The volume density indicators of the two-layer knitted fabrics of the new structure
were determined and found by the following formula:
δ = М
s
/ Т (2)
δ - volume density of knitted fabric, mg/cm

;
М
s
- surface density of knitted fabric, g/m

;
Т - thickness of knitted fabric, mm.

The change values of the absolute and relative lightness indicators of the two-layer
knitted fabric in the new structure are presented below (Fig. 4).
After researching the technological parameters of the two-layer knitted fabric
samples produced in the new structure, it is possible to come to the conclusion that
the change in the ratio and structure of the fabric due to the interlocking arrangement
of the needles of the flat-needle knitting machine during the production of the knitted
fabric has been found to affect its technological parameters. As a result, it was found
that the parameters of raw material consumption of two-layer knitted fabrics of the
new structure IV and V in comparison to the base fabric are lower among fabric
samples.
