US 5,172,443 A · Method and apparatus for wet-finishing textile goods

Abstract

In a method for wet-finishing textile goods in the extraction process, the textile goods are made-up in the form of spools or in packages. They are placed in this made-up form in a vessel closable in a pressure-tight manner and the air is then at least substantially removed from the interstices in the textile goods. In the course of the method, the liquor present in the form of an aerosol is made to flow through the textile goods. In order to reduce the water and energy consumption and to also improve the quality of the treatment, the textile goods are first transferred to a state with increased temperature and low residual moisture. Subsequently or or simultaneously, the air is at least substantially removed from the interstices in the textile goods, and after this state has been attained, a gaseous medium under increased pressure which together with the liquor forms an aerosol is made to flow directly through the textile goods.

Dependent claims

Method for wet-finishing textile goods in an exhaustion process, wherein the textile goods have low residual moisture and are made up in the form of spools or in packages, and placed in a vessel, closable in a pressure-tight manner, and

the goods are subjected to a finishing treatment liquor, which is caused to flow through the textile goods in the vessel,
said method comprising the steps of
raising the temperature of the goods above ambient or room temperature;
substantially removing air from interstices of the textile goods until the goods have achieved essentially air-free state;
and
applying an aerosol which comprises a gaseous medium and the treatment liquor dispersed therein at a pressure in excess of the pressure prevailing in the vessel to one side of the textile goods, the gaseous medium developing a higher pressure on one side of the textile goods than on the other side thereof, so that the gaseous medium of the aerosol will flow directly through the goods for a predetermined period of time.

a vessel (3) closable in pressure-tight manner;
support means (4) for supporting the goods (8) located within the vessel forming a material holder;
a pipe line system (9, 11, 12, 13);
gas pressure generating means (18),
said pipe line system including
a first connecting line (12) connecting the interior of the vessel to said gas pressure generating means (18) at one terminal side thereof;
and
a second connecting line (9) connected to the interior of said vessel and coupled to the support means (4) and connected to said gas pressure generating means (18) at another terminal side thereof;
temperature controlling means (15, 16) coupled to be pipe line system to control the temperature of the gas therein;
humidity or moisture controlling means (17) coupled to the pipe line system to control the moisture of the gas flowing in the pipe line system;
a pressurized finishing liquid supply means (45-48);
an atomizing device (38, 73);
and
