Description

A TRANSFER MEMBER FOR IMPARTING A FINISH LEATHER
This invention relates to a transfer member for treatment of leather so as to impart gloss properties thereto.
PRIOR ART
It is generally known that hide is subjected to a chemical treatment to produce leather. However, if an appearance or finish is required, it was hitherto necessary to subject leather to an additional step of chemical treatment so as to impart a gloss appearance. It would be apparent that such a known process had the disadvantage of an additional step of chemical treatment.
A further disadvantage of the known art is that associated with split leathers. In accordance with the known art, split leather was subjected to the step of lamination, pigmentation or transfer foil so as to upgrade or improve the quality of split leather. Thus, split leather is impregnated with binder and waxes so that when compressed a release takes place from the plate. After impregnation it is then laminated, pigmented or treated with a transfer foil. A disadvantage is that the fiber bundles do not get concealed and continue to be in a standing position.
Yet another disadvantage is that of the chemical adhering to the plate.
OBJECTS OF THE INVENTION
An object of this invention is to propose a transfer member for treatment of leather and so as to impart gloss properties thereto.
Another object of this invention is to propose a transfer member for treatment of leather and so as to provide a uniform feel to leather.
Still another object of this invention is to propose a transfer member for treatment of leather and which provides good plate releasing properties.
Yet another object of this invention is to propose a transfer member for treatment of leather and which provides a good sealing of fibers.
A further object of this invention is to propose a transfer member for treatment of leather and which provides grain flatness.
Another object of this invention is to propose a transfer member for imparting a gloss together with a colour, print or metallic finish to leather.
DESCRIPTION OF INVENTION
According to this invention there is provided a transfer member for imparting gloss properties to leather comprising a gloss film of at least two co- extruded layers and, wherein, the inner layer is the active or gloss layer and the outer layer is a colayer, a carrier or substrate layer releasably held to said outer layer.
The gloss film preferably comprises three coextruded layers and wherein the inner layer has the gloss properties, an intermediate layer is the colayer which contributes to the bulk properties of the film and further is a storage layer for the migratory chemicals, and an outer layer which is a colayer. A carrier such as paper is adhered to the outer layer.
The inner layer comprises a resin layer of isotactic polypropylene singularly or in combination with random ethylene propylene copolymer present in an amount of 0 to 40% by weight. The intermediate layer comprises isotactic polypropylene and migratory additives, which are antistatic and slip agents. The outer layer also comprises isotatic polypropylene with an additive, which is an antiblock agent. A stiffener such as paper is adhered to the outer layer by means of an adhesive.
The inner layer may additionally comprise migratory chemicals present in the amount of 0-5%, migratory chemicals being antistatic and slip agents selected from erucamide stearamide, silicon oil, stearic acid and stearates used singularly or in any combination thereof. Further, the inner layer may comprise an antiblock agent present in the amount of 500-4000 PPM. The antiblock agents are selected from silica, silicate, clay, talc and quartz comprising singularly or in any combination thereof. The haziness or glossy- ness of the inner layer is varied by changing the thickness of the inner layer and quantity of migratory chemicals and antiblock agents in the composition.
The migratory chemicals comprising said antistatic and slip agents are present in the amount of 500- 10000 PPM by weight in the intermediate layer. The outer layer is identical to the inner layer and comprises isotatic polypropylene in combination with rendom co-polymer of ethylene propylene, and where ethylene propylene is present in the amount of 0 to 40% by weight. The film further comprises a paper layer adhered to the outer layer. The paper layer is a cellulosic paper such as cromo art paper and
2 having a granrmage of 30 to 100 gms/m .
The isotatic polypropylene present in the layers has an average molecular wt . of 25000 to 1 , 000 , 00 , a melt flow index of 1-25 at 230°C/2.16 kgs and density of 0.892 to 0.92.
As herein described above an antiblock agent is provided in the outer layer. However, in the instance of a film having three layers, the antiblock agent may or may not be provided in the outer layer. In accordance with another embodiment, an antiblock agent is provided in the outer and in the inner layer. The outer layer may be subjected to a corona treat- ment, flame treatment or chemical treatment so as apply an adhesive thereon to secure a paper layer therewith. The paper layer acts as a stiffener and absorbs excess heat during the plating of the leather.
The transfer member of the present invention has a thickness of 8 to 45 microns. If the thickness is greater than 45 microns, it does not affect the workability or properties of the film, but no advantages are derived therefrom and only adds to the end cost of the film. If the thickness is less than 8 microns, the required quality and properties are then not achieved. Both the inner and outer layers should have sufficient thickness in the instance of two layers film, in order to store and release the chemicals therefrom. Similarly, the inner, intermediate and outer layers should have sufficient thickness in an three layers structure for storage and release of said chemicals. Preferably, and without implying any limitation thereto the transfer member has a thickness of 12 to 45 microns.
The inner and intermediate layers have each a thickness of 2 to 8 microns and preferably a thickness of 2 to 5 microns. If the thickness of the inner layer is less than 2 microns, then gloss would reduce. If the thickness is more than 8 microns, and the outer, intermediate and inner layers are extruded then problems may arise in the coextrusion of the 1 ayer s .
