Abstract: A method of manufacture of a rapid dyeing, deep dyeing, open structure polyamide yarn and to the yarn and to a fabric produced from the yarn includes the step of applying an aqueous finish to substantially all of the rapid dyeing, deep dyeing, open structure polyamide filaments. The aqueous finish consists essentially of a fluorosurfactant dissolved in water that is applied to bulked continuous filament yarn at an effective concentration level of preferably 150 to 600 parts per million by weight of flourine on yarn. The aqueous fluorosurfactant finish is applied at a point after texturizing and before windup.

Abstract: A synthetic polymer filament is characterized by a four-sided void that extends centrally and axially through the filament. Each apex of the void extends toward the approximate midpoint of one side of the exterior configuration of the filament. The four-sided void has a modification ratio in the range from about l.2 to about 2.0 and occupies from about five percent 5% to about thirty percent 30% of the cross sectional area of the filament. A spinneret plate for producing the thermoplastic synthetic polymer filament has a cluster of four orifices centered about a central point. Each orifice includes a generally isosceles triangle-shaped major portion from which extends a pair of legs, each leg of one orifice being spaced from the leg of an adjacent orifice to define a gap therebetween.
