Replacement for Pile weather strip for windows

I have an old aluminum window panel that holds 2 movable glass plates and screen. The aluminum window frame is mounted on the outside of a wood window. I am painting the window frame and need to replace the pile strip that is broken and worn out. I cannot find a replacement at the stores. The pile weather strip is 5/32" wide at the base which is cloth and about 1/4" height in pile (although worn). I am attaching a photo (filename CSC_5167.jpg) with dimensions and different angles of view. Could you please let me know if you have a replacement for this pile weather strip?
With appreciation,
Jorge
