LOW FOAMING DETERGENT

AVCOBLANK JET is an highly concentrated surfactant composed of a blend of emulsifiers and detergents. The product has low foaming properties even in boiling bleaching bath.
AVCOBLANK JET can be used as a scouring agent, bleaching and dyeing auxiliarry for preparation and dyeing of fibres, hanks, packages and fabrics made from cellulosic and synthetics fibres.
AVCOBLANK JET is a multifunctional detergent with wetting, emulsifying and dispersing properties. It is very effective for removing silicone and hydrocarbon lubricants from textiles.
AVCOBLANK JET is recommended for pre-treatment processes in high speed jets and in high speed continuous ranges.
AVCOBLANK JET is composed of biodegradable ingredients with no potential for bio-accumulation, and with no evolution of toxic compounds during biodegradation.

SPECIFICATION:

Appearance	Almost colorless clear liquid, slightly viscous.
Chemical nature	lend of alkoxylated surfactants and solubilizers.
Compatibility	Compatible with nonionic, cationic and anionic dyestuffs and auxiliaries.
Ionic activity	Nonionic
pH of 1% solution	6-8
Solubility	Emulsifiable in water in all proportions.
Storage	Becomes viscous at freezing temperatures, fully usable after thawing. Shelf life is at least 12 months.

PROPERTIES & USES:

Excellent detergency, wetting, emulsifying and dispersing properties.
Good soil suspending properties, which can prevent any re-deposition
of soil on dyed fabric through all dyeing cycle.
Very good emulsifier towards oils and lubricants which contained in
raw fabrics and yarns. Highly recommended for removing texturizing
oils , knitting oils, “sulzer” loom oils and silicone lubricants
from all kind of fibres.
Stable to high temperature, even at H.T. conditions.
Very low foaming, recommended for jet machines.
Good stability towards electrolytes as used in cotton bleaching and dyeing.
AVCOBLANK JET is very versatile. Due to its excellent detergency it can be used
in many wet processes such as
scouring, bleaching, dyeing , soaping etc.

APPLICATION:

Due to its wide versatility, AVCOBLANK JET has a number of important uses for scouring and dyeing as follows:

I. Cotton and blends:

AVCOBLANK JET is recommended for all types of preparation and

bleachingprocesses of textiles composed of cotton

and blends with synthetics.

Following are dosage recommendation for various processes:

¨ Alkaline pre-treatment 0.3 – 2.0 g/l

¨ Pre – scouring 0.3 – 2.0 g/l

¨ Bleaching 0.3 – 2.0 g/l

¨ Dyeing 0.2 – 0.6 g/l

¨ Scouring knits containg spandex/lycra 0.5 – 2.0 g/l

II. Peroxide bleaching of cotton and cotton blends1. Fill machine with water and add chemicals:

AVCOBLANK JET 0.3 – 2.0 g/l

AVCOSLIP LB (anticreasing agent) 1.0 – 2.0 g/l

2.Load fabric and treat for 5-10 minutes.

3. To the same liquor add the bleaching auxiliaries, and start the bleaching process.

Use the following recipe for full bleach:

AVCO-STABILIZER HSF 0.5 – 1.5 g/l

H₂O₂ (50%) 6.0 – 8.0 g/l

AVCOLUX CBA-100 0.5 – 1.0 %

4. Treat for 45-60 minutes at 90-95C, followed by hot and cold rinse.

III. Polyester and blends

AVCOBLANK JET can be used in jet dyeing machines as one

bath scour/dyeauxiliary. A typical cycle for bulked polyester piece goods isas

follows:

1. Load the machine, run for 3-5 minutes to remove water soluble and emulsifiable matter and drop the bath.

2. Add a sequestering agent ( AVCOTRYL HPH) and adjust the bath to pH 5-5.5

3. Raise temperature to 40÷C, add AVCOBLANK JET (0.3-1 g/l) and a levelling agent(AVCONAL PLD).

4. Increase temperature to 60÷ C and add the dyestuffs.

5. After circulating, raise temperature to 125-130÷ C and dye to shade.

IV. PolyamideAVCOBLANK JET can be used effectively for the scour/dyeing of bulked

polyamidestockings and other polyamide articles.

Dosage recommendation:

¨ Scour/dyeing bulked polyamide hosiery

Use: 0.5-1.5 g/l

¨ Scour/dyeing micro fibre knits in jet machines

Use: 0.5-1.5 g/l.

V. Polyamide blends with spandex/lycra

AVCOBLANK JET is highly recommended for removing silicone lubricants and knitting oils from polyamide knits containing high percentage of spandex yarns.1. Fill machine

2. Add the chemicals:

AVCOBLANK JET 0.5 – 1.0 g/l

AVCOTEX HSP0.5– 1.0 g/l (high speed penetration accelerant)

AVCOSLIP PAS 1.0 – 2.0g/l

AVCOTRYL PN 1.0 – 2.0 g/l

SODA-ASH 1.0 – 2.0 g/l

3. Load fabric and treat at 80-90c for 20-40 min.

4. Drop bath and rinse hot and cold.

VI. Pretreatment of cotton knits containing spandex/lycra

AVCOBLANK JET1.0 – 2.0 g/l

AVCOTEX HSP1.0 – 2.0 g/l (high speed penetration accelerant)

AVCOSLIP PAS 1.0 – 2.0 g/l
