Abstract
Polyolefin fibers, filaments and fabrics made therefrom which comprise a melt blend which comprises (A) a polyolefin; and (B) at least one polyetheresteramide which contains aromatic diol-derived sections, exhibit excellent durable dyeability. The fabrics are useful in woven garments, carpeting, furniture and automobile upholstery, woven industrial fabrics, non-woven absorbents used in disposable diapers, non-woven garments including disposable medical garments, filter media, synthetic paper and the like.
Claims20
A dyeable fiber or filament, comprising a melt blend which comprises
- (A) a polyolefin;
- and
- (B) at least one polyetheresteramide which contains aromatic diol-derived sections,
- wherein the aromatic diols are selected from the group consisting of
- 5
- wherein
- R1 and R2 independently are ethylene oxide or propylene oxide,
- Y is a covalent bond, an alkylene group of 1 to 6 carbon atoms, an alkylidene group, a cycloalkylidine group, an arylalkylidene group, O, SO, SO2, CO, S, CF2, C(CF3)2, or NH,
- X1 and X2 are independently hydrogen, an straight or branched alkyl of 1 to 6 carbon atoms, aralkyl of 6 to 10 carbon atoms, aryl, halogen, sulfonic acid or sulfonic acid salt,
- j is 0 to 4 and
- m and n are independently 1 to 32.
A method for imparting permanent dyeability to polyolefin fibers or filaments or woven or nonwoven fabrics made therefrom, comprising melt extruding a mixture comprising a thermoplastic polyolefin and at least one polyetheresteramide which contains aromatic diol-derived sections into a plurality of fibers and cooling the fibers,
- wherein the aromatic diols are selected from the group consisting of
- 6
- wherein
- R1 and R2 independently are ethylene oxide or propylene oxide,
- Y is a covalent bond, an alkylene group of 1 to 6 carbon atoms, an alkylidene group, a cycloalkylidine group, an arylalkylidene group, O, SO, SO2, CO, S, CF2, C(CF3)2, or NH,
- X1 and X2 are independently hydrogen, an straight or branched alkyl of 1 to 6 carbon atoms, aralkyl of 6 to 10 carbon atoms, aryl, halogen, sulfonic acid or sulfonic acid salt,
- j is 0 to 4 and
- m and n are independently 1 to 32.
