Overview of External Silk Oil
External Silk Oil is a specialized protective coating formulated to provide exceptional durability, weather resistance, and aesthetic enhancement for silk-based textiles and outdoor materials. Engineered with advanced silicone-based compounds and eco-friendly additives, this oil penetrates fibrous structures to form a flexible, invisible barrier against moisture, UV radiation, and environmental pollutants. Ideal for silk fabrics, luxury apparel, and high-end decorative items, it preserves the natural luster and softness of silk while extending its service life under demanding conditions. Tested to meet international textile care standards, External Silk Oil combines effortless application with long-term performance, making it a sustainable solution for preserving delicate materials without compromising their tactile or visual qualities .
Key Features of External Silk Oil
-
Weather and UV Resistance – Protects silk from sun exposure, rain, and temperature fluctuations (-20°C to 60°C), preventing color fading and fiber degradation .
-
Non-Toxic and Eco-Safe – Free from hazardous chemicals; uses biodegradable ingredients compliant with global environmental and textile safety standards .
-
Water Repellency – Forms a hydrophobic layer that resists moisture absorption, reducing risks of mold, mildew, and staining .
-
Enhanced Durability – Reinforces silk fibers to resist abrasion and mechanical stress, ideal for frequently used items like upholstery or outdoor garments .
-
Easy Application – Can be applied via spraying, brushing, or immersion without specialized equipment. Dries quickly without residual stickiness .
-
Color and Gloss Retention – Maintains the vibrant appearance and natural sheen of silk by preventing oxidative damage and pollutant adhesion .
Typical Applications
-
Luxury Textile Preservation – Shields silk garments, scarves, and tapestries from humidity, dust, and UV damage .
-
Museum and Archive Conservation – Prevents microbial growth and insect damage in stored silk artifacts .
-
Outdoor Silk Decor – Protects silk-based outdoor furnishings (e.g., cushions, umbrellas) from weather-induced wear .
-
Automotive and Aviation Interiors – Enhances durability of silk upholstery in high-use environments .
-
