Low-temperature plasma treating process for pigment ink digital injection stamping fabric

Abstract

The invention relates to a plasma body treatment technology of a textile used for colorant ink digital ink jet printing under low temperature, pertaining to fabric printing technical field. The invention is characterized in that the textile is put into a reaction chamber of a processor to be treated by low temperature plasma: the procedure is that: the non-collective air is flowed in, pressure adjusted, then discharged; the colorant ink is jetted and printed to textile treated by low-temperature plasma through a jet-printing machine, thus, the finished products are acquired after the textile being baked. The invention uses non-polymerized gas and low temperature plasma to modify the surface of the textile to improve moisture absorption and hydrophilicity of the modified textile, thus avoiding the problem of bleeding and too light color caused by fabric jet printing directly. The technology is characterized by rapidness, simplicity, water saving, energy conversation, harmlessness and environmental protective, etc.

Description

technical field

[0001] The invention relates to a low-temperature plasma treatment process for fabrics used for pigment ink digital inkjet printing, and belongs to the technical field of textile printing. Background technique

[0002] Digital inkjet printing technology is a new printing technology that integrates information, computer image processing and new materials, and has developed rapidly in recent years. Compared with traditional textile printing, this technology has high printing precision, no need for plate making, flexible batch, fast delivery, no waste and waste of dyes and auxiliaries, and no sewage discharge. It is a clean production technology. In addition, the technology occupies a small area and can realize printing production in offices and homes. According to the type of colorant, digital inkjet printing ink is divided into dye type and pigment type. Inkjet printing of fabrics with pigment-based inks has better light fastness, and does not require post-t...

Embodiment 1

[0020] Embodiment 1: The low-temperature plasma treatment process of fabrics for pigment ink digital inkjet printing of the present invention adopts the following process steps:

[0021] The fabric of the present invention is made of cotton fabric, which is a natural fiber with good water absorption, and the ink-jet printing with pigment ink directly does not cause bleeding, but the color yield is relatively shallow.

[0022] Put the cotton fabric into the reaction chamber of the processor, and then start vacuuming. When the pressure in the reaction chamber is lower than 40Pa, introduce non-polymerizable working gas: argon, and adjust the pressure to 40-100Pa; start discharging, and the discharge power is : 50 ~ 80W; processing time: 1 ~ 2min; cotton fabrics are treated with plasma for inkjet printing, and then baked at 130°C for 3 minutes to obtain finished products.

Embodiment 2

[0023] Embodiment 2: The low-temperature plasma treatment process of fabrics for pigment ink digital inkjet printing of the present invention adopts the following process steps:

[0024] Fabric of the present invention is taken polyester fabric, and polyester fabric is synthetic fiber, and its water absorption is relatively poor, and the fiber surface that forms this fabric is smooth, and water-holding property is also relatively poor, and directly ink-jet printing seepage phenomenon is compared with cotton, real silk and wool with pigment ink. Wait for the fabric to be serious and get a lighter color.

[0025] Put the polyester fabric into the reaction chamber of the processor, and then start vacuuming. When the pressure in the reaction chamber is lower than 30Pa, introduce non-polymerizable working gas: oxygen, and adjust the pressure to 30-50Pa; start discharging, and the discharge power is : 50 ~ 100W; processing time: 5 ~ 10min; after the fabric is treated with plasma, in...

[0027] Embodiment three: The low-temperature plasma treatment process of the fabric for digital inkjet printing of the pigment ink of the present invention adopts the following process steps:

[0028] Fabric of the present invention gets real silk plain weave fabric, adopts following processing parameter to process:

[0029] Put the plain silk fabric into the reaction chamber of the processor, and then start vacuuming. When the pressure in the reaction chamber is lower than 40Pa, introduce non-polymerizable working gas: oxygen, and adjust the pressure to 40-60Pa; start discharging, discharge power For: 60 ~ 90W; processing time: 3 ~ 5min; the fabric is subjected to inkjet printing after plasma treatment, and then baked at 110°C for 5 minutes to obtain the finished product.

[0030] The smoothness of silk fabrics is better, so the images in inkjet printing generally focus on highlighting the sense of hierarchy. After the printing is finished, it can also be rolled and pressed ...
