What is Recycled Leather? What kind of material is recycled leather?

Recycled leather process:

Dermal fibers, cross-linked fibers, resins and other additives are mixed first.

its technological process.

For: Raw leather or recycled leather is crushed into skin fibers of a certain size, and then it is combined with natural rubber.

resin and other raw materials, after mixing, compress them into filter cake; The filter cake is heated to melt the fibers on the surface to make it viscous, and each layer is extruded, bonded, dehydrated and formed, cool-dried, sliced, embossed and surface treated.

After getting the final product. Main features: Recycled leather has the characteristics of both genuine leather and PU, and is a very versatile leather fabric today.

Like leather, reclaimed leather has moisture absorption, air permeability, and good workmanship also has the same softness and elasticity as leather, light texture, strong resistance to extreme high and low temperatures, and wear-resistance. Its disadvantage is that the strength is inferior to the same thickness of leather, of course, it is also worse than PU, and it is not suitable for leather goods with greater force such as shoe uppers.

Because the production process of recycled leather is more flexible and can be adjusted in real time, by increasing the amount of natural latex and changing the process formula, a variety of products with different hardness and different strength can also be made to make up for her own shortcomings.

Its later surface treatment is similar to PU, and the regenerated leather is also a color in the surface texture and color, not only refurbished, but also new products emerge in an endless stream. What's more important is that she is very competitive, only one-tenth of the leather, three times the PU, very value-for-money, cost-effective.

The scraps of leather are processed into whole pieces of leather, which is called recycled leather.

Recycled leather manufacturing is simple:

1. Leather waste is torn and ground into fibers, and then pressed into sheets with adhesives such as natural latex and synthetic latex. It can be used instead of natural leather to make the insoles, main heels and toe of leather shoes, and can also be made into car seats, etc. The shape of recycled leather, just like pasta, can be made as you like.

Not only is it relatively strong, but it is also lightweight, heat-resistant, and corrosion-resistant.

2. The leftovers of leather can also be made into collagen paste mixed into leather. This kind of leather is inseparable from the real and fake natural leather. This leather has the excellent properties of natural leather and synthetic leather materials and is being widely used.

3. The leftovers of leather can also be made into foamed leather together with plastic. It has both the abrasion resistance of plastic, the elasticity of leather and good slip resistance, and is comfortable and firm to wear. It is calculated that if 10,000 tons of waste leather residue is used to make this leather, the amount of PVC resin that can be saved is equivalent to the output of a 3,000-ton PVC factory for three years.

4. Use the leftover materials of shoes, leather goods and tanneries, after material selection and pretreatment, crush into leather pulp, and then add a series of compounding agents such as latex, sulfur, accelerator, activator, etc., fully stir and disperse evenly, place it on the long net machine, and obtain the finished product through dehydration, drying, polishing and other processes. Recycled leather can be used as a material such as the main heel of leather shoes, insoles, visors and bicycle saddles.

Recycled leather is the use of tannery waste and scraps generated during the processing of leather goods.

Recycled leather, also known as candy paper, is mainly used for packaging paper, envelopes, paper bags, etc. and printing machine cylinder lining, etc., and is a commonly used auxiliary material in leather-related finished products such as leather goods, leather shoes, furniture, etc.

As an intermediate interlayer, recycled leather can present various performances and added value by replacing cardboard printing and PU composite processes with its high-quality texture, elasticity, toughness, moisture resistance and processing adaptability.

Lifted, and can be renamed leather, the profit increases. According to incomplete statistics, the monthly use of recycled leather in more than 50 containers, and this import figure with the rapid improvement of China's leather processing level is rising, has caused a shortage of supply.

Leather bran paper is also called recycled skin.

It is the use of leather waste and leather goods in the process of processing the corners of scraps, ** after processing into high value-added products.

It is an auxiliary material commonly used in leather-related products such as leather goods, leather shoes, furniture, etc., in Europe, the United States, South Korea and other advanced areas of the leather industry, reclaimed leather is an indispensable material for leather goods and leather shoes manufacturing plants, in the middle interlayer, recycled leather regenerates its unparalleled texture, elasticity, toughness, moisture resistance and processing adaptability to replace cardboard; In terms of fabrics, recycled leather can present various performance effects through embossing, printing and PU compounding, and is widely used in leather goods, furniture, book covers and other occasions. Although reclaimed leather is more expensive than cardboard, the production cost has risen slightly, but its products are high-quality, the added value has increased, and it can be called leather, and the profit has increased. The excellent performance of recycled leather is not only the choice of high-quality leather export processing plants, but also is being recognized and accepted by more and more domestic leather manufacturers who attach importance to quality, according to incomplete statistics, China currently imports more than 50 containers of recycled leather every month, about 700 tons, and this import figure is rising with the rapid improvement of China's leather processing level, which has caused a state of short supply.

1. Recycled leather is not genuine leather.

2. The reclaimed leather on the market is divided into three kinds: natural leather, regenerated leather and artificial leather, and regenerated leather is made by crushing Daxinhui leather or regenerated leather raw materials into leather rolling fiber and natural rubber, resin and other raw materials, which are often used to make leather goods, leather shoes, and home furnishings. Recycled leather has good moisture absorption and breathability, and at the same time, it is affordable and popular with Tanshi people.

Recycled leather is not genuine leather. The recycled leather on the market is divided into three types: natural leather, regenerated leather, and artificial leather, and recycled leather is made by crushing genuine leather or regenerated leather raw materials into leather fibers and natural rubber, resin and other raw materials, which are often used to make leather goods, leather shoes, and home furnishings. Recycled leather has good moisture absorption and air permeability, and at the same time, it is affordable and popular.

Recycled leather is not genuine leather.

Now there are three categories of leather on the market, namely natural leather (leather), regenerated leather, artificial leather Xiaochun, regenerated leather has the characteristics of both genuine leather and PU leather, is the leather or recycled leather raw materials crushed into a certain size of leather fiber, and then mixed with natural rubber, resin and other raw materials, and then made by special technology.

Recycled leather is the use of tannery waste and leather goods in the process of processing the corners of the jujube materials, ** after processing into high value-added products, often used in leather goods, leather shoes, home and other leather products in life, is a more universal auxiliary material.

Properties of recycled leather

Like leather, recycled leather has excellent moisture absorption and air permeability, and also has the characteristics of softness, elasticity, high and low temperature resistance, and wear resistance, but its strength is much smaller than that of leather of the same thickness, and it cannot be used to make items with greater bearing capacity. The production process of recycled leather is more flexible, it can adjust the thickness, hardness and so on according to the actual situation, and it is to use different strength changes to meet the actual needs of the body, and its best affordability is only one-tenth of the leather.

1. Recycled leather is not genuine leather.

2. The reclaimed leather on the market is divided into three types: natural leather, regenerated leather and artificial leather, and regenerated leather is a mixture of raw materials such as leather or regenerated leather into leather fibers and raw materials such as natural Zheng brother rubber and resin, which are often used to make leather goods, leather shoes, and home furnishings. Recycled leather has good hygroscopicity and air permeability, and is popular with people.

First, the materials are different.

1. Regenerated leather is to crush genuine leather or regenerated leather raw materials into leather fibers of a certain size, and then mix them with natural rubber, resin and other raw materials, and compress them into filter cakesThe filter cake is heated to melt the fibers on the surface to make it viscous, and the layers are extruded, bonded, dehydrated and formed, dried, sliced, embossed and surface treated to obtain the final product.

2. In China, people are accustomed to calling the artificial leather produced with PVC resin as raw material as PVC artificial leather (referred to as artificial leather), the artificial leather produced with PU resin as raw material is called PU artificial leather (referred to as PU leather), and the artificial leather produced with PU resin and non-woven fabric as raw materials is called PU synthetic leather (referred to as synthetic leather).

3. Genuine leather is made of animal skin, which is conceptually relative to artificial leather made of chemical fiber materials.

Recycled leather is a commonly used auxiliary material in leather-related finished products such as leather goods, leather shoes, and furniture. Recycled leather, also known as leather bran paper, is the use of leather waste and leather goods processing process generated by the scraps, in Europe, the United States, South Korea and other advanced areas of the leather industry, reclaimed leather is an indispensable material for leather goods, leather shoes manufacturing plants, in the middle of the interlayer, reclaimed leather with its unparalleled texture, elasticity, toughness, moisture resistance and processing adaptability to replace cardboard. <
