From the test results of Examples 1-5 and Comparative Examples 1-2, it can be seen that the water-based polyurethane dispersion includes bio-polyurethane containing specific components, and the weight ratio of bio-polyester polyol to hydrophilic polyol is 2.7:1 to 5.3 The textile fabric that the embodiment 1～5 of 1:1 forms has good hygroscopicity and perspiration property, and can be applicable to fiber product. In contrast, the fabrics formed in Comparative Examples 1 and 2 in which the weight ratio of the biomass polyester polyol to the hydrophilic polyol in the aqueous polyurethane dispersion was not within the aforementioned range had poor moisture absorption or perspiration. It can be seen that when the weight ratio of the raw polyester polyol to the hydrophilic polyol in the water-based polyurethane dispersion is less than 2.7:1 (such as 2.4:1) or greater than 5.3:1 (such as 5.6:1), the water-based polyurethane The moisture absorption and sweat perspiration properties of the textiles prepared from the dispersion are not good.

As can be seen from Table 1, compared with the textiles (raw fabric (C/T)) that are not coated with aqueous polyurethane dispersions, the textiles (Example 1) prepared by aqueous polyurethane dispersions with 26% biomass content have Better moisture absorption and perspiration. It can be seen that, when the water-based polyurethane dispersion includes bio-polyurethane, the textile fabric prepared from the water-based polyurethane dispersion can have better hygroscopicity and sweat-wicking properties.

It can be seen from Table 2 that, compared with the textiles (original fabric (C/T)) without water-based polyurethane dispersion, the water-based polyurethane dispersion with 39% biomass content was coated by immersion, suction or spray printing. The textiles (Example 4-5) prepared by the method have better hygroscopicity and perspiration. In addition, the textiles produced by the jet-coating method had lower imbibition/sizing ratios compared to the textiles produced by the soaking imbibition method which had higher imbibition/sizing ratios. It can be seen that when the water-based polyurethane dispersion includes raw polyurethane, the textile made from the water-based polyurethane dispersion is suitable for the textile functional processing process of spray printing and coating type, and can reduce the usage of the water-based polyurethane dispersion. It can reduce energy consumption, water consumption and material consumption.

In summary, the water-based polyurethane dispersion of the present invention includes bio-polyurethane containing specific ingredients, and when the weight ratio of bio-polyester polyol to hydrophilic polyol is 2.7:1 to 5.3:1, the water-based polyurethane dispersion The textile made from liquid has good moisture absorption and perspiration, and can be applied to fiber products, which in turn can reduce the energy and material consumption required for manufacturing fiber products.
