Embodiment 1
[0031] A method for improving the dehydration efficiency of fiber products using fluorocarbon surfactants provided in this example includes the following steps: 1) weigh the dry weight of the fiber products and put them into a centrifuge tube with sieve holes; 2) place the fiber products The centrifuge tube was soaked in the cationic fluorocarbon surfactant YF-007 solution with a concentration of 0.1g / L (purchased from Hubei Youshida Technology Co., Ltd.), the molecular formula is: C 8 f 17 SO 2 NH(CH 2 ) 3 N(CH 3 ) 3 I - , after soaking for 5 minutes, take out the centrifuge tube containing the fiber product and place it on the stand until there is no water dripping; 3) Put the centrifuge tube containing the fiber product obtained in step 2) into a centrifuge and centrifuge at a speed of 510 rpm for 1 min 4) Take out and weigh the fiber product in the centrifuge tube after centrifugation in step 3), and calculate the liquid-carrying rate, and judge the dehydration effic...
Embodiment 2
[0034]A method of using fluorocarbon surfactants to improve the dehydration efficiency of fiber products provided in this example includes the following steps: 1) weigh the dry weight of the fiber products and put them into a centrifuge tube with sieve holes; 2) place the fiber products The centrifuge tube was soaked in the cationic fluorocarbon surfactant YF-134 solution (purchased from Hubei Youshida Technology Co., Ltd.) with a concentration of 0.05g / L, and the molecular formula was: C 8 f 17 SO 2 NH(CH 2 ) 4 N(CH 3 ) 3 I - , after soaking for 5 minutes, take out the centrifuge tube containing the fiber product and place it on the stand until there is no water dripping; 3) Put the centrifuge tube containing the fiber product obtained in step 2) into a centrifuge and centrifuge at a speed of 510 rpm for 1 min 4) Take out and weigh the fiber product in the centrifuge tube after centrifugation in step 3), and calculate the liquid-carrying rate, and judge the dehydration ...
Embodiment 3
[0037] A method of using fluorocarbon surfactants to improve the dehydration efficiency of fiber products provided in this example includes the following steps: 1) weigh the dry weight of the fiber products and put them into a centrifuge tube with sieve holes; 2) place the fiber products The centrifuge tube was soaked in the anionic fluorocarbon surfactant YF-95 solution with a concentration of 1g / L (purchased from Hubei Youshida Technology Co., Ltd.). After soaking for 5min, the centrifuge tube containing the fiber product was taken out and placed on the rack 3) Put the centrifuge tube containing the fiber product obtained in step 2) into the centrifuge at a speed of 510rpm for 1 min and take it out; 4) Centrifuge the fiber in the centrifuge tube in step 3) The product is taken out and weighed, and the liquid-carrying rate is calculated, and the dehydration efficiency is judged by the liquid-carrying rate. The fiber product described in this embodiment adopts fiber-containing ...
