Overview:
The
brand Liduo compound printing paste: It regards the unique
natural plant and high performance carboxymethyl starch (CMS)
which are produced in Gansu sub-plateau and semiarid region as
the main material. We employ the innovation technology and patent
equipment to produce the new generation of green printing
auxiliary. It is also the ideal product to replace the sodium
alginate in the textile printing industry. This printing paste
has not only the advantages of high yield of forming thickening
agent, but also good rheological properties, thixotropy, holding
water capacity, screening, dilution resistance, alkali and salt
resistance. It also overcomes the disadvantages of the
traditional sodium alginate printing paste in the printing
process such as the low color yield and brilliance, bad screening
and short retention time of the original paste. The
performance/price ratio of this paste is much higher than the
sodium alginate and it is the most advanced printing paste
products at present.This innovation technology and products have
also already passed through the Gansu Province Technological
Achievements Acceptance and the Gansu Province New Product
Identification in ***1. The achievements have reached the leading
domestic level, which fills up the domestic fine chemical gap in
the area of printing paste new materials.

good
Applicable
Scope:
Applicable
dye: reactive dye.
Applicable
process: conventional printing technology.
Applicable
equipment: rotary and flat screen printing machine.
Applicable
fabrics: TQHY*1 compound printing paste is applicable to middle
high cellulose fiber fabrics. TQHY*2 compound printing paste is
applicable to middle low cellulose fiber fabrics.
Directions:
1. It
has the same usage method with the sodium alginate pastes, there
is no need to be changed.
2. Put
the sodium carbonate, sodium bicarbonate, reserve salt-S, urea
directly into the cold water which was soften by sodium
hexametaphosphate. When it is blended and fully dissolved,
Sprinkle the printing paste into the water (***0 r/min, *0min).
The original paste is made while the paste is dissolved
completely.
3. Place
the original paste should for ***2 hours, and then strain over
the dye liquor, mix uniformly to use in the screening
machine.
4. Add
****0% sodium alginate when apply TQHY*2 compound printing paste
to the middle high cellulose fiber fabrics.
Cautions:
1. According
to the different techniques and fabrics, adjust the usage
proportion of the printing paste to use in the screening
machine.
2. Aiming
at the different techniques and fabrics, adjust the usage of
auxiliary agent.
3. Take
advice to use the plastic or stainless steel bucket to beat,
because the viscosity of the paste decreases when adding metal
ion Ca2+, Mg2+, Fe2+, etc.
4. Use
the water to dissolve the dye liquor (the temperature must be
*0oC below), and strain over the original paste. Because the
viscosity of the printing paste decreases when the original paste
and color paste are heated by the hot water.
5. The
color paste should be used on that day and not be suitable for
storage over long period.
