Abstract
Abstract Inventive considerations have shown that the use of shorter liquid ratios can be realized in the course of wet-treating textile ropes in jet dyeing machines if the textile goods are driven by means of a non-inert gas stream and the dyestuff or product formulations necessary for carrying out the type of treatment desired are brought into contact with the goods by atomization into the circulated gaseous driving agent.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
141 words
In a process for the discontinuous or continuous wet treatment of textile material of synthetic or natural fibers or of mixtures of such fibers in rope form with dyestuffs suitable for the particular fiber type by the exhaust method or with other textile-finishing products on jet dyeing machines, in which the goods are propelled via a jet system by means of a circulated gas stream, the improvement wherein the textile goods are driven by a gas stream which is non-inert in respect of the intended specific treatment effect and, at the same time, the treatment agents or treatment agent formulations are added in an atomized form to this gas stream in the jet section for the goods drive and are thus brought into contact with the textile goods and allowed to act there corresponding to the preselected temperature and pressure conditions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
16 words
The process as claimed in claim 1, wherein the non-inert gas stream is a steam stream.
Claim 4
Dependent Claim
15 words
The process as claimed in claim 1, wherein the non-inert gas stream is hot air.
Claim 5
Dependent Claim
22 words
The process as claimed in claim 1, wherein the non-inert gas stream is a hot gas other than steam or hot air.
Claim 6
Dependent Claim
17 words
The process as claimed in claim 1, wherein the non-inert gas stream is a mixture of gases.
Claim 7
Dependent Claim
19 words
The process as claimed in claim 1, wherein the non-inert gas stream is a mixture of steam and air.
Claim 8
Dependent Claim
18 words
The process as claimed in claim 1, wherein the non-inert gas stream is hot or cold solvent vapor.
Claim 9
Dependent Claim
24 words
The process as claimed in claim 1, wherein the non-inert gas stream is mixed from hot and cold components to give the process temperature.
Claim 10
Dependent Claim
17 words
The process as claimed in claim 1, wherein the textile goods are treated under pure isothermal conditions.
Claim 11
Dependent Claim
20 words
The process as claimed in claim 1, wherein the textile goods are treated in several isothermal stages of different temperature.
Claim 12
Dependent Claim
17 words
The process as claimed in claim 1, wherein isothermal treatment stages are combined with non-isothermal treatment stages.
Claim 13
Dependent Claim
18 words
The process as claimed in claim 1, wherein the treatment temperature is controlled solely via the non-inert gas.
Claim 14
Dependent Claim
21 words
The process as claimed in claim 1, wherein the treatment temperature is controlled via the non-inert gas and the treatment agent.
Claim 15
Dependent Claim
22 words
The process as claimed in claim 1, wherein excess treatment agent condensing in the treatment vessel is returned to the jet section.
