The main purpose of curtains is to regulate sunlight and improve privacy. Blackout is the undisputed champion of these two functions. The main feature of blackout fabric is its room darkening ability.

　　When purchasing power outages, we will encounter various terms; heat insulation shading cloth, woven shading cloth, shading cloth that can be used as a lining. White blackout curtain fabric, two-layer and three-layer fabric. None of them are cheap, so here is a guide on how to choose the type of blackout and what to expect for that particular fabric.

　　Curtains and curtains

　　Although there are many articles and textile definitions to distinguish curtains and curtains; on the basis of lining, light transmission is strong. We will simply imply that curtains can be used for curtains and curtain stitching fabrics just like a piece of fabric.

　　When people think of blackout curtains, the image of dark, heavy curtains comes to mind. Although this is correct, it is not necessary. Blackout curtains are available in white and light colors, and are as light as translucent curtains.

　　There are two production methods for shading fabrics:

　　1. Shading woven fabric

　　2. Thermal insulation fabric

　　Each has its own advantages, types and application methods.

　　Blackout woven fabric

　　These are densely woven fabrics; these fabrics are produced using weaving technology without any additional post-processing to increase the shading ability of the fabric. These are the commonly used and common forms of power outages on the market. These fabrics will attenuate of the light, so they are also called Dimout fabrics. These fabrics obtain light-shielding properties from their special structure; superimposed yarn arrangement or multi-layer fabric technology.

　　The fabric is multi-layered and therefore heavier. Satin is the way to produce dense woven fabrics, so satin exists on at least one side of the fabric.

　　Insulation shading cloth

　　These are coated fabrics; these fabrics feature a black acrylic foam backing on the fabric to block light. This is an additional treatment after processing the fabric. It is available in "2 pass" and "3 pass". In the second coat, a layer of black is applied to the fabric, and then a layer of white is applied. Therefore, sometimes the black layer can be seen from the front. The 3 coats have a white layer applied to the main fabric, the back of which is again supported by the black and white layers.

　　Black acrylic foam is used as an insulating material, so it is a heat-insulating and light-shielding fabric.

　　Compare

　　Knitting blackout is budget friendly.

　　White is only suitable for thermal insulation products.

　　Woven shading offers a variety of color ranges and customized printing.

　　Insulating block lights are better than woven shading lights.

　　The drape of the woven shading fabric is very good.

　　These fabrics can be used directly or as a lining.

　　Woven shading panels have a relatively low carbon footprint and are easy to recycle.

　　Maintenance (washing care) weaving shading is much easier.

　　In conclusion:

　　The blackout woven fabric is the clear winner. But for those of us who are willing to spend money on white hoods or those who need thin fabrics to make roller blinds, thermal hoods are your only choice.
