Optimizing the Original Touch and Enhancing the Core Advantages of Silk
Natural silk fabrics such as mulberry silk inherently possess a delicate and smooth quality. However, after post-processing such as dyeing and sand washing, fiber damage, a rougher feel, and a duller luster are easily encountered. The polar groups of organosilicon softeners can precisely adsorb onto the surface of silk fibroin fibers, forming an ultra-thin, flexible siloxane protective film. Without damaging the original natural luster of the silk, this further optimizes the fabric's smoothness and drape, restoring the soft, skin-friendly feel to the originally stiff sand-washed silk. Furthermore, by adjusting the type of auxiliaries, different styles can be customized: some can enhance the silk's cool, smooth drape, suitable for high-end formal fabrics; others can create a slightly velvety, supple feel, making everyday silk garments more warm and textured.
Repairing Fiber Damage and Improving Fabric Durability
Silk fibers are inherently delicate and fragile, easily prone to snagging, tearing, and pilling during daily wear and washing. After penetrating the tiny gaps in silk fibers, silicone softeners can repair and encapsulate damaged silk fibroin structures, increasing fiber toughness and tear resistance by over 20% and significantly reducing pilling and snagging during daily friction. Simultaneously, the stable silicone film reduces frictional wear between fibers. Even after multiple washes, silk fabrics won't quickly harden and become brittle like untreated fabrics, maintaining a soft and smooth feel for a long time and effectively extending the lifespan of expensive silk products.
Preserving Breathability While Meeting High-End Environmental Requirements
Unlike traditional, heavy softeners that clog the pores of silk fibers, the new generation of modified silicone softeners does not damage the porous structure of silk itself. The fabric's breathability and moisture absorption are virtually unaffected, retaining silk's core advantages of being cool and breathable in summer. Meanwhile, these low-yellowing, environmentally friendly silicone products fully comply with the OEKO-TEX 100 eco-textile standard, leaving no harmful residues on silk fabrics and not affecting the colorfastness of subsequent printing and dyeing. They perfectly meet the stringent processing requirements of high-end silk garments and home textiles, and are one of the most core functional additives in the current silk finishing process.
