Embodiment 1

[0022] The normal-pressure low-temperature plasma pretreatment process of fabrics for digital inkjet printing of the present invention adopts the following process steps:

[0023] Cotton fabric is selected as the fabric. Cotton fabric is a natural fiber with good water absorption. Directly inkjet printing with pigment ink will not cause bleeding, but the color yield is relatively light. Put the cotton fabric into the reaction chamber of the processor for pulsed atmospheric pressure air low-temperature plasma treatment: then start to discharge, the discharge power density is: 0.12W / cm 2 , the processing time is: 30s, and the distance between the plates is: 5mm; the cotton fabric after low-temperature plasma treatment is ink-jet printed on a digital ink-jet printing machine with water-based pigment ink; the temperature of the cotton fabric after ink-jet printing is: Baking at 130°C for 3 minutes is the finished product.

[0024] The inkjet printing results are shown in Table 1....

Embodiment 2

[0039] The normal-pressure low-temperature plasma pretreatment process of fabrics for digital inkjet printing of the present invention adopts the following process steps:

[0040] The fabric is polyester fabric. Polyester fabric is a synthetic fiber, which has poor water absorption, and the fiber surface of the fabric is smooth, and the water holding capacity is also poor. The inkjet printing directly with pigment ink has a more infiltration phenomenon than cotton, silk and wool. Serious, and the color is lighter, the following processing parameters are used for processing: discharge power density 0.24W / cm 2 , the processing time is 3min, and the distance between the plates is 2mm. Process flow: After the fabric is treated with plasma, it is printed by inkjet, and then it is heat-set at 180°C for 30 seconds to get the finished product.

[0041] Due to the good reflective properties of polyester fabrics, patterns generally do not require special treatment. After digital inkje...

Embodiment 3

[0045] The normal-pressure low-temperature plasma pretreatment process of fabrics for digital inkjet printing of the present invention adopts the following process steps:

[0046] Wool fabric is selected as the fabric. Wool fabric has strong hydrophobicity. Direct inkjet printing will also produce similar bleeding phenomenon, and the color will be lighter. The following processing parameters can be used for processing: discharge power density 0.40W / cm 2 , the processing time is 4min, and the distance between the plates is 3mm. The wool fabric is treated with the above treatment parameters, and the process flow is as follows: After the fabric is treated with the above treatment process parameters, inkjet printing is carried out, and after the printing is completed, it is heat-set at 150°C for 3 minutes to finally obtain a finished product. The inkjet printing results are shown in Table 3.

Abstract

The invention relates to fabric plasma surface modification processing technology used in dye ink digital inking printing. The fabric is processed inking printing by dye ink in the digital inking printing machine after processing by impulse normal pressure air low temperature plasma, then baking to form the finished product. Compared with the traditional preprocessing technology, the invention has the advantages of fast, convenient, saving water and energy, low cost, no social effects of pollution, suiting for industrialization continuous production etc.

Description

technical field [0001] The invention relates to a normal-pressure low-temperature plasma pretreatment process for digital ink-jet printing fabrics, and belongs to the technical field of textile printing. Background technique [0002] Digital inkjet printing technology is a new printing technology that integrates high technologies such as information, computer image processing and new materials. In recent years, it has developed rapidly and has been applied in practice. Compared with traditional textile printing, it has high printing fineness; no need for plate making, flexible batch size, which can realize single-piece production or mass production; fast delivery speed; no waste and waste of dyes and auxiliaries, no sewage Emission, is a real clean production technology; small footprint, can be printed in offices and homes and other advantages. [0003] Digital inkjet printing ink can be divided into two types: dye type and pigment type. Compared with dye inks, inkjet pri...
