Abstract

To provide a hand towel made of a compound type nonwoven fabric composed of wood pulp and a synthetic fiber, a hand towel which can materialize all features in which the towel has good water absorption, soft feeling, and non-stiff surface, in which the towel can be properly taken out piece by piece by a pulldown-type dispenser, and in which the towel is easy to crease by an inter-folder and multi-folder processor, with processing suitability excelling.SOLUTION: In a compound type nonwoven fabric hand towel, a pulp fiber web is laminated on a synthetic fiber and integrated. Basis weight of the pulp fiber portion is 30.0 g / m2 or more and 66.0 g / m2 or less. A difference of thickness between 3.7 KPa measurement and 50 KPa measurement is 50 μm or more and 160 μm or less. A dynamic friction coefficient for which the synthetic fiber surfaces are rubbed together in a withdrawal direction is 0.40 or more and 1.08 or less. A basis weight ratio of a pulp fiber / a synthetic fiber is 90 / 10 or more and 70 / 30 or less. The foregoing are characteristics of the hand towel.SELECTED DRAWING: Figure 1

Claims

1. A composite nonwoven fabric hand towel, in which a pulp fiber web is laminated and integrated onto synthetic fibers, The hand towel is made by folding the aforementioned composite nonwoven fabric into a V-shape using an interfolder or multifolder processing machine, so that when one towel is taken out, the next one comes out. The basis weight of the pulp fibers is 30.0 g / m². 2 66.0g / m or more 2 The following conditions apply: the difference between the 3.7 kPa measurement and the 50 kPa measurement of thickness is between 50 μm and 160 μm; the coefficient of dynamic friction when the synthetic fiber surfaces are rubbed together in the pulling direction is between 0.40 and 1.08; and the basis weight ratio of pulp fiber to synthetic fiber is between 90 / 10 and 70 / 30. A hand towel characterized in that, when a sample with the hand towel's pull-out direction as the longer side is measured using the Clark stiffness tester method, the protruding length is 65 mm or more and 95 mm or less.
