AVCO-BIOPAL LFB is a biodegradable nonionic, low foaming surfactant, developed for use in jet machines and rotary washing/dyeing machines with high-speed turbulence as well as for high speed padding operations.
AVCO-BIOPAL LFB possesses excellent wetting, emulsifying and washing effect. It can be used in a wide pH range in textile pretreatment, dyeing and finishing.
AVCO-BIOPAL LFB is composed of biodegradable ingredients with no potential for bio-accumulation, and with no evolution of toxic compounds during biodegradation.
AVCO-BIOPAL LFB is environmentally acceptable, and can be regarded as a “GREEN” product.

FILM PROPERTIES:
- AVCO-BIOPAL LFB is applied for treatments of all kinds of textiles such as
cotton,
rayon and synthetic fibres.
- Detergent for high-speed machines or those with tendency to foam, e.g. jet-
machines,
overflow machine, rotary washing machines and high-speed continuous machines.
- AVCO-BIOPAL LFB is particularly recommended as wetting agent for enzymatic de-
sizing.
The efficiency of the enzymes is not impaired in any way. Penetration of the
textile
material with the de-sizing liquor is accelerated and loosening of the decomposed
starch is facilitated.
- During kier-boiling, AVCO-BIOPAL LFB loosens waxes contained in the grey cotton,
emulsifies them and disperses the pigment soil and decomposition products of the
husks. Staining during kier-boiling is thus avoided.
- Because of its outstanding dispersing and emulsifying properties, AVCO-BIOPAL LFB
is
highly recommended for pre-cleaning, scouring and washing oily and greasy
contaminations.
- AVCO-BIOPAL LFB can be applied in neutral, alkaline or slightly acidic liquors.
