KNOW THE CHEMICALS FOR CAUSTIC WASH: Silicone Softener
Caustic soda – Caustic soda – Works as a detergent but does not change the color of the dye. More effective than Soda ash. Create a faded, old look effect for garment wash.
Soda ash – Soda ash – It is also used to remove colors often used for pigment dye, creating fading effects, old look on the seams, bags, pants …
Detergent – Washes impurities on the fabric surface and a part of the color is also removed.
Acetic Acid – Acetic acid – Alkali neutralizes effect and creates mild acid pH during washing process.
Softener – Softener – The effect of creating a smooth, soft surface.
Silicon – Softening effect, elastic and durable as well as washing.
KNOW THE CHEMICALS FOR THE ENZYME WASHNeutral enzyme polymerization process
Desizing agent
Detergent
Dispersant – Anti back staining agent
Acetic acid – Acetic acid
Cationic softener – Cationic softener
Chlorine bleach – Chlorine bleach
Soda – Soda ash
Reducing agent – Sodium hypo sulphite
Silicone soft paste.
FOLLOW THE FIRST STEPS OF THE CAUSTIC WASH PROCESS:
Load the washing machine weight (Lot size): Example ……………. 80 kg.
Add water (Add water) Capacity L: R = 1: 8 (= 80x 8) ………… .. 640 Lit
Running the Machine (Machine Running.)
Add caustic soda (Add Caustic soda (NAOH)) 1.60 g / lit …………. 1024 g.
Adding Detergent …………. 8 g / lit ………… 512 g.
Temperature ……… .. 50 ° c to 60 ° c.
Time depends on the color required (Depend upon the shade) 20 to 60 minutes.
Drop the liquor.
Add water (Water ratio) L: R = 1: 10 (= 80x 10) ………… .. 800 Liters
Add Acetic Acid (Add Acetic Acid) 0.3 g / l …………………………… 240g.
Neutral wash cold water …………………… .. 3 minutes.
Drain water
HOW MUCH RPM MACHINE STANDARD ?::
From 28-35 RPM (Revolutions per minute.)
KNOW THE CHEMICALS USED FOR THE SOFTEN WASH PROCESS
Cationic softener – Cationic softener
Silicone soft paste – Silicon
Enzyme
KNOW THE CHEMICALS USED TO CREATE GOOD HAND FEEL FOR WASH CLOTHING:
Cationic softener – Cationic softener
Silicone soft paste – Silicon
Enzyme
CHEMICAL TO USE THE POSSIBILITY OF THE COLOR TO RETURN TO THE FACE OR BAGS IN THE WASH PROCESS:
Dispersant or Anti-back staining agent.
WHAT IS THE UNION TO REMOVE OR LOSE ON THE FABRIC IN THE WASH CLOTHING PROCESS? :
Desizing process or Desizing process
WHAT IS THE ROLE OF ACETIC ACID IN THE ENZYME BATH?
Acetic acid is used in the wash enzyme to neutralize clothing from an alkaline environment and to create a wash tank.
Creates mild acid pH for acid wash enzyme process.
THE DIFFERENCE BETWEEN STEAM DRYER AND GAS DRYER (GAS DRYER).
Steam dryer Gas dryer
· Low productivity. · High productivity.
· Often used for drying products that are thin, light, bright, or white. · Often used to dry thick, heavy, slow-drying products.
· There is no risk of product falling. · The product may fall after drying.
Describe the desizing process (DESIZING PROCESS) for DENIM pants:
Wash wash (Lot weight) eg 80 denim pants ………… 60 kg.
Add water Capacity L: R = 1: 9 ………… .. 540 Lit
Running the Machine (Machine Running.)
Heating (Temperature) …………………… .. 60 ° c.
Add Desizing agent 6 g / lit ………… 324 g.
Add detergent (Add Detergent) 0.8 g / lit ……………… .. 432 g.
Running the machine (Time) ………………………… .10– 20 minutes.
Drain (Drop water).
Wash 1 time by cold water (Wash 1 time by cold water.)
