Abstract
A hot-melt-adhesive composite fiber having a broad temperature range of hot-melt adhesion, exhibiting a low heat-shrinkage over the whole temperature range thereof, having a high tenacity and suitable to production of a non-woven fabric having superior restoring properties, bulkiness, draping properties and feeling is provided, which composite fiber comprising a fiber-forming component and an adhesive component, the fiber-forming component comprising 0.5 to 30% by weight of a copolymer of a carboxyl group containing modified polyolefin with a polyamide, and the adhesive component comprising a carboxyl group-containing modified polyolefin, an unmodified polyolefin or a mixture thereof.
Claims13
A hot-melt-adhesive composite fiber comprising a fiber-forming component and an adhesive component, said fiber-forming component comprising 0.5 to 30% by weight of a copolymer of a carboxyl group-containing modified polyolefin with a polyamide and 70 to 99.5% by weight of a polyester, the proportion of said carboxyl group-containing modified polyolefin in said copolymer is in the range of 0.5 to 60% by weight, and said adhesive component comprising a carboxyl group-containing modified polyolefin, an unmodified polyolefin or a mixture thereof.
