Determination of Knitted Fabric Porosity Using Digital Imaging Techniques

Table 7

Linear regression equations—for the different features for the CKM knits.

(a)

Fabric features	Single jersey	value
Tightness factor, stitch length (SL)	TF = −0.372 (SL) + 3.966	0.993

(b)

Fabric features	⁢Single jersey
	White mask	value	Black mask	value
% P, SL	% P = 5.75 (SL) + 30.65	0.923	% P = 8.707 (SL) + 19.42	0.888
% P, SD	% P = −0.473 (SD) + 62.28	0.912	% P = −0.736 (SD) + 67.79	0.926
% P, TF	% P = −15.61 (TF) + 92.31	0.952	% P = −23.81 (TF) + 113.2	0.930
