Embodiment 1
[0071] Water and oil repellent concentric sheath-core composite polyester fiber with a production line density of 2.50dtex.
[0072] Cortical component preparation:
[0073] The polyethylene terephthalate slices are pre-crystallized in a high-temperature fluidized bed at 190-200°C, and the crystallization time is 3-3.5 hours.
[0074] Trifluoropropyl methyl silicone oil and polyethylene terephthalate slices with a weight ratio of 15:85 are processed at 240°C by screw extrusion with high-temperature molten water to cool, pelletize and dry to make modified Non-toxic polyethylene terephthalate masterbatch.
[0075] The modified polyethylene terephthalate masterbatch is dried at a drying temperature of 150° C. and a drying time of 9-10 hours.
[0076] Preparation of core layer components:
[0077] The polyethylene terephthalate chips are vacuum-dried in a drier, cooled for half an hour, and then heated to dry.
[0078] The composite of the cortex and the core layer:
[0079] ...
Embodiment 2
[0089] Water and oil repellent concentric sheath-core composite polyester fiber with a production line density of 1.39dtex.
[0090] Cortical component preparation:
[0091] The polyethylene terephthalate slices are pre-crystallized in a high-temperature fluidized bed at 195-205°C, and the crystallization time is 3.5 hours.
[0092] Trifluoropropyl methyl silicone oil and polyethylene terephthalate slices with a weight ratio of 20:80 are processed at a high temperature of 235°C, cooled by screw extrusion with high-temperature molten water, pelletized and dried to produce modified Non-toxic polyethylene terephthalate masterbatch.
