C. or more to fix the disperse dye to the polyphenylene sulfide fibers.

A digital control method is to accurately calculate the real-time addition amount of each dye in the solution replenishment system in the whole dyeing process based on the initial dyeing rate of each dye, and replenish the dye solution according to the real-time addition amount. A digital control system includes an automatic calculation K.sub.0,n value unit, a central processing unit and a replenishment pump. The automatic calculation K.sub.0,n value unit is composed of a dye solution concentration detection instrument, a sensor I and a BP neural network model. The BP neural network model is a BP neural network trained by a dye database. The automatic calculation K.sub.0,n value unit transmits the K.sub.0,n value to the central processing unit, calculates the replenishment amount through the central processing unit, and controls the replenishment pump to replenish the solution.

The present invention relates to a factory energy management system for the dyeing industry, which enables an energy management system (EMS) to be applied to dyeing industrial processes that over-consume energy, so as to reduce energy consumption by an optimized production management process. The present invention provides a factory energy management system (FEMS) for dyeing industry, in which an optimized production management system (POP) and an energy management system (EMS) are integrated into a single platform, and which enables real-time monitoring of energy usage in each of dyeing and finishing processes based on hardware, software and ICT-based monitoring and control technology, optimizes the use of energy in each process by analyzing aggregate date, and is configured to apply energy use factors and related data analysis and control processes in different manners depending on the characteristics of dyeing industrial processes.

A method of ring dyeing a yarn includes the steps of providing a cellulosic yarn chosen from the group consisting of open-end yarns and ring yarns. The yarn is immersed in only one sulfur dye box, the sulfur dye box having a sulfur concentration of 1 to 50 grams/liter. The yarn is skyed for less than 30 seconds after removal from the sulfur dye box. The yarn is rinsed in water after skying. The yarn is dyed in an indigo dye bath, with the indigo dye bath maintained at a pH of 10.8 and 12.8. The yarn is skyed after removal from the indigo dye box.

The method includes: obtaining fabric parameters of a fabric to be dyed; obtaining a fabric sample color; ascertaining whether predetermined pre-color-development color parameters corresponding to the fabric parameters and the fabric sample color exist in a field jet dyeing database; if not, generating temporary pre-color-development color parameters based on the fabric parameters and the fabric sample color, taking the temporary pre-color-development color parameters as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric; and if yes, taking the predetermined pre-color-development color parameters in the field jet dyeing database as contrast sample parameters, and generating field jet dyeing parameters according to the contrast sample parameters to dye the fabric. A color control device and a color control system are further provided.

The regulation method of easy dyeing for patterning a four-component chenille carpet pile combines raw filaments with different dyeing properties to prepare chenille yarns, and changes the combination modes and ratios of the raw filaments to prepare a four-component chenille carpet pile. The method realizes the heterochromaticity of the four-component pile through the uneven distribution of different dyes on the four-component raw filaments, and regulates the color difference of the four-component filaments after dyeing to form patterns with hazy, moderate and clear color mixing effects. The mixing of different colors dyed on the fibers in the four-component chenille carpet pile is spatial juxtaposition mixing, which forms a non-uniform and constant mixed color. According to the different mixing ratios of the color fibers and the interaction between the fiber hues, a composite color consisting of dominant and secondary hues is produced, thereby presenting a dynamic color.
