Abstract

L'invention concerne un matériau d'absorption du sang (54) obtenu, soit en mélangeant une résine absorbant l'eau (58) avec une poudre fine (57), en déposant la poudre fine (57) sur la surface de la résine absorbant l'eau (58) après que la résine (58) ait été mouillée, puis en séchant la substance obtenue, soit en déposant la poudre fine (57) sur la résine (58), tout en mouillant ladite résine (58), puis en la séchant. Ce matériau présente un excellent pouvoir d'absorption du sang et des propriétés de rétention dues à la poudre fine (57) et peut empêcher la surface de la résine (58) d'absorber l'humidité de l'air. Un agent absorbant du sang renfermant un tel matériau d'absorption du sang (54) est utilisé pour des serviettes hygiéniques ou analogues et n'absorbe pas l'humidité de l'air, ou bien est utilisé sur une surface du corps pour garantir ses caractéristiques d'absorption d'eau initiales.
