从China供应商批发进口Anti Yellowing Agent — FOB条款

This anti yellowing agent (HT-2191) is a phenolic yellowing resistant agent specifically formulated for nylon fibres, supplied by HT Fine Chemical Co, Ltd. from their facility in Qingyuan, Guangdong Province, China. Its main composition consists of special surfactant derivatives, appearing as a yellow transparent viscous liquid with anionic ionicity and a pH range of 6-8. The product demonstrates stability against acid, electrolytes and mild alkali conditions, and dissolves readily in water for straightforward processing.

The agent works by efficiently preventing storage yellowing that occurs when white or pale nylon fibre contacts BHT (butylated hydroxytoluene), an antioxidant compound prevalent in most plastic packaging bags. This phenolic yellowing mechanism is a well-documented issue in textile finishing, particularly for nylon 6 and nylon 6,6 substrates that are susceptible to discoloration during storage and transit. The product is compatible with both padding and exhaust dyeing processes, and can be combined with bleaching agents in the same bath or applied post-dyeing at 70 degrees Celsius.

Primary applications include textile mills and dye houses processing white and pale shade nylon fabrics, yarns and garments where colour stability during storage is critical. Typical dosing ranges from 20-40 grams per litre for padding applications down to 2-4 percent on weight of fibre for dipping processes, with citric acid as a synergistic auxiliary. The standard packaging is 125 kilogram polyethylene drums with a six-month shelf life in sealed containers at room temperature.
