Problems solved by technology

[0010] However, the existing technology lacks the optimization of the dehydration experimental method, and the investigation of the comprehensive influence of the surface tension of water and the surface energy of fiber products on the dehydration efficiency.
So that the dehydration efficiency is relatively low, and the amount of surfactant is relatively high

Abstract

The invention discloses a method for improving the dehydrating efficiency of fiber products by use of a fluorocarbon surfactant. Cationic fluorocarbon surfactants are added into a fiber product for dehydration, the concentration of the cationic fluorocarbon surfactants is 0.001-20g / L, and the dehydrating efficiency is judged according to the liquid ratio of the fiber product after dehydration treatment. According to the method, the surface tension of water can be effectively reduced, the surface energy of the textile in water is reduced, thereby improving the dehydrating efficiency under the common actions; the method has the characteristics of simplicity in operation, low using amount of the surfactants, high dehydrating efficiency and the like.

Description

technical field [0001] The invention relates to a method for improving the dehydration efficiency of fiber products by using fluorocarbon surfactants; specifically, it is a method for reducing energy consumption of fiber products in the dehydration and drying process by using fluorocarbon surfactants, belonging to the field of surfactant chemistry and Light industry energy saving and emission reduction field. Background technique [0002] With the transformation of China's economic development mode, the era of accelerating economic development at the cost of sacrificing the environment is gradually gone, and "energy saving and emission reduction" is an important breakthrough for my country to adjust its economic structure and realize the transformation of its economic development mode. Generally speaking, the light industry, especially the dyeing and finishing process, consumes a lot of energy, and most of it is used for washing, drying and heat treatment. Therefore, it is ...
