You don't say whether your DH has always interfered in the laundry, or whether it is a new thing due to him having recently retired. If it is the first, then probably you cannot get him to agree to the following, but if he has recently retired this might help.
Sit him down and tell him that you would prefer to be left to do the washing, drying and ironing of all clothes, towels and bed linen yourself, but you would greatly appreciate him doing other tasks.
Ask him which jobs he would prefer to do and let him do them.
The only snag here is that if his hoovering and dusting are as bad as his laundering, it will probably drive you mad.
The only other solution is, if you are so well-off that you can pay for help in the house. I'm sure your husband will see the point of not doing jobs your cleaner is paid to do.
If his behaviour is not due to transitioning to retirement, I am afraid those who mention dementia might be right.
