Blackout fabric and translucent fabric serve different light-control needs. A blackout roller blind is chosen to block light, while a translucent blind allows light through the fabric. When comparing coated fabrics, start with the required light-control effect, then consider the coating, surface finish, handle and fabrication method.
A functional coating adds a layer to a textile base to give it particular properties. The coating formulation and application process are therefore central to the finished fabric, whether the requirement is blackout, translucency, water resistance, a decorative finish or flame retardancy.
HOW A FABRIC COATING IS APPLIED:
Coating compounds can use water or solvent systems, with materials such as polyurethane, acrylic, PVC or PE. The compound is spread evenly over a cotton, polyester, nylon or other textile base using equipment such as a rotary screen, scraper or roller. Oven drying and curing form a uniform coating layer on the fabric surface.
COMMON FABRIC COATING TYPES:
PA or acrylic coating
PA coating is also described as AC or acrylic adhesive coating. It is a widely used finish that improves fabric handle, wind resistance and body.
PU coating
Polyurethane coating gives the fabric a fuller, more elastic handle and a film-like surface.
Down-proof coating
A down-proof finish helps prevent down from escaping through a fabric and is used for down jackets. PA coatings meeting particular water-pressure requirements are also described as down-proof coatings.
PA white coating
A layer of white acrylic resin improves coverage and reduces color show-through, helping fabric colors appear more vivid.
PU white coating
A white polyurethane resin coating serves a similar covering function. Compared with PA white coating, it gives a fuller handle, greater elasticity and better coating fastness.
PA silver coating
A silver-white coating adds shading and radiation-protection functions. Typical applications include curtains, tents and clothing.
PU silver coating
PU silver coating provides the basic functions of PA silver coating with better elasticity and coating fastness. It is also used for tents and other fabrics requiring higher water-pressure resistance.
Pearlescent coating
A pearlescent finish gives the fabric a pearl-like luster in silver or other colors. Both PA and PU pearlescent coatings are available. PU pearlescent coating produces a flatter, brighter surface with a stronger film-like appearance.
Flame-retardant coating
Flame-retardant coating is applied to ordinary fabric or flame-retardant cotton fabric to provide flame-retardant and waterproof effects.
COATED FABRIC APPLICATIONS:
Coated fabrics are used in sportswear, down jackets, rain parkas, coats, tents, footwear, curtains and bags. Waterproof and breathable finishes are also used for ski clothing, mountaineering suits and windbreakers. Other application fields include national defense, navigation, fishing, offshore wells and transportation.
CHOOSING A ROLLER BLIND FABRIC:
For a window-covering enquiry, specify whether the finished blind should provide blackout or a translucent effect. Include the window dimensions, desired color, fabric appearance, coating requirements and planned cutting method. Ask for a sample in the required finish so the appearance and handling can be reviewed with the intended blind construction.

FAQ
What is the difference between blackout and translucent fabric?
Blackout fabric is selected to block light, while translucent fabric allows light through. Decide the required light-control effect first, then compare the coating, surface finish and handle for your blind construction.
What do PA and PU mean in fabric coatings?
In the coating terminology used here, PA or AC refers to an acrylic coating, while PU refers to polyurethane. Acrylic coating improves body, handle and wind resistance. PU coating produces a fuller, more elastic handle and a film-like surface.
How do white, silver and pearlescent coatings differ?
White coatings improve coverage and reduce color show-through. Silver coatings add shading, while pearlescent coatings give the surface a decorative luster. PA and PU versions offer different handle, elasticity and coating-fastness characteristics, as described above.
What should a coated blackout fabric enquiry include?
Include the required blackout or translucent effect, finished blind dimensions, color, surface finish, coating requirements, cutting method and quantity. Send your roller blind fabric requirements to discuss a suitable material and sample.
