Woven twill textile fabric

A method of manufacturing a draw textured yarn, the method comprising the steps of:

• passing a polymer melt through a spinning unit to form a plurality of molten streams;
• cooling the plurality of molten streams in a quenching zone to form a plurality of polymer filaments;
• grouping the polymer filaments to form a yarn;
• passing the yarn through at least one interlacing unit for interlacing the filaments within the yarn by adjusting the interlacing parameters to provide a separable interlaced filament yarn;
• and
• retaining the interlacing of the filaments within the yarn during further processing of the yarn to fabric.

A method of manufacturing a multi-ply separable draw textured yarn, the method comprising any of:

• (a) passing two or more interlaced yarns through a texturizing spindle;
• (b) passing at least one multi-ply separable interlaced filament yarn through a texturizing spindle, wherein the at least one multi-ply separable interlaced yarn is separable into at least two interlaced yarns;
• and
• (c) passing a combination of at least one multi-ply separable yarn and at least one interlaced yarn through a texturizing spindle, wherein the multi-ply separable yarn is separable into at least two interlaced yarns to provide the multi-ply separable draw textured yarn,
• wherein the multi-ply separable draw textured yarn is separable into at least two separable draw textured yarn, and wherein interlacing of filaments within the separable draw textured yarn is retained during further processing of the yarn to fabric and in the fabric so that ply of said separable draw textured yarn is separable from one other yarn plies in the fabric.
