Estimating the term…
The present invention relates to a fibrous structure, being testable in a series of run-off tests, wherein each run-off test comprises exposing said fibrous structure to a volume of a test solution and said fibrous structure initially is hydrophobic and has been treated to be hydrophilic. wherein said fibrous structure exhibits a run-off level that is less than 5 percent by weight throughout a series of run-off tests, wherein the series starts with a first run-off test and ends with a fifth run-off test, use of said fibrous structure, tissue product and nonwoven material made of said fibrous structure. Further, it relates to an absorbent article comprising at least one of said fibrous structure and to use of said absorbent article.
A fibrous structure, being testable in a series of runoff tests, wherein each run-off test comprises exposing said fibrous structure to a volume of 25 ml of a test solution and said fibrous structure initially is hydrophobic and has been treated to be hydrophilic, characterized in that said fibrous structure exhibits a run-off level that is zero throughout a series of run-off tests, wherein the series starts with a first run-off test and ends with a fifth run-off test, and that said test solution has a surface tension before the first run~f test which is above 70*10−3 N/m and a surface tension after the first run-off test which is less than 60*10−3 N/m.
A fibrous structure according to anyone of the preceding claims, characterized in that said fibrous structure exhibits a predetermined degree of hydrophilicity which is substantially unaffected by wetting of said fibrous structure.
A fibrous structure having one or more types of polar, silicon-containing compounds bounded to at least one portion of the surface of the fibrous structure, characterized in that a surface active agent or a composition comprising a surface active agent, is added to said fibrous structure.
A fibrous structure according to anyone of the preceding claims, characterized in that it comprises one or more non-woven material.
Use of a fibrous structure according to any of the preceding claims for making tissue products.
