A system and a method for treating a textile material with ozone gas. The system includes: an ozone gas supply system, a hollow chamber fillable with ozone provided by said gas supply system, a textile-feeding port connected to said chamber and comprising a first liquid fillable tank, a textile-discharging port connected to said chamber and comprising a second liquid fillable tank, guide rollers, driving rollers, at least one tension compensator located inside the hollow chamber. The system is adapted for implementing the method, the latter including: using the system and providing liquid to said first and second tanks, providing ozone gas to said hollow chamber, driving the textile material to pass tensed through the system while controlling its tension using the tension compensators. The use of the tension compensators prevents the formation of ozone induced defects on the textile material.

A system can include a heatset steam tunnel extending along a longitudinal axis. The heatset steam tunnel can have an inlet/outlet structure, the inlet/outlet structure extending along a horizontal axis that is perpendicular to the longitudinal axis and a vertical axis that is perpendicular to the horizontal axis and the longitudinal axis. An operator space positioned adjacent the inlet/outlet structure of the heatset steam tunnel. A guard can at least partially covering the inlet/outlet structure. The guard can comprise a transparent window material. The guard can be configured to direct steam from the inlet/outlet structure of the heatset steam tunnel away from the operator space while permitting viewing into the inlet/outlet structure from the operator space.

A method and an apparatus for desizing and/or shrinking a textile fabric, the textile fabric having a length and a width, the method including moving, lengthwise, the fabric, and wetting the fabric within a first pool of liquid, the first pool of liquid including water; passing the fabric through a chamber, and in the chamber contacting the fabric with at least one heatable roller heated at a treatment temperature; soaking the fabric with a main pool of liquid, the main pool of liquid including water; and treating the fabric with ozone. The apparatus includes a first module for wetting the fabric, a second module with a heatable roller for heating the fabric, a third module for soaking the fabric, and fourth module for treating the fabric with ozone. The second module may optionally be integrated with the first module.

A waterless dyeing device for cone yarn, a waterless dyeing method and a produce are provided; wherein the device comprising: a dye autoclave (1); a dyeing autoclave (2); a recycle autoclave (6); a dyeing circulation system in which the dye autoclave (1), the dyeing autoclave (2) and the recycle autoclave (6) are in fluid communication with; wherein further comprises: a cone yarn inlet formed on the top of the dyeing autoclave (2), which is provided with a sealing cap (7); a cone yarn center shaft (10) vertically disposed at the center inside the dyeing autoclave, which is a perforated outlet tube with fluid discharge holes opened on the side wall; an intake pipe (13) disposed on the bottom of the dying autoclave (2) which is in communication with the cone yarn center shaft (10); a dyeing autoclave outlet (9) disposed on the dying autoclave (2); and a CO2 container (4), a pressure pump, a circulation pump (3) and conduits which are included in the dyeing circulation system. The dyes are disposed in the dye autoclave (1) and the cone yarns are disposed inside the dyeing autoclave (2), CO2 is introduced into the dye autoclave (1) to dissolve the dyes gradually, and the CO2 carrying the dyes to the dyeing autoclave (2) to dye and diffuse. The present invention has the advantages of being high in production efficiency, even in dyeing effect and high in safety, and is suitable for waterless dyeing of polyester cone yarns.

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.

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.
