Abstract
The invention relates to polyolefin materials, in particular fibers, and/or filaments, and/or nonwovens, and/or nonwoven products made from at least one polyolefin and a melt additive containing a fatty acid ester, wherein a subsequent activation of the fatty acid ester contained in the melt additive occurs on the surface of the polyolefin materials by applying a formulation, which contains a silicone compound and a quaternary ammonium compound.
Claims14
Hydrophilic polyolefin materials, made from a mixture of at least one polyolefin and at least one melt additive containing a fatty acid ester of the general formula
- R—CO—O—CH2—CH2—O—R′,
- where R is a straight-chain or branched-chain alkyl residue with 23 to 35 carbon atoms, and where
- R′═H, —CH3, —C2H5, —C3H7, —C4H9,
- wherein the polyolefin materials include a subsequent activation of the fatty acid ester contained in the melt additive on the surface of the polyolefin material by applying a surface active substance in the form of a formulation which contains a silicone compound and a quaternary ammonium compound.
(canceled)
Method of producing hydrophilic polyolefin materials which consist of at least one polyolefin and a melt additive containing a fatty acid ester, wherein the polyolefin materials include a subsequent activation of the fatty acid ester contained in the melt additive on the fiber surface by applying a surface-active substance in the form of a formulation, which contains a silicone compound and a quaternary ammonium compound.
