Claim 0:
1. A weaving machine comprising:
a yarn winding mechanism for winding and unwinding undyed yarns;
a yarn coloring mechanism for receiving the undyed yarns and for dyeing the undyed yarns using a water-free dyeing technology of sublimation transfer printing, said yarn coloring mechanism including:
a hot roller,
an inner layer color paper tape winding device for unwinding an inner layer color paper tape from one end thereof to be wound to the other end thereof after looping over said hot roller, said inner layer color paper tape movably abutting against an outer surface of said hot roller and being configured to be pressed by the undyed yarns,
an outer layer color paper tape winding device for unwinding an outer layer color paper tape from one end of said outer layer color paper tape winding device to be wound to the other end of said outer layer color paper tape winding device after looping over said hot roller, said outer layer color paper tape being configured to movably abut against the undyed yarns, said inner layer color paper tape and said outer layer color paper tape being configured to clamp therebetween the undyed yarns,
a packing paper winding device for unwinding a packing paper from one end of said packing paper winding device to be wound to the other end of said packing paper winding device after looping over said hot roller, said packing paper movably abutting against said outer layer color paper tape, and
a squeezing device including a closed loop belt movably pressing said packing paper against said hot roller such that inks carried by each of said inner layer color paper tape and said outer layer color paper tape are sublimated by heat of the hot roller and transferred to the undyed yarns and thereby dye the undyed yarns; and

a back-end system configured to receive the dyed yarns and configured to weave or wind the dyed yarns.
