TABLE 1.

Anti-SARS-CoV-2 activity of C-POLAR-treated spunlace

C-POLAR concentration (wt/wt%)	Contact time (min)	Cellulose/polyester-based textile
C-POLAR concentration (wt/wt%)	Contact time (min)	SARS-CoV-2 titer reduction (%)^a	P value^b
4%	5	68 ± 4.6	<0.0001
4%	30	81 ± 2.8	<0.0001
6%	5	98 ± 1.6	<0.0001
6%	30	99.6 ± 0.004	<0.0001
8%	5	78 ± 5.2	<0.0001
8%	30	89 ± 8.3	<0.0001

^{^a}

SARS-CoV-2 titer reduction was calculated from average SAR-S-CoV-2 titers from untreated textile set as 100% minus the quotient between averages from SARS-CoV-2 titers from C-POLAR-treated and untreated textiles. Results are reported as mean and standard deviation expressed in percentage from three biological replicates.

^{^b}

One-way analysis of variance test between SARS-CoV-2 titers determined from untreated versus C-POLAR-treated textiles at given contact time.
