<p>PROBLEM TO BE SOLVED: To provide a material for treating the excretion of animals having high urine permeation. SOLUTION: A strip of paper 1 is twisted to form a twisted string 3 and the string is cut short and the resultant short-cut, twisted paper rods 13 are used as the objective excretion treatment material. In this case, the short-cut, twisted rod 13 is made in a paper layer structure S so that the paper fibers are directed from one cross section to the other cross section and the excretion including urine is permeated from the individual cross sections 13a, 13b along the paper layer structure S into the short-cut twisted paper rods 13.</p> |
