Dying
and Finishing of Bamboo Textile |
|
| Light
sergeing, enzyme desizing, moderate bleaching and semi-mercerizing
should be applied to the bamboo fabric during its dying
and finishing
process, which also avoid drastic condition and use small mechanical
tension. |
|
1. Sergeing
moderate
condition
2. Desizing
should
be consolidate, desizing rate should be over 80%.
3. Scouring
pure bamboo normally need no scouring, sometimes wash it with a
little alkaline soap. The scouring process should be made in terms
of contents blended with cotton. When pure bamboo fabrics are under
scouring, the alkali should not be over 10g/liter but be applied
in accordance with the thickness of fabrics.
4. Bleaching
the
processing should be made in terms of the specification and thickness
of fabrics.
5. Mercerizing
the
fabrics are normally free of mercerizing due to their sound luster
and bad anti-alkaline. However, some cases are found in order to
increase their absorbance capacity to dyestuff.
6. Dying
It had better to use active dyestuff during dying process, and the
alkali should not be over 20g/liter, the temperature should not
over 100c. During drying process, low temperature and light tension
are applied.
7. the alkali should not over 8g/l in yarn-dying,.
The above mentioned data are just for your
reference, you should adjust them accordingly. |
