3 Principle
Dissolve spandex and acrylic with dimethylformamide, and leave wool and nylon to separate spandex, acrylic and wool, nylon; use sodium hypochlorite
Dissolve wool, surplus spandex, acrylic and nylon to separate wool and spandex, acrylic, nylon; dissolve acrylic with sodium thiocyanate, remaining wool, brocade
Polyurethane and spandex to separate acrylic and wool, nylon, spandex.
The percentage of wool is reduced by the percentage of wool and nylon to obtain the percentage of nylon; the percentage of spandex and acrylic is reduced.
The percentage of acrylic fiber is removed to obtain the percentage of spandex.
4 reagents
The reagents used were all chemically pure.
4.1 Distilled or deionized water.
4.2 petroleum ether, distillation range is 40 ° C ~ 60 ° C.
4.3 Dimethylformamide (density 0.950g/mL) (toxic, pay attention to protection).
4.4 1 mol/L sodium hypochlorite. Sodium hydroxide was added to a solution of about 1 mol/L sodium hypochlorite to make the content 5 g/L ± 0.5 g/L. this
The solution can be calibrated by iodometry to a concentration ranging from 0.9 mol/L to 1.1 mol/L.
4.5 50% sodium thiocyanate. 500g sodium thiocyanate plus 500mL water (toxic, pay attention to protection).
4.6 Dilute acetic acid. 5 mL of glacial acetic acid was diluted with water to 1000 mL.
5 Instruments and equipment
5.1 Constant temperature water bath. can maintain the temperature of 100 °C ± 2 °C.
5.2 Filtering device.
5.3 Constant temperature oven. The temperature can be maintained at 105 °C ± 3 °C.
5.4 Analytical balance. accuracy is 0.0002g.
