Example Embodiment
[0042] Example 1
[0043] A hydrophilic polyester fiber containing coffee charcoal comprises a hydrophilic polyester fiber body and nano-level coffee charcoal powder dispersed in the hydrophilic polyester fiber body. The content of nanometer coffee charcoal powder is 0.5wt%, and the preparation method is as follows:
[0044] (1) Preparation of hydrophilic polyester chips:
[0045]
[0046] The terephthalic acid and ethylene glycol are mixed in proportion to prepare slurry. The prepared slurry is mixed with the catalyst tetrabutyl titanate and then added to the esterification reactor for the first esterification reaction. The first esterification reaction temperature is 225° C., the reaction time is 4 hours, and the relative pressure of the reaction is 0 MPa. The by-product water is separated and collected by a fractionation tower. The collected amount is measured by a graduated cylinder. The theoretical value is calculated according to the reaction formula. When the collected amoun...

[0052] Example 2
[0053] A hydrophilic polyester fiber containing coffee charcoal comprises a hydrophilic polyester fiber body and nano-level coffee charcoal powder dispersed in the hydrophilic polyester fiber body. The content of nanometer coffee charcoal powder is 2wt%, and the preparation method is:
[0054] (1) Preparation of hydrophilic polyester chips:
[0055]
[0056] The terephthalic acid and ethylene glycol are mixed in proportion to prepare slurry. The prepared slurry is mixed with the mixture of ethylene glycol antimony, antioxidant 616, trimethyl phosphate and tris(nonylphenyl) phosphite in proportion and then added to the esterification reactor for the first esterification reaction. The esterification reaction temperature is 230°C, the reaction time is 2.5h, and the relative pressure of the reaction is 0.25MPa. The by-product water is separated and collected by a fractionation tower. The collected amount is measured by a graduated cylinder. The theoretical value is ...

[0060] Example 3
[0061] A hydrophilic polyester fiber containing coffee charcoal comprises a hydrophilic polyester fiber body and nano-level coffee charcoal powder dispersed in the hydrophilic polyester fiber body. The content of nanometer coffee charcoal powder is 5wt%, and the preparation method is:
[0062] (1) Preparation of hydrophilic polyester chips:
[0063]
[0064] The terephthalic acid and ethylene glycol are mixed in proportion to prepare slurry. The prepared slurry is mixed with antimony acetate, antioxidant 1010, antioxidant 168 and tris(nonphenyl) phosphite in proportions and then added to the esterification reactor for the first esterification reaction. The first esterification reaction temperature is At 230°C, the reaction time was 3h, and the relative pressure of the reaction was 0.35MPa. The by-product water is separated and collected by a fractionation tower. The collected amount is measured by a graduated cylinder. The theoretical value is calculated accordi...
