What are the characteristics of regular blackout curtain fabric in terms of durability and shading?

Regular blackout curtain fabric has the following characteristics in terms of durability and blackout:

1、 Light blocking characteristics
Light blocking is one of the core functions of Regular blackout curtain fabric, designed to effectively block external light from entering the room and provide users with a good sleeping or viewing environment.
High shading rate
This type of curtain usually adopts a multi-layer composite structure, such as adding a black shading coating (such as PVC, PE coating) on the base fabric, or using high-density woven polyester fibers, so that the fabric itself has a shading effect of up to 95% to 100%, which can effectively block sunlight and light.
Attention should be paid to the issue of edge light leakage
Although the fabric itself has good shading performance, if the installation between the curtains and windows is not tight enough, or the track/hook design is unreasonable, the phenomenon of "edge leakage" may still occur. Therefore, in practical applications, it is recommended to pair with blackout curtain heads or side sealing strips to enhance the overall blackout effect.
The shading performance is affected by the thickness and structure of the material
The thicker the fabric and the tighter the weaving, the better the shading performance. Meanwhile, the quality of the coating also directly affects the shading effect. High quality products will use a uniform and strong adhesion coating to avoid detachment due to washing or prolonged use.
Detectable shading performance
Professional shading rate testers can be used for measurement, and some countries and regions (such as ASTM in the United States and EN standards in Europe) have also developed relevant grading standards to evaluate the shading level of different curtain products.
2、 Durability characteristics
Durability determines the service life and cost-effectiveness of Regular blackout curtain fabric, mainly reflected in the following aspects:

Material selection determines durability
Most blackout curtains use polyester as the substrate due to its excellent wear resistance, tensile strength, and dimensional stability. Compared to natural fibers such as cotton, polyester is less prone to deformation, pilling, or fading, making it suitable for long-term use.
Coating affects lifespan
If there is a PVC or PE coating on the surface of the curtain, its adhesion strength directly affects its service life. High quality coatings will not easily peel off, while inferior coatings may crack or peel off within months, leading to a decrease in shading performance.

Strong UV resistance and antioxidant capacity
High quality blackout curtain fabrics are usually treated with UV resistance to reduce fabric aging caused by sunlight exposure and extend their service life, making them particularly suitable for rooms with direct sunlight.
Different washability performances
There are significant differences in the washability of products from different brands and processes. Some curtains support machine washing, but frequent washing may cause coating wear or shrinkage; Others suggest dry cleaning or partial cleaning. When making a purchase, you should check the label instructions to understand the cleaning method.
Good wrinkle resistance and resilience
Polyester material blackout curtains generally have good wrinkle resistance, and are not easily wrinkled when hung, maintaining a clean appearance.
The fire and flame retardant performance depends on the requirements
The blackout curtains used in public places such as hotels, cinemas, and conference rooms usually require additional flame retardant treatment to meet fire safety requirements. Household curtains should be selected based on their needs to determine whether they have this function.

In terms of shading: Regular blackout curtain fabric has excellent shading ability, with a shading rate of over 95%, especially suitable for places with high requirements for light control such as bedrooms, audio-visual rooms, hotel rooms, etc.
In terms of durability, polyester based blackout curtains have strong wear resistance, UV resistance, and good wrinkle resistance, but the quality of the coating and cleaning method can affect their service life.
