COMPOSITION FOR PERMANENTLY HYDROPHILIZING POLYOLEFIN FIBERS AND USE THEREOF

摘要

The invention relates to a composition for permanently hydrophilizing polyolefin fibers and polyolefin filaments as well as nonwoven textile fabrics made thereof for use as hygiene products such as baby diapers and sanitary napkins or medicinal products such as incontinence products, wound dressings and surgical covers.;The composition contains a combination of a non-ionic surfactant, a cationic quaternary ammonium compound and a neutralized phosphoric acid ester. The fiber products finished with the composition exhibit improved resistance to wet migration and dry migration and quick fluid absorption.

主权项

1. A composition for permanently hydrophilizing polyolefin fibers and filaments as well as nonwoven textile products made thereof, comprising
(A) 15 to 50% by weight of at least one non-ionic surfactant, wherein the non-ionic surfactant is a compound selected from the group consisting of: alkoxylated C6-C18 fatty alcohols, alkoxylated C6-C18 amines, alkoxylated C6-C18 amides, alkoxylated C6-C18 fatty acids, alkoxylated C6-C18 fatty acid esters and alkoxylated C8-C18 alkylphenols, and wherein the non-ionic surfactant has one or more branched or straight-chain, saturated or unsaturated C6-C18 hydrocarbon chain; (B) 15 to 50% by weight of at least one quaternary ammonium compound of the general formula (I):
[R1—C(═O)—X—(CH2)n—NR2R3—(CH2)m—X—C(═O)—R1]+Y−  (I) wherein R1 is an alkyl group having 1 to 22 C atoms or an alkenyl group having 2 to 22 C atoms, R2 and R3 independently represent an alkyl group having 1 to 22 C atoms, hydroxyethyl or a polyglycol radical, X is an oxygen atom, NH, N—CH3 or a (OC2H4)z group with z=1 to 10, Y− is one of the anions CH3OSO3−, C2HSOSO3−, CH3COO−, Cl−, phosphate, lactate, citrate, and m and n independently represent an integer from 1 to 6; wherein the quaternary ammonium compound is present as a solid at room temperature of 20° C.;
(C) 15 to 50% by weight of at least one neutralized phosphoric acid ester of the general formula (II):
P(═O)(OR4)(OR5)(OR6)   (II) wherein R4, R5 and R6 independently represent
(i) an alkoxylated alkyl group having a hydrocarbon chain comprising 3 to 22 C atoms or an alkoxylated alkenyl group having a hydrocarbon chain comprising 3 to 22 C atoms, wherein the number of alkoxy groups per alkyl or alkylene group is between 1 and 10 and the alkyl groups or alkenyl groups in each case may be branched or straight-chain, saturated or unsaturated;(ii) an alkyl group having 3 to 22 C atoms or an alkenyl group having 3 to 22 C atoms that in each case may be branched or straight-chain, saturated or unsaturated, and/or(iii) hydrogen,with at least one of the radicals R4, R5 and R6 not being hydrogen.
