  We present a detailed spectro-polarimetric study of Black hole X-ray binary
4U $1630-47$ during its $2022$ outburst with IXPE and NICER observations. The
source is observed in disk dominated thermal state (kT$_{in}\approx1.4$ keV)
with clear detection of absorption features at $6.69\pm0.01$ keV and
$6.97\pm0.01$ keV from both NICER as well as IXPE spectra, likely indicating a
coupling of disk-wind. A significant degree of polarization(PD) $=
8.33\pm0.17\%$ and polarization angle(PA) $=17.78^{\circ}\pm0.60^{\circ}$ in
the energy range of $2-8$ keV are measured with IXPE. PD is found to be an
increasing function of energy whereas PA remains roughly same within the energy
range. Simultaneous energy spectra from NICER in the range of $0.5-12$ keV are
modelled to study the spectral properties. Furthermore, the spin parameter of
the black hole is estimated with spectro-polarimetric data as
a$_{\ast}=0.927\pm0.001\,(1\sigma)$ which is corroborated by NICER
observations. Finally, we discuss the implications of our findings.
