Classification by texture

Even carpets produced by the same manufacturing method will produce carpets with different appearance effects due to the influence of raw materials, pile form, pile height, feel, texture and density. Common carpet surface texture categories are:

1. plush carpet

This is the most common cut velvet carpet. The pile length is 5 ~ 10 mm, and a broken pile can appear on the carpet surface, which is flat and even.

2. Velvet carpet

The pile length is about 5mm, and the pile on the carpet surface is dense, which produces a velvet-like effect.

3. Saxony carpet

The length of the pile is about15 mm. After twisting and heat setting, the pile produces the effect similar to that of optical fiber, and the texture is full.

Coiling method

Check the carpet quality inspection report.

In the process of carpet production and processing, carpet adhesive and other manufacturing, the latex and various additives used will inevitably leave some harmful substances in the products, such as formaldehyde, styrene, 4- phenylcyclohexene and so on. When laid and used, it will bring some pollution to indoor space, and when used in children's rooms, it will bring great influence to children's health. Therefore, when purchasing carpets for children's rooms, you need to check the product quality report to see if it meets the national standards.

Carpet label is a mandatory standard in light industry. Carpet products sold in the market must be truly marked according to the requirements of carpet label: product name, registered trademark of the product, name and content of carpet fiber, fluff thickness of the carpet, quality grade of the product, production date of the product, name and address of the manufacturer, special performance requirements of the product and other information. You can get a general idea of carpet quality by looking at the label.

Identify product materials

In order to prevent the carpet material from being faked, especially when choosing pure wool carpet, it is necessary to identify the carpet material first. The general method is to take some wool from the carpet and identify it according to the burning situation and the smell after ignition. When pure wool burns, there is no flame, smoke, bubbles and peculiar smell, and the ash is mostly shiny black solid, which will be broken when the finger is gently pressed.

Check the appearance quality of carpet.

When choosing a carpet, consumers should check whether the carpet surface is flat, whether the edge of the carpet is straight, whether there are defects, oil stains, color differences and so on. Especially when buying tufted carpets, be sure to check whether the back of the carpet is off-line or seeping, so as to avoid bulging and inequality in the process of laying and using the carpet, thus losing the comfortable and beautiful effect.

Other quality inspection

Check whether the carpet feels comfortable; Check the pile density. You can touch the carpet with your hands. Its products have high plush quality and full carpet surface density. This kind of carpet has good elasticity, trampling resistance, wear resistance, comfort and durability. Check the color fastness of the carpet. When choosing a carpet, you can rub it repeatedly on the surface of the carpet by hand or try cloth to see if there is color on it. If there is color, it means that the color fastness of the product is not good. Check the peel strength of carpet backing. Gently tear off the base fabric by hand to see the degree of adhesion. If the adhesion is not high, the base fabric and carpet are easy to separate, so the carpet is not durable.

There are burnt marks on the carpet. If it is not serious, you can brush off the burnt part with a hard brush or nickel. If it is serious, put a book on it and comb it when it is dry.

Carpet and health

When people move into new houses, they often buy carpets to decorate their rooms. However, carpets have a subtle influence on people's health and are often unknown.

Carpet fabrics are easy to accumulate dust because of their thick latitude and longitude lines and large gaps. Trace dust escapes into the indoor air, polluting the clean air. After heating in the heating room in winter, these dust particles will change their original properties and become gaseous substances that are more harmful to human body.

In recent years, there has been a disease caused by carpets in Japan, and most of the patients are young children. Its main symptom is continuous fever, and the effect is not great after taking the medicine. Then the tongue swells and the hands peel off, which leads to death in severe cases.

This is caused by the microorganism "mite" that breeds in the carpet. This kind of microorganism feeds on cell fragments falling off human skin, and once it enters the lungs or bronchi, it will make people sick. Children have weak resistance and love to play on the carpet, so the prevalence rate is the highest.

Experts suggest that it is best not to cover the ground with a big carpet; The second is to use wooden floors to pave the floor together; The third is to spread the floor with floor leather; Fourth, put a rug in front of the bed and sofa.
