Abstract
A helically crimped polypropylene filament is made by drawing a polypropylene filament having gamma orientation and an orientation angle of 10 degrees-36 degrees, said filament not having been pre-drawn at a draw ratio of greater than 1.86, at a draw ratio of at least 1.4 but not above a total draw ratio, including any pre-drawing, of 2.6, under such conditions that the total draw ratio is 60-100% of the maximum draw ratio, and thereafter releasing the drawing tension whereby said filament develops at least five helical crimps per inch. In a modification, the total draw ratio is at least 25% of the maximum draw ratio, and the drawn filament is then passed under tension at least 30 degrees around a hard surface having a radius of curvature less than 0.5 inch, and the tension then released, whereby said filament develops at least ten helical crimps per inch. The filaments may be dyed by treatment with a solution of dye subsequent to the drawing step and not appreciably over a minute after releasing the drawing tension. In an example, filaments are dyed by immersion in a 2% solution of Acid Red C.1.15675 in 50% aqueous ethanol for 2 mins. at 30 DEG C., and in solutions of Disperse Blue C.1.64500 in 25-99% aqueous ethanol, ethanol, N,N-dimethyl formamide and methylene chloride. Solutions of disperse, acid, or basic dyes may be used, but emulsions are ineffective. The dyed filament spontaneously crimps on releasing the tension. Specification 882,329 is referred to.
