Flock is a textile surface with electrostatic bonding of polyamide fibres which are fine and very short, giving the fabric the appearance of suede.
Tannic acids are widely used for the electrostatic activation of nylon fibres together with aluminium salts.
Silvateam has developed a wide range of products called Tannin Flock, to meet the requirements of its customers. Tannin Flock is made of tannic acid, in powder form, for the activation of polyamide and polyester flock. Their main characteristics are the good conductivity and stabilisation of electrostatic activity.
