On December 5, 2025, Ningbo - The functional requirements of textile fabrics are upgrading from single waterproofing to multi-dimensional "waterproofing+wrinkle resistance+breathability". Ningbo Runhe High tech Materials Technology Co., Ltd. recently announced that its independently developed high viscosity low ammonia amino silicone oil (piperazine silicone oil) has officially entered mass production. This technology achieves synergistic improvement of fabric waterproofing and wrinkle resistance through molecular structure innovation, providing a new generation of solutions for high-end clothing, automotive interiors, and other fields.


Technical analysis: Dual advantages of low ammonia value and high viscosity
Traditional amino silicone oil is prone to yellowing under light or high temperature conditions due to its high ammonia value, and the resulting film layer has insufficient toughness, resulting in limited wrinkle resistance of the fabric. Runhe Material has developed a new type of silicone oil that combines chemical stability and film-forming properties by using a special modification process to reduce the ammonia value to below 0.1mmol/g and increase the viscosity to 5000-10000mPa · s.


The low ammonia value design makes silicone oil difficult to degrade in weak acid and weak alkali environments, while the high viscosity ensures that it forms a uniform and tough protective film on the surface of the fabric, "said the R&D manager of Runhe Materials


Application scenario: Cross border expansion from high-end ready to wear clothing to smart wearables
At present, this technology has been applied in multiple fields. A certain international fast fashion brand used Runhe silicone oil to treat its spring and summer series shirts. After improving the wrinkle resistance of the fabric, the frequency of ironing by consumers decreased by 70%, and the product return rate decreased by 15%; A certain automotive interior supplier in Shanghai has developed a waterproof and wrinkle resistant coating suitable for seat leather by adjusting the viscosity of silicone oil, which maintains stable performance in environments ranging from -30 ℃ to 80 ℃ and successfully enters the Tesla supply chain.


More noteworthy is that Runhe Materials is exploring the application of silicone oil in the field of intelligent textiles. By compounding with conductive fibers, the developed flexible silicone oil coating can endow the fabric with touch sensing function while maintaining waterproof and breathable properties, providing a more comfortable interactive experience for wearable devices.


Industry trend: Silicone oil technology drives the high-end transformation of the textile value chain
According to the China Fluorosilicone Organic Materials Industry Association, the market size of silicone oil in China is expected to exceed 8 billion yuan by 2025, with high value-added products accounting for over 35%. The innovative practice of Runhe Materials shows that silicone oil has been upgraded from a traditional fabric finishing agent to a functional platform material. Through molecular design and composite technology, multifunctional products such as anti-static, flame retardant, and temperature control can be derived.


In the next three years, we will focus on developing bio based silicone oil and biodegradable silicone oil to meet the new requirements of EU carbon tariffs and other regulations, "said the chairman of Runhe Materials." Through continuous technological iteration, silicone oil is expected to become a key enabler for the green transformation of the textile industry
