Dty, draw textured yarn, is the most used texturing process in synthetic fabrics. dty process is similar to perming hair. after heating, the raw material is drawn and twisted/untwisted simultaneously resulting a bulked stretchy yarn. the process is called false twist. dty maintains characters of synthetic filaments.
Drawing, in yarn manufacture, process of attenuating the loose assemblage of fibres called sliver (q.v.) by passing it through a series of rollers, thus straightening the individual fibres and making them more parallel. each pair of rollers spins faster than the previous one. drawing reduces a s
So the term partially oriented yarn refers to multi-filament that is only partially stretched. poy is generally lower tenacity and less uniform than fully oriented yarn (foy). poy is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics. what is fully oriented yarn (foy)?
For draw textured polyamide yarn dye packages, however, twin- heater machines can be advantageous, offering more flexibility to: • pre-stabilise the yarn, reducing shrinkage in the package dyeing operation, leading to more uniform dye uptake within the package. •
