TR TR TR DESCRIPTION POLYMER BLEND WITH OLIVE EXTRACT-BASED FILLER FOR NATURAL LEATHER PRODUCTION TECHNICAL FIELD The invention relates to the use of polymer mixtures with biopolymer filler material in leather production processes for the production of natural leather materials. KNOWN STATE OF THE TECHNIQUE Natural leather production, which has a traditional production model, has continued in the same way for many years in terms of production model, although it has kept up with the developing industry in terms of chemicals used. Natural leather production; It is defined as the transformation of perishable and organic raw leather into a more resistant and non-degradable form against physical and chemical factors as a result of being treated in a leather processing cabinet using a wide variety of chemicals and water. Leather production processes in brief; It consists of soaking, softening, clay removal, liming, descaling, straw, degreasing, pickling, tanning, basification, chrome retanning, neutralization, retanning, dyeing, oiling and finishing processes. The basic structure of rawhide is collagen-containing protein, and the amino and carboxyl reactive bond sites are converted into an indestructible form by the effect of the tanning agents used in the tanning process, and then the retanning process is started. Retanning process, which means tanning for the second time; It is a process in which the leather is given the fullness, handle and desired physical fastness, and in this process, various tanning substances such as chromium, vegetable tannins, aldehyde, polymer, synthetic tannins, resin, and the like are used. The finishing process is; It is the last processing step in the leather processing steps to give the leather its final appearance and properties. For this reason, it is also defined literally as finishing or finishing processes. Different percentages of polymer emulsions, known as binders, are used in the finishing process. While polyacrylics and polyurethanes are generally preferred, binders enable the chemical bonding of non-binding pigment dyestuffs on the surface of the leather. In addition to the finishing process, there are many chemicals used for different purposes such as waxes, hydrolacs, gels, penetrators, fillers (filler chemicals). In the finishing process, the leather is given the desired color tone, final attitude and fastness, and the product is protected against external factors due to its long life. In the patent and literature research conducted on the known state of the art, various documents regarding the natural leather production method/process were identified. In the American patent with publication number U86395040, a method involving the production stages of wet-blue leather is described. Accordingly, liquid chromium solution is applied to the leathers in question at a pH of 3.5 or lower, and then the pH level in question is increased to at least about 6.0 or above. In the next processing step, the skins; It is subjected to a vegetable tanning process and mixed with lubricants and dyes in a series of dye baths. The patent application with publication number US4784664 A is related to a method that gives chrome character to leather without using chrome. In said method, the chrome-free tanning process includes the steps of pre-tanning a hide with a chromium-free tanning agent until the shrinkage temperature is approximately 170-185°F. Then, the used hide is soaked in an acidic salt water. In these stages, pretanning agents, herbal extracts, neutralizing agents and retanning and finishing agents are used, all of which have a pH between 2.5 and 3.5 and do not contain chromium. The patent application with publication number U83930921 A is about the finishing process. According to the document, in the process, the leather to be treated is superimposed on a release layer and treated with a thermoplastic, adhesive acrylic polymer coating. After the application of heat and pressure, the skin is separated from the said layered structure. The patent application with publication number U82205882 A is related to a method developed for the tanning of leather. In the described method, the skin is exposed to the action of an acidic polymeric substance in which the acidity arises from carboxyl groups attached to aliphatic carbon atoms. The patent application with publication number U83068059 A is related to the vegetable tanning process. In the document, the skin and its section, whose pH range is around 9-12, are brought to pH 2-6 with an acidic solution. It is stated that it is treated with acidic solutions to balance the pH. BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a method of obtaining natural leather that meets the above-mentioned requirements, eliminates all disadvantages and brings some additional advantages. The aim of the invention is to obtain a more organic and environmentally friendly natural leather thanks to a polymer mixture with biopolymer filling.

The content of the biopolymer mixture obtained from olive extract mentioned here (preferably Biolive®) is the biopolymer disclosed in patent publication TR201906799, which is incorporated herein by reference. The polymer mixture in question contains a biopolymer of which the filler is essentially derived from olive extract. The olive extract that constitutes the filler is preferably obtained only from olive waste, preferably from the whole (pomace obtained after olive oil production or olive pits obtained after table olive production) and the filler does not contain petroleum-based additives. The expression "olive extract" used throughout the text includes the pomace used in olive oil production and the resulting olive waste, as well as the olive pit waste produced in table olive production. The structural and characteristic features and all the advantages of the invention will be understood more clearly thanks to the detailed explanation. For this reason, the evaluation must be made taking into account the detailed explanation in question. DETAILED DESCRIPTION OF THE INVENTION In this detailed description, the development of the subject of the invention is explained without any restrictions and with references to examples only to explain the subject better. The invention is related to the use of a polymer mixture containing olive extract with filling properties in the production of natural leather. Biolive® ingredient is the biopolymer disclosed in patent publication TR201906799, incorporated herein by reference. In the invention, 1-20% is used in the pickling process and in the tanning process (biopolymer mixture obtained from olive extract). From the mentioned quantity values, the percentage amounts excluding the finishing process step are given by calculating the polymer mixture in kilograms or grams based on the weight of the leather. In the finishing process step, the total amount of finishing chemicals is the amount used. In the production of natural leather, a polymer mixture containing olive extract with filling properties; It can be used in various processing steps such as pickling, tanning, retanning and finishing.
