Abstract
Abstract Textile material to be dyed is circulated through a dyeing machine containing a hot liquid dye bath in such manner that the material repeatedly is immersed in and removed from the dye liquor. Following removal of the material from the dye liquor it is subjected to treatment by air to remove surplus liquid from the material prior to the return of the material to the dye liquor. Following its final removal from the dye liquor the material is cooled by being sprinkled with water at a temperature lower than that of the dye liquor.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
100 words
A process for the wet treatment of textile material comprising introducing said material to a treatment chamber containing a bath of hot treatment liquid; repeatedly immersing and removing said material in and from said liquid; subjecting said material to treatment by air following each removal of said material from said liquid to remove surplus liquid from said material; moving said material out of said chamber following a final air treatment; and spraying onto said material a fluid having a temperature lower than that of said liquid to cool said material prior to passage of said material out of said chamber.
Claim 2
Dependent Claim
100 words
A process for the wet treatment of textile material comprising introducing said material to a treatment chamber containing a bath of hot treatment liquid; repeatedly immersing and removing said material in and from said liquid; subjecting said material to treatment by air following each removal of said material from said liquid to remove surplus liquid from said material; moving said material out of said chamber following a final air treatment; and spraying onto said material a fluid having a temperature lower than that of said liquid to cool said material prior to passage of said material out of said chamber.
