  YBCO fabrics composed of nanowires, produced by solution blow spinning (SBS)
are so brittle that the Lorentz force produced by induced currents can be
strong enough to damage them. On the other hand, it is known that silver
addition improves the mechanical and flux pinning properties of ceramic
superconductors. Thus, in this work, we show how we successfully obtained a
polymeric precursor solution containing YBCO$+$Ag salts, which can be spun by
the SBS route to produce ceramic samples. Yttrium, barium, copper, and silver
metal acetates, and polyvinylpyrrolidone (PVP) (in a ratio of 5:1wt
[PVP:acetates]) were dissolved in a solution with 61.5 wt\% of methanol, 12
wt\% of propionic acid, and 26.5 wt\% of ammonium hydroxide, together with 6
wt\% of PVP in solution. Three different amounts of silver (10 wt\%, 20 wt\%,
and 30 wt\%) were used in YBa$_2$Cu$_3$O$_{7-x}$. The TGA characterizations
revealed a lowering of crystallization and partial melting temperatures by
about \SI{30}{\celsius}. SEM images show that after burning out the polymer, a
fabric composed of nanowires of diameters up to \SI{380}{\nano \metre} is
produced. However, after the sintering process at \SI{925}{\celsius} for
\SI{1}{\hour}, the nanowires shrink into a porous-like sample.
