Description
Technical field
The present invention relates to a kind of chitin antibacterial sanitary towel and preparation method thereof.
Background technology
In sanitary towel field, the antimicrobial technology of application at present has inorganic and organic.But organic anti-bacterial mainly chemicals is antibacterial, very large to the side effect of environmental effect and human body, also have not water-wash resistance; Inorganic antibacterial mainly uses metal ion antimicrobial technology, as nanometer silver, zinc, copper ion, but can not degrade, contaminated environment.
Summary of the invention
The object of this invention is to provide a kind of chitin antibacterial sanitary towel and preparation method thereof, antibacterial effect is good water-fastness and easily degrade.
In order to solve the problems of the technologies described above, chitin antibacterial sanitary towel provided by the invention and preparation method thereof is achieved in that
A kind of preparation method of chitin antibacterial sanitary towel, prepare chitin antibacterial fiber, mass ratio is that the chitin antibacterial fiber of 20% ~ 40%:80% ~ 60% and ES fiber mix through opener shredding, require setting through hot air shaping, lapping, rolling according to grammes per square metre, cut, make chitin biological antibiotic non-woven fabrics; When making sanitary towel, after making core material, glue spraying covers chitin biological antibiotic nonwoven cloth material; Then, recessed channel is shaped, and covers counterdie, pastes backlimb release paper, all envelope sizings, circumscribed shaping, and cover peplos and fast easily subsides, horizontal sealing, cut-out, make chitin biological antibiotic sanitary towel.
Optionally, described chitin antibacterial fiber of preparing comprises: dissolved with ionized water at normal temperatures by the chitin extracted, then add in enamel stirring reaction pot, add acetum and urea liquid, stir 15min, make mixed liquor; Obtain wire-drawing solution after filtering, the wire-drawing solution obtained is sprayed in the tank that sodium hydroxide and alcoholic solution are housed, solidify 1.5 ~ 2.5 hours; After the wire drawing warm water washing after solidifying, spray webbing stretched after 800 ~ 1200 times with wire drawing machine and roll up burning, cut into the fiber of 3.5cm length after using 75 ~ 85 temperature to dry 30 minutes in a tensioned state, make sanitary towel's chitin antibacterial fiber.
Optionally, the step of described chitin extraction comprises: with 5% ~ 6% hydrochloric acid in soaking at room temperature Crusta Penaeus seu Panulirus or Carapax Eriocheir sinensis 24h, then washes precipitate in above-mentioned hydrochloric acid 3 times; Precipitation through washing boils 4 ~ 6h with 3% ~ 4%NaOH; Then soak 1 ~ 2h with the potassium permanganate of 0.5%, decolour; Then use nitric acid to process 30 ~ 40min under 60 ~ 70 degrees Celsius, obtain white crude; Washing and drying, obtains chitin finished product.
Optionally, after the described precipitation through washing boils 4 ~ 6h with 3% ~ 4%NaOH, with aseptic water washing, the alkali that removing is residual and protein.
Optionally, the potassium permanganate process 1 ~ 2h of described use 0.5%, 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 the chitin antibacterial fiber of 20% ~ 40%:80% ~ 60% and ES fiber are made by mass ratio.
Chitin is raw material with Portunustrituberculatus Penaeus seu panulirus carapace, obtains chitin, chitin and special solvent are mixed and made into wire-drawing solution, make chitin antibacterial fiber through wire drawing machine, be used as the antibacterial of sanitary towel through special process extraction.
Chitin antibacterial sanitary towel provided by the invention, service property (quality) ratio is the sanitary towel that the chitin antibacterial fiber of 20% ~ 40%:80% ~ 60% and ES fiber are made, soak in water within 2 years, have no mouldy, jaundice, do not produce bacteria breed phenomenon.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, 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, be not intended to limit the present invention.
First chitin extraction finished product, with 5% ~ 6% hydrochloric acid in soaking at room temperature Crusta Penaeus seu Panulirus or Carapax Eriocheir sinensis 24h, then washes precipitate in above-mentioned hydrochloric acid 3 times; Precipitation through washing boils 4 ~ 6h with 3% ~ 4%NaOH; With aseptic water washing, the alkali that removing is residual and protein; Then soak 1 ~ 2h with the potassium permanganate of 0.5%, decolour; Then soak with oxalic acid, then collecting precipitation; Then use nitric acid to process 30 ~ 40min under 60 ~ 70 degrees Celsius, obtain white crude; Washing and drying, obtains chitin finished product.
