ABSTRACT:
A method for manufacturing a textured yarn from an artificial multi-filament yarn consisting of a plurality of continuous mono-filaments, by folding up the mono-filaments in multiple layers and entwining them by genuine twists to form a textured yarn which has the appearance, touch and texture resembling a spun yarn. The process is made up of the steps of spreading into individual filaments a continuous multi-filament yarn of artificial fiber, passing part or all of the spread-out filaments onto the periphery of a rapidly-rotating spindle of a conical or cylindrical shape, assembling the filaments around the spindle in the form of a sleeve constituted by thin filament layers, and continuously withdrawing the sleeve from the spindle at a speed which is lower than the feed speed of the multi-filament yarn, the sleeve being withdrawn either in a straight forward direction along the spindle axis or in a backward direction through an axially-extending passage in the spindle after being everted at the nose thereof. Alternatively, an additional yarn may be introduced as a core thread into the sleeve while it is being withdrawn from the spindle, which also results in a core yarn which has the appearance, handling and texture resembling a spun yarn.
