A rinsing station for removing residual materials from a fabric being dyed or bleached. The rinsing station includes a first pair of rinse spray nozzles. One of the first pair directed to spray a rinse fluid downwardly onto incoming dyed fabric. The other of the first pair directed to spray the rinse fluid upwardly onto the incoming dyed fabric. The rinsing station also includes a pair of nip rollers downstream for the first pair of rinse spray nozzles for extracting the rinse fluid.

A dye fixing section in a foam indigo dyeing machine for dyeing traveling sheets of textile yarn. The dye fixing section receives traveling sheets of yarn to which indigo dye in leuco form has been applied and penetrated partially through the yarn. Oxygen is applied to the substrate to set the dye at the level of penetration achieved as it enters the dye fixing section, to produce yarns in the sheet with outer dyed rings and undyed cores.

The present invention is at least one coating machine (1) having at least one impregnation unit (2) for realizing dyeing during wrapping of the yarn (26) from at least one first bobbin (25) onto at least one second bobbin (41), at least one drying unit (3) for providing drying of the yarn (26) dyed essentially in the vicinity of said impregnation unit (2), at least one first roller (355) and at least one second roller (359) positioned mutually for providing moving of the yarn (26) at a predetermined line in said drying unit (3), at least one wrapping unit (4) for providing wrapping of the yarn (26), dyed in the vicinity of the drying unit (3), onto said second bobbin (41). The improvement of the present invention is that said second roller (359) is configured to displace between an operation position (I) defined at one side of said first roller (355) and a yarn changing position (II) defined at the other side of said first roller (355).

There is provided an anhydrous dyeing system for yarn, including: a transfer printer which repeatedly sprays dye ink on a surface of a transfer sheet a plurality of times to laminate and apply ink layers; a dyeing jig which is in a drum form having a plurality of microholes formed in an outer circumferential surface thereof to penetrate inside and outside; a process chamber into which the dyeing jig is put; a heating member for heating the yarn wound on the dyeing jig, by supplying heat to the inside of the process chamber; and a vacuum-generating member which is in communication with an internal space of the dyeing jig and vacuum-evacuates the air in the internal space of the dyeing jig to thereby form a vacuum pressure inside the dyeing jig.

Processes and apparatus are disclosed which substantially eliminate the formation of oxidized indigo dye before and during dye application onto a natural fiber yarn or fabric while allowing the leuco-indigo dye molecule to diffuse fully into the natural fibers of the yarn where it can fix to the fibers prior to oxidation (i.e., exposure of the leuco-dyed yarns to oxygen). Indigo dyed textile products (e.g., dyed cotton yarns that may be twill woven to form a denim fabric) exhibit exceptionally high colorfastness as determined by the AATCC Crock Test.

A recording apparatus includes a printing portion and a first conveying portion. The printing portion ejects liquid to print a medium having elasticity. The first conveying portion is disposed upstream of the printing portion in a conveying direction along which the medium is conveyed to the printing portion. The first conveying portion includes at least two conveying bodies disposed in the conveying direction and around which the medium is alternately wound. The conveying bodies each include a shaft extending in a width direction orthogonal to the conveying direction and a plurality of rollers rotatably supported by the shaft. The plurality of rollers are supported to be inclined outward with respect to the conveying direction from upstream to downstream in the conveying direction.
