HOYU Textile and UC BACON co-developed a graphene printing fabrics for enhancing the thermal comfort
- How does the graphene apply in the application of functioanl textile?
Graphene is a nanomaterial with excellent thermal properties - the highest thermal conductivity of 5300 W/m‧k among all materials and more than 0.93 of thermal radiation emissivity - that make it a wonderful material for heat dissipation with the synergy of conduction and radiation effects.Therefore, Utilizing graphene’s superior thermal property to develop textile with thermal comfort is a hot topic recently. Graphene could be doped in fiber or coated on the surface of cloth to generate heat conduction channel and thus increase the heat transfer capability and efficiency of the cloth. With appropriate design of fabrics, the garments could generate longtime cooling or fast warming effect to regulate the body surface temperature to be uniform and steady, and thus could increase the comfortability of dressing substantially.
- The idea came up from HOYU and UC :
What if we adjust the feeling of cooling or warming by graphene, how does it improve the thermal comfort to wearing ?
HOYU Textile and UC Bacon co-developed a graphene printing fabric for enhancing the wearing comfort, and the goal is aiming the ultimate demand for long-lasting cooling and rapid warming up. UC provides high quality graphene with low impurity and no heavy metal that conforms the regulation of textile industry. Also, UC has devepoled a graphene suspension for the processing requirement of HOYU using a unique dispersion technique. It can be adjusted the graphene content and their rheology to fulfill the diverse demands of coating resin. With a proper design in texture of fabric from HOYU, the final function on thermal comfort for graphene printing textile could be enhanced obviously.
- How to convince our brand cutomer :
To choose and define a proper method for certification - ASTM D1518
Using the standard test module on the convection behavior of fabric developed by UC under the standard od ASTM D1518, we found the graphene printing fabric could have a obvious long-lasting cooling effect with a Qmax value of 0.24, 20% increasing for convection of heat, and at least 2 hours prolonged for cooling times. More detailed information are shown in the picture below.
In the other hand, with the same coating process on a porous structure of fabric, we found graphene printing fabric could have a obvious rapid warming up effect with clo value of 5, 10% increasing on insulation, and 3 times reduced for the warming time. More detailed information are shown in the picture below.
