Phase Change Thermostatic Fiber 2D*25mm, Soft Silicon Oil Treated Fiber for Warm Clothing Filling Pillow & Home textile filling
Our 2D*25mm Phase Change Energy Storage Silicon Oil Treated Staple Fiber is a high-performance functional textile fiber that combines PCM intelligent temperature control technology with professional silicon oil finishing. This advanced material integrates constant temperature regulation, smooth processing, soft comfort, and durable performance, making it an ideal raw material for high-end all-season textiles.
- Phase Change Energy Storage: Built-in PCM components intelligently respond to temperature changes, absorbing heat in warm conditions and releasing stored heat in cold weather
- Silicon Oil Surface Treatment: High-quality treatment reduces friction between fibers, preventing tangling, knotting, and static electricity
- Optimal Dimensions: 2D fine denier design with 25mm standard length for superior softness and elasticity
- Durability: Maintains excellent bulkiness and resilience even after long-term compression and repeated washing
- Skin-Friendly: Hypoallergenic with pure raw material formula, safe for infants and sensitive skin

Embedded with high-performance phase change materials, the fiber actively absorbs excess heat when ambient temperature rises and releases stored heat when it gets cold. Maintains comfortable constant temperature range all day long, realizing warm in winter and cool in summer effect.
Professional silicon oil finishing delivers ultra-lubricious surface. Effectively reduces friction between filaments, prevents tangling, knotting and static generation. Improves production efficiency with smoother equipment operation.
2D fine denier structure brings tender, cloud-like soft touch and outstanding bulkiness. Features strong resilience, not easy to flatten or collapse after long-term compression. Maintains full and fluffy shape permanently.
Silicon oil coating provides stable anti-static property. Prevents sticking together or static electricity generation during spinning, carding and filling processes. Finished textiles stay neat and comfortable without static cling.
Low thermal shrinkage rate ensures stable size after processing and washing. Fiber will not deform, shrink or warp, maintaining original appearance and performance for longer service life.
