Nafissatou Diallo told Newsweek magazine that she has told the truth about the incident on 14 May.
The move comes as authorities consider whether to drop charges against him amid doubts over her credibility.
The French politician, 62, who resigned as head of the IMF to defend himself, vigorously denies all the charges.
He has said that what happened with Ms Diallo was consensual, and his lawyers have described the maid's interview as "unseemly".
Media campaign?
Ms Diallo told Newsweek magazine: "I want him to go to jail. I want him to know there are some places you cannot use your power, you cannot use your money."
The 32-year-old immigrant from Guinea told the magazine that she was scared about losing her job when she eventually ran from the room where the incident allegedly took place.
But Mr Strauss-Kahn's representatives accused her of conducting a "media campaign" to persuade prosecutors to pursue charges against the former IMF chief, Reuters news agency reported.
He is charged with seven counts including four more serious felony charges - two of criminal sexual acts, one of attempted rape and one of sexual abuse - plus three misdemeanour offences, including unlawful imprisonment.
But some US media reports say the case is close to collapse. Court prosecutors have said that the maid gave false testimony to a grand jury, citing inconsistencies in her account of the sequence of events on the day.
Mr Strauss-Kahn was released from house arrest on 1 July and had his $6m (£3.7m) cash bail and bond returned.
Meanwhile, French authorities are investigating allegations that Mr Strauss-Kahn attempted to rape French writer Tristane Banon a decade earlier.
Mr Strauss-Kahn denies any wrongdoing, and has launched a counter-claim, suing Ms Banon for making false statements.
Ms Diallo has also granted an interview to the ABC news network, excerpts of which are due to be broadcast on Monday.
Until she came forward for interview, her name had not been reported by media outlets which normally protect the identities of people who say they have been sexually assaulted.
