Description

第1層10Aから第2層10Bへの汗の移行をより速やかに行うようにする観点からは、第2層10Bの繊維間距離は、第1層10Aの繊維間距離と同じかそれよりも短いことが好ましい。一般に、構成繊維の繊維距離が短いほど毛管力が強いところ、吸汗性シート10においては、着用者の肌から相対的に遠い側に位置する第2層10Bの繊維間距離を第1層10Aのそれよりも短くして相対的に毛管力を強力にすることで、汗の厚み方向における移行速度をより一層高めることが可能となる。
第1層10Aの繊維間距離と第2層10Bの繊維間距離との差は、前者−後者として、好ましくは5μm以上、さらに好ましくは15μm以上、そして、好ましくは35μm以下、さらに好ましくは30μm以下である。両者の繊維間距離の差が大きすぎると、第1層10Aでの毛管力の低下及び第2層10Bでの吸汗容量の減少により吸汗性能が低下するおそれがある。繊維間距離は、下記式(1)により求めることができる。
From the viewpoint of accelerating the transfer of sweat from the first layer 10A to the second layer 10B, the inter-fiber distance of the second layer 10B is equal to or greater than the inter-fiber distance of the first layer 10A. It is preferably short. Generally, the shorter the inter- fiber distance of the constituent fibers is, the stronger the capillary force is. Therefore, in the sweat absorbing sheet 10, the inter-fiber distance of the second layer 10B located relatively far from the wearer's skin is set to the first layer 10A. It is possible to further increase the transition speed of sweat in the thickness direction by making the capillary force shorter than that to make the capillary force relatively strong.
The difference between the inter-fiber distance of the first layer 10A and the inter-fiber distance of the second layer 10B is, as the former-the latter, preferably 5 μm or more, more preferably 15 μm or more, and preferably 35 μm or less, more preferably 30 μm or less. Is. If the difference between the two fiber distances is too large, there is a possibility that the sweat absorption performance may be deteriorated due to a decrease in the capillary force in the first layer 10A and a decrease in the sweat absorption capacity in the second layer 10B. The interfiber distance can be calculated by the following formula (1).
