In modern society, environmental pollution caused by decoration is becoming more and more serious. The serious consequences caused by indoor air pollution are indeed shocking. The main culprits of indoor air pollution are decoration materials, furniture, sanitary ware, etc.

However, there is another source of pollution that may not have aroused the vigilance of some people. It also deserves our great attention! That is the problem of carpet pollution.

Due to the general improvement of people's living standards, more and more families have adopted carpets as essential decorations for homes, offices and business rooms. However, carpets also have potential safety hazards in terms of environmental protection. Moreover, the air pollution caused by non-environmentally friendly carpets is no less than that of decoration materials and furniture.

First, learn about the classification of carpet craftsmanship from the professionals of Beijing carpet manufacturers.

Carpets are generally divided into hand-knotted carpets, hand-gun pierced carpets and woven carpets.

Hand-knotted carpets are made purely by hand, mostly pure wool and silk as materials, with pattern design, color matching, yarn dyeing, warping, hand knotting, flat carpets, blankets, carpet washing, cutting, trimming, etc. Processed and manufactured by processes. Dozens of colors can be harmoniously blended together. The compact and delicate surface of the carpet can extend the life of the carpet to decades or hundreds of years. Therefore, high-end handmade carpets are called soft gold, which are handicrafts and practical items with great collection value. . With the increase in labor costs, the value of handmade carpets will inevitably increase.

Such a cumbersome process makes it take a few months to a year or two to make a blanket.

The professional sales staff of the carpet manufacturer told us: It can be seen from the production process of the carpet that only the hand-knotted carpet is woven by hand from natural silk and wool. It does not contain any harmful chemicals, so only hand-knotted carpets are completely safe and environmentally friendly carpets. The gun-stabbed blanket must be coated with a thick layer of glue on the back to stick to the base fabric. Woven blankets are also inevitably exposed to the use of chemicals. In the production and processing, blanket back coating and other manufacturing processes, the latex and various compounding agents used will inevitably retain some harmful substances in the product, such as formaldehyde, styrene, 4-phenylcyclohexene, etc. These residual harmful substances exceed the mandatory standards promulgated by the state and will cause great harm to our bodies. In order to reduce production costs, many manufacturers use some low-quality glues, which makes it difficult for their products to meet environmental protection requirements. According to media reports, this happened in the US Environmental Protection Agency. More than 60 employees experienced headaches and dizziness, and more than 10 were hospitalized. It took a lot of effort to find that it was the carpet under their feet that was at fault. According to related reports, the random inspection of some large-scale woven carpet manufacturers by the relevant state departments shows that the environmental protection pass rate is indeed not optimistic!

The wool and silk must be distinguished carefully, especially for silk carpets. The quality of the silk directly affects the price and lifespan of the product.

The gun-stabbed carpet is made by piercing various colored threads with a hand-stabbing gun on a special fabric, then applying glue on the back of the carpet, attaching a base cloth, and wrapping it by hand. The materials include wool, wool plus a small amount of silk, polypropylene, nylon and so on. The pattern color can also reach more than ten or twenty kinds, the precision and the service life are less than that of a pure handmade blanket.

The preparation takes about a week or two.

The production method of woven carpet relies on today's advanced machinery and equipment, and the materials are mostly polypropylene, nylon and some wool. There is not much craft and artistic value. At present, the most advanced domestic weaving technology can make ten kinds of color configurations. Although the color pattern and service life cannot be compared with handmade carpets, the price is relatively low.
