Title
(EN) Effectively printable polymide yarn, process for making the same, and fabric produced therefrom
Abstract
(EN)

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.
