Problems solved by technology

The pretreatment and post-finishing of printed fabrics prolong the process of fabric treatment, and the process of impregnation or padding of the entire fabric also affects the hand feeling of the fabric
In the printing process, since the dye or paint is selectively attached to the specific position of the fabric, that is, the color is discontinuous on the surface of the fabric, the treatment method of dipping or padding the pretreatment liquid or the finishing liquid will make the blank area of ​​the printing still fix the pretreatment Treatment liquid or finishing liquid not only wastes the sol but also reduces the hand feeling of the fabric due to the continuous distribution of pre-treatment liquid or finishing liquid

Embodiment 1

[0018] The three nozzle groups of the waterless three-jet one-in-one process inkjet printing system are respectively filled with starch slurry, paint ink, and a mixture of adhesive and anti-ultraviolet agent. Among them, the nozzle group program where the starch pretreatment liquid and the mixture of adhesive and anti-ultraviolet agent are located executes the combined color single-color ink output mode of the pattern color, and the spray volume is 100% of the system default spray volume, and the spray printing width is the system default 120% of the width. Paint ink implements CMYK four-color output mode to print on cotton fabrics, and the inkjet volume is 100% of the system’s default liquid spray volume. The printed cotton fabric was baked at 160°C for 3 minutes to obtain a printed cotton fabric sample.

Embodiment 2

[0020] Sodium alginate paste, disperse dye ink and antistatic agent solution were respectively filled in the three nozzle groups of the waterless three-jet integrated process inkjet printing system. Among them, the program of the nozzle group where the sodium alginate pretreatment solution and the antistatic agent solution are located executes the combined color monochrome ink output mode of the pattern color, the spray volume is 100% of the system default spray volume, and the printing width is 100% of the system default width. %, disperse dye ink implements CMYK four-color output mode to print on polyester fabric, and the inkjet volume is 120% of the system's default liquid volume. The printed polyester fabric was steamed at 200°C for 2 minutes to obtain a printed polyester fabric sample.

Abstract

The present invention discloses a method for carrying out digitalized spray printing through a water-free type three-spraying integrated process. According to the method, three groups of sprayers are controlled to carry out superimposed spray printing of different spray printing components on a fabric so as to achieve the three-spraying integrated spray printing of the fabric. The technical scheme of the present invention are that: a pre-treatment liquid, an ink, a post-finishing liquid and other spray printing components are respectively filled in the three groups of the sprayers, and the three spray printing components are subjected to superimposed spray printing on the fabric according to a certain sequence. According to the present invention, each spray printing component is subjected to spray printing according to the requirement, only the pattern area is treated so as to effectively reduce the waste of the pre-treatment liquid and the post-finishing liquid, the positions excluding the pattern area are not affected by the pre-treatment liquid and the post-finishing liquid so as to reduce the influence of the multiply treatments on hand feeling, gas permeability and other performances of the fabric, and the three-spraying integrated spray printing integrates the three tedious processes such as the pre-treatment, the inkjet printing and the post-finishing into the one-step spray printing process so as to eliminate the multiply treatment processes adopting water as the medium, effectively shorten the fabric treatment process, and reduce the wastewater discharge.

Description

technical field [0001] The invention relates to a spray printing method, in particular to a digital spray printing method using an anhydrous three-spray integrated process. Background technique [0002] Inkjet printing technology realizes the small batch, multi-variety, flexible and fast processing methods of textiles, and has been widely promoted and applied. In order to improve the brilliance of inkjet printing colors, the fineness of lines or the fastness performance, textiles need to be pretreated before inkjet printing to ensure that the textiles have a good wool effect, and subsequent finishing is also required to improve the fabric fastness or other fabric properties. The pretreatment and post-finishing of printed fabrics prolong the process of fabric treatment, and the process of impregnation or padding of the entire fabric also affects the hand feeling of the fabric. In the printing process, since the dye or paint is selectively attached to the specific position o...
