The secret of washing process: How to ensure the environmental protection and safety of digital printed single-sided knitted fabrics?

In the washing process of digital printed single-sided knitted fabrics, water quality is the primary consideration. Impurities, hardness, pH value and microbial content in water will pose a potential threat to the cleanliness and safety of fabrics. High-hardness water contains more calcium and magnesium ions, which are easy to combine with the ingredients in detergents to form precipitates attached to the surface of fabrics, affecting the washing effect and even causing the fabric to become hard and dull. The presence of microorganisms may cause fabric mildew, damage the quality of fabrics, and even pose a threat to human health.

Therefore, using pure water or softened water for washing is the basis for ensuring the environmental protection and safety of fabrics. Regularly testing water quality to ensure that the pH value is maintained within an appropriate range is also an important measure to ensure the washing effect.

The choice of water temperature is also an important part of the washing process that cannot be ignored. Appropriate water temperature can accelerate the dissolution and diffusion of detergents, improve washing efficiency, and at the same time help relax fabric fibers, making deep dirt easier to remove. However, too high water temperature may cause the fabric to shrink, deform, or even destroy the dye structure on the fabric, causing color fading or color difference.

For digital printed single-sided knitted fabrics, the choice of water temperature is particularly critical due to its special fiber structure and printing process. Generally speaking, the optimal washing temperature should be determined comprehensively based on the material of the fabric, the nature of the printing dye, and the recommended temperature of the detergent. Through precise temperature control, it can not only effectively remove dirt and unfixed dyes on the fabric, but also protect the original color and texture of the fabric.

The type and concentration of detergent directly determine the quality of the washing effect. In the washing process of digital printed single-sided knitted fabrics, it is very important to choose a suitable detergent. The ideal detergent should have excellent decontamination ability and good compatibility with fabric fibers and printing dyes to avoid fabric damage or color fading.

In addition, the concentration of the detergent must also be strictly controlled. If the concentration is too low, the dirt and unfixed dyes on the fabric may not be effectively removed; if the concentration is too high, the fabric may be over-washed, destroying the fiber structure, causing the fabric to feel hard and the color to fade. According to the characteristics of the fabric and the washing requirements, the reasonable adjustment of the concentration of detergent is the key to achieve a balance between washing effect and fabric protection.

In order to ensure the environmental protection and safety of digital printed single-sided knitted fabrics, strict control of the washing process is essential. This includes water quality monitoring, water temperature adjustment, detergent selection and concentration adjustment. In the actual production process, enterprises should use advanced testing equipment to monitor the water quality regularly to ensure that the water quality meets the production requirements. According to the characteristics of the fabric and the washing requirements, detailed washing process parameters are formulated, including water temperature, washing time, detergent type and concentration, etc., and strict process control is used to ensure that each link achieves the best effect.

Enterprises should also strengthen employee training, improve employees' awareness of the importance of washing process, ensure that every employee can master the operation skills of washing process, strictly abide by the production process regulations, so as to reduce the impact of human factors on product quality.

With the increasing awareness of consumers on environmental protection and health, the environmental protection and safety of digital printed single-sided knitted fabrics have become the focus of market attention. Enterprises should not only pay attention to the beauty and function of products, but also pay attention to the environmental protection and safety performance of products to meet the needs of consumers.

In the water washing process, adopting environmentally friendly detergents, reducing water consumption, and improving wastewater treatment efficiency have become important ways for enterprises to achieve green production and fulfill their social responsibilities. By continuously optimizing the water washing process, enterprises can not only improve the environmental protection and safety of products, but also reduce production costs, improve market competitiveness, and achieve a win-win situation of economic and social benefits.
