Abstract:

From the perspective of differential capillary effect and wetting yonsure effect, the principle of unidirectional water-transfer in textiles was reviewed. Manufacturing method of unidirectional water-transfer can be divided into chemical method and structural design method. The advantages and limitations of the methods were compared. The main influencing factors of water-transfer performance, namely, chemical factors and physical factors were also reviewed. By controlling these factors, excellent unidirectional water-transfer properties through the fabric thickness could bi achieved. The limitations of conventional testing method was discussed on water-transfer and through a nowel testing method (cimparatively-MMT) was introduced. The current problems in unidirectional water-transfer textiles are believed to be solved by the study of mechanism, preparation method and testing method. Finally, the practical applications of unidirectional water-transfer textiles were included.
