No, the creature will not die.
The rules for determining whether creatures die due to damage are part of state-based action, which are checked every time a player would gain priority:
704.5g If a creature has toughness greater than 0, and the total damage marked on it is greater than or equal to its toughness, that creature has been dealt lethal damage and is destroyed. Regeneration can replace this event.
704.5h If a creature has toughness greater than 0, and it’s been dealt damage by a source with deathtouch since the last time state-based actions were checked, that creature is destroyed. Regeneration can replace this event.
As you can see, deathtouch damage is only handled once, the first time state-based actions are checked after the damage is dealt. So, in your situation, the creature takes the 1 deathtouch damage. Then, immediately after that, state-based actions are checked, 704.5h applies, and it tries to destroy the creature, but the creature is indestructible, so nothing happens. Later, after you remove the equipment, state-based actions will be checked again, but the creature hasn't taken damage from a source with deathtouch since the last time state-based actions were checked, so the rule doesn't apply and nothing happens.
