Embodiment 1

[0026] The 99% purity borneol extract from the natural plant dipterocarp was dissolved in wormwood essential oil to prepare borneol-wormwood essential oil with a mass concentration of borneol of 5%.

[0027] In parts by weight, get 2 parts of toluene diisocyanate and 4 parts of borneol-wormwood essential oil solution and mix uniformly to form an oil phase, put this oil phase into 10 parts of water containing wt1% emulsifier polyvinyl alcohol (Mw1500), and use high-speed emulsification Machine emulsification, rotating speed 9200-9600r / min, emulsification 5min, get oil-in-water emulsion. To make the emulsion stable, add 10 parts of aqueous solution containing wt0.13% dispersant sodium alginate, add 4.6 parts of polyethylene glycol (Mw400-600) and 1% catalyst dibutyltin dilaurate at the same time, stir at room temperature for 2 hour, then the temperature was raised to 70°C, the chain extender ethylenediamine was added, and the stirring was continued for 1 hour to cure the wall ma...

Embodiment 2

[0032] The synthetic borneol with a purity of 98% was dissolved in wormwood essential oil to prepare borneol-wormwood essential oil with a mass concentration of borneol of 10%.

[0033] In parts by weight, get 5 parts of toluene diisocyanate and 5 parts of borneol-wormwood essential oil solution and mix uniformly to form an oil phase, put this oil phase into 12 parts of water containing wt1.2% emulsifier polyvinyl alcohol (Mw1500), use Emulsify with a high-speed emulsifier at a speed of 9200-9600r / min for 5 minutes to obtain an oil-in-water emulsion. To make the emulsion stable, add 10 parts of aqueous solution containing wt0.15% dispersant sodium alginate, add 5.4 parts of polyethylene glycol (Mw400-600) and 1% catalyst dibutyltin dilaurate at the same time, stir at room temperature for 2 hour, then the temperature was raised to 70°C, the chain extender ethylenediamine was added, and the stirring was continued for 1 hour to cure the wall material. The obtained slurry is wash...

Embodiment 3

[0038] The 99% purity borneol extract from the natural plant dipterocarp was dissolved in wormwood essential oil to prepare borneol-wormwood essential oil with a mass concentration of borneol of 5%.

[0039] In parts by weight, get 2 parts of toluene diisocyanate and 4 parts of borneol-wormwood essential oil solution and mix uniformly to form an oil phase, put this oil phase into 10 parts of water containing wt1% emulsifier polyvinyl alcohol (Mw1500), and use high-speed emulsification Machine emulsification, rotating speed 9200-9600r / min, emulsification 5min, get oil-in-water emulsion. To make the emulsion stable, add 10 parts of aqueous solution containing wt0.13% dispersant sodium alginate, add 4.6 parts of polyethylene glycol (Mw400-600) and 1% catalyst dibutyltin dilaurate at the same time, stir at room temperature for 2 hour, then the temperature was raised to 70°C, the chain extender ethylenediamine was added, and the stirring was continued for 1 hour to cure the wall ma...

Abstract

The invention provides a regenerated cellulose fiber containing microencapsulated anti-mite drugs and a preparation method thereof, wherein the regenerated cellulose fibers include viscose spinning stock solution and microencapsulated anti-mite drugs, wherein the microencapsulated anti-mite drugs The mass of mite medicine accounts for 0.05-2% of the mass of methyl cellulose in viscose spinning stock solution, and the mass of methyl cellulose accounts for 99.95-98% of the dry weight of regenerated cellulose fiber. as capsule core; its preparation method is to prepare borneol-wormwood essential oil solution first, and then prepare borneol-wormwood essential oil solution to obtain microcapsules through microencapsulation technology, then add microcapsules to viscose spinning stock solution, mix uniformly, and finally Regenerated cellulose fibers containing microencapsulated anti-mite drugs were prepared by viscose wet spinning process. The repelling rate of the present invention to dust mite is more than 95%, and has extremely strong anti-mite effect. The antibacterial rate of Staphylococcus aureus, Escherichia coli and other bacteria is over 90%.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a regenerated cellulose fiber containing microencapsulated anti-mite medicine and a preparation method thereof. Background technique [0002] Mites are small arthropods with a body length of usually 0.1-0.5 mm. The harm to the human body is mainly reflected in parasitism, stinging, poisonous stings, blood-sucking, allergic diseases, and spreading diseases. It can cause asthma, rhinitis, and dermatitis , tinea corporis and other diseases have caused serious harm to human health. [0003] Natural borneol is a crystal extracted from the resin and volatile oil of dipterocarp, an arbor plant of Dipterocarpaceae, also known as "borneol" or "plum slice", which is a nearly pure D-triterpene compound. The isomer synthesized by chemical methods is "synthetic borneol", and its quality standard should meet the requirements of the Chinese Pharmacopoeia. Borneol, hard ...
