Problems solved by technology

However, these inventions all relate to a kind of parallel cheese (parallel cheese) as its basic shape, and when the elastic thread is unrolled from the fixed cone along the end face direction of the cone, the unwinding resistance is greater than that of cone cheese (cone cheese). ) resistance, especially, in the case of pure polyurethane elastic thread etc., large unwinding resistance can cause problems such as yarn breakage and irregular supply tension

[0062] A 46.62 tex (tex) polyurethane elastic thread (manufactured by FujiSpinning Co., Ltd., trademark: FUJIBO SPANDEX) weighing 3.0 kg was prepared, which was wound in the form of a parallel bobbin On cylindrical spools and without lubricant. Next, as initial setting values, input the taper angle a=3°30′, the smaller diameter of the bobbin=0.047m, the larger diameter of the bobbin C=0.075m, and the bobbin width F = 0.2286m, linear distance between the larger diameter end face of the bobbin and the position where winding starts at the tapered larger diameter side of the bobbin E = 0.015m, winding width D = 0.195m, spindle center and lateral support The linear distance between the guides H=0.2m, the initial value of the spindle revolution SP 0 = 24.77 revolutions / second and the number of turns during the transfer of the transverse guide from the larger diameter side of the bobbin to its smaller diameter side = 3.25. Obtain the calculated value of bobbin diameter A = 0.0493m ...

Abstract

The present invention relates to a cone of an elastic yarn, which has a superior form and is excellent in unwinding the elastic yarn from the cone. In winding the elastic yarn on a tapered bobbin, a position of traverse support guide is moved so that a ratio (V1 / V2) of winding velocity (V1) at a smaller end face of a cone of said tapered bobbin to a winding velocity (V2) at a larger end face of a cone of said tapered bobbin and a ratio (L2 / L1) of a linear distance (L2) between the traverse support guide and the larger end face of a cone of said tapered bobbin to a linear distance (L1) between the traverse support guide and the smaller end face of a cone of the tapered bobbin becomes nearly equal. An average value of unwinding resistances of the elastic yarn from the cone of elastic yarn obtained is in a range of 3.2g to 3.4g.

Description

technical field [0001] The invention relates to a method for winding an elastic thread on a conical barrel in a suitable conical-like form. The obtained elastic cone has excellent unwinding characteristics, and can provide a cone with a cone suitable for supplying yarn used in the production field of industrial materials such as paper diapers and in the production field for warp knitting and warping. Wound yarn body of shaped elastic thread. Background technique [0002] A wound yarn body having a tapered shape obtained by winding the yarn on a tapered drum while the yarn moves laterally is widely used in the winding of ordinary spun yarns and synthetic fiber yarns such as polyester and nylon , this is due to the excellent unwinding characteristics of the yarn when it is taken out from the fixed corn along the direction of the end face of the cone. However, since the winding speed of the bobbin is different between the larger diameter side and the smaller diameter side whe...
