The heat and water vapour transfer of PES fabrics in comparison to fabrics from different raw materials

The heat and water vapour resistances are important parameters related to the human thermal comfort. The knitted fabrics used for the production of next-to-skin wear are in contact with the human skin and therefore it is important for them to achieve optimal comfort sensation. The investigation has been carried out on the fabrics made of polyester, cotton, cotton/modal and viscose. The fabrics are mostly used for the production of next-to-skin knitwear. The fabrics have been designed to have similar construction parameters, while the raw material has been changed. The main purpose of the study is to evaluate the heat and water vapour resistance of polyester knitted fabrics and compare it to the resistances of polyester with profiled cross section. The intention is to place those values into the context of other fabrics. The results have indicated that the use of polyester with profiled cross section should decrease the transfer of heat and water vapour through knitted fabrics, while the knitwear produced from viscose should enable the highest rate of transfer.
