Disclosed herein is a fiber treating process which comprises treating fibers. An ester formed by the union of an polybasic carboxylic acid and a compound represented by the formula below ##STR1## where R.sub.1 and R.sub.2 represent C.sub.4 -C.sub.18 alkyl groups; AO represents a C.sub.2 -C.sub.4 alkyleneoxide group; and n represents an integer of 0 to 30.

Fiber treating process and composition used therefor

A residual fuel oil is improved in dispersion stability when a large amount of sludge is contained therein and comprises (1) a thermal cracking oil, (2) a diluent and (3) a dispersant selected from the group consisting of (A) an imidazoline derivative containing a hydrocarbon group having 7 to 23 carbon atoms, (B) a hydrolysis product of (A), (C) a reaction product of an aliphatic acid having 8 to 22 carbon atoms and a polyalkylenepolyamine having 4 to 6 amino groups, (D) a monoamine containing a hydrocarbon group having 8 to 22 carbon atoms, (E) a polyamine containing a hydrocarbon group having 8 to 22 carbon atoms, (F) an etheramine having a long chain hydrocarbon group, (G) a phosphate having a long chain hydrocarbon group, (H) a salt of (G), (I) a dithiophosphate and (J) a salt of (I).
