Description

1228455 A7 V. Description of the invention (1) Manmin's technical know-how The present invention relates to a kind of transfer element for leather processing to impart its luster properties. Knowing Skills I It is generally known that hides are subjected to a chemical treatment to produce leather. However, if surface treatment or appearance is required, the leather has to undergo an additional chemical treatment step to give a glossy appearance. Obviously, this known method has the disadvantage of an additional chemical treatment step. Another disadvantage known in the art is related to split leather. According to the conventional art, the folio leather is subjected to the steps of laminating, coloring or transferring materials to improve or improve the quality of the folio leather. Therefore, the split leather is impregnated with the adhesive and the soil, so that the peeling effect occurs from the veneer when compressed. After impregnation, it is laminated, colored or treated with cast iron. The disadvantage is that the fiber bundles are not concealed, but remain in an upright position. , Wen Another disadvantage is that chemicals adhere to the board. Invention n Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. One of the goals of this invention is to propose a new transfer element for leather processing to give it luster. Another object of the present invention is to propose a transfer element for leather processing to provide a uniform touch to leather. Another object of the present invention is to propose a transfer element for leather processing to provide good board peeling properties. Another object of the present invention is to propose a transfer paper for leather processing. The paper size is suitable for China National Fresh (CNS) A4 specifications (0 × χ297). — 1228455 A7 B7 5. Description of the invention (2), which provides Good fiber sealing effect. Another object of the present invention-the object is an initiative-a species which provides the flatness of the leather front. Transfer of leather treatment The other aspects of the present invention-leather gloss and -㈣P _ material transfer, used to provide leather gloss "color, printing or metallizing surface treatment. Detailed description of the invention as the present invention provides a method for the secret name + Gan, a kind of transfer element for ^ leather properties of ^ ^ _, composed of ^ co-extruded layers, the inner layer is a reactive or glossy layer, and the outer layer is a common layer, = visitor or The substrate is adhered to the outer layer in a peelable manner.

The tT ^ 睪 film consists of two co-extruded layers, and its inner layer has a negative glossiness. The intermediate layer is a co-layer that constitutes the bulk properties of the film and further serves as a storage layer for fluid chemicals, and- As the outer layer of co-layer I. A carrier member, such as a paper system, is adhered to the outer layer. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, etc. One of the resin layers of stereotactic polypropylene itself or its composition with the random polymer of women and women is in an amount of 0 to 40% by weight presence. The middle layer contains isotactic polypropylene and mobility additives. The additives are antistatic and slip aids. The outer layer also contains isotactic polypropylene and an additive, which is an antiblocking agent. A reinforcing member such as paper is adhered to the outer layer by an adhesive. The inner layer may additionally contain a mobile chemical substance present in an amount of 0-5%, the mobile chemical substance being selected from the group consisting of piramine, stearylamine, silicone oil, stearic acid, and stearic acid. Antistatic agents and slip agents are used alone or in any combination thereof. Furthermore, this inner layer can also cover the paper.

Description of the invention (including 500-4000 ppm The anti-blocking agent is present in an amount. The anti-blocking agent is selected from the group consisting of stone oxide, stone vinegar, clay, talc, and quartz, which are present alone or in any combination thereof. The turbidity of the inner layer Or the gloss is changed by k-thickening the thickness of the inner layer and the amount of mobile chemicals and anti-blocking agents in the composition. The mobile chemicals include antistatic agents and slip agents, and are based on An amount of 500-10000 ppm by weight is present in the intermediate layer. The outer layer is the same as the inner layer, and contains an isotactic polypropylene and an ethylene-propylene random copolymer < combination dow, and its ethylene-acrylic group It is present in an amount of 0 to cent% by weight. The film further includes a paper layer adhered to the outer layer. The paper layer is a cellulose paper such as Kolomo fine art paper, and its gram weight is 30 to 100 grams. / Square meter. Exists in this The isotactic polypropylene in the isolayer has an average molecular weight of 25,000 ^ 000,000, a dazzling flow index of 1-25 kg at 2300c / 2 and a density of 0.892 to 0.92. As mentioned above, in the outer layer There is an antiblocking agent in the film. However, when the film has three layers, it may or may not have an antiblocking agent in the outer layer. As another specific example, an antiblocking agent is provided in the outer layer and the inner layer. The outer layer may be It is treated by the activation step of corona treatment, flame treatment or chemical treatment to apply an adhesive on it and then fix a paper layer. The paper layer acts as a reinforcing member and is absorbed during the leather ink-refining process. Excessive heat. The thickness of the transfer element of the present invention is 8 to 45 microns. If the thickness is greater than 45 microns, it does not affect the processability or properties of the film, but it does not produce any advantages, but only increases the thickness of the film.

1228455 V. Description of the invention (4): Two = called the required quality and properties. In the case of the two-layer film ... the two and two inner layers should have sufficient thickness to store and release them. Like a crustacean, in the case of a three-layer structure, the outer layer, the middle layer and the inner layer should have sufficient thickness. Thickness to store and release the chemical. Preferably, and with no intentional restrictions, the thickness of the transfer element is pure micron. The thickness of the inner layer and the middle layer are each 2 to 8 microns, and the preferred thickness is 2 to 5 U meters. The thickness of the right inner layer is less than 2 micrometers, which will reduce the gloss. The thickness of the right inner layer is greater than 8 micrometers, and the outer layer, the middle layer and the inner layer are extruded.
