Yisheng digital textile printing machine is a direct jet pattern printing process on fabrics using digital technology. It has the advantages of high efficiency, low cost, and environmental protection, and is widely used in textile production. Some fabrics require a series of pre-treatment before digital printing. The purpose of pre-treatment is to remove the natural impurities contained in the fiber as well as the slurry and oil stains applied during textile processing, so that the fiber can give full play to its excellent qualities and make the fabric white. , soft and breathable, meeting the requirements. We also provide qualified semi-finished products for dyeing, printing and finishing. The following is the pre-processing before digital printing of textiles:
1. Inspection and cleaning
Before using a Boyin digital printing machine, the textile must be thoroughly inspected to ensure that there are no defects such as stains, damage, or uneven texture. In addition, textiles need to be cleaned to remove oil, dust and other impurities that may affect the printing effect.
2.Pre-shrinking
In order to prevent dimensional changes caused by shrinkage after textile printing, pre-shrinking is required. Most shrinkage can be removed early by soaking the textile in hot water or steaming it.
3.Desizing treatment
Desizing refers to the removal of size from textiles and is often used in the weaving process to enhance the strength and stability of the yarn. Desizing helps ensure better penetration of ink into the fibers, improving the quality and durability of your prints.
4. Bleaching treatment
For prints that require a particularly white background, the textile may need to be bleached. Bleaching removes natural pigments from textiles, providing a uniform white background for digital printing.
5.Softening treatment
Softening improves the feel and softness of textiles, which is critical to increasing the comfort of the final product. Softeners can be chemical agents or natural materials, such as lanolin or vegetable oils.
6. Use preprocessing
Pretreatment fluids are often used to improve ink adhesion to textiles. It can be water-based or solvent-based, depending on the type of ink used and the material of the textile. Boyin's digital printing pre-treatment agent can improve the hand feel of textiles, improve color brightness and pattern clarity.
7. Drying treatment
Textiles may undergo multiple wetting and drying processes during the pretreatment step. It is important to ensure that the textile is completely dry before printing to avoid uneven ink penetration or bright colors.
Through these pre-processing steps, the quality and efficiency of digital printing can be greatly improved while reducing waste and errors in production. Yisheng digital printing pre-treatment agent can improve the clarity of textile patterns, bright colors, and softness, and the product is environmentally friendly.
