"The Liberty is our home and needs to be a fortress, which we want it to be for the rest of the season," Rangel told the club's website.
"If you want to stay in the Premier League, your home form is the most important thing. We have had some bad performances at home so far, but we must put them behind us and look to start afresh at the Liberty."
Swansea's next opponents Bournemouth have won three of their last four league matches to move four points clear of the relegation zone in 13th place.
