High Value-added Warming Fibres with Mid-Infrared Reflection & Low Conductivity

This project develops warming fibres with improved textile warming effect by adding middle infrared (MIR) reflection function to filament yarns and enhancing the adhesion between aerogel fillers with matrix resins.

Existing nonwoven or staple yarn products for thermal insulation are incorporated with silica aerogel, a superlight material with high thermal insulation but being transparent to IR light. These aerogel products do not support strong adhesion with polyester and are not applicable in filament yarns so far. Also, the resultant textiles still have shortages, such as being volumetric and having obvious loss in strength. Considering two-third of heat loss from human body is caused by MIR radiation at a static situation, this new technique will evidently increase the warming effect of textiles made from filament yarns without significant loss of their strength. 


These filament yarns of MIR reflection will be directly made into warming fabrics via knitting or weaving, which are applicable to wide scope of products, including intimates or underwear, night wear, beddings, curtains, tents, winter garments, diving suits, etc. 

Technological Breakthrough
  1. Reduce the mass necessary for warm wearing in cold conditions, lowers the energy consumption of residence buildings and environmental impact of textile industry.
  2. Provide special protection for aging people who are suffering seasonal diseases especially in cold winter, reduces the expenditure of government on related medical services.
