Abstract
A method of manufacturing multi-ply separable textured yarn, the method comprising, passing a multi-ply separable interlaced filament yarn through a texturizing unit to form a multi-ply separable draw textured yarn, wherein the multi-ply separable interlaced filament yarn is separable in to at least two separable interlaced filament yarn, wherein the interlacing of the filaments within each separable interlaced filament yarn is retained during further processing of the yarn to fabric and in the fabric.
Claims5
A method of manufacturing a separable interlaced filament yarn, the method comprising:
- a) passing a polymer melt through a spinning unit to form a plurality of molten streams;
- b) cooling the molten streams in a quenching zone to form plurality of polymer filaments;
- wherein said polymer filaments are not side-by-side or seath-core bi-component filament;
- c) grouping the filaments to form a yarn;
- and
- d) passing the yarn through at least one interlacing means for strong interlacing the filaments within the yarn by setting the parameters for strong interlacing to provide a separable interlaced filament yarn;
- wherein the interlacing of the filaments within the yarn is significantly retained during further processing of the yarn to fabric and in the fabric so that yarn Ply of said Separable Interlaced filament yarn is Separable from other yarn plies in the fabric;
- Wherein parameters for strong interlacing are number of interlacing devices, number of filaments in the yarn, type of the filament, denier of the yarn, speed of the yarn passing through the interlacing devices, number of jets in the interlacing devices, number of nozzles in said jet, diameter of nozzles, type of fluid passed through the nozzles of the jets for causing interlacing of filaments and pressure of the fluid.

A method for manufacturing a multi-ply separable draw textured yarn (DTY), the method comprising:
- passing at least one multi-ply separable interlaced filament yarns through a texturizing unit/spindle, wherein the multi-ply separable interlaced filament yarn is separable into at least two separable interlaced filament yarn;
- wherein the interlacing of the filaments within each separable interlaced filament yarn is retained during further processing of the yarn to fabric and in the fabric so that yarn Ply of said Separable interlaced filament yarn is Separable from other yarn plies in the fabric or
- passing two or more Separable Interlaced filament yarns through a texturizing unit/spindle, wherein the interlacing of the filaments within said yarn is retained during further processing of the yarn to fabric, and in the fabric so that Ply of said Separable Interlaced filament yarn is Separable from other yarn plies in the fabric;
- or
- passing a combination of one or more Multi-Ply Separable Interlaced filament yarn and single Ply Separable Interlaced filament yarns through a texturizing unit/spindle, wherein the Multi-Ply Separable Interlaced filament yarn is Separable in to at least two Separable Interlaced filament yarns, wherein the interlacing of the filaments within said yarn is retained during further processing of the yarn to fabric, and in the fabric so that Ply of said Separable Interlaced filament yarn is Separable from other yarn plies in the fabric;
- to form Multi-Ply (Multiple Yarns) Separable draw textured yarn, wherein the Multi-Ply Separable Draw Texturised yarn is Separable in to at least two Separable Draw Texturised yarns and wherein the interlacing of the filaments within said Separable Draw Texturised yarns 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 other yarn plies in the fabric.
