As we all know, picking the house is the preferred orientation, and the good lighting is a big advantage of the house, but the glaring sun has become the most headache for many citizens. How to resist the glare of the sun in your bedroom? Picking a suitable blackout curtain has become the first of many citizens.

Whether the curtains are shaded to see the density

In the Nancheng building materials market in Dongguan, in some curtain shops, the reporter found that the types of curtains are various, and the materials and prices used are also uneven. The materials are cotton, blended, fluffy, nylon, and the price ranges from 20 yuan to 250 yuan per meter. With so many types, how should we choose? For the effect of shading and heat insulation, many merchants recommend a curtain made of special shade cloth.

The price of such blackout curtains ranges from 20 yuan to more than 100 yuan per meter. Merchants told reporters that this blackout curtain is a lower price in the curtains. A clerk pointed to a curtain and told reporters, "The fabric of this curtain is designed for glare, and the opacity can reach more than 90%." The merchant pointed to several other curtains to tell reporters, like blended cotton. Hemp, the shading effect can only reach about 70%.

How to distinguish the shading effect of the curtain? Is the thicker the curtain shading effect better? The owner of a curtain shop told the reporter that the shading effect of the curtain is not seen from the thickness of the curtain, but from the curtain fabric. Knitting density. He pointed to a curtain and told reporters that the curtain was made of flannel, and it felt very thick when touched, but in fact it had a general shading effect. Another curtain, he told reporters, this curtain is made of nylon, the knitting density is very high, reaching 48,000 needles, which is the best curtain on the market.

No curtains with a 100% shading rate

The reporter found in the building materials market that some merchants claimed that the shading rate of the blackout curtains sold reached 100%. The so-called one hundred percent shading should be to put down the curtains in the sun, and the room will not reach out. Is this really true? Xiong Peng, the owner of a curtain shop in Gaosheng Home Furnishings, told reporters, "If a business says that the shading rate of its curtains is 100%, it must be a lie to you."

He said that the shade ratio of any curtain is less than 100%. The easiest way to verify is to blind the blinds to the outside sun. Only when you can't see the light at all is 100% shading. And this 100% shading can not be done on the curtains, only through the curtain wall, such as the curtain wall around the cinema. As for how to distinguish the shading of curtains, the advice given by the industry is: "It is the simplest and most effective way to select the shading cloth with good effect and look at the light or the sun."

Inferior blackout curtain toluene is easy to exceed the standard

For blackout curtains, many people questioned that although the shading effect is better than other curtains, they do not know whether they contain chemical or toxic components. In the interview, the reporter learned that the current blackout curtains on the market can be mainly divided into three types. One is to attach an additional curtain to the outside of the ordinary and beautiful curtains, which is generally coated. Due to the use of glue, it is necessary to do It is almost impossible to be completely non-toxic, and some have a more irritating smell. The other is to sandwich a layer of black raw material between the two layers of light-colored yarns, so that you can make different colors and patterns in the light and light colors, and absorb the incident light. There is also a curtain that relies solely on the density of the knit to achieve a blackout effect. This kind of curtain is the most environmentally friendly and is the most expensive on the market.

Yang Xiaoyan, the manager of Zhida Home Furnishing Nancheng Store, told reporters that at present, most of the blackout curtains at prices of 20 to 30 yuan per meter use chemical layers to achieve the shading effect. Still others, because there is no high-density process, high-density shading is achieved by crushing the rags and then bonding them together by glue. "The curtains are exposed to sunlight during the use of sunlight. The toxic components contained in the curtains are released for a long time, which is harmful to the human body." She advised the public not to buy such low-cost blackout curtains.
