How PCM Cool-Touch Finishing Fabric Works?
PCM Cool-Touch Finishing Fabric is produced by applying microencapsulated phase change material — composed of advanced alkane compounds — onto fabric surfaces through a padding finishing process. The microcapsules are engineered with a 28°C phase transition point, closely aligned with skin surface temperature. When body heat causes the surrounding temperature to rise above this threshold, the microcapsules absorb heat energy by converting from solid to liquid state, storing it as latent energy within the capsule wall. As temperature falls, the process reverses — microcapsules re-solidify and release the stored thermal energy back toward the skin. This passive, self-regulating cycle operates continuously without any external power, providing measurable cool-touch sensation and thermal buffering at the fabric surface level.

Instant Cool-Touch Performance
PCM Cool-Touch Finishing Fabric achieves a contact cooling coefficient (qmax) exceeding 0.18 J/cm²·s under standard finishing dosage, with high-dosage applications reaching above 0.30 J/cm²·s, verified per GB/T 35263-2017. The result is a consistent, skin-perceptible cooling sensation upon contact — without relying on moisture evaporation.
Precise 28°C Thermal Buffering
The PCM microcapsules are calibrated to a 28°C phase transition temperature, responding directly to skin-level heat. PCM Cool-Touch Finishing Fabric moderates surface temperature fluctuations, reducing heat buildup during activity and maintaining a more stable microclimate against the skin.
PCM Cool-Touch Finishing Fabric Applications
PCM Cool-Touch Finishing Fabric brings temperature-regulating comfort to a broad range of everyday and performance textile products. Its finishing-based process makes it well-suited for innerwear, sleepwear, bed sheets, and pillowcases where cool-touch sensation directly enhances sleep quality and daily comfort. Beyond home textiles, PCM Cool-Touch Finishing Fabric is applicable to casual summer apparel, light activewear, and functional workwear — anywhere consistent thermal buffering at skin level adds measurable value. For brands seeking an entry point into smart temperature regulation without the cost premium of fiber-level PCM technology, PCM Cool-Touch Finishing Fabric offers a scalable and versatile solution.
