Fabrication hard leather

Leather is a material loved by many for its flexibility and durability. It is made from tanning animal skins or hides and many different animals are used to make leather. Leather has four basic grains or qualities; those are full-grain leather, top-grain leather, genuine leather, and corrected-grain leather. Full-grain leather is characterized by its luxurious, smooth surface and it has few, if any, flaws. It is the most popular type of leather.

Leather production processes

VIDEO ON THE TOPIC: How leather is made

Faux leather, also known as synthetic leather, is a petroleum-based alternative to genuine leather. While faux leather has many of the same desirable attributes of genuine leather, it is not necessary to harm animals to create this substance. Like real leather, faux leather is soft to the touch, and it is water-resistant. Therefore, this fabric is highly resistant to stains, and it is easy to clean.

While synthetic leather is less durable than real leather, it is resistant to both abrasions and cuts, which makes it an ideal fabric for upholstery in homes with children or pets. Therefore, some manufacturers experiment by making yellow, green, purple, or even blue synthetic leather to differentiate their goods from the genuine leather market. Since faux leather is almost as good at insulating body heat as normal leather, it is a popular fabric for outerwear garments such as jackets and coats.

Even the most uninitiated fabric enthusiasts, however, can usually tell the difference between pleather and real leather by touch; synthetic leather feels like plastic to the touch, which is single greatest factor differentiating this type of fabric from real leather. In recent years, however, some manufacturers have started making vegetable-based synthetic leather , which seemingly solves both the ethical concerns surrounding genuine leather production and the environmental concerns regarding faux leather production.

One of the first forms of faux leather was called Presstoff, and this type of fabric is still in production today.

This fabric was invented in Germany, and it was used widely in the war effort since the use of genuine leather was strictly rationed. Production of Presstoff never became significantly popular outside Germany, however, and consumers rapidly came to prefer other leather alternatives with more desirable attributes.

Synthetic leather came onto the international fabric scene with the invention of Naugahyde in This substance was formulated by U. Rubber Company, which had been founded in After years of dedicated research, the engineers at U.

Rubber developed this viable alternative to leather, which was originally used in handbags. This substance became popular in various industrial applications throughout the s, and in the s, the U. Armed Forces used Naugahyde in various aspects of the war effort. While some historians may contend that the history of faux leather stretches back as far as the 15th century, these Chinese attempts at synthetic leather manufacture never reached any notable scale.

It was only with the development of petroleum-based plastics at the end of the 19th century that it became viable to mass produce a viable alternative to leather. Following the lead of U. Rubber, a variety of other entities started making artificial leather products from the s onward.

In the s, the environmental movement led to greater public awareness of the dangers of synthetic fabrics, and the public perception of faux leather production took a turn toward the negative. While these attempts have been largely unsuccessful, a few companies have succeeded in creating non-PVC versions of artificial leather in recent years.

Manufacturers may use a wide variety of different production processes to make faux leather. Presstoff, for instance, is made by treating paper pulp with a special type of resin that provides this plant-based material with greater durability.

Most faux leather on the market today consists of a base textile covered with a plastic material. The two plastics most commonly used in synthetic leather production are polyurethane PU and polyvinyl chloride PVC , and while the processes used to make these two plastics are somewhat different, the processes of binding these plastics to their underlying fabrics are highly similar. Most faux leather manufacturers use cotton or polyester as the base material for their fabrics.

The types of polyester or cotton fabrics used as the base for artificial leather are usually porous and rough, which means that they need to be specially manufactured. Next, faux leather manufacturers need to formulate the plastic substances that they will bind with their base fabrics. PVC, for instance, is made by combining constituents of salt and petroleum. Manufacturers produce chlorine by exposing salt to electrolysis, and they then combine this chlorine with ethylene, which is derived from petroleum.

The resulting substance is called ethylene dichloride, which is then converted into vinyl chloride monomer at high temperatures. Next, these monomers are transformed into polymers with polyvinyl chloride resin. The PVC used in artificial leather production must be flexible, so manufacturers add plasticizers this petroleum product to make it bind to the base fabric used in ersatz leather production.

The process used to create PU is somewhat more complex, and it involves isocyanates, polyols, and various additives. The various polymers used in PU production are reacted to each other, and they are then processed. PU used in fake leather production is exposed to plasticizing additives to achieve a flexible final material. A variety of processes may be used, but they generally involve melting the plastic and overlaying it on the base textile.

Once the plastic has been bound to the underlying fabric, it is cut into the desired shape and size. In most cases, faux leather is sold by the yard in long strips. Faux leather is a direct replacement of leather, and it is, therefore, used for the same applications for which genuine leather is used. For instance, upholstery is one of the most common applications of faux leather.

Sofas, car seats, chairs, and coffee tables all commonly feature synthetic leather coverings, and this substance is also used in certain types of wall hangings. In the world of apparel and accessories, faux leather is commonly used in handbags, shoes, boots, gloves, and hats. Other examples of faux leather applications include suitcases, briefcases, watch bands, smartphone cases, and camera cases.

The largest producer of faux leather is China. This country also has the largest market for synthetic leather products, and it exports these products all over the world to consumers in Asia, Europe, South America, and North America.

As more nations reach first-world industrialization levels, the global demand for faux leather products is expected to increase accordingly.

The comparatively low price of synthetic leather compared to genuine leather continues to drive the popularity of faux leather in areas where poverty is common but inclement climatic conditions drive demand for weather-resistant textiles. Since synthetic leather is produced in a fabric form with no need for weaving, the cost of this textile is gauged in price per yard instead of price per pound.

While established types of faux leather, such as PU and PVC leather, usually cost less, novel forms of this fabric, such as vegetable oil-based leather, are significantly more expensive.

It may be possible to receive bulk discounts on large orders of faux leather. Each type of faux leather has different attributes, and each form of this synthetic substance is ideal for a particular application:. This material is the least expensive type of synthetic leather on the market.

Accordingly, it is less durable and comfortable than other types of faux leather. PVC leather is slightly more durable than PU leather, and it is also produced in greater quantities. Recently, manufacturers have started experimenting with vegetable oil leather.

In addition to being more environmentally friendly, vegetable oil leather also appears to be more durable than PU or PVC leather. Faux leather production has a generally negative impact on the environment. The production of the fossil fuel derivatives used in faux leather production, such as ethylene, inevitably introduces toxic substances into surrounding ecosystems, and petroleum is a limited resource that is only obtainable by drilling, which harms surrounding plant and animal life.

Since synthetic leather is not biodegradable, it remains in the environment once it is discarded. Since genuine leather biodegrades within a decade or two, the polluting power of fake leather is much greater than the real thing. Additionally, it bears considering that the majority of faux leather production takes place in China.

While third-world production of faux leather is inexpensive, it has a greater environmental impact. Vegetable-based faux leather theoretically has a reduced impact on the environment since it is biodegradable. However, the market share of vegetable-based synthetic leather is so small that the environmentally beneficial attributes of this fabric are all-but nonexistent.

At this point, there are no certifications available for faux leather fabric itself. Since this type of fabric cannot be recycled and even plant-based versions of synthetic leather go through significant chemical processing, it is not eligible for organic certification. However, the production processes used to make faux leather can be certified as environmentally-friendly.

For instance, some synthetic leather manufacturers are certified by The Greenguard Environmental Institute , which seeks to put environmentally-friendly standards in place for the production of synthetic fabrics and fibers.

In addition, it may be possible for synthetic leather producers to seek certification by Leadership in Energy and Environmental Design LEED , which is an independent organization that attempts to regulate production processes in a variety of industries. Individual synthetic leather manufacturers may also be able to produce certification proving that their products are genuine. About the author:.

Preparatory stages;. However, the operations the hide undergoes that could be anywhere from 35 to 55 different operations all depend on what type of leather a manufacturer is producing. Leather is traded internationally and comes in different conditions: fresh, wet salted, pickled, sun-dried, crust, wet blue, and finished. To make leather, here are the steps a manufacturer would need to follow:. At this stage, the manufacturer begins prepping the hides for tanning. The leather manufacturer begins neutralizing the acids left behind from tanning. Finally, the material passes through its final steps.

This outer layer will show natural scars and haircell patterns if left as uncorrected natural grain. The thickness can vary depending on the gauge set at the time of splitting and the application. Whether produced for Upholstery , Garment , Shoe or Saddlery , these are the best types of leather as they are the strongest and most durable and valuable layer of hide. After splitting to the required thickness, this natural grain is buffed or sanded and replaced with an embossed grain and finish to simulate various hair cell patterns. The resulting effect will look flawless with no natural scars showing, but this is no longer the real or natural grain.
