Embodiment 1
[0026] Regenerated nylon 6 fiber manufacturing process, it comprises the following steps:
[0027] Step 1, pulverizing the nylon 6 waste;
[0028] Step 2. In a closed stirring container, add a catalyst and a mixed solvent of ethanol and dichloroethane, and stir and dissolve at a temperature of 100° C. for 4 hours;
[0029] Wherein, the catalyst is a mixture of 30% sodium chloride and 70% ferric chloride, and the mass ratio of catalyst to nylon 6 waste in this embodiment is 0.2%.
[0030] In addition, in this embodiment, the mixed solvent is a mixture of 60% ethanol and 40% dichloroethane, and the mass ratio of the mixed solvent to nylon 6 waste is 1:1.
[0031] In this embodiment, the mixed catalyst composed of sodium chloride and ferric chloride is used, and then the mixed solvent composed of ethanol and dichloroethane is used to realize the dissolution of nylon 6 waste. Dissolution, and the amount of wastewater discharged after dissolution is very small, which can effectiv...
Embodiment 2
[0041] Regenerated nylon 6 fiber manufacturing process, it comprises the following steps:
[0042] Step 1, pulverizing the nylon 6 waste;
[0043] Step 2. In a closed stirring container, add a catalyst and a mixed solvent of ethanol and dichloroethane, and stir and dissolve at a temperature of 150° C. for 5 hours;
[0044] Wherein, the catalyst is a mixture of 30% sodium chloride and 70% ferric chloride, and the mass ratio of catalyst to nylon 6 waste in this embodiment is 0.4%.
[0045] In addition, in this embodiment, the mixed solvent is a mixture of 60% ethanol and 40% dichloroethane, and the mass ratio of the mixed solvent to nylon 6 waste is 1:1.
[0046] Step 3, after the dissolution, filter the undissolved solids in the solution;
[0047] Step 4, place the nylon 6 in the filtered solution in a crystallization tank to crystallize at a certain temperature, and the temperature in the crystallization tank is 45°C, cool and crystallize into a nylon 6 solid;
[0048] Step...
