PURPOSE:To provide the water-absorbable fiber web capable of being readily produced and dyed and exhibiting an excellent water-absorbing performance, an excellent absorbed water-evaporating performance and a soft touch. CONSTITUTION:The water-absorbable polyester fiber web is formed of side-by- side type conjugate hollow thick-thin fiber yarns comprising a polyester (component A) containing >=95wt.% of polyethylene terephthalate and a modified polyester (component B) having a larger alkali-mercerization rate than that of the component A and having a hollowness constant of 10-30%, thick parts and thin parts randomly existing in each filament constituting the yarns in the longitudinal direction of each filament and between the filaments, many traverse grooves extending in the direction rectangular to the axis of the filament and reaching the hollow part of the filament existing on the side of the component A of the thick parts, and longitudinal grooves extending in the axial direction of the filament and reaching the hollow part of the fiber existing on the side of the component B of the thick parts. |
