The preparation method of Nanometer Copper bamboo-carbon viscose fibre of the present invention, be directly sent to the spinning of spinning board after fully being mixed by static mixer with viscose glue by Nanometer Copper bamboo charcoal solution, post processing obtains finished product; The flow velocity that described Nanometer Copper bamboo charcoal solution enters static mixer is greater than the flow velocity that viscose glue enters static mixer.
After viscose glue enters the pipeline of static mixer, can solidify and cause line clogging, the flow velocity of Nanometer Copper bamboo charcoal solution is greater than viscose glue, is introduced into pipeline, avoids entering of viscose glue, can not cause plugging.
The preparation method of described Nanometer Copper bamboo charcoal solution: first bamboo charcoal powder is added alkali, thickener, dispersant, be dispersed in water, through stirring, grinding evenly, obtains bamboo charcoal solution; Mix with Nanometer Copper master batch again, after stirring, leave standstill 30 ~ 120 min, the absorption of bamboo charcoal to Nanometer Copper is reached capacity.
Described dispersant is still dispersant polyacrylic acid sodium salt, and by weight, addition is 1 ~ 2%.Contribute to bamboo charcoal powder to be uniformly dispersed in water, and not free settling; Meanwhile, solution liquid bubble-free, does not affect the spinnability of fiber.
Described thickener is cellulose thickener, and by weight, addition is 1 ~ 5%.Object is the viscosity increasing bamboo charcoal solution, consistent with the viscosity of viscose glue and alkalinity, makes it to have compatibility with viscose glue, does not destroy, affects the stability of viscose glue, ensure that the spinnability of bamboo-carbon fibre.
Nanometer Copper bamboo charcoal solution of the present invention, Li Jing≤0.8 μm of bamboo charcoal is 4 ~ 6% containing alkali mass fraction, and viscosity is 30 ~ 70s(falling ball viscosity).
Viscosity 30 ~ 70 s(falling ball viscosity of viscose glue of the present invention), degree of ripeness 7 ~ 12mL, containing alkali 4 ~ 6%, the fine content 8 ~ 10% of first.
The consisting of of coagulating bath in described spinning process: sulfuric acid 100 ~ 120g/L, sodium sulphate 240 ~ 320g/L, zinc sulfate 1 ~ 8g/L, aluminum sulfate 1 ~ 10g/L; The temperature of coagulating bath is 40 ~ 50 DEG C.
The object adding aluminum sulfate in coagulating bath is: improve fibre strength, degree of stretching, and reduce zinc sulfate consumption, zinc ion is heavy metal, to water body, soil pollution seriously, and wastewater treatment difficulty.Adding of aluminum sulfate, realize low zinc or without zinc environmental protection spining technology, adopt the acid bath technique of the high salt of low acid simultaneously, avoid the problem of viscose glue easy fracture of wire because of impure.
The spinning mixture temperature of described spinning process is 10 ~ 20 DEG C.Because the viscosity of bamboo charcoal is lower, cause the overall viscosity of spinning solution to decline, therefore the setting outline of spinning temperature is lower than common process temperature.Reducing temperature can prevent spinning solution surface viscosity from declining, and improves the rheological property of spinning solution, improves the uniformity of bamboo-carbon powder distribution.
Be added with bamboo charcoal in fiber of the present invention, therefore spinnability and product strength and elongation can reduce, and simultaneously due to the reduction of uniformity, must reduce spinning speed, prevent broken end, improve spinnability.Different according to viscose filament yarn and short fiber technique, take following spinning technique respectively, ensure spinning good spinning property, fiber strength and elongation is high simultaneously.
