There is a custom to bury a dead person with a kittel. It is also customary for men to wear a kittel in shul during the High Holidays.
Let's say a dead body is exhumed. In Israel, it is common to bury the body without a casket. When they remove the body, they discover that the kittel is torn to the point where a significant part of the body is uncovered. They remove the old kittel, and cover the body with a new one prior to revurial.
Does this old kittel maintain some type of holiness, or can a family member repair it and reuse it?
Note I am assuming that a torn kittel may or need to be removed out of respect to the dead person. If it cannot be removed, please inform.
