Abstract
The invention discloses an antiviral and antibiotic fiber, and a preparation method and an application thereof. The surface of the fiber is grafted with a monomer with a cationic functional group. The preparation method comprises the following steps: preprocessing a raw material fiber to improve the hydrophilic performance of the raw material fiber, fully infiltrating the preprocessed fiber in a grafting liquid containing a cationic functional group monomer, and carrying out an irradiation grafting reaction to obtain the antiviral and antibiotic fiber. The raw material fiber used by the preparation method can be a chemical fiber or natural fiber. Each of the anti-influenza virus rate and the anti-adenovirus rate of the antiviral and antibiotic fiber prepared in the invention is higher than 90%, and each of the anti-Staphylococcus aureus rate, the anti-Escherichia coli rate and the anti-Candida albicans rate of the antiviral and antibiotic fiber is higher than 96%. The antiviral and antibiotic fiber can be processed to form yarns, fabrics, nonwoven fabrics, nets and felts applied in medical, environmentally-friendly or/and personnel hygiene articles according to different uses.
Description
Technical field
The present invention relates to a kind of fiber, particularly relate to a kind of antiviral, anti-bacterial fibre and preparation method thereof and purposes.
Background technology
People are often subject in daily life bacterium and virus is invaded and harassed, and affect people's quality of life, seriously harm humans life and health even.Common textiles is owing to possessing anti-microbial property, attaches human secretion and become the good environment of bacterial growth, harm humans health in the wearing process of human body.The extensive use of anti-biotic material start in hospital bacterium infect prevention and attention and the protection to personal hygiene situation; In addition about virus, the SARS(serious acute respiratory system synthesis of outburst in 2003 is levied) virus, because it easily enters human body, infringement immune system by respiratory system, virus rapidly copy propagation ability makes it once once wreak havoc the whole world and cause very big fear.Just appeared at the novel coronavirus of multiple countries overseas a few days ago, more easily invaded immune system and replication capacity faster than SARS virus, State General Administration for Quality Supervision of China has sent notice of warning to this.In addition, also have the viral problems such as various animal influenza viruses, people's influenza virus, all need badly and seek a kind of efficient, safe, lasting antiviral material.
The same with most bacterium, virus is electronegative equally, by using positively charged protective materials, can produce absorption and iris action to virus and bacterium, and positively charged material itself has certain inhibition or killing action to bacterium and virus.The inventor has disclosed and has given wool quaternary ammonium cation group to realize antibacterial functions in Chinese patent document CN 102817238A.In addition, the disclosure of the invention of Chinese invention patent application prospectus CN 1609336A antiviral fiber and manufacture method and purposes, the fiber that this patent of invention provides is also the adsorption capacity of having utilized yin, yang ion pair virus and bacterium.But because its CATION antiviral fiber has used chloromethyl ether poisonous and may be carcinogenic in preparation process, human body is had to great damaging effect, because the hydrolysate formaldehyde of chloromethyl ether also may cause textiles residues of formaldehyde problem, therefore produce, apply and universal being restricted simultaneously.
In addition, part fiber is owing to having hydrophobic structure, and moisture pick-up properties is poor, as polypropylene fibre, wool, makes sweat rate of discharge unnecessary in human body wearing process slow, reduces snugness of fit.Therefore the hydrophilicity that improves this fibrid is an important difficult problem of textiles, and key is how to improve Hydrophilic Fiber can avoid too destroying the self structure of fiber simultaneously.Another reverse side, the fiber with hydrophobic structure is poor for the affinity of the monomer of hydrophilic cation functional group, has hindered function base the graft polymerization reaction of fiber is modified.Affect under the condition of fiber durability, stability not destroying fiber self structure, both when having realized antiviral, the antibiotic property of fiber, take into account the hydrophilicity that improves fiber, give healthful fabrics, comfortable dress is experienced, the innovation that is fabric treating is also technological difficulties.
Summary of the invention
The first object of the present invention is to provide a kind of antiviral, anti-bacterial fibre, by introducing and/or increase hydrophilic radical and improved the affinity of fiber and cationic functional groups, and finally introduced there is absorption and inhibition or kill virus, the cationic functional groups of bacterium ability, and there is antiviral and anti-microbial property efficient, lasting, wide spectrum.
Second object of the present invention is to provide a kind of preparation method of antiviral, anti-bacterial fibre, the method has been used the preparation process of nontoxic raw material reagent and recycling to reduce and has even avoided the injury to human body and the pollution to environment, uses UV light-induced reaction to enhance productivity, save energy consumption.
The 3rd object of the present invention is to provide prepared fibre for antiviral, antibacterial application.
For realizing above-mentioned first goal of the invention, the invention provides a kind of antiviral, anti-bacterial fibre, this fiber surface by graft polymerization reaction grafting there is the monomer of cationic functional groups.
