Abstract
The invention relates to a method for preparing antibacterial viscose fiber, which comprises the following steps: (1) soaking pulverized cellulose in alkaline solution, squeezing to 2.5 to 5 times the dry weight, mechanically pulverizing, aging, vacuuming, adding CS2, sulfonating, adding alkaline solution, dissolving, and mixing uniformly with alkaline solution of antibacterial medicine to obtain a uniform and stable spinning stock solution; and (2) filtering the spinning stock solution, adding to coagulating bath to form as-spun fibers, stretching the as-spun fibers, and post-treating with the bath solution to obtain the antibacterial viscose fiber. The antibacterial viscose fiber obtained by the invention has the advantages of high resistance to various kinds of bacteria, high mechanical strength and high antibacterial durability, and the fiber still has certain antibacterial effect after cleaning for multiple times. The antibacterial viscose fiber can be widely used in the field of various textiles that are required to have antibacterial and antivirus functions.
Description
Technical field
The invention belongs to the preparation field of chemical fibre, particularly relate to a kind of preparation method of antiviral viscose fiber.
Background technology
Not only storage level is big for cellulose in all substances of occurring in nature, and huge amount of recovery is arranged.Have only few cellulose to be made into fiber at present.Be used to make the cellulose amount of fiber and film, 4% of the cellulose output of producing no more than world industry.Along with the mankind to the deepening continuously and the worsening shortages of resources such as oil, coal, natural gas of nature understanding, cellulosic utilization also will enlarge gradually.Cellulose fibre is because raw cellulose can be changed into steam and carbon dioxide by biological decomposition or safe combustion, and the destruction environmental problem that is caused by discarded object is few.Therefore it is very necessary developing cellulose fibre.Make the semi-products of regenerated celulose fibre---the raw material source of pulp is quite extensive, from the needlebush of high-quality and cotton linter to leaf wood, fast growing wood, bamboo and various herbaceous plant (as bagasse, reed, jute bar etc.).
What produce cellulose fibers mainly adopted at present is viscose process, and this method is by making regenerated celulose fibre with cellulose through technical process such as dipping, squeezing, pulverizing, yellow, dissolving, filtration, deaeration, spinning, refining, oven dry.Viscose has a series of characteristics, and as good hygroscopicity, dyeing is antistatic easily, is easy to weaving processing, and the fabric variety of making is various, pattern is bright-coloured, and is comfortable and easy to wear, is particluarly suitable for the area dress of weather sweltering heat.And its fiber number and length can be regulated arbitrarily according to the requirement of purposes again, and this point is better than natural fabrics such as cotton, fiber crops, silk again.Along with the raising day by day of people's living standard, also more and more higher for the requirement of fabric, not only pursue comfortableness, and pay attention to more that it is functional.
Virus is minimum pathogenic microorganism, and more clinically disease is relevant with virus infections, and the latter is one of communicable disease that the incidence of disease is the highest in the world at present.According to the foreign statistic document announcement, nearly 3/4 infectious disease is caused by virus.Different virus infectionses causes different illness, needs different antiviral treatments.Some are having a strong impact on people's Health and Living in daily life by the disease that virus causes, even influence family life.More seriously some virus also may cause more serious disease, increase relevantly with several virus infectionses above-mentioned especially as the incidence of disease of having found cervical carcinoma in recent years, knurl becomes and the relation of infiltrating carcinoma also comes into one's own in HPV infection and invasive carcinoma of vulva, vulva verrucous carcinoma, the vagina epithelium.Therefore, exploitation antiviral fiber and articles for use are used for the virus killing effectively or suppress to be in contact with it, thereby play the effect of treatment and pre-anti-virus.
Regenerated celulose fibre is developed antiviral fibrid cellulose fiber and is seemed extremely important as a kind of fibrous raw material commonly used.The antibiotic fabric that adopts this antiviral fiber cellulose fiber to make has played virus and has intercepted the double function of killing, and can not cause virus to produce the resistance dissociant resistance to the action of a drug, do not cause human injury and environmental injury.Have many characteristics such as thorough, long-acting antiviral, the broad-spectrum antiviral of safety, sterilization.Antibiotic fabric provided by the invention can be widely used in medical mask, protective clothing, ward and have safeguard function textile product fields such as antibiotic, antiviral with various needs such as quilt covers.
