Method of dyeing treatment for a fabric and apparatus therefor

摘要

A method of dyeing a fabric connected in an endless form while repeatedly circulating said fabric through a dyeing tank is improved by providing a residence vessel made of a perforated plate within said dyeing tank and either rocking or vertically reciprocating said residence vessel as immersed in a dyeing liquor while said fabric is being stagnated within said residence vessel. Owing to the rocking or vertical reciprocating motion of the residence vessel, the dyeing liquor is made to flow into and out of said residence vessel, penetrating therethrough, and thereby the necessary amount of the dyeing liquor can be reduced and the dyeing time can be shortened. A desirable apparatus for practicing said improved method is also provided.
