7D virgin composite hollow fiber silicone oil High Loft Silky Smooth Filling Fiber for Toys Pillows Apparel

7D virgin composite hollow fiber silicone oil · 7D*32MM · Specifications can be customized

The 7D*32MM virgin silicone-coated composite hollow polyester staple fiber addresses long-standing pain points in the filling industry. Ordinary post-sprayed silicone fibers often suffer from uneven silicone distribution, oily spots, easy peeling and fiber migration, which cause prickly feel, fabric drilling, clumping after washing and inconsistent product quality.

This premium filling fiber solves these problems at the production source. The in-line silicone coating process applies silicone oil evenly and continuously onto the fiber surface during the spinning process, forming a firm, uniform lubricating layer that integrates with the fiber itself. Unlike post-sprayed silicone that easily flakes or washes off, this original coating remains stable through washing, extrusion and long-term use.

The single hollow composite structure creates abundant internal air cavities, giving the fiber outstanding bulkiness and thermal insulation. Compared with solid fibers of the same weight, it delivers over 30% higher loft and better warmth retention, allowing manufacturers to reduce material usage while maintaining the same plumpness and comfort.
