Process flow and key points analysis of water-based ink printing non-woven fabric
Date: Oct 18 2023 From: Star Color
With the continuous improvement of environmental awareness, the technology of water-based ink printing non-woven fabrics has been widely used in various fields.Water-based ink printing non-woven fabric has the advantages of environmental protection, beauty and high production efficiency, and has become the development trend of the packaging and printing industry.
Process flow of water-based ink printing non-woven fabric
The process flow of water-based ink printing non-woven fabrics includes the following steps:
1.Preparation before printing
Before printing, it is necessary to prepare non-woven fabrics,
non-woven water-based inks, printing equipment, etc.At the same time, the non-woven fabric is inspected, cleaned and dried to ensure the printing effect and quality.The type and quality of non-woven fabrics have a great impact on the printing effect, so it is necessary to strictly control the quality of non-woven fabrics.
2.printing
According to the need to print the pattern and color, the water-based ink is blended.Then, printing equipment is used to print the ink onto the non-woven fabric.In the printing process, it is necessary to control the viscosity of the ink, printing pressure, printing temperature and other factors to ensure the stability and beauty of the printing effect.At the same time, it is necessary to pay attention to prevent problems such as blockage and wire drawing in the printing process.
3.Dry
The water-based ink needs to be properly dried after printing, so that the ink is firmly attached to the non-woven fabric.The drying method can be natural drying or using drying equipment for drying.In the case of natural drying, it is necessary to control the ambient temperature and humidity to avoid problems such as uneven drying and color migration.In the case of drying equipment, it is necessary to control the drying temperature and time to avoid problems such as ink damage or ink residue caused by excessive drying.
4.Reprocessing
Finally, the printed non-woven fabric needs to be post-processed, including inspection, packaging，etc.In the inspection process, it is necessary to strictly control the printing effect and quality to ensure the pass rate of the product.At the same time, it is necessary to rework or scrap unqualified products to avoid affecting the overall quality and production efficiency.
Analysis of the main points of water-based ink printing non-woven fabric
The technical points of water-based ink printing non-woven fabrics include the following aspects:
1.Selection of ink
The selection of water-based ink is one of the keys to printing non-woven fabrics with water-based ink.It is necessary to choose water-based inks with suitable viscosity, strong adhesion, bright color, weather resistance and water resistance, non-toxic and environmental protection.At the same time, it is necessary to consider the applicability of the ink brand and model to ensure the printing effect and quality.It should be noted that the performance and range of use of water-based inks vary among different brands and models. Therefore, it is necessary to have a thorough understanding of the ink and conduct sample testing to ensure that the selected ink can meet production needs.
2.Selection of printing equipment
The selection of printing equipment has a great impact on the efficiency and effect of water-based ink printing nonwovens.It is necessary to select suitable printing equipment and printing methods according to the actual production needs and the characteristics of printing materials.For example, it is necessary to select printing equipment with high precision, good stability and strong adjustment to ensure the stability and beauty of the printing effect.At the same time, it is necessary to pay attention to the maintenance and maintenance of printing equipment to ensure the normal operation and service life of the equipment.
3.Selection and treatment of non-woven fabrics
The selection and treatment of non-woven fabrics also have a great impact on the efficiency and effect of water-based ink printing non-woven fabrics.It is necessary to choose the varieties and quality of non-woven fabrics that meet the production needs and design requirements, and to clean, dry and other pretreatment of non-woven fabrics.At the same time, it is necessary to conduct reasonable typesetting and positioning of non-woven fabrics to avoid problems such as printing errors or deviations.It should be noted that the texture and fiber length of non-woven fabrics also have an impact on the printing effect, so it is necessary to conduct adequate research and analysis of non-woven fabrics to ensure that the selection and treatment of non-woven fabrics can meet the production needs.
4.Control of the production environment
The production environment of water-based ink printing nonwovens has a great impact on the printing effect and product quality.It is necessary to control the environmental temperature, humidity, cleanliness and other parameters to avoid problems such as reduced ink adhesion, uneven drying, and dust adhesion.At the same time, it is necessary to pay attention to the control of the cleanliness and hygiene of the production environment to avoid problems such as bacterial cross infection affecting product quality.
In this paper, the technical process and key points of water-based ink printing nonwovens are analyzed and discussed in detail.Water-based ink printing non-woven fabric has the advantages of environmental protection, beautiful appearance and high production efficiency, so it has been widely used in various field.In order to achieve the efficient and high-quality production of water-based ink printing nonwovens, it is necessary to fully grasp the process flow and key points of water-based ink printing nonwovens, and continue to explore and innovate more advanced production technology and equipment.This will help to improve the product quality and production efficiency of water-based ink printing nonwovens, and make greater contributions to promoting the sustainable development of the packaging and printing industry.
