Abstract: A yarn having a number of filaments is passed through between intercrossing work surfaces of two intercrossing endless belts which run in pressing engagement with each other. By suitably selecting the intercrossing angle of the belts, tension acting on the yarn and heater temperature, a crimped filament yarn is prepared having S-twist and Z-twist portions distributed in alternation along the length of the filament yarn. The filaments are tightly engaged with each other in the S-twist (or Z-twist) portions while being separated from one another in the Z-twist (or S-twist) portions. A fabic using such crimped yarn is dyed to cause the tightly bound portions to appear in a dark shade of color and the loosely bound portions in a light shade, thereby producing a salt-and-pepper pattern.

Abstract: Two or more single strands are formed and false twisted to provide sections of S-twist and Z-twist which are longitudinally spaced apart and separated by nodes which have no twist. The strands while moving longitudinally are held against rotation at points between which the adjacent strands twist in a same direction. The twist between each pair of points becomes redistributed, and the strands are released to enable them to twist together to form a self twist plural strand yarn.The strands are held against rotation during twist redistribution by apparatus which includes a device for interconnecting the strands at the points, and a rotation preventer which moves with and lies between the strands adjacent to the interconnected points.

Additional torque in the plying direction is applied beyond the equilibrium point to add twist to the plied strands. Jet devices using air or steam can be used to apply the additional torque.

Abstract: A bulk yarn formed from a plurality of multi-filament yarns having alternating compact and open segments. The compact segments include first and second plaited portions which are twisted in opposite directions. The open segments of the yarn are defined by loosely bundled multi-filament yarn.

Abstract: A stable plied yarn is produced by false-twisting two or more singles yarn strands with false-twist jets and passing the strands around a yarn wheel whereon the nodes are joined. The strands leave the wheel and ply together. The plied yarn is collected and can be tufted into carpet. The pressure of the fluid (air) supplied to the false-twist jets is varied to product varying amounts of twist in the singles strands which results in a range of twist amounts in the yarn plied therefrom, thereby avoiding streak effects in products made from the yarn.
