| titleOfInvention | Bio-based degradable polyester fiber and preparation method thereof |
| abstract | The invention relates to a bio-based degradable polyester fiber and a preparation method thereof, wherein the preparation method comprises the following steps: the bio-based dihydric alcohol and the bio-based dibasic acid are used as raw materials, a melt polycondensation method is adopted, the bio-based degradable polyester is prepared by esterification reaction, sectional pre-polycondensation reaction and final polycondensation reaction in sequence, and then the bio-based degradable polyester fiber is prepared by melt spinning forming; the sectional type pre-polycondensation reaction is divided into a first pre-polycondensation reaction and a second pre-polycondensation reaction according to the sequence, wherein polyethylene glycol is added in the first pre-polycondensation reaction process, and a monomer with a polyhydroxy structure is added in the second pre-polycondensation reaction process. The moisture regain of the finally prepared product is more than or equal to 2.0 percent, and the surface contact angle is less than or equal to 60 degrees. The preparation method has simple process, effectively reduces the residence time of the polycondensation reaction, reduces the energy consumption and material consumption, and has good economic benefit; the product of the invention has good degradability, good mechanical strength of fiber, high quality and great application prospect. |
