RULE - I
The further apart the two materials are in the series the more easily static
is generated.
RULE - II
The material on top is positive with respect to the material below it,
which is negative.

HYDROSTATBM LIQUID Nonionic polymeric product
Coats the fibre and hence produces fluffiness in the fabric
Reduces friction
Lowers attraction between fibres and also reduces dust attraction.
In case of fluff forming operations like Bio-polishing and bath mattreatments, reduces the fluff accumulation on the fabric surface. Thecoating aids dispersion and colloidal suspension of the fluff.
Hydrostat BM Liquid when used along with Zycol Floc Liquid in subsequentwashing after enzyme treatment, enhances quick flocculation ensuringcomplete fluff removal.
Application Method
Padding HydrostatBM Liquid 5 - 20 gms/lit
Pad with 70% pick-up and dry at 180C for 45 secs.
Exhaust Hydrostat BM Liquid 1.0 - 3.0 %
Treat at 50 - 70 C and pH 5.5 6.0 for 20 - 30 mins.

ANTI-STATIC EFFECT
By definition, static is a relativelyimmobile electric charge on a surfaceand commonly known as electrostaticcharge In a fiber-finish-guide surface
system, three factors can be seen ascontrolling factors in generation of suchcharges. These are
Charge transfer during surface contact
Charge leakage across gap
Charge flow along the surface
The speed of electrostatic chargedissipation from the surface of polyesterfiber has been characterised forHydrostat BM.
