In this paper, the authors have investigated the influence of structure parameters of knitted fabric to their loading capability of microcapsule. Three most commonly knitted fabrics, which are single jersey, rib 1x1, interlock have been studied. For every kind of them, three value of loop length have been prepared. It was found that the structure and the loop length of knitted fabrics influenced to coating capability of microcapsules. It seem that loading capability is increased with increasing of loop length for rib 1x1 knitted fabics, when this capability is decreased for interlock fabrics in increasing their loop length. In general, the interlock fabric with loop length of 149 mm/100 stitch, has kept most microcapsule (15 percent in mass) among the inverstigated knitted fabrics.
