KIER BOILER
It has capacity of 15000 to 17000 Fabric from grey mercerization undergoes cold wash. Fabric from desizing undergoes hot and cold wash Then the material from both undergoes caustic boil in kier boiler Inside kier hot wash and cold wash is done Then treated with Hcl for scouring twice. Then cold wash is done after that soda is added Then the fabric is treated with chlorine for two times.
Then cold wash along with tinting is done.Then treated in hydrogen peroxide boiling for 4 hours in open boil.

BEAM DYEING
In this process the solution only rotates. Beam width is 180 cm Holes to holes 150 cm
BEAM DYEING PROCESS
making of beam batching as per the width of fabric and overlap should be 3.5 cm over the beam end piece should be placed to reduce the end variation in fabric fabric should winded with proper tension in beam dying m/c water capacity is 800 ml reverse I s 3 minutes glycerein should be placed in rubber washer above the end piece a fabric should be place to reduse the shade variation after placing fabric water is added. After accetic acid and saromata and then steam make it 60deg temperature then check pH when pH is 4 to 5 sarcomata carrier TCI is pump into it maintain to 60 deg and added leveling agent (cidogen DETC is pump into it) when pH is not B/W 4 to 5 acetic acid also added then dye is added then temp is added to 90 deg by 10 minute I.e for every 1 minute 3deg is increased afer attaining 90deg. Every 1 min 2deg is added attain 130 deg within 20 minutes At 130 is maintain to 10 to 15 minutes Simple is checked Temperature is redused to 90 deg m/c is ruin off when shade is not match again repeated after comes to 90 deg due to high temperature and pressure after complete rein off
Speed is 20 to 120 m/min and width of fabric from 60 to 160 cm
Temperature varies, depends on fabric
DRYING / PADDING
Dyes : silicate = 4:1
To Remove excess colour
→ hydros caustic for 6 end
PRINTING:
Flat screen Printing machine -1 No.
Labours - 6
FLAT SCREEN PRINTING
-Reactive
-Discharge
-Pigment
Note:
PVA is applied to the blanket to hold the fabric tightly whose intensity varies according to fabric thickness & repeat of the print.
REACTIVE:
Printing the fabric using reactive dyes.
After printing is done, fabric is passed through silicate padding for curing for a minimum of 16 hrs to a max of 24 hrs.
Drying Calendaring Finishing
The fabric to be passed through silicate padding is passed with the print downside.
Pressure of the padding mangle = 3.5 kg
DISCHARGE:
Fabric is passed through the ager for curing after printing.
The color of the fabric/print looks grey i.e. in the dull dust color after printing.
The required color of the print is attained only after ageing.
PIGMENT:
Pigment is used as the printing paste.
The print is dried in steam after printing, which sets the print & gives the original color.
RECIPE FOR PREPERING PRINTING PASTE:
1. Alsinate -45 kgs2. Cisalsin -8 kgs3. Kerosene Emulsion – 7kgs4. Water - 40 kgs
First mix cisalsin& kerosene Emulsion with water, then add Alsinate.Incase of Reactive paste, after mixing the paste with dye, purify the mixture.
ALSINATE:
1. Alsinate powder -3.5 kgs2. Printing gum -1 kg3. V.M Powder -0.5 kgs4. Hot water(40-45◦C) -95 Kgs
Add in mixer & prepare the paste.
CISALSIN:
1. Cisalsin powder -10 Kgs2. Emulsifier -1 Kg3. M.T.O -20 Kgs4. Hot Water(40-45◦C) -70 Kgs
First add cisalsin powder & mix in hot water & then add M.T.O & Emulsifier.
KEROSENE EMULSION:
1. M.T.O -90 Kgs2. Emulsifier -1 kg3. Water -10 Kgs
First mix M.T.O & Emulsifier and then mix it with water slowly
PIGMENT PASTE:
1. Binder -10 Kgs2. Lubrindal M.C.L -1.5 Kgs3. Lutex H.E.F -2 Kgs4. Urea -1.5 Kgs5. Water -70 Kgs
First mix binder and urea with water and then add lubrindal M.C.L & then mix lutex H.E.F.
