Dyeing procedure of reactive dyes
1, roll bake roll the steaming two baths law handicraft
(1) technological process:
Roll dye dry stoving in advance roll the alkali vapor steaming nothing but clear soaping water scrubbing stoving
(2) condition:
Soak rolling a dye liquor: Liquid warms up 20-30 ~C , rolls spare time rates =70%
Bake in advance: Infrared ray , the horizontal stroke heat conduction groundless , step by step, litre, warm up , dry spare time rates =30%
Dry: Hot wind or the cylinder dries dryness , dries one by one step
Soak rolling a dye liquor:
(A) the rolling mill, runs over spare time leading <75%
(B) steams box liquid seal , rolls spare time rates =100-110 %
The vapor steams the temperature: 102-104 ~C
The vapor steams time: 40-90 seconds
Redress nothing but: Cloth cover redress nothing but till the neuter
Soaping: Above 95 ~C, the sufficient soap cooks
Water scrubbing: Wash soap liquid clean
Dry: Dry dryness homogeneously
(3) dye liquors assemblies:
Dyestuff: X g/L
Defend against swim to move an agent: 1-2 g/L
Urea: 0-30 g/L
Seep through an agent: 0-2 g/L
(4) blends the alkali liquor assembly:
NaOH 38' Be' 10-15 ml/L
Na2CO3 20-40 g/L
NaClOrNa2SO4 150-200g/L
Defend against dye salt S 0-10 g/L
2. Roll-bake-bath law handicraft
(1) technological process:
Roll dye dry stoving in advance bake dry nothing but clear soaping water scrubbing stoving
(2) condition:
Soak rolling a dye liquor: Liquid warms up20-30 ~C , rolls spare
time rates =70%
bakes in advance: Infrared ray , the horizontal stroke heat conduction are groundless , litre of temperature dries
step by step: Hot wind or the cylinder dries dryness , stoving bakes one by one
step to dry the temperature: 140-160 ~C
(3) dye liquors assemblies:
Dyestuff: X g/L
Urea: 30-120 g/L
Baking soda: 10-30 g/L (NaHCO3)
Defend against dye salt S: 0-10 g/L
Defend against swim to move an agent: 1-2 g/L
Seep through an agent: 0-2 g/L
Give exegesis or explanation: Soak the fabric rolling a dye liquor drying the day afer tomorrow must be in progress immediately bake dry the sum soap cook handle.
3.1 high temperature move acquiring handicraft
3.2 constant temperature handicraft
3.3 changing temperature handicraft
