Description
Technical Field
The invention relates to a base cloth leveling method based on an animal leather fiber bundle winding fabric layer.
Background
Leather is a product commonly used in daily life, and "leather" refers to a product made of animal genuine leather, and with the development of industry, many substitute leathers have been developed, which are generally made of cloth made of chemical fibers or natural fibers as a substrate, and then a product similar to genuine leather in appearance is made by coating or pasting PU, PVC or other resin materials on one side of the above substrate, and such products are called: artificial leather, synthetic leather, PU leather, recycled leather, and the like.
The leather is made up by using the skin peeled from animal body and making it undergo the processes of a series of physical and chemical treatments. It removes almost all non-fibrous material and maintains the original braided state and structure of collagen fiber bundle.
The leather is divided into two layers in layer: the particle surface layer and the reticular layer are different in thickness, compactness and weaving form, the collagen fiber bundles in the particle surface layer and the reticular layer are fine, the diameter of the collagen fiber bundles on the surface of the particle surface layer close to the reticular layer is generally below ten microns, the collagen fiber bundles on the surface of the particle surface layer close to the epidermal layer are finer, the woven feet of the collagen fiber bundles on the surface of the particle surface layer are smaller, the woven feet of the collagen fiber bundles are gradually parallel to the surface, and the fiber weaving is tighter. The collagen fiber bundles of the reticular layer are thick and large and are naturally and tightly woven into a criss-cross three-dimensional reticular shape, so the reticular layer is called as the reticular layer. In the reticular layer, the elastic fiber and fat cells are few, and the reticular layer does not contain tissues such as fat glands, sweat glands, erector pili muscles, hair follicles and the like, so the fiber weaving continuity is good, the fiber is firm, the strength is high, and the reticular layer is the main part of the dermatome. The main part of the leather is collagen fiber bundle, and the collagen fiber bundle is always favored by consumers because of good performances of deodorization, ventilation and the like.
Although leather has many good properties, the resources of leather are limited, and therefore, other leather-like reconstituted leathers are now being developed.
For example, a currently available regenerated leather includes a collagen fiber layer and a leather surface layer, the collagen fiber layer is formed by leather through crushing to form leather short fibers, then the leather short fibers are bonded to a sheet material through an adhesive, and finally the leather surface layer is attached to one side of the sheet material. According to the regenerated leather with the structure, the leather short fibers are arranged in the sheet material and are connected through the adhesive, so that the regenerated leather is poor in tear resistance and not soft enough, and the regenerated leather has some performances of leather and also has the performance of glue, so that the regenerated leather is not breathable and environment-friendly, and the application range of the regenerated leather is influenced.
The base cloth for making leather is made by directly forming collagen fiber bundles into a base cloth through web forming and spunlacing, and the collagen fiber bundles are short and have a pure non-woven structure, so that the collagen fiber bundles are easy to slip, the physical properties such as tear resistance, bursting resistance and the like are insufficient, and the single use of the base cloth is influenced.
In addition, there is a collagen fiber bundle base fabric, which has a structure in which collagen fiber bundles are wound around a fabric layer, and the collagen fiber bundles, branches thereof, and the fabric layer are wound with each other to form a three-dimensional net structure.
Disclosure of Invention

In order to achieve the purpose, the base cloth leveling method based on the animal leather fiber bundle winding fabric layer comprises the following steps:
step (1): winding animal leather fiber bundles with multi-stage branches on a fabric layer to form a primary base fabric;
step (2): conveying the primary base cloth through a conveying roller, outputting the primary base cloth through a grabbing roller assembly and a negative pressure device, wherein one side of the primary base cloth, which is provided with animal leather fiber bundles, faces the grabbing roller assembly, the rotating grabbing roller assembly grabs loose animal leather fiber bundles on the primary base cloth through card clothing, the primary base cloth grabbed by the grabbing roller assembly is adsorbed by the negative pressure device, and in the process that the primary base cloth passes through the negative pressure device, the thin area of the primary base cloth is adsorbed by the negative pressure device and comprises the animal leather fiber bundles grabbed by the grabbing roller assembly;
and (3): and (3) carrying out water jet and/or needle punching on the primary base cloth treated in the step (2) to enable the animal leather fiber bundles and the branches thereof to be mutually interpenetrated and wound, and further forming the base cloth with a three-dimensional net structure by the animal leather fiber bundles, the branches thereof and the textile layer formed by the yarns.
The method comprises the steps that animal leather fiber bundles which are loosely or not tangled with a fabric layer and animal leather fiber bundles which are more tangled in partial areas of the fabric layer are grabbed through a grabbing roller group, when a grabbed primary base fabric is conveyed to a negative pressure adsorption device, the negative pressure adsorption device adsorbs the animal leather fiber bundles to a thin fabric layer area of the animal leather fiber bundles on the fabric layer under the adsorption action of the negative pressure adsorption device, so that the animal leather fiber bundles on the fabric layer are uniform, and then the uniformity of the whole base fabric is good through subsequent spunlacing and/or needling.
Further, the negative pressure device is supplemented with animal leather fiber bundles except the animal leather fibers grabbed by the grabbing rollers. So as to make up for the technical problem that the animal leather fiber bundles grabbed by the grabbing rollers are insufficient.
Further, textile fibers other than animal leather fibers are mixed in the step (1).
Further, step (2 a) is carried out after step (2) and before step (3), and step (2 a) is to lay animal leather fiber bundles on one side of the exposed fabric layer so as to enable two sides of the fabric layer to be respectively provided with animal leather fiber layers. Therefore, on one hand, the fabric layer is prevented from being exposed, on the other hand, the concave-convex parts of the fabric layer are covered by the laying of the animal leather fiber bundles, so that the surface of the base fabric is good in flatness, and the animal leather fiber bundles are fine in greasy feeling, good in antibacterial performance and good in flame retardant performance, so that the base fabric is better in performance and texture.
Furthermore, the grabbing roller group is a grabbing roller, and the structure is simple.
Furthermore, the grabbing roller group comprises a cylinder, a transfer roller, a stripping roller and a working roller; the primary base cloth is provided with one surface of the animal leather fiber bundle and faces the cylinder, the transfer roller is arranged on one side of the cylinder, the stripping roller is positioned on the outer circumference of the cylinder, and the working roller is positioned on the outer circumference of the cylinder and positioned on the right side of the stripping roller in the rotation direction of the cylinder. When the device works, the cylinder grabs loose animal leather fiber bundles from the primary base cloth, and opens and combs the animal leather fiber bundles through the stripping roller and the working roller, so that the animal leather fiber bundles are looser and have more branches, and then the animal leather fiber bundles are transferred to the transfer roller, and the animal leather fiber bundles on the transfer roller are adsorbed and used by the negative pressure adsorption device.
Furthermore, a bushing is arranged below the cylinder and the transfer roller, and gaps are respectively arranged between the bushing and the cylinder and between the bushing and the transfer roller. Therefore, the grabbed animal leather fiber bundles can be reliably transferred to the transfer roller.
