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.

Disclosed is a method for fabricating coils including the steps of providing a liquid droplet having a diameter on length-scales ranging from hundreds of micrometers to nanometers and bringing a fiber into contact with the liquid droplet, wherein the radius of the liquid droplet is sufficiently high in comparison to the bending elastocapillary length which is defined as where E is the Young's modulus of the elastic fiber, r is the radius of the fiber and is the interfacial tension between the droplet and surrounding medium, so that capillary forces induce the spontaneous winding of the fiber around the droplet, to fabricate a coil with a diameter in the range from hundreds of micrometers to nanometers. Also disclosed is a system for making microcoils and to the product thereof.

The invention relates to a process and an apparatus for the production of coarse count and tridimensional crimped multifilament BCF (Bulk Continuous Filament) yarns, starting from polyamide 6.6, which envisages cooling in water and subsequent non-mechanical treatment with a mixture of air and steam, such that the yarns obtained have controlled chemical-physical and mechanical properties; the invention also relates to the yarns obtained by the aforesaid process and/or the aforesaid apparatus, both in a wound form in a cut form.

The coarse count and tridimensional crimped multifilament BCF yarns having controlled chemical-physical and mechanical properties according to the present invention are suitable for non-textile applications and are preferably and advantageously employed in the manufacture of carpets for large surfaces.
