Product Series: High-Temperature Stable Amino Silicone Oil (for High-Temperature Setting)
Brand: Kefeng (Zhejiang Kefeng Silicone Co., Ltd.)
In the textile printing and dyeing industry, high-temperature setting processes (such as heat setting of polyester, nylon, or cotton fabrics, typically reaching 180-200°C) are critical for imparting dimensional stability and flatness to fabrics. However, this process poses severe challenges to softeners: conventional amino silicone oils are highly prone to oxidative yellowing and molecular chain scission at high temperatures, leading to stiff fabric hand feel, unpleasant odors, irreversible color change, or even silicone spots on the fabric surface caused by demulsification and oil spotting.
Since its establishment in 2002, Zhejiang Kefeng Silicone Co., Ltd. has been dedicated to the R&D and manufacturing of block silicone oils and various specialty silicone oils. It is now recognized as "the largest manufacturer of ternary block silicone oil in China", with a monthly production capacity of crude block silicone oil reaching 1,000 tons. Leveraging its strong R&D capabilities and deep understanding of textile fiber characteristics, Kefeng introduces the High-Temperature Stable Amino Silicone Oil. This product is not a simple modification of traditional amino silicone oils, but rather a solution that—through precise molecular structure design (low amine value / ternary block) and environmentally friendly processes—perfectly resolves the contradiction between "soft hand feel" and "heat resistance & anti-yellowing". It provides dyeing and finishing enterprises with an ideal softener applicable across pre-setting, mid-stage, and post-setting processes.
The primary reason conventional amino silicone oils yellow easily at high temperatures lies in their relatively high amine value (-NH₂ content) and linear homopolymer structure. Through years of technical accumulation, Kefeng has successfully developed low-amine-value ternary block copolymerization technology:
Low Amine Value Design: Precisely controls the quantity and distribution of amino groups on the silicone oil molecular chain. While retaining excellent fiber adsorption and soft hand feel, it significantly reduces the density of heat-oxidizable chromogenic groups. As a result, fabrics treated with this oil achieve whiteness retention of over 95% after setting at 180-200°C, completely eliminating the yellowing or graying issues associated with traditional silicone oils after baking.
Ternary Block Structure: Unlike conventional random or single-ended structures, Kefeng organically combines polyether segments, amino functional groups, and the silicone main chain in a block configuration. This structure not only imparts excellent self-emulsifying properties and stability, but also forms a three-dimensional molecular "cage" that effectively protects the easily oxidized amino groups, significantly enhancing overall heat resistance.
The value of Kefeng High-Temperature Stable Amino Silicone Oil lies in its comprehensive satisfaction of the core needs of dyeing and finishing enterprises:
Performance Dimension | Kefeng High-Temperature Stable Amino Silicone Oil | Conventional High-Ammonia Amino Silicone Oil |
|---|---|---|
High-Temperature Yellowing Resistance | Excellent (≥95% whiteness retention after 200℃ setting) | Poor (significant yellowing, graying) |
Hand Feel Style | Soft, smooth, fluffy – customizable | Soft but greasy or stiff |
Working Bath Stability | Excellent (shear-resistant, pH-stable, no demulsification) | Poor (oil spotting, roller sticking) |
Hydrophilicity | Engineerable (hydrophilic options available) | Poor (typically water-repellent) |
Environmental Compliance | Compliant (low VOC, biodegradable) | Some contain prohibited substances (e.g., APEO) |
2.1 Excellent Heat & Yellowing Resistance
Light-colored or white fabrics treated with Kefeng's high-temperature stable amino silicone oil retain their bright colors and high whiteness even after severe high-temperature setting, as well as subsequent heat treatments like calendering or foil stamping. This directly improves the first-quality product rate and reduces rework costs associated with yellowing.
2.2 Outstanding Working Bath Stability
In high-temperature, high-shear, wide-pH-range working baths, this product exhibits excellent emulsifying dispersibility and electrolyte tolerance. It does not demulsify, oil-spot, or stick to rollers, effectively avoiding the silicone spot defects and equipment cleaning difficulties caused by traditional silicone oils, thereby ensuring efficient and stable continuous production.
2.3 Full, Smooth, and Customizable Soft Hand Feel
Kefeng can provide different hand feel styles—softness-focused, smoothness-focused, or fluffiness-focused—according to customer requirements for different fibers (polyester, nylon, cotton, rayon, T/C blends, etc.). Its unique block structure allows uniform adsorption onto fiber surfaces, forming an elastic film that imparts a durable, dry, non-greasy, high-quality tactile experience.
2.4 Environmentally Friendly & Safe Compliance
As a company honored as a "Top 20 Enterprise with Comprehensive Strength of Textile Printing and Dyeing Auxiliaries in China", Kefeng's products strictly follow environmental trends. This high-temperature stable amino silicone oil is free of prohibited substances such as APEO and NPEO, has low VOC, and meets international eco-textile standards such as Oeko-Tex Standard 100.
Based on the company's stated focus on developing "targeted hydrophilic silicone oil for various fibers, achieving a perfect combination of hydrophilicity and hand feel," this high-temperature stable product is particularly suitable for the following scenarios:
Polyester & Nylon Fabric Heat Setting: Especially suitable for sportswear, outdoor gear, automotive interiors, and other fabrics requiring high lightfastness, heat-aging resistance, and a dry hand feel. For black polyester fabrics, Kefeng's "deepening resin and deepening silicone oil" technology can be combined with this product to achieve a 50-80% depth increase while maintaining softness.
Post-Finishing of Cotton & Rayon Knits: Using the hydrophilic grade of high-temperature stable amino silicone oil, it preserves or enhances the fabric's natural moisture absorption and wicking performance without sacrificing softness, meeting the comfort requirements of next-to-skin underwear and infant wear.
Polyester Microfiber & Silk-Like Fabrics: Provides an extremely fine, smooth, draping, silk-like hand feel while withstanding subsequent calendering or high-temperature baking.
Finishing of Package-Dyed Yarns & Loose Fibers: Good penetrability, uniform treatment, high-temperature drying resistance, and no yellowing risk.
In the era of slim margins in dyeing and finishing, any quality incident caused by poor auxiliaries stability leads to significant cost losses. Kefeng High-Temperature Stable Amino Silicone Oil relies on the company's three manufacturing bases, a registered capital of 60 million RMB, and a large-scale supply capacity of 1,000 tons per month to ensure long-term product quality stability and reliable, timely supply.
