Is the sunshade toxic?
Whether using the cheapest indoor sunshade cloth, sunshade and thermal insulation blinds, thick coated sunshade curtains, or outdoor awnings and umbrellas of different grades, they are all ideal solutions for shading rooms. However, through testing, the sunshade cloth has problems such as excessive formaldehyde.
There are mainly four kinds of materials for the blackout cloth:
Light shielding coated flocking cloth, silver coated light shielding cloth, pure woven light shielding cloth and base cloth plus PVC composite cloth. The unqualified products are all made of light shielding coated flocking cloth. This kind of light shielding cloth is coated with a thick light shielding resin layer on the gray cloth, and a layer of flannel is added to the resin layer. The flocking cloth with light shielding coating has good hand feel and light shielding effect, but it is easy to have the problem of formaldehyde content exceeding the standard after coating and finishing. The coating also emits a pungent smell under strong sunlight.
Why does the new curtain hide the "formaldehyde killer"?
According to experts, in order to improve the wrinkle resistance, water and fire resistance, pressure resistance and color fastness of the fabric, some manufacturers often add artificial resin and other commonly used additives to the fabric. In the process of dyeing and finishing, various dyes, auxiliaries and finishing agents should be added, which may contain formaldehyde. After the curtain cloth leaves the factory, formaldehyde remains.
Environmental protection testing agencies remind new home decorators that they should also be environmentally conscious when purchasing curtains. Although cheap, it is difficult to ensure safety. It is recommended to buy pure woven blackout cloth with black silk in the middle. This product is not easy to produce formaldehyde problems, and is a green and environment-friendly sunscreen.
