The Yangian generators are constructed from two non-commuting su($n$)-loop algebras. The latters generate an infinite dimensional symmetry algebra which is a deformation of the $W_\infty$-algebra. We show that this deformed $W_\infty$-algebra contains an infinite number of Yangian subalgebras with different deformation parameters.8 pages, latex, 1 figure, to appear in the Proceeding of 6-th Nankai WorkshopHigh Energy Physics - Theorytext
