Solution dyeing
o Its ot deig ad it a ot e a solutio
o Put color in melt or solution before extrusion
o Obviously, only applies to manufactured fibers
Solution dyeing : the good
o Usually use pigments, not dyes
o Excellent fastness (dye is locked in)
o No polluting dyeing process
o Must do it for olefin, and a good idea for kelvar
The fiber producser can also
o Dye tow (bundle of filaments)
Batch dyeing Machinaary
o Specific for form of textile: yarn, fabric
Other factors?
Pressurized? (most are now)
Tension on fabric ?
Allos ulkig
o Mostly made of stainless steel
o Poides elatie otio etee fie ad ath = stiig
o Can move

Both
o Heating is usually by steam coils in the bath
Dyeing fiber: loose stock
o Loose stock dyeing for heather yarns
o Typically large removable holders that fit into dye kettle: fill one,
dye one, unload one
o Fiber is still, pump moves dye liquor
Stock dyeing
Dyeing top
o Top: combined wool
o Colored, then combed together into yarn, also has heather
effects
Yarn dyeing machinerary (batch)
o Two major types:
o Skein (hank( dyeing
o Package dyeing
Yarn dyeing skiens
o Loose
o Skeins hang from poles, and dye goes upwards
o Yarn free to relax and bulk up
o Slow flow = less leveling
o Stick marks, sometimes
o Best for process for carpet yarn, hand knitting yarn
Yarn dyeing : packages
o Yarn is wound onto a former by a yarn spinner or by yourself if
you do not trust they will do it correctly
