Printing and dyeing grade sodium alginate use
1.Printing paste
Sodium alginate used in warp sizing, trimming paste, printing paste
has a long history, but mainly in the printing paste, sodium
alginate is used as active dyestuff, with unique properties.
Reactive chemical fiber and a reaction, the dye fixed on the fiber,
the dyeing process used in printing paste should not interfere with
or participate in chemical reaction bonding. Involved in the
response if the color, will be fixed in the fiber, which resulted
in hand dyed fibers made of hard, brittle, the color is not good.
When using sodium alginate as the printing paste, dyeing process
does not affect the reactive dye and fiber, and print out a clear
pattern, bright, color yield high, feel is good, is not only
suitable for chandar ink, also suitable for wool, silk, synthetic
fiber printing. Medium viscosity and low viscosity sodium alginates
are all fit on the screen printing to barrel-type printing paste
requirements. The printing paste with low viscosity sodium alginate
were actually more stable. This makes the printing paste prepared
with higher content of possible, this kind of printing paste can
lead to dense film during drying process, the dyeing rate
increase.
2.Man-made fiber
Sodium alginate and short asbestos fiber mixed with calcium acetate
solution, solidification processing, can prevent the asbestos fiber
dust, affect the health of the human body.
