Complications of using foam products (synthetic leather)

After the stone and the skin, genuine leather can be considered as the oldest thing that human have had. Since a long time ago, leather has been as the cover for early humans and even, today it is so. Leather is still popular among many global communities. But why should not we use foam products ( synthetic leather )?

 

Years before the creation of the fashion industry, genuine leather was used to make clothes and accessories, This matter is seen in all ages and all cultures, Complications of using foam products (synthetic leather)
This product protects the human body as well as the various items. In addition, leather is a comfortable and durable material.
Today, a variety of leather is available to human. Many people spend their time producing leather goods. No product is comparable with handmade leather good.
Complications of using foam products (synthetic leather)
Now we consider the question which says why we should not use foam products (synthetic leather) and then we discuss the complications of using this product.
The foam does not have any breathing properties for our skin.
It does not smell like genuine leather (due to the use of chemicals and complete synthetic materials in foam)
Foam is not durable like natural leather (leather has a very high rigidity, so that it can be used for towing a car)
It can not be used as a dress for a long time, because wearing it directly, is harmful to the skin.
Compare with a leather coat, foam is not a good insulation against cold.
After a while it will be rotted and easily damaged (leather has a very long life, so that a natural leather bag can be used for many years, as well as along with firmness, longevity and credibility and attractiveness, leather bags can make humans more esteemed.
The appearance of the foam is very unnatural and artificial.
Complications of using foam products (synthetic leather)
Wearing foam products (synthetic leather) is not healthy for a long time, especially in the hot seasons, wearing foam-made shoes is harmful to the skin because of its unhealthy materials and it leads to skin problems.
Its softness cannot be like sheepskin leather.
Its shininess is not as much as leather, (such as Burnish leather).
It cannot have the natural beauty of leather.
Foam has very limited elastic properties.
Wearing products made of foam (synthetic leather) is not as comfortable as genuine leather.
In the hot seasons, wearing shoes made of foam (synthetic leather) is harmful to the skin of feet because of the possibility of harmful substances causing skin problems.
But the main question here is why should we really use leather (genuine leather)?
Firstly, leather is a kind of natural fiber completely.
As you sweat with your skin, animals also sweat, so it can be concluded that leather has very good ventilation, especially in the shoes, and also absorbs transpiration. You can use leather in different thicknesses and for various applications. You can have a very soft wallet of goat or a firm and rugged of cow.
Although cowhide can be thin and soft like skin of goat, meanwhile the leather is also used as a luxury and precious item that you can buy in a variety of different sets.
The leather has a very high rigidity so that it can be used for towing a car. The leather is resistant to direct fire heat and it does not inflame. Leather has a very long life, so that a leather bag can be used for many years. Also, along with firmness, longevity and credibility and attractiveness, leather bags can make humans more esteemed.
Today, a variety of leather is available to humans. Many people spend their time for making leather goods. No product can be comparable with handmade leather good.
General factors affecting skin and leather quality

General factors affecting skin and leather quality

Leather quality and skin quality

Livestock development projects in many parts of the world have a positive impact on the Leather quality and skin quality. In many developing countries, the livestock breeding system is weak, and it produces small, often damaged skin.

A. Skin quality
1. Geographic environmental or climatic factors

The skin of the livestock is completely subjected to environmental conditions and climate change has a direct impact on its quality.

In drought situations or unsuitable climatic conditions, due to the lack of suitable pasture, livestock must travel a long way for feeding, but naturally it leads to the skin damage because of the collision with a variety of barriers and thorns, as well as the long way and the melting of fat under the skin of the animal.

2 . Decrements of skin quality – due to external factors:

2-1-decrements before slaughtering – such as stroke and scratches due to livestock collision to wood, inaccuracy in wool, picking and injuries caused by scissor, and branding them to identify them.

2-2– Slaughter decrements – such as inaccuracy in peeling the skin and the lack of other methods of peeling, using bad knife which causes the skin to rub, tear, and make holes on the skin. Tired cattle slaughtering, bad degreasing…

2-3- Decrements resulted from incomplete drying and bad keeping of the skin – The removed skins will decay due to the lack of acceleration in collection, washing, salting, drying completely in the shade, or due to using bad methods in storing and…

3. Defects in skin quality caused by parasites and infectious diseases

These defects are mainly due to lack of adequate hygiene at the site of livestock storage, high humidity, lack of light and bad nutrition, and so on.

4 . Skin that are of dead animals.

These skins are often rough and are damaged by a lot of injuries in the grain.

5 . And non-industrial slaughtering in house.

In some cases the bought sheep and goats are slaughtered at home and this leads to injuries, and because of lack of full knowledge of the intermediaries during transportation to the leather factories, the skin will get many injuries (such as skin decay)

6. social-cultural factors

In third world countries, due to some reforms and development such as the development of cities, roads, factories, cultivated fields, etc., pastures (especially first-class pasture), which are the main source of livestock food, have been destroyed.

In this regard, it has negative qualitative and quantitative effects on the quality of skin production.

7. Technical factors

Livestock development projects in many parts of the world have a positive impact on the quality and quantity of the skin. In many developing countries, the livestock breeding system is weak, and it produces small, often damaged skin.

Lack of technical knowledge of livestock breeders in the proper use of pastures, livestock breeding, feeding with hand forage, livestock health, lack of livestock specialists in the governmental sector and non-technical and unprincipled management, implementation of personal ideas and taste.

The lack of extensive research centers for livestock and related industries according to weather and different races are among the factors affecting on decrease of skin quality.

8 . Financial and planning factors

The comprehensive growth of the leather sector requires coordinated efforts to finance the development and retrieval system of large and small raw skin and expand the capacity of leather and leather products.

Governments play an important role in the development of the leather industry by investing in their own industrial and commercial policies, but the lack of corresponding efforts for key investments in improving the supply of raw leather is quite obvious.

9. Price

One of the factors in the supply of many goods is their price. But in the case of skin it is not seen as severe. The main reason is that manufacturers consider the skin as a subsidiary of their main activity (meat production)

In fact, the skin value is about 5% of the slaughterhouse income. Of course, the idea that a higher quality of skin will bring more income for the rancher will not have an adequate impact on the improvement of livestock breeding and slaughtering.

Of course, some of the deficiencies may be reduced in mass slaughtering, but in the case of non-mass slaughtering, this would be ineffective and would require a culture of collective benefit not individual benefit.

10. Natural factors

The way of breeding and nutrition, climatic conditions, pastures, drought, livestock hygiene and … are among the natural factors affecting the quality and quantity of skin.

Low quality of pastures (especially in developing countries) Long-term droughts (especially in Africa) losses in livestock production, lack of proper nutrition in cold seasons (especially due to lack of forage, livestock breeding, etc.) have a significant impact on livestock in skin production decrees.

Low of adequate forage in pastures, which are the main source of livestock nutrition, and continuous and increasing poor nutrition over the years.

in addition to reducing the production of livestock products, has created an inappropriate physical-chemical environment for genes (factors transferring inheritance features), and it leads to transfer livestock products decrease as an inheritance to next generation.

11 .Lack of convenient communication lines facilities.

Especially in developing countries between the city and the countryside, it causes some of the skin gets decay until it reaches sales centers.

In most developing countries, due to the use of inappropriate means of transport such as camels, mules, cattle cart and rural boats, there is a great deal of damage to the skin.

this matters also show the impact of infrastructure activities on accelerating development activities. Especially economic-commercial.

Livestock development projects in many parts of the world have a positive impact on the Leather quality and skin quality.

 

B. leather quality
In terms of improving the quality of leather goods, some factors are obvious that we are going to mention some of them.

1.The existence of a strategy, together with a specific policy and planning for the optimum use of all resources, including human, material, informational and financial, which guarantees any kind of activity, either in terms of production or service.

Because if the goals and plans are clear, they lead to learning precisely and preventing the loss of energy.

2. Training of skilled and expert forces, including managerial, masters and operational courses. In order to obtain high-quality products, the knowledge of that industry is needed, and without any people who meet these conditions, progress in the production of quality leather will be impossible.

3. Access to raw materials with suitable quality – It is certain that the quality of leather produced depends on the type and quality of the raw material used and, if suitable raw material are given to leather manufactures, the products such as leather, will have high quality, otherwise, the progress of the leather industry and the production of a high quality product will not be significant.

4 .The use of new machines and their methods of implementation – The factories need to have more precision in production grows every day, and these centers must provide the highest precision in order to meet the demands of consumers.

Of course, only carefulness alone and access to advanced and precise machines will not be able to meet such demands. But a combination of the two that can work and bring technological advancement along with increased quality.
