Dyeing & Finishing
Bamboo fabrics dye extremely well and there is no limit to the imagination as to what you can create with these gorgeous fabrics. . . .
Light serging, enzyme de-sizing, moderate bleaching and semi-mercerizing should be applied to the bamboo fabric during its dying and finishing process. Avoid drastic conditions and use small mechanical tension.
Serging: moderate condition.
De-sizing: should be consolidate, de-sizing rate should be over 80%.
Scouring: pure bamboo normally needs no scouring, sometimes wash it with a little alkaline soap. The scouring process should be made in terms if fiber blend contains cotton. When pure bamboo fabrics are scoured, the alkali should not be over 10g/liter but be applied in accordance with the thickness of fabrics.
Bleaching: the processing should be made in terms of the specification and thickness of fabrics.
Mercerizing: the fabrics of bamboo fibers normally should not need mercerizing due to their sound lustre and bad anti-alkaline properties. However, some cases are found in order to increase their absorbance capacity to dyestuff.
Dyeing: Ideally use active dyestuffs during dying process – alkali should not be over 20g/liter, temperature should not be over 100° C. During drying process, low temperature and light tension are applied.
Yarn dyeing: the alkali should not be over 8g/l in yarn dying.
