a sixth shuttle: lifting the second warp yarns on the upper layer upwards; lifting the first warp yarn of the lower layer upwards; lifting the second pile warp yarns upwards, and sinking the first pile warp yarns downwards; throwing the sixth weft yarns on the upper layer and the sixth weft yarns on the lower layer, and beating up and weaving;
B. take a two-terry loop fabric as an example:
a first shuttle: lifting the tenth warp yarn and the twenty-first warp yarn upwards, and lifting the tenth terry warp yarn upwards; throwing eleventh weft yarns for long-beat-up weaving;
a second shuttle: lifting the tenth warp and the twenty-first warp upwards; lifting the twenty-third terry warp yarn; throwing a twelfth weft yarn to carry out short beating-up weaving;
a third shuttle: lifting the twentieth warp yarn and the eleventh warp yarn; lifting the tenth terry warp yarn; throwing a twelfth third weft yarn to carry out short beating-up weaving;
a fourth shuttle: lifting the twentieth warp yarn and the eleventh warp yarn; lifting the twenty-third terry warp yarn; throwing a fourteenth weft yarn to carry out long-beat-up weaving;
a fifth shuttle: lifting the twentieth warp yarn and the eleventh warp yarn; lifting the tenth terry warp yarn; throwing a fifteenth weft yarn to carry out short beating-up weaving;
a sixth shuttle: lifting the tenth warp and the twenty-first warp upwards; lifting the twenty-third terry warp yarn; and sixteenth weft yarns are thrown in for short beat-up weaving.
6. The method of claim 3, wherein the pile and pile consolidation fastness is increased by: after the fifth step, the pre-shrunk warp yarns have no shrinkage, and the non-pre-shrunk warp yarns are shrunk according to the normal shrinkage, so that the shrinkage is 8-14%, and the non-pre-shrunk warp yarns are pre-shrunk to form the difference between the tight warp yarns and the loose warp yarns, wherein the tightness ratio is 1: 0.9.
