TLP
SOFT
(BIO POLISHING ENZYME)
INTRODUCTION:
TLP
SOFT is a
technically advanced Enzyme system for the cotton fabric / garment finishing
industry . The active ingredients of TLP SOFT are cellulolytic enzymes obtained
by the fermentation of non – pathogenic moulds of the Trichoderma species.
TLP SOFTis used in the finishing of Cotton , Viscose , Jute , Flax ,
Polynosics , Ramje , Tencel to produce a range of Bio – finished effects.
The product is suitable for Bio polishing of Cotton twills ,
Chinos , Knits etc fabrics / garments and also in low mechanical friction wet
processing textile machinary's.
ADVANTAGES
OF USING ENZYMES:
| 1. |
High Dose Response TLP SOFT has a high dose response
which provides the flexibility of varying dose , pH temperature and time to
achieve a wide range of abrasion from light to heavy.
|
| 2. |
Compatibility With Auxillary Chemicals TLP SOFT is
compatible with most other processing aids , including Non-ionic surfactants ,
Dispersing agents , Pumice stones , Abrasive powder , Diatomaceous earth etc.

APPLICATION:
In Fabric Finishing Applications , the enzyme creates
an improved hand increases softness , eliminates dead and immature Cotton ,
removes surface fibers , and prevents pill formation on cellulosic fabric.
In Garment Finishing Applications , the enzyme
treatment can be used for general bio polishing to remove surface hairyness and
impart a clean and highly polished surface. Bio polishing treatment can be given
prior to dyeing or after dyeing treatment after dyeing results in partial
removal of dye and softens the fabric . While treatment before dyeing improves
the colour yield along with the hand feel.
PROCESS CONDITIONS: Enzymatic “Bio Polishing” comprises of three main steps :
DESIZING/PRE WETTING
BIOPOLISHING
FINISHING
DESIZING
:
Proper and complete desizing is required for consistent performance in case of
Denims. In case of other cotton fabrics proper stripping of finishing chemicals
should be done with suitable wetting agent or 0.1 % HCL . M.L's DEL DESIZING
is recommended for the removal of starch sizing materials. In case of Non-Denims , Prewetting is recommended before Bio
finishing.
BIOPOLISHING
:
On completion of Desizing the Liquor is drained and rinsed once with plain
water. The fabric / garment is then steeped in water at a ratio of approximately
10 : 1 and the temperature of the water is then raised to 55 Deg C ( 131 Deg F )
and the pH of the water is adjusted to 4.5 with Acetic Acid .
TLP SOFT is then dosed at a recommended level of 0.5 to 1 % based on fabric / garment weight. Biowashing is then carried out for a
period of 45 to 90 minutes depending on the effect desired ensuring that the
temperature is maintained between 50 to 55 Deg C. It is imperative to ensure that the temperature does not exceed 55 Deg C ( 131
Deg F ) in order to prevent destabilization of the Enzyme system.Non – Ionic wetting Agents may be added in conjunction with
Enzymes in order to enhance the performance of Enzymes

FINISHING
:
At the end of Biopolishing which is evaluated by the required appearance, removal of surface protruding fibre , the liquor is drained and the fabric /
garment is rinsed atleast twice with plain water to remove the surplus dye .The
fabric / garment is then washed with a mild detergent for approximately 5
minutes. At the end of this wash , the liquor is drained and the material is
rinsed with plain water followed with a 5 minutes wash with an optical
brightener and a suitable softener .PACKING
:
TLP
SOFT is available as off white coloured
powder in standard 25 Kgs HDPE Drum.
STORAGE
AND HANDLING :
TLP
SOFT should be stored in preferably
cool and dry place. Care must be taken to ensure that
the containers are kept closed after use to prevent
moisture entry into the product. Other handling instructions
are available on request.
SHELF LIFE :
TLP
SOFT is stable under recommended storage
conditions for a period of 6 months with less than
10% drop in activity. M.L.’s standard assay
method for cellulase activity is available on request.
