Air Interlacing and Tangling Machines
topic
Air interlacing machines pass multifilament yarn through a low-pressure air nozzle at 1 to 3 bar that creates periodic entanglement points of 10 to 30 per metre spacing where filaments are knotted together, replacing mechanical yarn sizing for warp preparation by providing cohesion that prevents filament separation during weaving without adhesive application, with interlace level controlled by air pressure and yarn tension at the nozzle.
Role
Provides filament yarn cohesion for weaving warp preparation as an alternative to sizing by creating periodic inter-filament knot points that prevent filament fraying during heddle and reed contact, with air interlacing being a clean, chemical-free alternative to size application that eliminates the desizing step required after weaving, reducing wet processing waste and effluent while providing adequate warp integrity for the majority of woven filament fabric constructions.
