Determination of Knitted Fabric Porosity Using Digital Imaging Techniques

Table 6

Linear regression equations: % porosity against stitch length (FKM samples).

Fabric features	Structures	White mask	value	Black mask	value
% porosity (), stitch length (SL)	Plain	% P = 1.509 (SL) + 33.88	0.989	% P = 0.711 (SL) + 41.65	0.980
	Rib 1 1	% P = 0.426 (SL) + 43.99	0.669	% P = 0.5439 (SL) + 42.99	0.884
	Rib 2 1	% P = 1.551 (SL) + 25.05	0.945	% P = 2.437 (SL) + 11.85	0.924
	Single jersey	% P = 1.763 (SL) + 23.95	0.877	% P = 1.011 (SL) + 34.79	0.864
