Abstract
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.
Claims18
A method of digital printing fabrics, the method comprising:
- supplying a fabric from a first reel by unwinding,
- applying an ink-fixing solution to the supplied fabric,
- compensating a speed of a conveyor belt with a speed of the fabric unwound from the first reel;
- adhering the fabric to the conveyor belt,
- with the fabric adhered to the conveyor belt, digitally printing an ink onto the fabric using a plurality of bars transversally extending above the conveyor belt and provided with ink-jet printing heads, while continuously moving the conveyor belt and electronically controlling the printing heads and synchronizing the printing heads with movement of the conveyor belt, thereby allowing continuous printing,
- drying the fabric, and then
- winding the dried fabric onto a second reel or arranging the dried fabric in sheets;
- wherein the above steps are performed in corresponding stations arranged in sequence while the fabric is continuously passing through the stations.
A method of digital printing fabrics, the method comprising:
- supplying a fabric from a first reel by unwinding,
- applying an ink-fixing solution comprising a pH stabilizer to the fabric by impregnating,
- compensating a speed of a conveyor belt with a speed of the fabric unwound from the first reel;
- adhering the fabric to the conveyor belt,
- while the fabric is adhered to the conveyor belt, digitally printing the adhered fabric using a plurality of bars transversally extending above the conveyor belt and provided with ink-jet printing heads while continuously moving the conveyor belt and electronically controlling the printing heads and synchronizing the printing heads with movement of the conveyor belt, wherein the digitally printing includes digitally printing fibers of the fabric impregnated with the ink fixing solution with reactive ink,
- steaming the printed fabric through a steaming chamber to fix the ink to the fabric,
- drying the steamed fabric, and
- winding the dried fabric onto a second reel or arranging the dried fabric in sheets;
- wherein the above steps are performed in corresponding stations arranged in sequence while the fabric is continuously passing through the stations.
A method of digital printing fabrics comprising the following sequence of steps:
- supplying a fabric from a first reel by unwinding,
- applying an aqueous ink-fixing solution comprising a pH stabilizer to the fabric by impregnating,
- compensating a speed of a conveyor belt with a speed of the fabric unwound from the first reel;
- adhering the fabric to the conveyor belt,
- while the fabric is adhered to the conveyor belt, digitally printing the fabric using a plurality of bars transversally extending above the conveyor belt and provided with ink-jet printing heads while continuously moving the conveyor belt and electronically controlling the printing heads and synchronizing the printing heads with movement of the conveyor belt, wherein the digitally printing includes digitally printing fibers of the fabric impregnated with the ink fixing solution with reactive ink,
- drying the printed fabric, and
- winding the dried fabric onto a second reel or arranging the dried fabric in sheets;
- wherein the above steps are performed in corresponding stations arranged in sequence while the fabric is continuously passing through the stations.
