Abstract
1,266,182. Spinneret for T-shaped filaments. FIBER INDUSTRIES Inc. 20 June, 1969 [20 June, 1968], No. 31206/69. Heading B5B. A spinneret for melt-spinning filaments of T-shaped cross-section from filament-forming polymers has a plurality of T-shaped orifices (Fig. 5), the stem 16 of the T extending perpendicularly from the mid-point of the cross-bar 15, the hole aspect ratio (HAR) (defined below) of each orifice being from 2À6 to 86À0, and the orifices being arranged in a circle with the stem of the T of at least half of the orifices extending from the cross-bar in a direction away from the centre of the circle (Fig. 3, not shown). With reference to Fig. 5, the HAR=(x+y)/Z; preferred lengths and widths are L c and L s = 0À007-0À060 inch, W c and W s =0À002-0À020 inch. The orifice produces a trilobal filament (filament aspect ratio FAR=1À8-2À6) (Fig. 6); with reference to Fig. 6, the FAR is defined as a/b. T-section filaments may be spun without kneeing (Fig. 2, not shown), and uniform, continuous filaments are obtained. Exemplified polymer is polyethylene terephthalate, and the filaments are cooled in air.
