Method for preparing regenerated cellulose fibers having anti-bacteria, anti-mite and anti-mould functions and the use thereof

A method for preparing a regenerated cellulose fiber having anti-bacterial, anti-mite and anti-mould functions, comprising the steps of:

• (1) preparing a composite slurry;
• (2) blending the composite slurry and a denatured cellulose spinning dope to prepare a blended spinning dope;
• and
• (3) spinning the blended spinning dope and performing a post-treatment, thereby producing the regenerated cellulose fiber,
• wherein the composite slurry is prepared by a process comprising:
• i) blending a Fructus Foeniculi extract and a Litsea cubeba extract to obtain a blended powder;
• ii) mixing the blended powder obtained in step i) with a Thymus mongolicus Ronn essential oil to prepare an oily blended powder slurry and further emulsifying the oily blended power slurry to obtain an emulsion;
• and
• iii) reacting the emulsion obtained in step ii) with a urea-formaldehyde resin prepolymer to obtain the composite slurry.
