A conveyor driven fabric dyeing machine includes a dyeing tube for improving fabric dyeing effect. The dyeing tube is arranged rearward of or below a nozzle and has an entrance opening and an exit opening and an intermediate section located between and set lower than the entrance opening and the exit opening so as to form height differences at front and rear end parts of the dyeing tube that allows dye liquid to fill up and remain in the dyeing tube. During a course of fabric moving through the dyeing tube, the fabric is allowed to stay and soak in the dye liquid within the dyeing tube to provide an extended period of time of interaction between the fabric and the dye liquid for penetration so as to enhance the result of dyeing.

The invention discloses a mobile dyeing cup for supercritical fluid waterless dyeing and finishing. The dyeing cup achieves separate or simultaneous filling of the medium into multiple dyeing units, and simultaneous heating of the dyeing units for proofing processing. A medium outlet is provided at the lowest position of the bottom of the cup, and the inner surface of the dyeing cup is coated with polytetrafluoroethylene, to effectively reduce residual dye chemicals in the cup and improve the cleaning efficiency. The perforated baffle at the bottom of the cup effectively prevents a textile product from blocking the medium outlet during medium filling and outputting, so that the processing medium and residual dye chemicals can be smoothly discharged. Accordingly, defects of an existing fixed proofing device such as low utilization efficiency, complex cleaning and incapability of meeting the proofing requirements of commercial production are overcome.

A stretching apparatus of fibre tows in a pressurized steam environment includes an elongated stretching chamber having a generally rectangular section of a low height, within which the tows are treated with saturated or overheated steam at high temperature and pressure and simultaneously undergo a mechanical stretching operation. The stretching chamber has a width sufficient to house multiple tows mutually flanked in a running plane and is formed within a stretching chest made of aluminum. The stretching chest is housed in a supporting structure, having a higher structural rigidity than the stretching chest, which includes a plurality of contact elements apt to determine a predefined position of the stretching chest with respect to a direction perpendicular to the tow running plane and to allow a limited mobility of the stretching chest in the other two mutually perpendicular directions which lie in the plane, length and width respectively.

Methods and kits for treating a fibrous substrate prior to forming an image thereon are provided. The method can include positioning a treatment sheet adjacent to the fibrous substrate, transferring a salt (e.g., calcium chloride, magnesium chloride, or a mixture thereof) from the treatment sheet to the fibrous substrate using a wetting solution (e.g., an aqueous solution, such as water) to carry the salt from the treatment sheet into the fibrous substrate, and drying the fibrous substrate such that the salt remains in the substrate. For example, the transfer of the salt from the treatment sheet into the fibrous substrate can be accomplished via pressing the backside of the treatment sheet such that the wetting solution flows from the treatment sheet into the fibrous substrate while carrying the salt.

Embodiments relate generally to methods and systems for bleaching textiles using ozone gas that incorporates a color removal step. In one example, there is provided a hybrid machine that incorporates certain features of a washer, but that also includes an integrated blower for gas distribution inside the machine. There is also provided an ozone dosing control system that allows for maintenance of a constant concentration of ozone in the machine. In one embodiment, the ozone output measured in grams/hour at this constant concentration in conjunction with the weight of product measured being treated may be referred to as the bleaching factor. There is further provided a wastewater dye removal step, in which ozone is used to clean the water and remove dyes and other colors that may be deposited via denim or other garments.
