Abstract
The invention provides a preparation method of a chitin antibacterial sanitary towel, comprising the following steps of: preparing chitin antibacterial fibers; mixing and loosening the chitin antibacterial fibers and ES (Ethylene-Propylene) fibers in a mass ratio of (20-40%): (80-60%) through a loosening machine; sizing by hot air according to gram gravity requirements, paving a net, winding and cutting to prepare a chitin antibacterial non-woven fabric; in a process of manufacturing the sanitary towel, preparing a core material and spraying glue on a chitin antibacterial non-woven fabric material; then molding a concave channel and covering a bottom film; sticking back-limb release paper; sealing the periphery and sizing; externally cutting and molding; covering a film and an easy patch; transversely sealing and cutting off to prepare the chitin antibacterial sanitary towel. The chitin antibacterial sanitary towel has the advantages of excellent antibacterial effect, water-washing resistance and easiness for degradation.
Description
Technical field
The present invention relates to a kind of chitin antibacterial sanitary towel and preparation method thereof.
Background technology
In the sanitary towel field, the antimicrobial technology of using at present has inorganic and organic.But organic anti-bacterial mainly is that chemicals is antibiotic, and is very large to the side effect of environmental effect and human body, also has not water-wash resistance; Inorganic antibacterial mainly uses the metal ion antimicrobial technology, such as nanometer silver, zinc, copper ion, but can not degrade contaminated environment.
Summary of the invention
The purpose of this invention is to provide a kind of chitin antibacterial sanitary towel and preparation method thereof, the good water-fastness and easy degraded of antibacterial effect.
In order to solve the problems of the technologies described above, chitin antibacterial provided by the invention sanitary towel and preparation method thereof is achieved in that
The preparation method of a kind of chitin antibacterial sanitary towel, preparation chitin antibacterial fiber, mass ratio is that chitin antibacterial fiber and the ES fiber of 20% ~ 40%:80% ~ 60% mixes through the opener shredding, require to set through hot air shaping, lapping, rolling, cut according to grammes per square metre, make chitin biological antibiotic non-woven fabrics; When making sanitary towel, make core material after, glue spraying is covered chitin biological antibiotic nonwoven cloth material; Then, recessed road is shaped, and covers counterdie, pastes the backlimb release paper, and week is sealed typing, and peplos and fast easily subsides are covered in circumscribed shaping, and chitin biological antibiotic sanitary towel is made in horizontal sealing, cut-out.
Optionally, described preparation chitin antibacterial fiber comprises: the chitin that extracts is dissolved with ionized water at normal temperatures, then add in the enamel stirring reaction pot, add acetum and urea liquid, stir 15min, make mixed liquor; Obtain after filtering wire-drawing solution, the wire-drawing solution that obtains is sprayed in the tank that sodium hydroxide and alcoholic solution are housed, solidified 1.5 ~ 2.5 hours; After wire drawing after will solidifying is washed with warm water, with wire drawing machine burning is rolled up in 800 ~ 1200 times of spray webbing stretchings afterwards, under tension state, cut into the fiber of 3.5cm length with the oven dry of 75 ~ 85 temperature after 30 minutes, make sanitary towel's chitin antibacterial fiber.
Optionally, the step of described chitin extraction comprises: in soaking at room temperature Crusta Penaeus seu Panulirus or Carapax Eriocheir sinensis 24h, then wash the precipitate 3 times in the above-mentioned hydrochloric acid with 5% ~ 6% hydrochloric acid; Precipitation through washing is boiled 4 ~ 6h with 3% ~ 4%NaOH; Then soak 1 ~ 2h with 0.5% potassium permanganate, decolour; Then use nitric acid at 60 ~ 70 degrees centigrade of lower 30 ~ 40min of processing, get white crude product; Washing and drying gets the chitin finished product.
Optionally, after described precipitation through washing is boiled 4 ~ 6h with 3% ~ 4%NaOH, use aseptic water washing, remove residual alkali and protein.
Optionally, the potassium permanganate of described usefulness 0.5% is processed 1 ~ 2h, after decolouring, soaks with oxalic acid, then collecting precipitation.
The present invention also provides a kind of chitin antibacterial sanitary towel, and the surfacing of described chitin antibacterial sanitary towel is that chitin antibacterial fiber and the ES fiber of 20% ~ 40%:80% ~ 60% made by mass ratio.
Chitin is to be raw material with Portunustrituberculatus Penaeus seu panulirus carapace, obtains chitin through the special process extraction, and chitin and special solvent are mixed and made into wire-drawing solution, makes the chitin antibacterial fiber through wire drawing machine, is used as the antibiotic of sanitary towel.
Chitin antibacterial provided by the invention sanitary towel, the service property (quality) ratio is the chitin antibacterial fiber of 20% ~ 40%:80% ~ 60% and the sanitary towel that the ES fiber is made, and soaks to have no mouldy, jaundice in 2 years in water, does not produce the bacteria breed phenomenon.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Elder generation's chitin extraction finished product in soaking at room temperature Crusta Penaeus seu Panulirus or Carapax Eriocheir sinensis 24h, is then washed the precipitate 3 times in the above-mentioned hydrochloric acid with 5% ~ 6% hydrochloric acid; Precipitation through washing is boiled 4 ~ 6h with 3% ~ 4%NaOH; Use aseptic water washing, remove residual alkali and protein; Then soak 1 ~ 2h with 0.5% potassium permanganate, decolour; Then soak with oxalic acid, then collecting precipitation; Then use nitric acid at 60 ~ 70 degrees centigrade of lower 30 ~ 40min of processing, get white crude product; Washing and drying gets the chitin finished product.
Then, preparation chitin antibacterial fiber: the chitin that extracts is dissolved with ionized water at normal temperatures, then add in the enamel stirring reaction pot, add acetum and urea liquid, stir 15min, make mixed liquor; Obtain after filtering wire-drawing solution, the wire-drawing solution that obtains is sprayed in the tank that sodium hydroxide and alcoholic solution are housed, solidified 1.5 ~ 2.5 hours; After wire drawing after will solidifying is washed with warm water, with wire drawing machine burning is rolled up in 800 ~ 1200 times of spray webbing stretchings afterwards, under tension state, cut into the fiber of 3.5cm length with the oven dry of 75 ~ 85 temperature after 30 minutes, make sanitary towel's chitin antibacterial fiber.
