Extended Length and Higher Density Packages of Bulky Yarns and Methods of Making the Same
20170320698 · 2017-11-09 · ·

A method of winding bulked continuous filament yarn is disclosed, which enables superior yarn package formation, including higher density packages with excellent shape and yarn takeoff characteristics. The method uses unique helix angles and winding profiles in a non-adjacent and adjacent yarn pattern, achieved by a unique winding control strategy that constantly monitors spindle speed, desired wind ratio, traverse cam speed, and surface speed.

Package with high young's modulus yarn and method for winding the yarn package
10266365 · 2019-04-23 · ·

The invention concerns an improved yarn package and a method winding a package of high Young's modulus yarn. The package has a low normalized standard deviation in unwinding tension and hence is very suitable for converting into a range of yarn constructions and particularly medical products.
