Some Observations
The construction of original agitator is consisted the upper portion and lower portion.
The lower portion has 4 semi-flexible fins, that work like a vane pump, to drive water from centre towards the side near the bottom, along the side and up to the top.
Then water at the top moves towards centre.
Then water at centre moves from top to bottom to the centre of the fins.
The water moves in a circulation and the laundry in the tub will be circulated as the flow of water.
The upper portion of the fin has 4 Angel wings and 8 small fins (ridges).
The 8 samll fins will rub against the laundry near the centre (a rubbing action to clean the laundry).
The 4 Angel wings would also provide a more powerful rubbing action which may shred/tear the laundry. They also form a pumping action to drive the water/laundry away from the centre. Apparently they interfer the down circulation of the laundry near the centre.
Modified Agitator as shown. The 4 Angel wings were cut to form 4 extra small fins(ridges) for rubbing purpose only. There will be less intrference for down circulation near the centre.
Thus it will reduce the shredding effect and inrcease the turn-over the laundry.
I think it would behave similar to an earlier version (without Angel wings)
Results.
Lesser lint deposited on the lint filter of the dryer.
lesser lint (or light color residue) marks on the dark color laundry.
The attached photo shows a home-made lint filter for the modified agitator. The filter is made of stainless steel screen and will be placed inside the centre pole. Water will enter the holes and down the pole due to pumping action of the 4 bottom fins. It works and collect some shredded lint from the laundry.
