Design of silica coated polyamide fabrics for thermo-regulating textiles

Résumé

Efficient thermal management is essential for the energy balance and thermalcomfort. In this context, the design of textiles, which can modulate the infraredradiation emitted by the human body, is attractive. These fabrics will managethe microclimate between the skin and fabric. The proposed textile design con-sists of the coating of commercial woven fabrics based on polyamide 6–6byadip-coating process. The coating is based on the incorporation of fine sphericalsilica particles with a submicron size within thermosensitive poly(N-isopropy-lacrylamide) hydrogels. Neat commercial fabrics reflect 12% of the radiation,while the addition of silica particles leads to a reflection of 24% of the infraredradiation in the 5–15μm wavelengths range. The infrared radiation reflectioncapacity of the coated fabrics can be increased by managing the size and thecontent of the silica particles, which allows reaching 36% of reflected radiation.Our findings open opportunities for warming up fabrics and thus reduceenergy consumption in heating close space
