With the chitin and the derivative (about 1 μ m) thereof of 8 kilograms of pulverizing, put in the pure water, 1: 3 in proportion (weight ratio) makes it to be dispersed in the aqueous solution stand-by through grinding stirring.
After then cellulose viscose glue (9%～16% weight ratio) and chitin and the derivative aqueous solution thereof being mixed in proportion, mixed proportion (weight ratio) is 1: 15.
The spinning technique condition that contains the antibacterial viscose fiber of chitin and derivative thereof is: long 0.5～2.5m is soaked in spinning bath, bathe Wen Changwen, the coagulating bath component is sulfuric acid, sodium sulphate and zinc sulfate (weight ratio is conventional ratio), the spinning head hole count is 5000～20000 holes, aperture 0.07～0.1mm, spinning speed are 10～25 meters/minute.Behind the solidification forming, again through water washing, sulfuric acid on the flush away fiber, carbon disulfide, sulfate and other soluble impurity, can make the antibacterial viscose fiber that contains chitin and derivative thereof, fibre single thread fiber number 1.5dtex, fracture strength is 2.1～2.6cN/dtex, elongation 30%～50% (dry state), and fiber can be made into natural antibacterial underwear, underpants, Training wear, socks etc. through processing.
Example 6:
Chitin (logarithmic viscosity number is 4.5～5.5 deacetyl chitin) is put into 37%～50% sodium hydrate aqueous solution,, make alkaline chitin reacting 2 hours about 25 ℃ or under the lower condition.
Then alkaline chitin is added and mix (weight ratio is 1: 10) in the ice bath, temperature is remained on below 0 ℃, put into carbon disulfide, mix.The addition of carbon disulfide generally is no more than 1/4～1/2 of chitin content, and the reaction time is 2～6 hours.This is the process that a chitin sulfonation obtains the chitin sulphonic acid ester.Whole process must keep low temperature, and the time of staying can be 12～16 hours, and is complete in order to sulfonation.Filter deaeration then, make it to become the chitin sulphonic acid ester solution that can carry out spinning.When the chitin sulphonic acid ester was used to prepare chitin class article, its composition preferably contained hydroxide and receives 5%～9%, chitin 6%～8%.
The spinning technique condition that contains the antibacterial viscose fiber of chitin and derivative thereof is: long 2.0m is soaked in spinning bath, bathe Wen Changwen, the coagulating bath component is sulfuric acid, sodium sulphate and zinc sulfate (weight ratio is 1: 2: 1.5), spinning head hole count 10000 holes, aperture 0.08mm, spinning speed are 15 meters/minute.Behind the solidification forming, again through water washing, sulfuric acid on the flush away fiber, carbon disulfide, sulfate and other soluble impurity, can make the antibacterial viscose fiber that contains chitin and derivative thereof, fibre single thread fiber number 1.6dtex, fracture strength is 2.0～2.6cN/dtex, elongation 30%～50% (dry state), and fiber can be made into natural antibacterial underwear, underpants, Training wear, socks etc. through processing.
