Embodiment 1
[0043] A hydrophilic polyester fiber containing coffee charcoal, comprising a hydrophilic polyester fiber body and nanoscale coffee charcoal powder dispersed in the hydrophilic polyester fiber body. The content of nanoscale coffee charcoal powder is 0.5wt%, and its preparation method is:
[0044] (1) Preparation of hydrophilic polyester chips:
[0045]
[0046] Mix terephthalic acid and ethylene glycol in proportion to prepare slurry. The prepared slurry was mixed with the catalyst tetrabutyl titanate and then put into an esterification reactor for the first esterification reaction. The temperature of the first esterification reaction was 225° C., the reaction time was 4 hours, and the relative pressure of the reaction was 0 MPa. The by-product water is separated and collected by a fractionating tower, and the collection amount is measured with a graduated cylinder, and the theoretical value is calculated according to the reaction formula. When the collection amount of wat...
Embodiment 2
[0053] A hydrophilic polyester fiber containing coffee charcoal, comprising a hydrophilic polyester fiber body and nanoscale coffee charcoal powder dispersed in the hydrophilic polyester fiber body. The content of nanoscale coffee charcoal powder is 2wt%, and its preparation method is:
[0054] (1) Preparation of hydrophilic polyester chips:
[0055]
[0056] Mix terephthalic acid and ethylene glycol in proportion to prepare slurry. Mix the prepared slurry with ethylene glycol antimony, antioxidant 616, trimethyl phosphate and tris(nonylphenyl) phosphite in proportion and then add it to the esterification reactor for the first esterification reaction. The temperature of the esterification reaction is 230° C., the reaction time is 2.5 hours, and the relative pressure of the reaction is 0.25 MPa. The by-product water is separated and collected by a fractionating tower, and the collection amount is measured with a graduated cylinder, and the theoretical value is calculated a...
Embodiment 3
[0061] A hydrophilic polyester fiber containing coffee charcoal, comprising a hydrophilic polyester fiber body and nanoscale coffee charcoal powder dispersed in the hydrophilic polyester fiber body. The content of nanoscale coffee charcoal powder is 5wt%, and its preparation method is:
[0062] (1) Preparation of hydrophilic polyester chips:
[0063]
[0064] Mix terephthalic acid and ethylene glycol in proportion to prepare slurry. Mix the prepared slurry with antimony acetate, antioxidant 1010, antioxidant 168 and tris(nonylphenyl) phosphite in proportion and then add it to the esterification reaction kettle for the first esterification reaction. The first esterification reaction temperature is 230°C, the reaction time is 3h, and the relative pressure of the reaction is 0.35MPa. The by-product water is separated and collected by a fractionating tower, and the collection amount is measured with a graduated cylinder, and the theoretical value is calculated according to th...
