example 1
[0012] 1. See the table below for material selection and twisting process:
[0013]
[0014] 2. Double-bath dipping process is adopted for dipping. The dipping process is: dipping speed 30m / min, 1# drying zone temperature 150℃, heat fixing zone temperature 248℃, 2# drying zone temperature 180℃, 225℃, the temperature of the recovery zone is 240℃, the draft rate of the heat fixation zone is 100%, and the draft rate of the recovery zone is 100%.
[0015] 3. The dipping formula used is:
[0016] The prepreg is an impregnation solution of an isocyanate water dispersion blocked with end groups. The specific formula is: 2775kg of desalinated water, 150kg of isocyanate, and 30kg of epoxy resin.
[0017] The second immersion liquid adopts resorcinol-formaldehyde-based water-based adhesive system RFL liquid. The specific formula is: softened water 1444kg, caustic soda 3.0, resorcinol 50kg, formaldehyde 75kg (concentration 37%), ammonia 40kg (concentration 28%), 1170kg of latex.
example 2
[0019] 1. See the table below for material selection and twisting process:
[0020]
[0021] 2. Adopt the double-bath dipping process route for dipping. The dipping process is: dipping speed 31m / min, 1# drying zone temperature 150℃, heat fixing zone temperature 244℃, 2# drying zone temperature 180℃, The temperature in the recovery zone is 223°C, the temperature in the recovery zone is 238°C, the draft rate in the heat fixation zone is 100.5%, and the draft rate in the recovery zone is 100%.
[0022] 3. The dipping formula used is the same as that of Example 1.

[0024] 1. See the table below for material selection and twisting process:
[0025]
[0026] 2. Double-bath dipping process is adopted for dipping. The dipping process is: dipping speed 29m / min, 1# drying zone temperature 150℃, heat fixing zone temperature 250℃, 2# drying zone temperature 180℃, 226°C, the temperature in the recovery zone is 243°C, the draft rate in the heat fixation zone is 100.5%, and the draft rate in the recovery zone is 100%.
[0027] 3. The dipping formula used is the same as that of Example 1.
