Description

Package dyeing method and cheese dyeing production equipment

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of textile printing and, in particular, to a cheese dyeing method and a cheese yarn dyeing production apparatus. BACKGROUND OF THE INVENTION China is a big textile country. The printing and dyeing process is a key link in the textile industry chain, and it is also the most direct process for product value-added. At present, China's textile printing and dyeing industry has problems such as high energy consumption, serious pollution, low production efficiency, labor shortage, poor dyeing quality and low automation level.

1 unit product has high energy consumption. China's textile printing and dyeing industry consumes 5.64 tons of standard coal per printing and dyeing 10,000 meters, exceeding the national energy consumption standard by 1.8 times. Compared with foreign countries, China's water consumption per unit of product is 2 to 3 times that of developed countries, and energy consumption is 3 to 5 times that of foreign countries. The reuse rate of water is only 7%, which is 1/3 of the advanced level in foreign countries.

2 The sewage discharge is large and the pollution is serious. According to incomplete statistics, China's textile industry consumes more than 10 billion tons of water per year. It ranks second in all industries in terms of fresh water intake, and its wastewater discharge ranks sixth in the country. Among them, printing and dyeing wastewater accounts for national textile wastewater. 80% of total emissions, high in chemical content in sewage, difficult to remove, chemical oxygen demand COD of printing and dyeing wastewater is 400~4000mg/L, 8 times higher than Class III water quality; BOD is 100-1000 mg /L, 3 times higher than Class III water.

3 production efficiency is low. The foreign sample rate has reached more than 90%, and there are very few enterprises in China that can reach more than 80% of the sample rate, which leads to repeated dyeing, which restricts dyeing efficiency and reduces production efficiency.

4 poor dyeing quality. There are many factors affecting the quality of dyeing, including equipment factors, human factors, process factors, raw material factors, etc. Some factors affect all processes, and many factors directly affect product quality.

5 equipment automation is not high. China's textile industry is relatively backward compared with other industries. At present, in the technical equipment of the textile industry, only 50% of the technical level in the 1990s is reached, and the gap between the equipment technology level in the dyeing and finishing industry is greater. Some equipments are in an extended service state, the automation level of equipment is low, and online testing is lacking. Feedback means. 6 industry labor shortage. As a labor-intensive industry and a labor-intensive industry, the printing and dyeing industry is more difficult to recruit. In the case of full production orders, many companies are facing a "labor shortage" in the face of increasing orders. At present, some semi-automatic cheese dyeing production lines suitable for horizontal dyeing cylinders have been developed in the industry, and some production processes still require manual participation. Compared with the vertical cheese dyeing, the horizontal dyeing machine has a larger relative dyeing bath ratio, and the dyeing water consumption is increased; and the cage has a small height-to-diameter ratio, and the number of cheese yarn layers is small, although it is easy to automate, but the production efficiency is low. The dyeing cylinder commonly used in the domestic cheese dyeing industry is a vertical dyeing cylinder. At present, the dyeing equipment and process level are low, the dyeing environment is high temperature and high humidity environment, chemical dyes and auxiliaries are flying, and the dyeing environment is bad; the production process requires the participation of the operators throughout the process, the workers are labor intensive and the body is vulnerable. In the dyeing process of the cheese yarn, the production process uses artificially set parameters, weighs the dyed materials, and the operator's personal experience affects the quality of the products. At the same time, the workers work in the harsh environment for a long time, which is prone to fatigue and tiredness. In turn, it causes mistakes; some workers are skipping production for piece-rate wages, resulting in many problems such as poor product quality and low production efficiency. Some related equipments used in the production line of the present invention can be found in the following cited patents: Application No.: 200720310752.3 200810224975.7 200820182717.2 201010547621.3, 201210035685.4, 201210060401.7, 201220069951.0, 201210065630.8, 201210062358.8, 201210060422.9.
