Solvent dyeing and heatsetting apparatus

摘要

Textile fabrics are dyed in open widths in a closed, heated environment by spraying a heated dye composition containing a dyestuff dispersed in a non-aqueous, high-boiling solvent, without the dye applicator directly contacting the fabric, directly onto the fabric. The sprayed fabric is held under transverse tension in a heated (350 DEG to 450 DEG F.) environment and further heated while the sprayed dye dispersion migrates, penetrates thoroughly through the fabric and levels substantially evenly across the width of the fabric. Fabrics are thus simultaneously uniformly dyed and uniformly heatset. Apparatus for conducting the process is also disclosed.
