Boyin digital textile printing machine is a kind of direct spray pattern printing process using digital technology on fabrics, it has the advantages of high efficiency, low cost, environmental protection and so on, and is widely used in textile production. Some fabrics need to carry out a series of pre-treatment before digital printing, the purpose of pre-treatment is to remove the natural impurities contained in the fiber and the slurry and oil stains applied in the textile processing, so that the fiber can give full play to its excellent quality, and make the fabric with white, soft and good permeability to meet the requirements. And provide qualified semi-finished products for dyeing, printing and finishing. The following is the pre-treatment of textiles before digital printing:
- 1.Inspection and cleaning
- Before using a Boyin digital printing machine, a thorough inspection of the textile must be carried out to ensure that there are no imperfections such as stains, breakage 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-shrinkage treatment
- Pre-shrinkage treatment is necessary to prevent dimensional changes caused by shrinkage of textiles after printing. By soaking textiles in hot water or steam treatment, most of the shrinkage can be removed in advance.
- 3.Desizing treatment
- Desizing refers to the removal of sizing from textiles, which is often used during weaving to enhance the strength and stability of yarns. Desizing helps to ensure that the ink can better penetrate into the fibers, thus improving the quality and durability of the print.
- 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 an even white background for digital printing.
- Softening treatments can improve the feel and softness of textiles, which is essential to improve the comfort of the final product. Softeners can be chemical agents or natural materials such as lanolin or vegetable oil.
- Pre-treatment fluids, are commonly used to improve the adhesion of ink to textiles. It can be water-based or solvent-based, depending on the type of ink used and the material of the textile. Boyin digital printing pre-treatment agent can improve the feel of textiles, improve color brightness, pattern clarity.
- 7.Drying treatment
- In the pre-treatment step, the textile may need to go through several wetting and drying processes. It is very important to ensure that textiles are completely dry before printing to avoid uneven ink penetration or bright colors.
Through these pre-treatment steps, the quality and efficiency of digital printing can be greatly improved, while reducing waste and errors in production. Boyin digital printing pre-treatment agent can improve the textile pattern clarity, color brightness, feel softness, environmental protection products，For more information, please call Dee dee: 18368802602 or Email: sales01@boyinshuma.com
