This study describes the Spike Recovery of all 24 Banned Amines by following the European standard EN 14362. The work is carried out by directly using the standard Banned Amines and not with the azo colorants. We can see the poor recovery of some of the amines due to their poor stability and their further reaction in an extraction process.

Adhesion Studies of Atmospheric Pressure Plasma Treated Nylon66 Fabrics with Polyurethane

Dr. Shital Palaskar
Plasma treatment of nylon fabric was carried out with aim of improving the adhesion properties with polyurethane polymer. The effect of the plasma parameters vis. treatment time and power on adhesion improvement were examined. The force required to separate the coating from the fabric was measured as a peel-off strength of the coated fabric.
