Description

Technical Field

[0002] Modified fibers, also known as denatured fibers, are chemical fibers made by chemical or physical methods to denature the fibers. Fibers that have undergone physical denaturation include shaped fibers, deformed fibers, and composite fibers. Fibers modified by chemical methods include grafted fibers, copolymer fibers, and fibers denatured by chemical post-treatment.

[0003] During preparation, the required modifier is dissolved in a solvent in a certain proportion to form a modified solution of corresponding proportion. After degreasing, the fiber is immersed in the modified solution. After a certain period of time, the fiber is taken out and evenly distributed by spraying or spin coating. Finally, the fiber is dried. The fiber can be prepared from the raw material slurry, which needs to be constantly stirred and mixed during production. However, after the raw materials are mixed, the inner wall of the stirring tank will also be sticky with the slurry, which is inconvenient to clean.
