Background
In the textile industry, fibrilia has been widely used as a textile raw material by people due to its unique excellent properties of fast moisture absorption and dispersion, fast heat transfer and conduction, good luster, coolness and air permeability. However, the fibrilia has the defects that the fibrilia has poor wrinkle resistance and easy ironing resistance, and certain original antibacterial, mildewproof and ultraviolet-proof functions are greatly reduced due to chemical degumming and bleaching, so that the fibrilia is easy to mildew, easy to breed bacteria, weak in ultraviolet-proof function and the like.
At present, in order to improve the antibacterial, mildewproof and ultraviolet-proof functions of the fibrilia, the fibrilia needs to be modified by a modifier. The currently used antibacterial, mildewproof and ultraviolet-proof functional agents are mainly organic (synthetic) antibacterial, mildewproof and ultraviolet-proof functional agents, strictly speaking, most of the functional agents belong to the category of pesticides, have certain irritation and toxic and side effects on human skin, are mostly attached to the surfaces of fibrilia through an after-finishing method, and have poor water washing resistance and poor function durability.
Therefore, the above technical solutions have the following disadvantages in practical use: the traditional plant traditional Chinese medicine composition for the antibiosis and mildew prevention of microorganism immobilization generally has no function of a carbon source because the plant traditional Chinese medicine composition for the antibiosis and mildew prevention is generally emphasized not to be decomposed by microorganisms and has long validity period, and the function of immobilized denitrifying bacteria is limited because the denitrification nitrogen removal can not be realized due to the shortage of the carbon source in low carbon-nitrogen ratio wastewater.

The method for treating the fibrilia by adopting the antibacterial and mildewproof plant traditional Chinese medicine composition as the plant traditional Chinese medicine functional agent and the plant traditional Chinese medicine function lasting accelerant has the advantages of reliable and simple production process operation and unique production flow, and realizes the function combination of the fibrilia after the plant traditional Chinese medicine is treated.
It should be noted that, due to chemical degumming and bleaching, the original functions of the hemp fiber, such as certain antibacterial, mildew-proof and ultraviolet-proof functions, are greatly reduced, so that the hemp fiber is easy to mildew, easy to breed bacteria and weak in ultraviolet-proof function. Bacteria and molds are widely present in nature. Bacteria and mold can rapidly grow and propagate on the fibrilia or the textile thereof under proper environmental conditions, generate unsightly color, emit unpleasant odor and the like, and spread diseases through contact to influence the health of human bodies. The long-term excessive ultraviolet ray exposure of human body can cause the immune function to be reduced, the genetic factors to be deeply injured, and skin diseases, even skin cancer and the like. The currently used antibacterial, mildewproof and ultraviolet-proof functional agents are mainly organic (synthetic) antibacterial, mildewproof and ultraviolet-proof functional agents, strictly speaking, most of the functional agents belong to the category of pesticides, have certain irritation and toxic and side effects on human skin, are mostly attached to the surfaces of fibrilia through an after-finishing method, and have poor water washability and poor function durability. The antibacterial and mildewproof traditional Chinese medicine composition provided by the invention utilizes the traditional Chinese medicine extract composition as a modifier to modify the fibrilia, so that the effective components of the traditional Chinese medicine are 'implanted' into the fibrilia, the fibrilia is endowed with good antibacterial, mildewproof and ultraviolet-proof functions, and the requirements of consumers are met. The plant traditional Chinese medicine has a plurality of functions, such as antibiosis, mildew prevention, insect expelling, ultraviolet protection and the like, and the plant traditional Chinese medicine extract is a product formed by directionally obtaining and enriching one or more active ingredients in plants through a physical and chemical extraction and separation process by taking the plant traditional Chinese medicine as a raw material without changing the structures of the active ingredients. The plant traditional Chinese medicine extract is used as a natural plant functional agent, is safe and nontoxic, is green and environment-friendly, and has no pollution to the environment. In addition, tannin can promote functional components in the plant Chinese medicinal extract to combine with cellulose molecules, and enhance intermolecular force to maintain the persistence and stability of the plant Chinese medicinal function.
It is further explained that the pharmacological actions of the traditional Chinese medicine components in the antibacterial and mildewproof plant traditional Chinese medicine composition provided by the invention are as follows:
a) radix scutellariae, a dry root of scutellaria baicalensis of the family labiatae, the extract of which contains a plurality of active substances such as baicalein and baicalein, has a plurality of efficacies of clearing heat and drying dampness, purging fire and removing toxicity, resisting bacteria and stopping bleeding, improving immunity and the like, has excellent antibacterial effect on staphylococcus aureus, escherichia coli and candida albicans, has an excellent absorption effect on ultraviolet rays, especially UVB, and has a good function of absorbing ultraviolet rays.
b) The metabolic products of the mangosteen nutshell have various pharmaceutical activities, including antioxidant, anticancer, anti-inflammatory, antiallergic, antibacterial, antiviral and antimalarial activities. Meanwhile, the major active ingredient of mangosteen nutshell is mangostin, which has excellent ultraviolet ray shielding, namely ultraviolet ray radiation resistance.
c) Cortex Phellodendri is a dry bark of phellodendron amurense belonging to Rutaceae, also called cortex Phellodendri. The Chinese medicinal composition has the advantages of deep yellow color, extremely bitter taste, effects of clearing heat, drying dampness, purging fire and detoxifying, contains a large amount of alkaloids, bitter substances, steroids and the like in main components, has antibacterial and mildewproof effects, has a certain inhibition effect on staphylococcus aureus, escherichia coli, various moulds and the like, and can be combined with various plant Chinese medicaments in vivo and in vitro to play a role.
d) Tannin is a nontoxic organic polycarboxylic acid extracted from fructus kaki, fructus Punicae Granati or Galla chinensis. It can effectively promote the effective components of the plant extract to combine with the macromolecules of the fibrilia, so that the fibrilia treated by the plant traditional Chinese medicine has enhanced function and excellent water washing resistance, and is a natural function lasting accelerant. The tannic acid also has certain antibacterial property, has inhibiting effect on staphylococcus aureus, escherichia coli, klebsiella pneumoniae, pseudomonas aeruginosa and other strains, and can destroy cell membranes of the strains to achieve the antibacterial effect.
