초록 ▼

Multi-component mixed filament, wherein at least two spinning materials having poor affinity are mixed and dispersed in unitary filament in a nebular configuration containing at least 50 stars at least in one portion of the cross-section of the filament and the nebular configuration continues substantially in the longitudinal direction of the filament is manufactured by subjecting said spinning materials to at least eight times of "joining and dividing step in different phase" repeatedly to layer-multiply said spinning materials so as to form a nebular configuration in the cross-section of the resulting filament and then extruding the resulting mixture from orifice in a spinneret. In this manufacture, the preferable combinations of said two spinning materials having poor affinity are polyamide-polyester, polyamide-polyalkylne oxide, polyester-polyalkylene oxide and polyamide-polyolefin.

대표청구항 ▼

1. A multi-component filament formed by mixing and dispersing two different spinning materials having poor affinity and selected from the group consisting of nylon-6, nylon-66, polyethylene terephthalate, polyethylene oxybenzoate, polyolefin and polyalkylene oxide in a unitary filament having a part of its cross-section constituted with a nebular configuration and a part with no nebular configuration, a surface of the filament being occupied with at least two components forming said nebular configuration which contains at least 100 cross-sectional structures having a variety of shapes and sizes, said nebular configuration continuing substantially along the longitudinal direction of the filament, and said cross-sectional structures being dispersed irregularly in the other spinning material, which is obtained by subjecting repeatedly said two spinning materials to a joining step in a narrow channel and a dividing step in a reservoir or to a joining step in a reservoir and a dividing step in a narrow channel in different phase at least eight times to be layer-multiplied. 2. The filament as claimed in claim 1, wherein the part having the nebular configuration and the other part are conjugated in a side-by-side relation. 3. The filament as claimed in claim 1, wherein the part having the nebular configuration and the other part are conjugated in a sheath-core relation. 4. The filament as claimed in claim 1, wherein the part having the nebular configuration and the other part are conjugated eccentrically. 5. The filament as claimed in claim 1, wherein the part having the nebular configuration and the other part are conjugated concentrically. 6. The filament as claimed in claim 1, wherein said number of stars is more than 200. 7. The filament as claimed in claim 1, wherein said polyamide consists essentially of nylon-6 or nylon-66. 8. The filament as claimed in claim 1, wherein said polyalkylene oxide consists essentially of polyethylene oxide.
