Pre-dyeing includes various dyeing processes exactly where the yarn is dyed previous to tufting. The most common of those solutions is known as Option dyeing. Included in this dyeing strategy are Alternative dyeing, Area dyeing, inventory dyeing, and skein dyeing.
Answer dyeing is received by pre-heating into the polymer melt position, where by it obtains a liquid state. At this time,
dye pigments are dispersed into your polymer melt to get the specified color. This now colored polymer soften is
extruded via a gadget often known as a spinneret, which is similar into a showerhead. As being the polymer melt is
extruded, the fiber cross-segment is set by The form of the holes inside the spinneret plus the extruded fiber is
air-cooled and solidified. For the reason that Answer dyeing dyes the fiber through, rather then impregnating dye in to the
fiber, this process of dyeing makes the simplest stain cleanability of all fibers.
Space dyeing, referred to also as yarn dyeing, is actually a approach made use of primarily in numerous varieties of business carpet
loop constructions constructed from or such as the usage of continual filament nylon. In this process of dyeing, two or
much more distinct colours are fundamentally printed together the duration of the fiber to create a multi-color have an effect on In a nutshell
lengths with the fiber that commonly show up as horizontal or diagonal stripes. This is often done by printing other colors on
the base color by knitting vodoinstalaterske usluge cene the yarn into narrow tubes. The tubes are steamed and dried. The yarn is then de-knitted
and wound onto cones for tufting or warping. Space dyed nylon is commonly used in carpet made mainly from
Answer dyed yarn to supply accent colour.
Skein dyeing also known as An additional type of yarn dyeing is similar to stock dyeing. Skein dyeing entails a
procedure exactly where yarn is wound into big skeins which are hung in dye vats and after that dyed to provide smaller sized dye tons.
Following dyeing the yarn is then wound onto cones. Skein dyeing is commonly utilized to dye personalized shades.
Stock dyeing is regarded as being the oldest approach to dyeing carpet yarns. In this process, large portions of staple
yarns are positioned in a big vat ("kettle"), and therefore are dyed under pressure using non-h2o soluble disperse dyes. After
dyed, the kettle is drained along with the yarns are then centrifuged to remove excess h2o. Inventory dyed yarns need to go
with the spinning and warmth-placing approach. The vast majority of polyester fiber is dyed by this method.
