6. Process
The fiber dyeing carriers can also be used in which the hanks are piled ,
just like in kier
dyeing and bleaching can be done. This method is useful for hard
twisted and coarser
yarns, which are difficult to penetrate under normal atmospheric
conditions of cabinet
dyeing machines. The hanks are loaded into suitable dyeing carriers,
which are having
either straight sticks or circular sticks for loading of hanks. The hanks
of different sizes
can be accommodated as in the case of cabinet dyeing machines. The
carriers are then
put into the dyeing machine kier and rest of the process is carried out
as in case of
cheese dyeing . The flow rate and reversal of dye liquor direction are
optimized as per
the quality of the yarn.

7. Conclusion
The need of textile industries of
technologically advanced and efficient
machineries is identified for dyeing
process. Manual process of dyeing of yarn
is laborious and involves errors in dyeing
which affects the major quality parameter
of textile product. Dyeing
solutions/technology available in the
market is a costly affair and may not be
affordable to SME’s and cottage industries.
A simple machine is conceptualized for
eliminating the problems associated with
manual dyeing process considering the
need of the beneficiary industry. Next
phase of this research is to model a
conceptual design in order to carry out a
motion synthesis in order to assess its
functionality.
