How to identify the authenticity of a silk carpet?
In this post, we are going to provide you with some information about some methods of testing the silk of a carpet. If you intend to buy a real or genuine silk carpet, knowing these methods can help you. These methods are very easy to use, therefore if you them, you can make sure that the carpet you are going to buy is made up of real silk.
Being familiar with texture of the silk, can make it easy for you to identify the real silk carpets. For this reason, we provide you with some brief information about silk before testing it. In fact, Silk is a natural protein fiber which is naturally obtained from silkworm cocoons. In other words, natural or real silk is composed mainly of proteins.
The real silk carpet
Today the so-called silk carpets are of different types; real/genuine and fake /synthetic carpets. Therefore, if you may know the methods of testing the silk of a carpet, you can distinguish the real silk from the synthetic one. The real silk carpet is made up of silkworm cocoons and is composed of around 90% silk. Accordingly, the process of silk production begins with extracting raw silk through cultivating the silkworms. After the worms become pupated in their cocoons, they are dissolved in boiling water. Then the produced fibers are extracted and fed into the spinning reel.
What is real silk carpet made of?
If you are looking for the methods of testing the authenticity of the silk, you should note that the material of which the real/genuine silk is made is totally different from the fake/synthetic one. Many of those who are familiar with these methods know that real silk is made up of natural materials. Real silk is a natural protein fiber which contains amino acids such as Alanine, Serine, Valine, Glycine, Tyrosine and Glutamate. In fact, natural silk has a special chemical formula called C15H23O6N5 and it can be easily identified using the silk testing methods in the labs.
Some methods of distinguishing the real silk from the fake one are as follows:
- The burning test
One of the methods of testing the silk is to burn it with a flame. This way, you can easily identify the real silk carpet. For this purpose, ask the salesman for permission to burn a carpet thread with a flame. When it is burnt, the real silk will create the smell of burnt hair. The reason is that both hair and genuine silk have similar textures and are both made up of protein. However, when the synthetic silk is burnt, it will turn into the soft and white ash and will create the smell of burnt paper.
- The touching test
Another method of testing the silk of a carpet is to touch and rub the silk with your hands. This is a very simple way to identify the real silk. Accordingly, it is enough to touch and rub the carpet for a short time. If you feel warm in the palm of your hand, it indicates that the silk of the carpet is natural. However if you do not feel warm, it shows that the silk is synthetic.
- The chemical test
One of the other methods of testing the silk of the carpet is to solve a small piece of it into a solution. For this purpose, at a room with the normal temperature, add 16 grams copper sulfate and 10 grams glycerin to 150 ml of water and then gradually add one tablespoon caustic soda into it. If it is dissolved in this solution, the silk is real, otherwise it is synthetic.
