Abstract
Official abstract text for this publication.
A temperature-sensing and humidity-controlling fiber includes a hydrophilic material and a temperature-sensing material. The temperature-sensing material has a lower critical solution temperature (LCST) between 31.2° C. and 32.5° C. when a light transmittance thereof is in a range from 3% to 80%, in which a wavelength of the light is between 450 nm and 550 nm.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fabricating method of a temperature-sensing and humidity-controlling fiber, comprising: providing an intrinsic temperature-sensing and humidity-controlling masterbatch comprising a hydrophilic material, a temperature-sensing material, and a polyester material, wherein the temperature-sensing material has a lower critical solution temperature (LCST) between 31.2° C. and 32.5° C. when a transmittance of light of the temperature-sensing material is in a range from 3% to 80%, and a wavelength of the light is between 450 nm and 550 nm; providing a base material masterbatch comprising the polyester material; and uniformly mixing the intrinsic temperature-sensing and humidity-controlling masterbatch and the base material masterbatch, such that the temperature-sensing and humidity-controlling fiber is formed. 2 . The fabricating method of the temperature-sensing and humidity-controlling fiber of claim 1 , wherein the temperature-sensing material comprises a structure represented by formula (1), wherein in the formula (1), X comprises a structure represented by formula (2) or formula (3): wherein a molar ratio of x and y is between 9:1 and 1:3, n is an integer between 7 and 120, and m is an integer between 10 and 1000. 3 . The fabricating method of the temperature-sensing and humidity-controlling fiber of claim 1 , further comprising: providing the temperature-sensing material, which comprises performing a modifying step on the hydrophilic material to form the temperature-sensing material. 4 . The fabricating method of the temperature-sensing and humidity-controlling fiber of claim 1 , further comprising: uniformly mixing the hydrophilic material, the temperature-sensing material, and the polyester material to form a mixture, and performing a powder refinement step, a powder dispersion step, and a kneading granulation step on the mixture, such that the intrinsic temperature-sensing and humidity-controlling masterbatch is formed, wherein a particle size of the temperature-sensing material after the powder refinement step and the powder dispersion step is between 1 μm and 500 μm.
