Description

Technical Field

[0001] The utility model relates to the technical field of composite structures of uppers, in particular to a breathable paper pulp fiber imitation leather fabric. Background Art

[0002] Among the existing leather products, especially some leather products, the surface layer is generally made of animal leather. With the current environmental protection and changes in consumption concepts, such products can no longer adapt to the current consumer market. Therefore, PU leather and PVC leather imitation leather materials have gradually appeared on the market as shoe uppers. Although these materials have the characteristics of wear resistance, folding resistance, and waterproofness, they have poor air permeability, which causes users to feel stuffy, sweaty, and uncomfortable when wearing them for a long time.

[0003] Secondly, the surface of kraft paper has obvious texture effect, especially the existing semi-fiber kraft paper is a kind of kraft paper between short-fiber kraft paper and long-fiber kraft paper. This kraft paper has both the thickness and breathability of short-fiber kraft paper and the softness and fineness of long-fiber kraft paper. It is often used in the production of bags, leather goods, handicrafts, etc., and can also be used to make stationery, gift boxes and other daily necessities. It has good breathability, but its support is poor. If it is used as a shoe upper material, it is prone to quality problems such as collapse and deformation.

[0004] Therefore, if imitation leather materials such as kraft paper can be used as the upper and additionally designed to give it better support, it will undoubtedly achieve the advantages of environmental protection, durability, and breathability. Utility Model Content

[0016] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0017] See attached Figure 1-2 As shown, in the present embodiment, a breathable pulp fiber imitation leather fabric comprises an imitation leather surface layer 1, an inner lining layer 3 and a woven support mesh 2, wherein, taking footwear products as an example, the woven support mesh 2 needs to be prefabricated to form a shoe upper shape, specifically, the woven support mesh 2 is woven into a mesh shape by preset support wires, the support wires are a structure in which a main body is made of metal wires and a periphery is made of yarns twisted in a twisted shape, a needle bed warp knitting machine (a common device, which will not be described here) is used to weave the support wires to outline the shoe upper shape, and the rigidity and toughness of the metal wires are utilized to make the woven support mesh 2 have stronger pressure resistance and deformation resistance, and at the same time, the yarn is wrapped around the periphery of the metal wires to make the woven support mesh 2 lighter.

[0018] In the present embodiment, the imitation leather surface layer 1 is formed by directly wrapping pulp fibers around the outer periphery of the woven support net 2. Specifically, logs are used as raw materials, and through processes such as cooking, bleaching, screening, pulping, gluing, deslagging, netting, pressing, and drying, the pulp fibers are formed around the surface of the woven support net 2 to form the imitation leather surface layer 1, so that the woven support net 2 is wrapped inside the imitation leather surface layer 1. At this time, the woven support net 2 serves as a carrier of pulp fibers, thereby solving the shortcomings of the imitation leather surface layer 1 made of pulp fibers, such as easy deformation and poor support. It not only retains the characteristics of the imitation leather surface layer 1 being porous and breathable, bursting strength, and waterproof performance, but also has the characteristics of good support.

[0019] In this embodiment, the lining layer 3 is made of a porous non-woven fabric, and the lining layer 3 and the woven support net 2 covered with the imitation leather surface layer 1 are pressed together by point-to-point pressing, so that the lining layer 3 is partially sunken into the imitation leather surface layer 1 and the woven support net 2 are point-compounded, that is, the lining layer 3 corresponds to the inner surface of the imitation leather surface layer 1, and the lining layer 3, the imitation leather surface layer 1 and the woven support net 2 are compounded together by point-to-point pressing, without the need for traditional glue compounding, thereby ensuring that the compounded lining layer 3, the imitation leather surface layer 1 and the woven support net 2 are softer, more breathable and more environmentally friendly.

[0020] Specifically, the above-mentioned point-to-point pressing method can be composed of a pair of press-fitted pressing plates as shown in the accompanying drawings, wherein a plurality of composite points are protruded from the end faces of the pressing plates, and the point-to-point pressing of the lining layer 3, the imitation leather surface layer 1 and the woven support mesh 2 is completed by pressing the two pressing plates against each other to press the relatively aligned composite points.

[0021] In this embodiment, the design of the breathable pulp fiber imitation leather upper not only focuses on the appearance and touch of the upper, but also focuses on the functionality and durability of the upper. The design features and advantages of this upper will be further explained in detail below.

[0022] First, the braided support net 2, as the core structure of the upper, adopts a twisted structure combining metal wire and yarn, which gives the upper strong resistance to compression and deformation. The rigidity and toughness of the metal wire ensure the firmness of the upper, while the outer layer of yarn coating makes the entire braided support net 2 light while maintaining strength. This design allows the upper to maintain its shape while providing sufficient support, thereby solving the problem that the imitation leather surface layer 1 made of pulp fiber is easy to deform and has poor support.

[0023] Secondly, the imitation leather surface layer 1 is directly wrapped around the outer periphery of the woven support net 2, and is made of pulp fiber through a series of processes. The selection of this pulp fiber material makes the upper porous and breathable, while maintaining burst strength and waterproof performance. The woven support net 2 serves as the supporting skeleton of the imitation leather surface layer 1, so that the upper has good support while maintaining softness and delicate touch.

[0024] Thirdly, the inner lining layer 3 is made of porous non-woven fabric and is compounded with the woven support net 2 and the imitation leather surface layer 1 by point-to-point lamination. This compounding method avoids the disadvantages of traditional glue compounding, making the upper softer, more breathable, and more environmentally friendly. The point-to-point lamination method forms a firm connection between the inner lining layer 3, the woven support net 2 and the imitation leather surface layer 1, and the gap between the lamination points 4 also ensures the breathability and waterproof performance of the upper.

[0025] In the design, the thickness of the woven support mesh 2 and the setting of the pressing points 4 between the lining layer 3 and the woven support mesh 2 are also specially considered. The thickness of the woven support mesh 2 is not more than 1 / 3 of the thickness of the imitation leather surface layer 1, which ensures that the overall thickness of the upper is moderate, and is neither too thick to affect the wearing comfort nor too thin to affect the support of the upper. The gap between any two adjacent pressing points 4 between the lining layer 3 and the woven support mesh 2 is not less than 1-2mm, which avoids the overly dense pressing points 4 affecting the rigidity of the woven support mesh 2, and also ensures the air permeability and waterproof performance of the upper. The diameter of the pressing point 4 is not more than 0.3mm, which not only ensures the pressing effect, but also avoids the pressing point 4 being too large to affect the dustproof and waterproof performance of the upper.

[0026] Finally, the pulp fiber of the imitation leather surface layer 1 is made of semi-fiber material. This material between short fiber and long fiber makes the imitation leather surface layer 1 have both the thickness and breathability of kraft paper made of short fiber and the softness and fineness of kraft paper made of long fiber. This material selection makes the upper have excellent comfort and touch while maintaining strength and durability.

[0027] In summary, the breathable pulp fiber imitation leather upper design in this embodiment, through the ingenious combination of the woven support net 2, the imitation leather surface layer 1 and the lining layer 3, as well as the special process and material selection, realizes that the upper has excellent breathability and comfort while maintaining strength and durability. This design not only meets people's needs for the appearance and touch of the upper, but also fully considers the functionality and environmental protection of the upper.
