Abstract:
The present invention relates to a dyeing bobbin having assured dyeing efficiency and a sliding structure, the dyeing bobbin having a sliding structure and a cut portion so as to impart elasticity thereto in order to respond to the expansion and contraction of yarn that occurs in the process of dyeing yarn wound around the bobbin, thus preventing the occurrence of stains due to the leakage of salt water and the like during high-pressure dyeing, and the dyeing bobbin comprising: an annular upper cap (10); an annular lower cap (20) provided below the upper cap (10) to be spaced apart therefrom; a support (30) formed to connect the upper cap (10) and the lower cap (20) in an integrated form; and coil-shaped elastic body (40) connected and fixed to the support (30) along the inner circumferential surface thereof, wherein, by cutting a portion having some length on the rim of the upper cap (10), an elastically moving part (12) is formed.
