Abstract
The utility model discloses a one-time forming high strength regenerating leather, comprising at least a layer of regenerating leather material layer; the inside of the regenerating leather material layer is provided with at least more than a layer of reinforced layer which can be formed in the one-time with the regenerating leather material layer; the reinforced layer is positioned on the upper surface of the regenerating leather material layer, the lower surface of the regenerating leather material layer, or between two layers of the regenerating leather material layers. On the ground that when the pieces are formed in the one-time at the same time, the utility model is additionally provided with the reinforced layer with fiber, the reinforced layer without the fiber, the reinforced layer with fiber products, or the reinforced layer without the fiber products for improving the strength of the regenerating leather. The utility model fundamentally solves the basic problem of insufficient strength for the regenerating leather and can achieve the strength requirement for producing a double-personal sofa or a three-personal sofa. The utility model can conduct the research development for products such as the leather of a vehicle seat, the leather of the shoe, etc.
Description
Technical field
The utility model relates to a kind of regenerative leather, especially relates to a kind of one-time formed high strength regenerative leather.
Background technology
Existing regenerative leather is the corner onal that utilizes tannery, Leather Goods Factory, need, split dried, mill skin, spraying and these a series of operations of embossing through pulverizing, hacking, base, solarization (baking), by the base of making being carried out split, cut out needed many regenerative leathers with splitter.Because existing regenerative leather only utilizes broken the processing of corner skin flour of leather, the form that its internal fiber structure is a staple fibre exists, though by certain adhesive combination, the root problem that has still had undercapacity, limitation is arranged in the application, existing regenerative leather can only be applied to that length and width are generally the 0.8 meter * manufacturing of single dining chair below 0.8 meter in belt, case and bag and the furniture, can not be applied to double above sofa and other need the manufacturing of the leathercraft of certain intensity.
The utility model content
The purpose of this utility model is to provide a kind of high-intensity one-shot forming regenerative leather.
The purpose of this utility model can be implemented by following technical measures: comprise one deck regenerative leather raw material layer at least, be equipped with the above and one-time formed enhancement Layer of regenerative leather raw material layer of at least one layer in the regenerative leather raw material layer.
Enhancement Layer described in the utility model is between upper surface, lower surface or the regenerative leather raw material layer of regenerative leather layer.
Enhancement Layer described in the utility model is fiber or non-fiber or fiber/non-textile.
Because the utility model in the one-time formed while of film-making, adds the enhancement Layer of fiber or non-fiber or fiber/non-textile, thereby improves the intensity of regenerative leather, has fundamentally solved the root problem of regenerative leather undercapacity.Reach the production length and width and be the requirement of strength of 1.18 meters * two (three) person sofa leathers more than 1.68 meters, thereby can develop into the research and development of a series of products such as automotive seat leather, footwear leather, widened the market space of regenerative leather greatly.
Description of drawings
Fig. 1 is the generalized section of the utility model specific embodiment one;
Fig. 2 is the generalized section of the utility model specific embodiment two;
Fig. 3 is the generalized section of the utility model specific embodiment three.
The specific embodiment
Present embodiment one has enhancement Layer 2 at each place mat of upper and lower surface of regenerative leather raw material layer 1 as shown in Figure 1, and enhancement Layer is a terylene.Embodiment one makes by following operation successively:
(1) adopts pulverizer that raw-material onal is smashed, break into a certain size cornu cutaneum, be generally below 10 * 10 millimeters.
(2) adopt the high speed rotation of unhairing machine that cornu cutaneum is broken into lint shape fiber, by exhaust equipment lint is extracted out then.
(3) pour in the barrel shape container being fibrous lint behind the hacking, inject its moisture content of 3 times; Stirred 8 minutes by mixer, make lint absorb moisture content, with the adhesion of increase with adhesive; Add adhesive epoxy resin commonly used then, wet hair suede and adhesive are evenly adhered to by even stirring; Auxilliary pad one deck terylene is poured the regenerative leather raw material lint slurry that stirs into the wooden frame mould and is paved in wooden frame mould bottom, spreads one deck terylene again on the lint slurry, compacting 8 minutes on squeezer then, and making it one-shot forming is the regenerative leather sheet material.
(4) the wet sheet of making is by movable carriage, and the bamboo bar has dried in the air it, through sunshine or natural air drying or oven dry.
(5) leather surface is polished, it is even to make it thickness.
(6) spray required color to leather.
(7) embossing is combined closely coating and surface more, and presses various decorative pattern.
Through above seven operations, make present embodiment one regenerated bark leather finished product.
Embodiment two
As shown in Figure 2, present embodiment two comprises two-layer regenerative leather raw material layer 1, each place mat has enhancement Layer 2 between the upper surface of the lower surface of ground floor regenerative leather raw material layer, second layer regenerative leather raw material layer and two-layer regenerative leather raw material layer, the enhancement Layer that is positioned at upper and lower surface is a terylene, and the enhancement Layer between two-layer is a carbon fiber.
The manufacturing process of present embodiment two and the foregoing description one are basic identical, and difference is the film-making operation.The detailed process of present embodiment two film-making operations is:
Pour in the barrel shape container being fibrous lint behind the hacking, inject its moisture content of 5 times; Stirred 10 minutes by mixer, make lint absorb moisture content, with the adhesion of increase with adhesive; Add adhesive epoxy resin commonly used then, wet hair suede and adhesive are evenly adhered to by even stirring; At wooden frame mould bottom auxilliary pad terylene, pouring the regenerative leather raw material lint slurry that stirs into the wooden frame mould paves, place mat carbon fiber on ground floor lint slurry again, pouring the regenerative leather raw material lint slurry that stirs on carbon fiber into paves, place mat terylene on second layer lint slurry again, then the wooden frame mould is placed on the squeezer compacting 10 minutes, and made it one-shot forming regenerative leather sheet material; Take out the wooden frame mould from squeezer, sheet material stops in mould after 10 minutes and takes out.
Embodiment three
As shown in Figure 3, present embodiment three comprises three layers of regenerative leather raw material layer 1, each place mat has enhancement Layer 2 between the upper surface of the lower surface of ground floor regenerative leather raw material layer, the 3rd layer of regenerative leather raw material layer and three layers of regenerative leather raw material layer, the enhancement Layer that is positioned at upper and lower surface is a terylene, and the enhancement Layer between layer is a carbon fiber.The manufacturing process of present embodiment three and the foregoing description two are basic identical, and difference is in the number of plies of enhancement Layer and the laying of regenerative leather raw material layer.
Claims (3)
