PVC coated fabrics have enhanced surface properties due to the polyvinyl chloride (PVC) coating, but their color stability is affected by several factors:
UV exposure: Prolonged exposure to sunlight can lead to coating aging and fading.
Contact with chemicals: Substances such as ink, oil stains, and bleach can corrode the coating and damage the pigment structure.
Friction and mechanical damage: Frequent friction or scratching with hard objects can wear down the coating, allowing the color of the underlying fabric to show through.
Improper cleaning: Using alkaline detergents or washing with hot water can cause the coating to peel off or change color.
Detergent selection: Use neutral detergents or special fabric cleaners; avoid bleach, strong acids, and strong alkalis.
Water temperature control: Hand wash or machine wash gently with warm water below 30℃; high temperatures will accelerate coating aging.
Stain removal tips: For oil stains, sprinkle a small amount of baking soda, let it sit, and then gently brush; ink stains can be treated locally with alcohol.
Avoid direct sunlight: After washing, dry in a cool, well-ventilated place, avoiding direct sunlight to prevent coating fading.
Mildew prevention: In humid areas, spray with an anti-mildew agent, or cover with white paper after drying to isolate moisture.
PVC coatings are sensitive to acids and alkalis; keep them away from fertilizers, cleaning agents, and other chemicals to prevent discoloration or peeling of the coating.
Usage scenarios: For tents and other items, regularly check the seams and avoid excessive friction that can cause coating wear.
Storage method: When folding, use a soft cloth as a cushion, and avoid heavy pressure or contact with rough surfaces. 3. UV Protection Treatment
Add a sun-protective coating: When purchasing, prioritize PVC fabrics containing UV stabilizers (such as UV-P), or apply a UV-protective spray afterwards.
Check the test report: Prioritize PVC coated fabrics with a color fastness level of 4 or higher (washable and abrasion-resistant).
Natural pigment coating: Some high-end products use natural pigments such as chlorophyll and lutein, resulting in a softer color change after fading.
Dry and sealed: Ensure the fabric is completely dry before storing. Fold it and place it in a moisture-proof bag, avoiding contact with metal parts.
Regular inspection: For long-term storage, take it out for ventilation every quarter to prevent mold and coating adhesion.
Maintaining the color of PVC coated fabrics requires attention throughout the entire process, from purchase and use to maintenance. Through scientific cleaning, environmental protection, and regular maintenance, its aesthetics and durability can be significantly extended.
