ABSTRACT:
One or more dye fixation combs are mounted within a high temperature dye fixation steamer housing downstream from the yarn dyeing device and a post steamer and upstream of a coiler which places the yarn in coil form onto a conveyor for subsequent operations in a dye line. The yarn is fed in warp form through the high temperature steamer. Each comb has a series of spaced apart fingers extending from the body of the comb. The body of the comb is hollow and defines a conduit. Between each pair of fingers at the location of the comb body is a root having an orifice communicating with the conduit. A strand of yarn is directed through each root guided by a pair of support rods, one of which is upstream of the comb and the other of which is downstream of the comb. The yarn is under tension and is directed against the outlet of the orifice. A source of superheated steam is supplied to the conduit so that each yarn strand as it moves in warp form through the steamer is impinged upon by steam above 212.degree. F.
