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...

Abstract

The invention provides a hydrophilic polyester fiber containing coffee carbon and a preparation method of the hydrophilic polyester fiber. The hydrophilic polyester fiber containing coffee carbon is characterized by comprising a hydrophilic polyester fiber body and nanoscale coffee carbon powder scattered in the hydrophilic polyester fiber body. The hydrophilic polyester fiber containing coffee carbon is good in hydrophilicity, can be used for deodorizing, warming and is dried quickly, and brings touch sensation of enjoying refreshing and comfort to consumers.

Description

technical field [0001] The invention relates to a hydrophilic polyester fiber containing coffee charcoal and a preparation method thereof. Background technique [0002] Since polyester and polyester fiber entered large-scale industrialization in the 1970s, the development speed is much faster than other synthetic materials and synthetic fibers. In 2010, the output of polyester fiber in my country was 25.13 million tons, accounting for about 81% of my country's chemical fiber output; It accounts for about 70% of the world's polyester fiber production. In the next 10 years, the world's polyester and polyester fiber will still maintain a growth rate of more than 3%, and polyester fiber will account for more than 60% of the world's total fiber products. The physical and mechanical properties of polyester fibers such as strength, abrasion resistance, resilience and dimensional stability can better meet the needs of various uses. However, polyester fiber is a typical hydrophobic ...
