Description
Technical field
The invention provides the preparation technology of a kind of Plant fiber's spinning, particularly relate to a kind of from Folium Artemisiae Argyi bar, extract viscose glue
Technique, belongs to textile technology field.
Background technology
Folium Artemisiae Argyi is perennial herb or slightly becomes suffruticose plant, and plant has enhanced aroma.Folium Artemisiae Argyi has with Chinese life
Close relationship, often to when the Dragon Boat Festival, Chinese mugwort is always placed in family with " avoiding evil spirits " by people, withered after strain body soaked
Stifling to reach disinfectant antipruritic, the multiplex Ai Shui of puerpera has a bath or stifling.Compendium of Material Medica except record " Herba Artemisiae Sieversianae " and " in vain Chinese mugwort '
Outward, also stated that " Artemisia argyi Levl. et Van. var. argyi cv. Qiai " (producing Qi Zhou, Xin Zhou town, Qichun County, modern Hubei Province), can be used as medicine.All herbal medicine, have warming the meridian,
Dry, cold expelling, hemostasis, antiinflammatory, relieving asthma, cough-relieving, the effect such as antiabortive, antiallergic.Successive dynasties doctor's nationality is recited as " hemostasis
Key medicine ", be again one of gynecological's common medicine, control the gynecological diseases of deficient cold type it is further preferred that, control again senile chronic bronchitis and heavy breathing
Breathe heavily, mother and baby in puerperal can be prevented and treated during bathing to boil water and catch, or pharmacy medicated pillow, medicine vest, preventing and treating senile chronic props up gas
Pipe inflammation or asthma and cold of insufficiency type and stomachache etc.；Folium Artemisiae Argyi is dried and smashs to pieces " Folium Artemisiae Argyi ", and moxa roll processed, for moxa-moxibustion, can be made " ink paste " again
Raw material.In addition herb make parasite killing pesticide or smoke cigarette make room sterilization, parasite killing.
People are mainly limited to Folium Artemisiae Argyi leaf to the utilization of Folium Artemisiae Argyi at present, and most Folium Artemisiae Argyi bar is then to be dropped or concentrate
Burn, the most not only cause waste but also measure greatly the burning of Folium Artemisiae Argyi bar and also environment is caused pollution.How can be bigger
That changes utilizes Folium Artemisiae Argyi, becomes a problem that urgently people solve.
