A method of digital printing and finishing for fabrics is provided. The method includes a step of unwinding a fabric from a first reel. A step of compensating the speeds and of spreading the fabric for its positioning on a conveyor belt provided with supporting elements on which a digital printing step occurs is provided. A step of drying the fabric is provided. A step of winding the fabric onto a second reel is provided. These steps are being executed at corresponding stations arranged in sequence with respect to each other and the fabric passing through them continuously, transversely to the conveyor belt, there being a plurality of bars provided with printing heads which are controlled electronically and synchronized with the movement of the conveyor belt.

An encapsulated dye, may include a dye, such as a vat dye, and an encapsulating agent, such as cyclodextrin. A dye formulation is provided for dyeing a fiber, a yarn including a fiber, and/or a fabric including a fiber. The fiber may be a synthetic fiber. A method of preparing an encapsulated dye and/or a dye formulation, and to a method of dyeing are also described. A fiber, a yarn, and/or a fabric including an encapsulated dye, a fiber, a yarn, and/or a fabric dyed with an encapsulated dye, an installation for dyeing, and to uses of a cyclodextrin, an encapsulated dye, and an installation are provided.

A roll-to-roll process and apparatus is disclosed for treatment of a membrane substrate. The apparatus and process processes the membrane substrate in a forward direction using one or more treatment solutions, and then processes the membrane substrate in a reverse direction using other treatment solutions. The treatment solutions used in the forward and reverse directions are preferably chosen so that the treatment sequence is the same in both directions. In this manner, the membrane substrate can accumulate reaction time by repeated processing in forward and reverse directions. t,?

Systems and methods, as well as a machine, which can be used to improve constancy of fabric exposure to chemicals in a liquid bath and particular in the process of metallization. These systems and methods can be used to provide for more effective batch processing of fabric but can also be linked together to provide for what is effectively a continuous process as well.

The present invention includes (i) a liquid storing tank in which an impregnating liquid is stored, (ii) a hollow tube provided in the liquid storing tank, (iii) a vacuum pump which produces a vacuum in one end of the hollow tube, and (iv) a transport mechanism which transports a porous material in the impregnating liquid drawn into the hollow tube. A degree of vacuum in the vacuum is maintained in a given range.

Apparatus and method for washing an elongate textile article of extended indeterminate length utilizes a containment structure defining a channel extending upwardly from a lower end to an upper end thereof, with a plurality of undulations spaced-apart from one another within the channel between the lower and upper ends thereof, each undulation extending transversely across the channel. A portion of the lengthwise extent of the traveling textile article is advanced transiently within the channel upwardly from the lower end to the upward end and across the undulations, while a substantially continuous supply of cleansing liquid enters the channel at the upper end to flow downwardly against the upwardly traveling portion of the textile article for cleansing thereof.
