AVCO-BIOLUZE DCB is a special product for dyeing of cotton, cotton blends and polyester fabrics without pretreatment.
AVCO-BIOLUZE DCB can remove paraffins, oils, fats and other impurities found on the textile material, and keep it suspended in the dyeing liquor, without interfering the dyeing process. These properties enable one-step scouring-dyeing without pretreatment.
AVCO-BIOLUZE DCB is composed of biodegradable ingredients with no potential for bio-accumulation, and with no evolution of toxic compounds during biodegradation.
AVCO-BIOLUZE DCB is environmentally acceptable, and can be regarded as a “GREEN” product.

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.
- Stable to high temperature, even at H.T. conditions.
- Does not contain any hazardous solvents.
- Low foaming, can be used in jet machines.
- Has no retarding effect on reactive, vat, direct and disperse dyestuffs.
- Good stability towards concentrated electrolytes as used in cotton dyeing.
- AVCO-BIOLUZE DCB is very versatile. Due to its excellent detergency it can be
used in many wet processes such as bleaching, pretreatment, machine cleaning,
soaping etc.
APPLICATION:
AVCO-BIOLUZE DCB should be pre-mixed with cold or warm water, at ratio of 1:3 before use. Following are some typical application procedures:
- Cotton knits “One-Step” dyeingAdd to the machine 1-2 g/l AVCO-BIOLUZE DCB, for heavily soiled knits use 2-3 g/l of the product. The textile material should be treated for a period of 5 minutes with AVCO-BIOLUZE DCB before the addition of the dyestuffs and auxiliaries.
The dyeing process should be carried out as normal.
- Polyester and polyester blends “One-Step” dyeing
Usage of 1-3 g/l of AVCO-BIOLUZE DCB is recommended.
The textile material should be treated for a period of 5 minutes with AVCO-BIOLUZE DCB before addition of the dyestuffs and auxiliaries.
- Peroxide bleaching
Use 0.5 – 1.5 gr/l of AVCO BIOLUZE DCB for pre-scouring cotton and polyester-cotton fabrics before peroxide bleaching. It is very effective to pre-scour for 10 minutes with AVCO-BIOLUZE DCB and to continue peroxide bleaching in the same liquor.
- Reductive bleaching
Improvement of whiteness and absorbency of cotton fabric, can be achieved with
AVCO-BIOLUZE DCB. After the peroxide bleaching stage continue with a reductive bleaching step. Use the following recipe:
AVCO-BIOLUZE DCB 1 – 3 g/l
Sod. hydrosulphite 2 – 4 g/l
Treat at 80° C, for 20 minutes.
- Cotton lycra fabrics
AVCO-BIOLUZE DCB is an excellent detergent for preparation and bleaching of cotton
lycra fabrics. For pre-wash use 1-2 g/l AVCO-BIOLUZE DCB and 2 g/l soda ash.
For bleaching add 0.5-1 g/l AVCO-BIOLUZE DCB to the bleaching recipe.
- Dyestuff stripping
Use 2-3 gr/l together with hydrosulphite and caustic soda.
- Machine cleaning
Use 2-3 g/l AVCO-BIOLUZE DCB together with hydrosulfite and caustic soda.
