Abstract

The invention relates to a process for preparing silk functional fabric, which grafts the cyclodextrin onto the silk fiber through the chemical bond to obtain the silk functional fabric product with cyclodextrin solid chirality hydrophobic cavity, wherein the process can be used for preparing fabric with aromatic and medical health care functions and also can be used in the fields of molecule identification, waste water purification, artificial enzyme system forming and pharmaceutical slow releasing.

Description

technical field [0001] The invention relates to a method for preparing silk functional fibers, which belongs to the technical field of textile fiber preparation. Background technique [0002] Silk clothing made of silk material has been loved by people for thousands of years due to its unique texture, but with the progress of society and the improvement of living standards, people have more and more requirements for the diversity of clothing. , due to the continuous emergence of new fiber materials, these silk materials have been more and more challenged. How to add new properties without changing the original excellent properties of silk has become more and more important for increasing the added value of silk products and promoting their commercial sales. [0003] Known silk fibers contain active groups such as hydroxyl, carboxyl, and amino groups, so other monomers can be inserted through grafting, and new properties can be introduced without changing the original proper...
