According to shoe manufacturers, the use of natural leather has always been very different from synthetic materials. Leather is made from animal skins and is a by-product of the meat industry, while leather is also a renewable resource in nature.

If the skins do not turn into leather, they should be buried and their use is very limited. On the other hand, artificial materials are based on oil and are the product of the chemical and man-made industries. These industries use fossil fuels, which are certainly not renewable sources. Also, contrary to the claims of synthetic leather manufacturers that these products are similar to natural leather, it must be admitted that these products are completely different from leather.

Environmentalists, on the other hand, are faced with the dilemma of whether to buy shoes made of leather, which is a natural material but requires the slaughter of animals and coping with it. It is not easy, or they have to use shoes made of synthetic plastic materials whose resources are raw materials and valuable non-renewable energy sources.

To solve this problem, we need to think of a new source that, while similar to leather, is not a farm but a laboratory.

 

Natural Leather

In its simplest form, animal skins are made up of a chain of collagen, water, creatine, and a variety of proteins. The resistance of the skin is due to the structure of the collagen fibers that are slipped together by the free molecules of water to provide the necessary flexibility for the animal to move freely. In addition, water bonds form part of the protein structure. If these bonds are removed by drying the skin too much, the skin will start to harden due to the cross-linking of the collagen chain.

Tanning involves replacing these watery bonds with tanning agents to create the necessary flexibility and maintain physical quality while protecting the skin. During tanning, unwanted material is removed and replaced with materials that prevent bonding between the collagen chains and keep the leather structure soft and supple.

 

Biological Production

Launched in 2011, Modern Meadow has introduced a material called “bio-leather-made leather” in October called Zoa, which is a revolutionary alternative to natural leather.

They claim that the prototype material with a capital of more than $ 50 million has been successfully built, and that the possibility of creating a new and larger laboratory has been increased by 60 employees for production.

Central core DNA manipulation is a process that Modern Meadow has performed to produce Zoa.

DNA is a molecule that controls the functioning of an organism with its own structure (just as software codes determine how a computer program works).

Modern Meadow takes a pair of DNA and replaces it with a new pair of DNA. The sequence of data determines the information available to build an organism (similar to the way alphabetic letters are arranged in a certain order to form a word and a sentence).

This DNA can be modified to produce the desired amount of collagen. But where does the original DNA come from?

Until two years ago, Modern Meadow used engineered tissue to produce collagen on a laboratory scale, but today it uses a dedicated biological production process that is able to produce new non-animal collagen compounds that are claimed to be able to compete with collagen found in it. Be the market.

The technology uses the latest version of DNA editing tools to specialize in collagen engineering to create yeast cells. These cells are optimized to produce the desired collagen and in the required amount.

New DNA is inserted into cells and multiplied. The basal cells are the building blocks of living organisms, and the cells are nourished with nutrients, and these nutrients are converted into energy, and the cells multiply rapidly, from tens of cells to billions of cells.

These cells produce collagen and other proteins necessary for leather production. Collagen groups together form a triple spiral collagen molecule.

The triple helical structure of the collagen then forms a network of nanofibers that join together to form the fibers, and eventually the fibers together to form the structure of the original material.

Other processes are performed on these protein structures to create the final product, which is simply tanned and completed. Because the material is not animal-derived, there is no need for lubrication to remove hair, a campaign to remove unwanted tissue, lubrication, degreasing, and the preparation of ashtrays, as these materials are uniform and perfectly flat.

 

Practical Advances

This article simply examines a complex process. Given the obvious practical advances in this area, there seem to be a lot of detail that the company prefers not to disclose. These materials are produced in the form of perfectly uniform plates with regular sizes that are competitive with natural leather because the leather is different from one skin to another.

Another advantage of these materials is that they do not have the effect of knives, barbed wire and growth marks, so they can be easily cut and have less debris like other synthetic plastic materials. According to Dave Williamson, head of operations at the company, the process is designed to make production easier with existing industrial facilities.

Of course, this requires proper investment. According to him, large-scale collagen production and transfer to local factories and leather factories are possible for the final and complete process. A special feature of these materials is that the different parts of a page can have different properties, for example, the appearance and the hand can be changed from one part to another in a controlled way.

Theoretically, it is possible to produce materials for specific designs with this method. Dave Wiliamson states that in terms of cost, the new materials are competitive with natural leather. He adds that Modern Meadow isn’t really looking for a complete replacement for natural leather, but is looking to produce new materials that have a place in the market.

Shoes made from such materials can be of interest to vegans, vegetarians and those who oppose killing animals. It can also be considered by shoe manufacturers with a sarcastic wish that “I wish we could have square-shaped cows.”

The purpose of the Dalir leather industry is to satisfy all sections of society, including vegans, and to try to update its materials and products as much as possible.

Combination of the feel and color in the heel and insoles of leather shoe – heel industry

Combination of the feel and color in the heel and insoles of leather shoe – heel industry

In this collection, once again, the possible beauties for combining emotion and color_ the industry of heels and leather shoes insole is depicted, Combination of the feel and color in the heel and insoles of leather shoe – heel industry.

Although making “feeling” is beautiful but when it is supposed to be in a connected body (for example, in shoes, including surface, surface decoration, heel, and insole), it must also have a coherent logic.

In the first picture, the leather shoe is made up of a set of independent pieces that their size and colors, give it the harmony.

In such a situation, the heel is also made in this way. It should be noted that the role of colors in this shoe is very important.

Combination of the feel and color in the heel and insoles of leather shoe - heel industry

In the second picture, the coordination is more focused on the talc shaped surface and heels.

Although the heel and insoles of leather shoe are very beautiful and eye-catching independently, but the plenty of materials used and the use of wood color in part of it, gives such a prominence and effect that put down its seamless.

In fact, in this shoe the heel plays an important role, which cannot be an advantage.

Every beautiful element should be beautiful in combination with other elements, and if it looks beautiful more than other elements, the set will lose its attractiveness.

In this collection, once again, the possible beauties for combining emotion and color_ the industry of heels and leather shoes insole is depicted

The third picture can only be a scenic and promotional photo. The balls under leather shoes cannot play any role in it.

We can say it is a heel-free shoe, and the location of these balls is not appropriate, based on design logic and shoe standards and regarding foot health.

Combination of the feel and color in the heel and insoles of leather shoe - heel industry

In the fourth photo, the heel and insoles of leather shoe form a single body.

As if the shoe is produced and then placed in a keeping chamber for care.

The design of these single and continuous bodies, however simple it looks, is also subject to many limitations in terms of both the health of the foot and the beauty chance of the shoe set.

Usually, this king of combined insole heal are less used in classic and eye-catching leather shoes, because it do not evoke an image of a special and expensive leather shoe, even with any attempt to make it.

In this collection, once again, the possible beauties for combining emotion and color_ the industry of heels and leather shoes insole is depicted

Making this heel of shoe is inspired by European pottery pictures of three centuries ago and women’s aristocratic cloths.

Its flashy colors and crass form evoke the traditional tastes.

The result is leather shoes that attract the special or maybe very special people.

Combination of the feel and color in the heel and insoles of leather shoe - heel industry

The latest heel and insoles of leather shoe is also designed like the above shoe, but it the modern elements is used to design the heels.

The glass heel of this shoe, which shows a picture of a steady man with a dolphin mask, is very beautiful.

The glory of this heel is not only its shape, but also its upper part, as it seems the insoles of the shoe is attached to the heel with a narrow backrest.

The precision in shoe design shows that its form is an inspirational form of fish face that both eyes are closed.

This is an example of a beautiful creativity in the combination of heels and surface of the shoe to achieve an artistic and creative design.

How to make leather jackets

How to make leather jackets

Using Leather has different conditions because of the material and special properties that it has, and for example, when you are making a leather coat, you have to adhere to more points than a fabric coat, (Learn how to make leather coat ).

If you want to know tips about sewing with leather, especially if you want to know how to make a leather coat, do not miss the site of Dalir’s Leather Industry.

The needle tip is very sharp in training how to make a leather coat, In fact, every time a needle enters into leather, a small cut is created and the string passes through it.

With the increasing number of layers of leather, you should use thiner needles. Among needles, numbers 11, 14, and 16 are most often used.

If you encounter problems such as missing a stich or tearing the string repeatedly, use a needle with a different number.

Learn how to make leather jackets

How to make leather jackets,Sewing string:In the manufacture of leather jackets, durable string should be used., Learn how to make leather jackets
Stitch size

Because the needle in this kind of training cut the leather, stitches should not be too small.

Before you start sewing, , test stitch and the kind of string on a small piece of the leather.

Also keep in mind that start training about half a centimeter distance from the leather edge.

However, in some cases where the size of the Stitch is large, the back movement is used to seal the seams, but keep in mind that the string strain should not be too much.

Sewing string:
In the manufacture of leather jackets, durable string should be used. Rayon strings are much more suitable than cotton string or a combination of them.

Also, special sewing string for forty pieces and needlework are suitable in sewing leather. To test the string’s strength, open it about 30 cm from the pulley and pull it with two hands. If the string is torn, its durability is not suitable for leather sewing.
