AI Technical Summary
Existing dyeing methods for nylon-cotton blended fabrics suffer from problems such as long dyeing processes, high time consumption, high energy consumption, serious pollution, severe dye staining, and poor economic benefits, making it difficult to simultaneously meet the dyeing needs of nylon and cotton fibers.
By utilizing the synergistic catalytic effect of bio-enzymes and metal salts, and through ultrasonic treatment, metal ion complexation modification, and one-bath dyeing, efficient dyeing of cotton-nylon blended fabrics is achieved. The process includes pretreatment, metal ion complexation modification, and one-bath dyeing steps, using acidic dyes at room temperature to high temperature.
It significantly shortens the dyeing process, improves production efficiency, reduces energy consumption and environmental pollution, and produces products with bright colors, soft hand feel, and excellent performance. It also simplifies the operation process and improves dyeing quality and economic benefits.
