Abstract
This invention relates to a reaction kettle colored chitose fiber production, which has following steps: during the dissolving of the colored chitose fiber spinning material, adding the dyestuff into the reaction kettle according to a certain proportion, then stirring the solution to make it into colored spinning slurries, and then through filtering, spinning, drawing-off, washing and drying the material becomes colored fiber. This invention is applied in large-scale production, and the operation method is simple.
Description
Technical field
The present invention relates to the field of colored fibre processing in the wet spinning process, is a kind of production technology of coloured chitosan fiber specifically.
Background technology
Chitin fiber is a kind of high polymer fibre that extracts from marine organisms.The method and the technology of at present not producing coloured chitosan fiber are used for the dyeing of textiles to chitin fiber, mainly contain the dyeing of chitin fiber blended yarn and two kinds of methods of piece dyeing finishing.But because chitin fiber is different with the coloring mechanism of other fibers, yarn and grey cloth after its blending can form very big aberration between the different materials when dyeing, influence the presentation quality of textiles.And this production technology can directly be produced coloured chitosan fiber, the aberration problem that occurs in the time of can solving chitin fiber and other fiber blends by the method that look spins.
Summary of the invention
The big problem of aberration that the present invention can form when solving chitin fiber and other fiber blends as dyeing textiles is invented a kind of technology for producing coloured chitosan fiber that in fiber production process dyestuff is added in the reactor.
Technical scheme of the present invention is, when the chitin fiber spinning material dissolves in reactor, required dyestuff is added in the reactor according to a certain percentage, constantly stir simultaneously, dyestuff is fully mixed with spinning material, and the fiber of producing like this is a colored fibre.The dyestuff that adds in the reactor, can be active, directly, the dyestuff of dispersion, neutral classification, or animals and plants pigment is as Tea Pigment, carthamin, or various pigment.The color of colored fibre can color code be as required freely adjusted the amount and the kind of the dyestuff that adds in reactor, method of operating is simple, convenient.
Its method step: earlier the raw material of spinning is added respectively by technological requirement, stir, it is fully dissolved, to join in the reactor with the good dyestuff of water-soluble in advance again, continue to stir, it is mixed, the spinning solution that mixes just can be used for spinning through after filtering.
Technique effect of the present invention is; produce colored fibre in this way; method of operating is simple; need not transform spinning equipment; every index of the colored fibre of producing all can reach spinning standard fibre requirement; reduce the operation of later yarn or piece dyeing finishing, be suitable in enormous quantities and large-scale production.
The specific embodiment
The present invention is further described below in conjunction with example:
(1) add the raw material for preparing in reactor, under the room temperature condition, start was stirred 2 hours, got black dyestuff 15g simultaneously, after fully dissolving with pure water 1000ml, poured in the reactor, continued to stir 2 hours.Treating just becomes coloured spinning solution after material dissolution fully, spinning solution is filtered again, and enters spinning process.Spinning solution is injected in the coagulating bath by spinnerets, further pass through drawing-off, washing, dehydration after, obtain the chitin fiber of black.
(2) add the raw material prepare in reactor, under the room temperature condition, start was stirred 2 hours, and the plain 20g of extracting yellow simultaneously after fully dissolving with the 1000ml pure water, pours in the reactor, continues stirring 2 hours.Treating just becomes coloured spinning solution after material dissolution fully, spinning solution is filtered again, and enters spinning process.Spinning solution is injected in the coagulating bath by spinnerets, further pass through drawing-off, washing, dehydration after, obtain yellow chitin fiber.
(3) add the raw material for preparing in reactor, under the room temperature condition, start was stirred 2 hours, got blue pigment 30g simultaneously, after fully dissolving with the 1500ml pure water, poured in the reactor, continued to stir 2 hours.Treating just becomes coloured spinning solution after material dissolution fully, spinning solution is filtered again, and enters spinning process.Spinning solution is injected in the coagulating bath by spinnerets, further pass through drawing-off, washing, dehydration after, obtain blue chitin fiber.
Above fiber more respectively through washing, is oiled, becomes coloured chitosan fiber after the drying, can be applicable to weaving or other purposes.
Claims (2)
1, a kind of technology for producing coloured chitosan fiber by reaction kettle process is characterized in that: the chitin fiber spinning material in the course of dissolution, adds required dyestuff in the reactor to according to certain ratio in reactor.
2, technology for producing coloured chitosan fiber by reaction kettle process according to claim 1 is characterized in that: the dyestuff in the reactor, can be active, directly, dispersion, neutral classification dyestuff, or animals and plants pigment, or various pigment.
