METHOD FOR PRODUCING OF MULTIPLE-COLOR PILE PATTERNS Russian patent published in 2005 - IPC

FIELD: textile industry, in particular, finishing of articles and materials for various purposes with pile patterns by electric flocking process.

SUBSTANCE: method involves producing patterns of predetermined shape by forming pile pattern at zone separation boundary provided that separation boundary potential is equal to U₁-Uh₁/h, where U is potential of upper boundary of flocking zone, h₁ is height of lower flocking zone, h is height of entire flocking zone. This is provided by sequentially applying piles of different color in electric field divided into two zones in vertical plane, with electric field intensity during final application process carried out in homogeneous field having one zone being set equal to that of the entire space of both zones by setting potential of boundary separation zone equal to U₁=Uh₁/h, where U is potential of flocking zone upper boundary, h₁ is height of flocking zone lower boundary, h is height of the entire flocking zone.

EFFECT: provision for producing of patterns of predetermined shape.
