In a preferred implementation, the surface of the composite fabric is also subjected to antibacterial self-cleaning treatment. The surface of the photocatalyst self-cleaning coating is provided with a photocatalyst self-cleaning coating. The antibacterial self-cleaning layer is formed by coating the existing product on the waterproof breathable film layer. The utility model improves the self-cleaning capability of the artificial leather composite fabric and effectively reduces the problem of surface mildewing through the photocatalyst self-cleaning coating.
The back cover base layer 10 is made of spunlace fabric formed by intertwining collagen fibers and sea island fibers. The back cover base layer 10 is used for improving the mechanical property and the air permeability of the artificial leather composite fabric.
In one implementation, the length of the collagen fibers of the back cover base layer is 20-40 mm; the sea-island fiber of the back cover base layer is a terylene sea-island fiber with the length of 40-45 mm.
The back cover base layer is formed by mixing, opening and feeding, air-laying, spunlace reinforcing and drying and winding collagen fibers and sea-island fibers.
In the present invention, preferably, a super-amphiphobic coating is further disposed on the outer surface of the back cover base layer 10. The contact angle of the super-amphiphobic coating to oil and water is more than 150 degrees, the rolling angle is less than 10 degrees, and the tolerance temperature and the application range can be between-40 ℃ and 80 ℃. The super-amphiphobic coating can be directly applied to the existing product and directly and uniformly sprayed on the outer surface of the bottom sealing base layer, and the process is simple. Based on super-hydrophobic and super-oleophobic properties, the surface formed by the super-amphiphobic coating has certain self-cleaning advantages.
It should be noted that the composition between the functional layers of the composite fabric of the present invention is realized by those skilled in the art, such as by thermal compression, adhesion, etc., and will not be described herein too much.
