Y-Warm is a polymer-based nano closed-cell flexible thermal insulation material developed for use in apparel, footwear, ourdoor gears, automotive interiors, highspeed train interior, and other applications requiring insulation.[1] Its working temperature ranges from -50°C to 150°C.[1][2] Y-Warm does not rely on thick and bulky layers, such as fibres and foam. It is a flexible nanoporous materials instead of being brittle.[3][4] Its fabric-like insulation combines durability with high insulation performance.[2]
Technology
Structure and morphology
The material consists of closed micro-pores (30–190 μm) separated by nano walls (20–280 nm).[5] Its closed-cell ratio exceeds 95%, and its void rate surpasses 96%.[5] From a porous materials perspective, closed-cell structures generally perform better at thermal insulation than open-cell structures, and smaller pores tend to have superior insulation performance compared to larger ones.[6] Y-Warm has an areal density of 42.4 g/m2 and a thickness of 0.70 mm.[7]
Thermal insulation mechanism
The thermal insulation of Y-Warm relies on its closed-pore surface structure, which effectively reduces heat conduction.[7] The thermal conductivity of Y-Warm is 0.0224 W/(m⋅K), primarily due to the large number of closed pores on its surface.[7] Y-Warm's rough micro-porous surface has low reflectivity and an emissivity above 0.9, which provides far-infrared radiant properties.[8][7]
Moisture permeability and quick drying
Y-Warm has hydrophilic molecular structures, which allow moisture generated during physical activity to be absorbed and released efficiently.[9]
Antibacterial function
Y-Warm achieves top-tier (5A) antibacterial performance that inhibits the growth and proliferation of microorganisms.[10] The extent and durability of antibacterial performance are evaluated at Antimicrobial activity (Level AAA).[11]
Manufacturing and environmental properties
Y-Warm is manufactured through a water-based process, and the manufacturer reports that no volatile organic compounds (VOCs) are detected.[12] Y-Warm complies with EU SVHC safety standards covering 249 substances, and contains no PFAS or toxic substances, which is a safety guarantee for application in textile and garment.[13][14]
Lineup
Y-Warm is manufactured in five principal specifications.[15]
| Specification | Thickness / (mm) | Weight / (g/m²) | Approximate Increase in Perceived Temperature / (°C) | Application |
|---|---|---|---|---|
| YW-01 | 0.7 ± 0.1 | 46 | +10 | For apparel and gloves requiring softness |
| YW-02 | 0.9 ± 0.1 | 53 | +15 | For footwear, headwear, and insulated bags |
| YW-03 | 0.5 ± 0.1 | 38 | +6 | Used in combination with YW-01 for soft-feel areas such as cuffs |
| YW-04 | 1.0 ± 0.1 | 70 | +17 | Higher warp and weft tensile strength alongside insulation |
| FR-02 | 0.9 ± 0.1 | Flame-retardant grade meeting the requirements for automotive interior insulation | ||
History
- Y-Warm was developed over eight years of research and development.[4]
- In 2026, Yang Qiurong stood out with her collection, "State". She combined Y-Warm insulation technology with innovative knit structures, delivering garments that balance warmth with a clean, modern aesthetic.[17] By combining Y-Warm thermal insulation material with knitted fabrics, she won the Silver Award in the Creative Track at the 2026 graduation fashion week of the Beijing Institute of Fashion Technology.[18]
Application
- Columbia Men Black Omni-Shield Ascender II Softshell Gloves reportedly uses Y-Warm as the insulation layer.[19]
- Scientists introduced the concept of aerogel functional units and apply aerogel-functionalized textile coatings (AFTC) to closed-pore flexible polyethylene terephthalate (PET) based thermal insulation textiles (Y-Warm) as the substrate, addressing the inherent brittleness and poor processability result in suboptimal performance in personal thermal management (PTM).[7]
