Put back ripped percale (7)
I believe the answer is:
replace
'put back' is the definition.
(I know that put back can be written as replace)
'ripped percale' is the wordplay.
'ripped' is an anagram indicator (I've seen this in other clues).
'percale' anagrammed gives 'REPLACE'.
(Other definitions for replace that I've seen before include "Put something back where it belongs" , "Put back or substitute" , "Substitute for (someone)" , "Provide a substitute for" , "Substitute, supplant" .)
