Abstract

The invention relates to the vegan leather which is produced by using the Kombucha tea fungus, and production method thereof.

Description

VEGAN LEATHER AND PRODUCTION METHOD THEREOF
TECHNICAL FIELD
The present invention relates to a production method of vegan leather.
In particular, the invention relates to the vegan leather which is produced by using the Kombucha tea fungus, and production method thereof.
PRIOR ART
Vegan lifestyle does not consider the use of animal products appropriate in order not to harm animals and the natural habitat of animals. In many areas, products are produced from alternative raw materials and/ or alternative methods, suitable for people who adopt a vegan lifestyle. The textile industry is one of the sectors that causes significant damage to the natural habitats of living things. In recent years, in parallel with the increasingly sensitive approaches towards living life and natural habitats, some fabrics with natural content have started to be produced. In the leather category, PU (polyurethane) fabric, which is artificial leather, has been developed as a solution to this demand. PU (polyurethane) fabric is a polyester- based fabric that is highly harmful to nature, although it does not technically harm any living thing. It is made of polyester, nylon and plastic. PU fabric is not a vegan product and causes serious damage to nature. In this sense, there is a need for new vegan leather production methods in the technical field that do not harm natural creatures and natural resources.
In a search of patent and literature performed for the state of the art, Patent publication no. CN110344276 A has been found. Said patent patent publication describes a bio-based high gloss vegan leather and the production method of this vegan leather. Accordingly, the method includes the process steps of pulping a fiber slurry with a disc mill, spraying the slurry onto a paper machine web, pressing and drying to obtain a vegan leather base, sizing the vegan leather sole, drying, and polishing, coating thereof. As a result, due to the above-mentioned disadvantages and the insufficiency of current solutions, it was necessary to make an improvement in the relevant technical field.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to vegan leather and its production method that meets the above-mentioned requirements, eliminates all disadvantages and brings some additional advantages.
The main purpose of the invention is to obtain 100% organic vegan leather that does not harm living things and nature, completely dissolves and disappears in nature.
The aim of the invention is to produce a vegan leather that dissolves in nature much faster than the Pll fabrics known in the state of the art. While the P.ll fabric, which is a nylon base solution offered under vegan leather, dissolves in nature between 400 and 500 years, the vegan leather subject to the invention begins to dissolve in 20-30 days and disappears completely in 2 to 3 months.
The aim of the invention is to develop completely natural vegan leather that can be dyed with food dyes. Thanks to the vegan leather of the invention, it is possible to prevent the use of dyestuffs used in the technical field and harmful to the natural environment. At the same time, while P.ll artificial leather harms the human skin due to the harmful chemicals in its structure, the Kombucha fungus used in the present invention has no chemical side effects.
The aim of the invention is to present a production method in which the water used can be recycled and reused. In the method of the invention, unlike the P.ll leather, the water used can be reused at a rate of 100% by being turned into a beverage, such as tea, or in the health field.
The structural and characteristic features and all advantages of the invention will be more clearly understood from the detailed description given below. Therefore, the evaluation should be made by taking this detailed description into consideration. DETAILED DESCRIPTION OF THE INVENTION
In this detailed description, the preferred applications of the vegan leather and production method thereof according to the invention are explained only for a better understanding of the subject matter and without any limitation.
The invention relates to vegan leather and the production method of said vegan leather. In the production method of the present invention, tea is first brewed. As for tea, preferably black or green tea is used. However, the aforementioned tea variety is not limited to these. The type of tea used directly affects the color of the vegan leather to be obtained. During the tea brewing step, sugar is added to the tea. The amount of added sugar is effective in shortening the production process. After the tea is brewed, the tea is cooled. In a preferred embodiment of the invention, the tea is cooled to a temperature range of 16 °C to 21 °C. In the next process step, Kombucha tea fungus is added to the tea containing sugar and brought to room temperature. In the process of adding Kombucha tea fungus, the temperature of the tea should not be high enough to cook the Kombucha tea fungus.
The tea, which is cooled and to which Kombucha tea fungus is added, is covered such as to take air in and is expected to undergo fermentation. Fermentation is carried out under normal conditions in a dark and dry environment.
After fermentation, a new fungus forms at the top. The vegan leather according to the invention is obtained from the newly formed fungus. The new fungus formed at the top is removed from the tea and washed and filtered to clean the tea residue. In order to prevent the new fungus extracted from the tea during the drying step from shrinking, the fungus in question is hooped and left to dry in a hooped form. In this way, it is possible to dry the fungus, and alter and transform the fungus formation into a fabric.
The new fungus, which is completely dried in the drum, is covered with a mixture of oil and wax and taken to rest. By means of coating with oil and wax, the elasticity of the fungus is increased and softened. In the method of the present invention, one or more of petroleum jelly, olive oil, almond oil, coconut oil can be used as oil. In the coating process step, it is possible to restore flexibility to the fungus that has been subjected to hooping and drying. In this sense, the aforementioned process step is a preparation for the step of making it prepared for sewing.
In the resting process step, the excess oil on the fungus covered with the mixture is removed, then it is wrapped with a cloth and kept in a dark and dry environment. At this step, the fabric used for wrapping is preferably cotton fabric. It is thereby ensured that the leather obtained remains moist, does not lose its softness and vividness, and integrates well with the mixture.
In the next process step, the leather obtained from the new fungus is interlined. The interlining step is carried out under high temperature. The interlining process is important in terms of increasing the strength of the leather and turning it into a fabric. Undesirable situations such as breaking, drying and tearing are prevented in the interlined leather. According to the invention, the interlining process is preferably applied with thermo-adhesive interlining whereby the interlining is completely invisible. After interlining, the leather is lined and turns into a wearable fabric that can be combined with other fabrics, and then becomes a product that can be worn.
Since the vegan leather is obtained from the fungus of Kombucha tea, a large amount of water is used in its production. However, the water used is fermented with fungus and turns into a useful tea. The newly formed tea is the Kombucha tea which is very beneficial for health.
The production period of the vegan leather according to the invention is up to 20 days and this period can be taken up to a week with factors such as the correct temperature and humidity. The Kombucha tea fungus used are very suitable for mass production, as they take the shape of the container in which they are formed as well as they develop quickly in the appropriate environment. Kombucha tea fungus can be used over and over again. Therefore, an economically viable production process is provided.
In order to solve the problems in the technical field and to fulfill the mentioned purposes, the invention is a vegan leather production method comprising the following steps: tea is brewed,
- sugar is added to the tea,
- the brewed and sugar-added tea is cooled,
- Kombucha tea fungus are added to the cooled tea,
- the tea, to which Kombucha tea fungus is added, is kept subject to fermentation,
- a new fungus forms on said tea after the fermentation,
- the newly formed fungus is removed from said tea and tea residues are cleaned therefrom,
- the cleaned new fungus is left to be dried after being hooped,
- the dried fungus is covered with a mixture containing oil and wax in the hooping step for softening said fungus,
- the leather covered with said mixture is left to rest by being wrapped by at least one fabric,
- the leather is interlined after the wrapping process, and made into sewable leather.
