Advantages

• Kohan wet OK is a wetting and scouring soap for continuous systems; usable during scouring and bleaching processes to remove oils, waxes, and pectin from cotton. It also prevents impurities redeposition on the fabric.
• It has excellent enhancing hydrophilicity and color fastness, while also increasing fabric whiteness.
• Stable properties in sodium hydroxide up to 15° Baumé and also usable at 20° Baumé, only continuous mixing is required.
• Usable as leveling agent in dyeing process.

Application

• The dosage in bleaching baths varies depend on the system type, machinery, and continuous contact time which are influenced by fabric density, transport speed, dwell time in the foulard.
• The recommended dosage for scouring stage of cotton product: 0.3 g/l
• The dosage of scouring stage using a jigger: 1–3 g/l. (2 g/l ensures excellent dye penetration).
• The dosage of scouring stage using a Haspel machine: 0.5–1 g/l.
• In bobbin dyeing 10-20 g/l is enough.

• Liquid Sodium Hydroxide 50%     10–20 g/L
• Hydrogen Peroxide 50%                25–40 g/L

Should be processed at 100℃ in a continuous steaming chamber for 10-20 minutes.

Kohan Wet OK becomes cloudy in sodium hydroxide up to 5° Baumé. (no negative effect on quality).

the alkalinity and peroxide levels must be continuously titrated and monitored.

Water hardness should be adjusted to DH5 by adding 0.2 g/l of magnesium sulfate.
