Composite leather what is it: the process of creating the material, comparison with classic genuine leather

The use of composite leather is growing in popularity as consumers search for alternatives to real leather. For those who prefer the texture and appearance of leather but not all of its disadvantages, this material offers a distinctive combination of properties.

To create a material that resembles the texture and appearance of real leather, natural and synthetic materials are combined during the composite leather-making process. This creative method offers more design and application flexibility.

There are some similarities and differences between real leather and composite leather. Knowing these will enable you to select the material that best meets your requirements.

Description

One kind of material created from leftovers from the leather industry is called composition leather. Garbage can include scraps, animal skin trimmings, chrome shavings, and waste dust. Old leather goods are also appropriate, excluding raw hides and worn-out shoes.

To gather the waste into a single piece of fabric and then sew a boot or bag out of it, specific binding fibers such as polyester, polyamide, or polyethylene are needed. After melting, they are heated and fused together. Synthetic thermoplastic resins are utilized as the third constituent. They provide strength to the pressed leather’s fibrous structure.

Manufacturing process

The production of composite leather involves the application of various technologies:

• Pressing method without the use of adhesives. In this case, small pieces are dipped in hot water to warm up, then rolled into solid sheets. Sheets are easily processed to obtain a suede, metallized or embossed surface.
• Connection of waste with adhesives.
• Grinding of residues on a granulator, adding synthetic binding fibers, thermoplastic resins and other additives to the resulting mass. Formation of flat sheets, their drying, pressing under heating. During the last process, the resin melts and impregnates the fibrous structure of the fabric with it. If necessary, the cooled sheets are subjected to various types of finishing.

In comparison to the most recent advancements in leatherette, some experts believe the resultant material—also known as recycled leather—to be even more hazardous.

A composite material consists of multiple layers, or splits. They are joined by glue, replicated using fabric reinforcement, or impregnated with polymers. Untreated split leather is nearly impossible to use in the production of leather goods.

Particular organic materials will be required if the composite fabric is constructed from leather fibers, which can be synthetic, natural, or artificial.

The recycled version is made from pieces that vary in size and is produced using both natural and synthetic rubber latexes.

Whichever manufacturing technology is used, the end product is a thin, soft, non-woven material that resembles leather and is frequently coated on the front with polyvinyl chloride or another polymer.

Properties

The appearance of composite leather is very close to that of natural leather. It does not appear to be made from fully processed animal skins, but rather from natural raw materials. Despite being simple to polish, varnish, and paint, the material lacks several natural analogue qualities.

• low air permeability due to the resins used, as well as gluing and pressing procedures;
• insufficient strength, especially at temperatures below -15°C;
• water resistance;
• inelasticity;
• impracticality;
• short life.

However, low-cost items composed of pressed material are in high demand.

Difference from genuine

You must be able to tell the difference between these two materials if you want to avoid purchasing anything made of composite leather at the cost of its natural equivalent. Examining a portion of the material used to make the product is essential. The stretched skin’s appearance suggests that it is natural, and the diamond-shaped structure suggests an analog.

Composite leather warning signs include:

• symmetrical arrangement of pores on the skin pattern, their identical shape and depth;
• low elasticity;
• smooth reverse side, although sometimes the manufacturer glues suede to the reverse side;
• unpleasant chemical smell;
• uniformity of coloring;
• smooth even edge, from which fibers often stick out;
• shiny or dull uniform surface;
• a rough to the touch material with many creases;
• even on new shoes the leather cracks, which reduces their service life;
• the cut is almost identical to natural samples;
• weak combustion without smoke, accompanied by a faint smell of burnt horn with the formation of a fragile-looking residue with a hard sintered core.

Vital. To ensure that the customer is informed about how to properly care for the product and does not feel misled, a legitimate manufacturer will identify "K KOZHA" as the material used to make shoes or accessories.

Application

Composite leather is used to make cuffs, seals, and other technical items. In the shoe industry, it is used as a raw material but not as the primary component. It’s used to make the backs, soles, and insoles of shoes and boots. As a result, the finished product is less expensive while still having excellent performance qualities.

Upholstered furniture is upholstered with fabrics that have been recycled. Companions are other kinds of fabrics that are used concurrently. They are employed in the production of low-cost accessories like notebooks, covers, cases, document bags, and diaries. Using the embossing technique, products can have a variety of inscriptions and symbols applied to them.

Composite leather in shoes

Shoes made by manufacturers attempt to avoid using composite leather as their sole material.

There are various causes:

• It will not warm you in winter.
• It cannot be worn in the rain, and also cannot be worn on rough terrain.
• It will not last long, will quickly become covered with folds and wrinkles, will form creases at the bends, although the price is not much cheaper than products made of genuine leather.

The shoes’ hygienic condition will be violated due to low moisture exchange and air permeability. It will be uncomfortable and damp on feet, preventing skin from breathing. However, a variety of bacteria and fungi flourish in a humid anaerobic environment.

Composition leather for bags

Pressed material is used for interior trim and for the handles of bags and suitcases. A bag composed entirely of composite leather looks good and is nearly identical to a bag made of real leather. It can last for a while if used carefully. The most important thing is to keep it from freezing or getting wet. However, it is preferable to not rely on the product’s durability. It will eventually get cracked and wrinkled in ways that are hard to cover up.

Care

Materials such as composition leather are not resistant to severe frosts. It splits, explodes, and develops a web of wrinkles and creases. Such fabric boots will quickly sag from their original shape. Summer shoes will have the same effect in the heat. Although the glued material is impermeable to air, moisture eventually manages to seep through.

Suggestions. The care instructions are based on the characteristics of composite leather. Its suitcases and bags are resistant to frost and bad weather. For them, temperatures below -15°C are lethal. For shoes made from waste, the same guidelines hold true. It needs to be shielded from abrasions and cuts. Avoid cleaning with abrasives. Avoid exposing it to substances that contain chlorine. Use a damp sponge to remove stubborn dirt.

Press-pressed shoes will perform well only in dry, moderately-heated weather. It is best to dry wet boots in a warm area away from heaters.

Real leather fibers are bonded to a synthetic backing to create composite leather, a contemporary and environmentally friendly substitute for traditional genuine leather. It is less expensive and has a smaller environmental effect than real leather, but it still has a similar appearance and feel. Composite leather is more popular in fashion and upholstery because it is more adaptable, easier to work with, and comes in a wider variety of colors and textures—even though it might not be as durable as traditional leather.

Reviews

Like the majority of impoverished students, my goal was to kill all the "hares" in one purchase. Thus, a new bag needs to be affordable, fashionable, useful, and appropriate for every occasion. For the most part, the pressed leather option worked well. However, I most likely won’t dare purchase boots made of comparable materials. It is preferable to put money aside and purchase pricey, dependable, and thus long-lasting ones."

"I purchased cheap winter boots. I was told by the seller that they were made of real leather. But they broke less than a month later. The vendor misled. The fabric was, as it turned out, glued together piece by piece, which is why it fell apart. It is necessary to examine the composition more closely.

"A three-year-old glued leather wallet truly justified every ruble it cost."

"I can speak from personal experience because I used to be a shoe store salesperson. In actuality, composite leather is referred to as a canvas that is unfit for use in the production of leather goods. It’s not leather, but it’s also not leatherette. The material is not stretchable or able to breathe. Costlier than leatherette, but only suitable for a single season. Unless worn extremely carefully, then no more than two. Thus, you purchase intrigue rather than shoes when you purchase boots from "K KOZHI." Take caution.

Compared to traditional genuine leather, composite leather is more adaptable and environmentally friendly. For those looking for eco-friendly options, it is appealing because it uses fewer materials derived from animals but still has the look and feel of natural leather.

Combining synthetic fibers with leftover leather to create composite leather produces a sturdy material that is frequently simpler to work with and maintain. This makes it a sensible option for many uses, such as upholstery and fashion.

Composite leather balances appearance, usability, and environmental consciousness, even though it might not perfectly match the characteristics of real leather. Many see it as a positive development in ethical material sourcing that doesn’t compromise on performance or style.
