How to prevent the surface coating of High precision blackout curtains fabric from falling off due to washing?

The surface coating of High Precision Blackout Curtains Fabric is the key to its light-shielding performance, but in daily use, cleaning and maintenance may cause the coating to fall off or be damaged. To avoid this, measures need to be taken from multiple aspects such as material selection, cleaning method and maintenance method. The following is a detailed solution:

Select high-quality coating materials
Coating material selection
PVC coating
PVC coating has good waterproof and light-shielding properties, but poor flexibility and is prone to cracking or peeling after frequent cleaning. It is recommended to choose a modified flexible PVC coating.
TPU (thermoplastic polyurethane) coating
TPU coating is softer and more durable than PVC, with excellent wear resistance and anti-aging properties, suitable for scenes that require frequent cleaning.
Polyester film coating
Polyester film coating is thin and not easy to fall off, suitable for occasions with high requirements for light-shielding effect.
Multi-layer composite structure
High-quality blackout curtain fabrics usually adopt a multi-layer composite structure, such as:
Inner layer: base fabric (such as polyester fiber).
Middle layer: light-shielding coating (such as TPU or polyester film).
Outer layer: protective layer (such as anti-scratch coating).
This structure can effectively protect the coating and reduce damage caused by washing.
Correct washing method
Hand washing is better than machine washing
The coating of blackout curtain fabric is easily pulled and rubbed by mechanical force during machine washing, which causes it to fall off. Therefore, it is recommended to give priority to hand washing.
If machine washing is necessary, please select the "gentle mode" and use a laundry bag to protect the curtain fabric.
Mild detergent
Use neutral or weak alkaline detergents and avoid strong acidic or alkaline detergents, as these chemicals may corrode the coating.
Do not use cleaning products containing bleach or strong decontamination ingredients.

Low temperature water washing
Use cold or warm water (no more than 30°C) when washing to prevent high temperature from damaging the coating.
Avoid soaking the curtain fabric for a long time to prevent the coating from absorbing water and swelling or falling off.
Avoid rubbing and wringing
During the washing process, avoid rubbing or wringing the curtain fabric vigorously, which may cause the coating to crack or peel off.
You can squeeze out excess water by pressing gently, and then lay it flat to dry.
Scientific drying and drying
Avoid direct sunlight
When drying, avoid exposing the curtain fabric directly to sunlight, because ultraviolet rays may accelerate the aging and shedding of the coating.
It is recommended to dry in a cool and ventilated place, or use the low temperature mode of the dryer.
Natural air drying
Natural air drying is the best choice to avoid damage to the coating by high temperature.
If you need to dry quickly, you can use a fan to assist, but do not use hot air.
Daily maintenance and care
Regular dust removal
Before washing, you can use a soft brush or vacuum cleaner to remove dust and dirt on the surface of the curtain fabric to reduce the frequency of cleaning.
Regular dust removal can also prevent stains from penetrating into the coating and extend its service life.
Local cleaning
For small stains, you can choose local cleaning instead of cleaning the whole piece. For example, use a damp cloth with a small amount of neutral detergent to gently wipe the stained area.
Avoid contact with sharp objects
When installing, removing or storing curtain fabrics, avoid sharp objects scratching the coating surface.
When storing, it is recommended to fold the curtain fabric neatly and place it in a dry, dust-free environment.

By following the above suggestions, you can effectively extend the service life of the curtain fabric while maintaining its excellent light-blocking performance and aesthetics. If you are not sure how to clean or maintain it, it is recommended to consult a professional or refer to the product manual to ensure proper operation.
