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 Kvalue unit, a central processing unit and a replenishment pump. The automatic calculation Kvalue 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 Kvalue unit transmits the Kvalue 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 provides super-hydrophobic fabrics and a preparation method thereof, and belong to the field of textiles. The super-hydrophobic fabrics are obtained by finishing Pickering emulsion formed by amphiphilic particles stabilizing low-surface-energy substances in water. Via a one-step finishing method using Pickering emulsion technology, facile preparation of durable super-hydrophobic fabrics is realized. The static contact angle between the finished fabric surfaces and water droplets is greater than 150 degrees, and the water droplets can roll off easily; and after being subjected to 30 times of standard washing tests, the finished fabrics still maintains excellent water repellency. In addition, the Pickering emulsion preparation and finishing process of the present invention are environmentally friendly, pollution-free, facile to operate and widely applicable.
