DETAILED DESCRIPTION

[0059] FIG. 1a shows a combined lapping of a laminar velour knitted fabric according to the invention with two lappings of the base yarn 1a, 1b and 2a, 2b as well as one lapping of the pile yarn 3a, 3b. For each single lapping, 5 individual yarns are shown. The combined lapping consists of a satin-fringe-satin lapping. The first lapping bar knits a closed satin lapping (see 1a, 1b), the second lapping bar knits an open fringe lapping (see 2a, 2b) and the third lapping bar knits a closed satin lapping (see 3a, 3b). The open fringe lapping of the base yarn blocks the satin lapping of the pile yarn, which means that the pile yarn cannot escape during subsequent raising and thus an optimum surface finish of the pile can be provided with high efficiency.

[0060] In FIG. 1b, the combined lapping from FIG. 1a is shown, but only one single yarn is shown per lapping for a better overview.

[0061] FIG. 2a shows a combined lapping of a laminar velour knitted fabric according to the invention with two lappings of the base yarn 1a, 1b, and 2a, 2b. In addition, the combined lapping comprises a further lapping of the pile yarn 3a, 3b. For each single lapping, 5 single yarns are shown. In contrast to the combined lapping shown in FIGS. 1a and 1b, the combined lapping consists of a satin-fringe-velvet lapping. By comparison with the combined lapping in FIGS. 1a and 1b, it is clear that after the raw knitted fabric has been napped, i.e. after the velvet lapping of the pile yarn has been cut, a pile with longer individual fibrils is produced than in a satin-fringe-satin lapping.

[0062] FIG. 2b shows the combined lapping of FIG. 2a, but only one single yarn 1a, 2a and 3a is shown per lapping.

[0063] FIG. 3 shows a top view of the bottom side 11 of a velour knitted fabric 10 according to the invention. The bottom side 11 comprises a knitted fabric of a pile material, which is formed as a pile yarn 3, and of a base material, which is formed as a first base yarn 1 and a second base yarn 2. Due to the very tight knitting, the pile yarn 3 is firmly anchored in the knitted fabric so that the individual fibrils of the pile are firmly anchored in the knitted fabric on the averted top side of the velour knitted fabric and do not disengage from the velour knitted fabric even without additional adhesive. For example, a polyester yarn dtex 33F15 can be used as the base yarn and a polyester yarn dtex 78F300 as the pile yarn.

[0064] FIG. 4 shows the top side 12 of a raw knitted fabric according to an embodiment of the invention. The surface of the top side 12 consists essentially of pile yarn 3, or is formed from it. Since the raw knitted fabric has not yet been napped and thus the pile yarn on the top side has not yet been cut, the pile has also not yet been formed.
