METHOD FOR PRODUCING OF MULTICOLOR PILE PATTERNS Russian patent published in 2007 - IPC D04H11/00 

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

SUBSTANCE: method involves sequentially applying piles of various colors in electric field divided, according to pile advancement direction, into two zones: initial and final; finally applying piles in homogeneous field having one zone; simultaneously varying electric field intensity during all application stages except for final stage, said variations being provided simultaneously at initial zone within the range of from E_i=(U-U₁)/(h-h₁) to Ei≈0, and in final zone after passage by piles of interface boundary within the range of from E_f=(U₁-U₀)/h₁ to E_f=(U-U₀)/h₁, by setting zone interface boundary potential from U₁=(U-U₀)h₁/h to U₁=U, where U potential of outer boundary of flocculation initial zone; U₀ is potential of outer boundary of flocculation initial zone; h₁ is size of final flocculation zone in direction of advancement of pipe; h is total size of both flocculation zones in direction of advancement of piles.

EFFECT: wider range of adjustment of pattern shapes and distinctness of color transition sites owing to formation of pile pattern by varying of electric field intensities.
