Abstract
The invention discloses antibacterial, worm-expelling and fresh-preserving cotton cloth which is prepared by the steps of: dipping the pure cotton cloth in pepper water with concentration of 1% for at least 10min, and then spraying molecular chitin or chitosan with the amount of 2.5g/sq.m on the cotton cloth after the cotton cloth is dried. The cotton cloth treated by the method is made into various packaging supplies with a sterilizing rate of 60%, a worm-expelling rate of 98% and a valid period of up to half a year. The packaging bag made of the antibacterial, worm-expelling and fresh-preserving pure cotton cloth is safe and non-toxic for packaging cereal products and dried fruits, good for people's health, simple and convenient to make, and worth popularizing.
Description
Technical field
The present invention relates to manufacture the fabric of grain, dry fruit fresh-keeping packaging bag.
Background technology
Various grains are daily necessities of people, and various grains such as paddy, rice must utilize various packaging bag splendid attires from the source mill to the every family, how to make in the process of depositing fresh-keepingly, do not go mouldy, infestedly just become a big problem.Owing to there is not suitable packaging bag, annual because of go mouldy, the grain quantity of infested loss is very surprising, therefore and it is unsafe because of toxicity to take to send forth the agrochemical method, does not also have fresh-keeping effect, and needing badly provides a kind of safe and have a bag material of antibiotic, expelling parasite, fresh-keeping function.
Summary of the invention
Purpose of the present invention be exactly to provide a kind of and have antibiotic, expelling parasite, the grain dry fruit of safety and environmental protection is contained bag material again.Antibacterial, worm-expelling and fresh-preserving cotton cloth of the present invention is that cotton is soaked more than 10 minutes in pepper water, after drying, sprays molecular level response type chitin or shitosan again, consumption 2.5g/m
2Pepper water concentration 1%.The used pepper water of the present invention is that Chinese prickly ash is put into its weight is that 100 times water added heat soaking more than 10 minutes.Chitin is to remove calcium carbonate and protein in shrimp, the crab shell, the chitin that obtains after decolouring.Chitin behind deacetylation, promptly obtains shitosan again.Chitin is the natural polymer with strong positive charge, combines with the sialic acid of microorganism phosphide body, and the vital movement of energy restriction micro-organisms can't be survived by the bacterium of chitin and sialic acid parcel.Chitin oligosaccharide penetrates cells of microorganisms, suppresses transcribing of hereditary information, thereby stops cell division, breeding.Chitin and shitosan all are sheets or Powdered, and be nontoxic, tasteless, has potential good biologically active.Under normal condition, chitin and shitosan all are not dissolved in water, are subjected to the influence of factors such as molecular weight, deacetylation; its biologically active is uneven; extremely unstable, and the ionic group of shortage and various fiber combinations, for a long time; people give very big concern to the good material of this development prospect of chitin; but be limited by technical bottleneck, chitin can only be taken as primary raw materials always, and it is the inanimate object activity both; do not have fastness to washing again, in big industrial production, do not have practical function.For this reason, existing people transform the molecule of chitin, found a kind of efficient, convenient, excellent chitin product and operating procedure of P/C ratio, develop molecular level response type chitin---Chitosante, it can fully be dissolved in water at normal temperatures, and fully excites its biologically active, has group with various fiber-reactives, by effect and fiber permanent bond such as absorption, infiltration, set, bonds, give the fiber natural bioactive.Because Chinese prickly ash has natural disinsectization performance, the good bacteriostasis property of molecular level response type chitin in addition is so the freshness protection package of manufacturing with the present invention's cotton textiles cloth is used to deposit and packs various grains, dry fruit and just had good antibacterial, worm-expelling, fresh keeping property.Its sterilization rate is 60%, and deworming rates reaches 98%, is valid up to half a year.
The specific embodiment
Chinese prickly ash is dropped in the water of 100 times of its weight, pepper water is made in heating.With soaking more than 10 minutes in the textile cloth immersion pepper water, spray molecular level response type chitin or shitosan behind the airing again, consumption 2.5g/m
2, make various freshness protection packages with this cotton then and get final product.
Claims (1)
