Abstract: PROBLEM TO BE SOLVED: To provide a nonwoven fabric compound material of high moisture absorption, using a nonwoven fabric including inorganic fine particles, as a moisture-imparting material, having high moisture absorbing properties and having large moisture adjusting performance in the change of the degree of moisture, the nonwoven fabric having a capacity of holding a large amount of the fine particles among fibers. SOLUTION: The inorganic fine particles have a difference of moisture contents of 20-100% when determined at 20 deg.C and a relative moisture of 90%, and at 20 deg.C and a relative moisture of 65%. The inorganic fine particles are added to a nonwoven fabric at a ratio of 30-500 wt.% based on the weight of fiber of the nonwoven fabric. Further, inorganic fine particles having fine pore volume of 0.3-3.0 ml/g are added to a nonwoven fabric at a ratio of 30-500 wt.% based on the weight of fiber of the nonwoven fabric.

Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing in high productivity the subject combined filament yarn intended for giving fabrics of excellent touch without the need of using any self-elongative filament yarn. SOLUTION: The subject combined filament yarn comprises high-elongation yarn and low-elongation yarn; wherein the high-elongation yarn consists of a sheath/core conjugate yarn composed of a polyester as the sheath and, as the core, a polymer higher in the temperature dependency of tensile viscosity than the above polyester, while the low-elongation yarn consists singly of a polyester yarn. This method for producing the above combined filament yarn comprises the following process: at least two kinds of polymers corresponding to the high-elongation yarn and the low-elongation yarn are issued (melt-spun) from an identical spinneret into an indrawn heteroelongative combined filament yarn finished with >=0.1 wt.% of a non-polyether-based lubricant, which is subsequently drawn at a draw ratio 0.40-0.50 time the breaking draw ratio of the filament yarn with the highest elongation at 90-110 deg.C followed by heat-setting the thus drawn filament yarn at 110-130 deg.C.
