| titleOfInvention | An environmentally friendly dyeing method for speaker paper cones |
| abstract | The invention discloses an environment-friendly dyeing method for speaker paper cones. (1) In-pulp dyeing method is adopted for the first light dyeing: pulp, carboxymethyl cellulose, direct dyes, sizing agent and water are mixed and beaten, and simultaneously Add flake alkali or soda ash to adjust the pH to alkaline, the dyeing time is 25-45 minutes, and the temperature is 35-45°C; (2) After the first light dyeing, paper is made to obtain a paper basin wet embryo, and the first light dyeing is collected. The dyeing waste liquid is filtered, and the filtered dyeing waste liquid is recycled for the next light dyeing; (3) The paper cone carcass is obtained after drying the wet embryo body of the paper cone, and the surface of the paper cone carcass is complemented and fixed. , and the finished product is obtained after the final baking treatment. The invention can recycle the colored wastewater for many times, can reduce the treatment and discharge amount of the colored wastewater, improve the utilization rate of dyes, and has important significance for reducing the dyeing cost and environmental protection problems of the paper cone factory. |
