In the textile dyeing and finishing industry, achieving deeper, fuller, and brighter colors in medium and dark shade fabrics, such as black, navy, and red, has always been a challenge. Increasing dye dosage often leads to higher costs, reduced fastness, and color inconsistency.
To address these issues, deepening finishing technology has become a preferred solution. Among various options, deepening silicone oil is recognized as one of the most efficient auxiliaries for enhancing dyeing depth while maintaining fabric quality and eco-friendliness.
What is Deepening Silicone Oil?
Deepening silicone oil is a specialized textile finishing agent designed to enhance the visual depth, brightness, and richness of colors in fabrics, especially in medium and dark shades such as black, navy, and red.
Unlike conventional silicone softeners, which primarily focus on improving fabric softness, deepening silicone oil also modifies the optical properties of fabrics. Forming a thin transparent layer on fiber surfaces, it makes colors appear darker, fuller, and more saturated without the need for excessive dyes.
It is widely applied in the finishing of cotton, polyester, viscose, Modal, Tencel, and their blends, and is valued by textile mills and brands aiming to achieve premium visual effects in high-end garments.
How Does Deepening Silicone Oil Work?
The effectiveness of deepening silicone oil comes from its optical and physical modification of fabric surfaces:
- Transparent Film Formation
A thin polymer film is deposited on the fabric surface, changing how light interacts with the fiber. - Optical Deepening Effect
The film reduces diffuse reflection and increases light absorption, making fabric shades appear 10–30% deeper and brighter. - Improved Hand Feel
At the same time, the polymer layer provides fabrics with a soft, smooth, and elastic handle, suitable for high-end applications. - Durability & Stability
The effect remains stable under high temperature, pH variations, and repeated washing, and it features strong anti-yellowing performance.
Through this mechanism, deepening silicone oil achieves both visual enhancement and tactile improvement, delivering fabrics with a higher-quality appearance.
Core Advantages of Deepening Silicone Oil
- Obviously improves depth. Improves 20~30% dyeing depth on medium and dark color fabrics. Saves dyes and makes color darker and brighter.
- Superior Fabric Handle. Imparts fabrics dark-color visual effect and also provides a soft, smooth, and elastic handle.
- Environmentally-friendly. Contains no APEO or prohibited substance. Consistent with Oeko-Tex Standard 100 and international environmental protection standards. Meets the demand of Europe, America and Southeast Asia markets for sustainable products.
- Wide application processes. It can be used in the padding process and the exhaust process. Suitable for processing knitted and woven fabrics and high-end ready-made garments.
Recommended Application Processes
Proses pelapisan:
- Light and thin fabrics: 10~20 g/L
- Heavy and thick fabrics: 20~30 g/L
- Proses: Dipping and padding twice → Drying →Stentering (160~170℃ ×60~90s)
Exhaust process:
- Dosage: 1.0~3.0% (o.w.f)
- Bath ratio: 1:20
- Proses: 40~50℃ ×10~20 min→Dewater→Drying (100~120℃)
