I am interested to know if there is any particular kind of knitting in
which we can "Dis Knit" the fabric by pulling out its thread and when
we keep pulling out the thread continues to pull out in the same
motion until the whole fabric converts back thread like it was before
being knitted?

hint: sometimes in socks or some garments, you can seethat when we
pull out a thread it keeps pulling out.

I believe that any regular knit fabric can unravel as you describe.  A
single knit stitch is like a slip knot--if you pull on it, it goes
back to a straight thread.  (There are actually two stitches, called
"knit" and "purl."  But one is just the other done backwards.)  A knit
fabric is a giant sequence of slip knots connected to each other.  The
last row is tied off so that it won't unravel.  However, if you were
to cut or pick apart the real knots in the last row, you could unravel
the whole thing.  Check any website with instructions on knitting, try
it out, and you'll find that the result will unravel quite easily.
