Problems solved by technology

[0003] As a kind of chemical fiber fabric, polyester fabric needs to be processed by digital heat transfer printing in traditional production. The processing of polyester fabric per meter needs to consume 75g-150g of paper, which consumes a lot of paper during the production process, thus indirectly impact on the environment

Embodiment 1

[0018] Example 1: A digital direct-injection printing process for polyester fabrics, including the following steps: (1) Computer color separation: color separation and toning of the pattern in the computer; (2) Fabric pretreatment: polyester fabric After adding the chemical fiber cloth direct spray pretreatment liquid for color enhancement, it is dried by a dryer at a drying temperature of 180°C; (3) Digital printing: The dispersed ink is sprayed onto the polyester fabric by a digital direct printing machine (4) High-temperature fixation: the polyester fabric after printing is fixed by a steaming machine, the fixation temperature is 190℃, and the time is 30min.

[0019] At the same time, the chemical fiber cloth direct injection pretreatment liquid is a high-performance chemical fiber cloth direct injection special pretreatment liquid purchased from Huanghua City Caizhiyuan Inkjet Technology Co., Ltd. In terms of weight percentage, the disperse ink consists of the following: disp...

Embodiment 2

[0021] The difference between Example 2 and Example 1 is that in step (2) the fabric pretreatment, the drying temperature of the polyester fabric is 185°C; in the step (4) high temperature fixing, the fixing temperature is 205°C. The increase of the fixing temperature increases the diffusion speed of the disperse dye toward the inside of the polyester fiber, which makes the surface of the polyester fabric have better color fastness after fixing.

[0022] At the same time, in terms of weight percentage, the disperse ink consists of the following components: disperse dye 15%; ethylene glycol 12.5%; diethylene glycol 12.5%; surfactant 0.1%; antifungal agent 0.3%; defoamer 0.5%; Ionized water balance. The anti-mold agent is phenol, and the defoaming agent is emulsified silicone oil.

Embodiment 3

[0023] Embodiment 3 differs from embodiment 1 in that in step (2) the fabric pretreatment, the drying temperature of the polyester fabric is 190°C; in step (4) the high-temperature fixing, the fixing temperature is 220°C.

[0024] At the same time, in terms of weight percentage, the disperse ink is composed of the following components: disperse dye 20%; ethylene glycol 15%; diethylene glycol 15%; surfactant 0.1%; antifungal agent 0.1%; defoamer 0.5%; Ionized water balance. The anti-mold agent is phenol, and the defoaming agent is emulsified silicone oil.

Abstract

The invention discloses a digital direct-injection printing processing technology for polyester fabrics, which comprises the following steps: (1) color separation and coloring by computer: color separation and color adjustment of patterns in the computer; (2) pretreatment of fabrics: polyester fabrics Add the chemical fiber cloth direct-injection pretreatment liquid for color enhancement and then dry it through the dryer; (3) Digital printing: use the digital direct-injection printing machine to spray the disperse ink on the polyester fabric to form the required pattern ; (4) High-temperature color fixation: the polyester fabric after printing is fixed by a steamer. The invention has the following advantages and effects: the polyester fabric is directly spray-printed by a digital direct-injection printing machine, and compared with the traditional production of polyester fabric through thermal transfer printing, the consumption of paper is reduced, and the resource is saved.

Description

Technical field [0001] The invention relates to the field of polyester fabric processing, in particular to a digital direct-injection printing process for polyester fabrics. Background technique [0002] Digital printing can be divided into digital thermal transfer printing and digital direct injection. Digital thermal transfer is to transfer the dye to the paper first, and then to the fabric, generally suitable for chemical fiber fabric; digital direct injection is to print directly on the fabric, which needs sizing, spray printing, steaming, and washing. Such steps are generally used on cotton, linen, silk, nylon and other fabrics. [0003] As a kind of chemical fiber fabric, polyester fabric needs to be processed by digital thermal transfer in traditional production. The processing of polyester fabric per meter needs to consume 75g-150g paper, which consumes a lot of paper during the production process, which indirectly The impact on the environment. Summary of the invention ...
