Abstract
The present invention has the technological scheme of using regenerative leather produced through a drying process as the base for the synthetic leather. The making process of the synthetic leather includes producing base for the synthetic leather via drying process; soaking the base in polyurethane solution; milling to level, dissecting and surface decoration. The synthetic leather of the present invention has low cost and high performance.
Description
Affiliated technical field
The present invention relates to a kind of synthetic leather and manufacturing technique thereof.
Background technology
The structure of synthetic leather comprises base cloth and the top layer that sticks on the base cloth.The top layer is mainly played decoration and is made the outward appearance of hide fiber synthetic leather reach the effect of imitating natural leather.And the Main physical performance indications of synthetic leather are determined by its base cloth.Existing synthetic leather base cloth adopts textiles mostly, and textiles is to adopt chemical fibre as main raw material, and therefore the sanitation performances such as poisture-penetrability of this synthetic leather are far away from natural leather.Also have its scrim material of a kind of synthetic leather to adopt superfine fibre to make in the prior art, but the fineness of its fiber of superfine fibre does not still reach natural leather, the reparation technology complexity of while superfine fibre, manufacturing cost height.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of prior art, the synthetic leather that a kind of cost is low, performance is good is provided.
Technical solution of the present invention is the base cloth of synthetic leather to be adopted the regenerated leather of dry production.
Dry process for preparing regenerated leather technology described in the present invention is open at Chinese patent CN1330182.
The manufacturing technique of synthetic leather of the present invention is as follows:
Adopt " dry process for preparing regenerated leather " to make regenerated leather;
Regenerated leather is flooded polyurethane solutions make base cloth;
Finishing.
Adopt its raw material of regenerated leather of dry production to adopt natural leather angle material among the present invention, belong to the refuse reclamation of environmental protection, and production cost is low, its fibre composition is a natural leather fiber simultaneously, and various physical properties and natural leather are close.The regenerated leather that adopts this dry production has the advantage that cost is low, performance is good as the synthetic leather of base cloth.
Description of drawings
Further illustrate particular content of the present invention below in conjunction with drawings and Examples.
Fig. 1: the section structure diagrammatic sketch of the embodiment of the invention 1;
Fig. 2: the section structure diagrammatic sketch of the embodiment of the invention 2.
The specific embodiment
Embodiment 1: the use for synthetic leather of present embodiment is in the footwear upper leather, and its structure comprises three layers, i.e. top layer 1, intermediate layer 2 and base cloth 3.
Its technology is as follows:
At first, adopt " dry process for preparing regenerated leather " technology to produce regenerated leather, in order to make product reach kishke feel and necessary physical strength, regenerated leather in being 10% polyurethane solutions, concentration is flooded, base cloth after will flooding is again put into coagulating basin and rinse bath and is solidified and clean, send into the drying in oven leveling again, made the embryo cloth that contains sponge-like polyurethane, embryo cloth is polished the two sides of embryo cloth on buffing machine, on splitter, carry out splitting again and make footwear upper leather base cloth by 1.2 millimeters.This base cloth carries out the polyurethane solutions slurry of overcoating 20% on the wet method streamline, make its thickness reach 0.5 millimeter, forms the intermediate layer, sends in the coagulating basin once more and solidifies, and puts into rinse bath and cleans, and send into oven for drying.Send at last and carry out top finishing on the coating machine, and embossing and upward optical processing of surface are carried out in the top layer with knurling rolls.
Embodiment 2: the synthetic leather of present embodiment is the general service synthetic leather, and its structure comprises two-layer, i.e. top layer 1 and base cloth 3.
The technology of present embodiment is as follows:
At first, adopt " dry process for preparing regenerated leather " technology to produce regenerated leather, regenerated leather in being 15% polyurethane solutions, concentration is flooded, base cloth after will flooding is again put into coagulating basin and rinse bath and is solidified and clean, send into the drying in oven leveling again, made the embryo cloth that contains sponge-like polyurethane.Select the release liners of suitable decorative pattern again for use, film on the polyurethane slurry that uses suitable color on the film applicator carries out, oven dry, with polyurethane slurry that coating on the release liners and base cloth is bonding, drying and ironing are handled again, release liners are peeled off again, and just stay uniform surface decoration layer on leather surface.
Claims (4)
1, a kind of synthetic leather comprises top layer and base cloth, it is characterized in that: described base cloth (3) adopts the regenerated leather material to make.
2, synthetic leather according to claim 1 is characterized in that: described regenerated leather adopts the dry technology for production manufacturing.
