Abstract
The invention discloses a kind of method for chemically degumming jute and red ramie fiber, including being handled jute-kenaf fibres using lye, auxiliary agent Na2SiO3 and Na2SO3 are added in the lye into treatment fluid, wherein, the dosage of the alkali is the 10% of jute-kenaf fibres weight, the dosage of auxiliary agent Na2SiO3 and Na2SO3 are the 5% of jute-kenaf fibres weight, and treatment fluid bath raio is 3:10.The present invention adds auxiliary agent Na2SiO3 and Na2SO3 in traditional alkali scouring solution, and Na2SiO3 has and prevents cellulose oxidation and make the double action of strength reduction because cellulose is aoxidized；Na2SO3 to it is various add lustre to bases have reduction, and can bleached fiber, add Na2SiO3 and Na2SO3 auxiliary agents after treatment fluid can improve colloid removal rate and fibre fineness, protect the intensity of jute-kenaf fibres, and improve the whiteness of fiber.The present invention be facts have proved compared with traditional alkali degumming, the fineness of the jute-kenaf fibres after degumming improves 50%, and intensity increases 65%.
Description
Technical field
The present invention relates to a kind of Degumming methods of flaxen fiber, and in particular to a kind of method for chemically degumming jute and red ramie fiber.
Background technology
Chemical Degumming method is current main degumming method of bast fiber, advantage have usually time it is short, it is high in machining efficiency,
Effect can be obtained in a short time and production is not subject to seasonal restrictions.Chemical Degumming method use scope is very wide, cannot be only used for ramie,
The full degumming of hemp, be also applied for flax, hemp, tossa half deguming.
Currently, chemical Degumming method is mainly two kinds of acid processing and alkali process, because cellulose is easy to be hydrolyzed by acid, and
It is easily oxidised agent oxidation, so generally using the concise degumming process of alkali to cellulose fibre.However, although aqueous slkali will not divide
The cellulose in jute-kenaf fibres is solved, but the cellulose under highly basic effect in fiber can be damaged or aoxidize, to influence Huang
The intensity of bastose reduces the spinning property of jute-kenaf fibres.
For the present invention precisely in order to overcoming above-mentioned deficiency, the technical problem to be solved is that provide a kind of change of jute-kenaf fibres
Degumming method is learned, which does not interfere with the intensity of jute-kenaf fibres, reduce the spinning property of jute-kenaf fibres.
Invention content
In order to solve the above technical problems, the technical solution adopted in the present invention is as follows：
A kind of method for chemically degumming jute and red ramie fiber, including jute-kenaf fibres are handled using lye, described
Auxiliary agent Na2SiO3 and Na2SO3 are added in lye into treatment fluid, wherein the dosage of the alkali is jute-kenaf fibres weight
10%, the dosage of auxiliary agent Na2SiO3 and Na2SO3 are the 5% of jute-kenaf fibres weight, and treatment fluid bath raio is 1:20.
Wherein, preferably, the alkali is NaOH, the ratio of the auxiliary agent Na2SiO3 and Na2SO3 are 3:10.
Bleeding agent is also added in the treatment fluid；The bleeding agent is selected from PST or JFC；The additive amount of the bleeding agent
For the 0.5-5% of yellow bluish dogbane weight.
In order to be conducive to processing of the follow-up lye to jute-kenaf fibres, before being handled jute-kenaf fibres using lye
It is pre-processed, which includes the combination of one or more of water-bath, acid bath or hydrogen peroxide dipping.
Advantageous effect：The present invention adds auxiliary agent Na2SiO3 and Na2SO3, Na2SiO3 tools in traditional alkali scouring solution
Having prevents cellulose oxidation and makes the double action of strength reduction because cellulose is aoxidized；Na2SO3 has the various bases that add lustre to
Reduction, and can bleached fiber, add Na2SiO3 and Na2SO3 auxiliary agents after treatment fluid can improve colloid removal rate and fibre
Fineness is tieed up, protects the intensity of jute-kenaf fibres, and improve the whiteness of fiber.The present invention be facts have proved compared with traditional alkali degumming,
The fineness of jute-kenaf fibres after degumming improves 50%, and intensity increases 65%.
Specific implementation mode
The yellow bluish dogbane raw ramie bought from market is unpacked, about 0.5 kilogram of wisp one by one is divided into, uses concentration first
Acid bath pretreatment, bath raio 1 are carried out for 95% or more the concentrated sulfuric acid:20；
Prepare chemical degumming process liquid：Take 10% NaOH of yellow bluish dogbane weight, 5% auxiliary agent of yellow bluish dogbane weight
The weight ratio of Na2SiO3 and Na2SO3, wherein Na2SiO3 and Na2SO3 are 3:10, the water of itself and 15 times of yellow bluish dogbane weight is mixed
Synthesize chemical Degumming treatment fluid；
Above-mentioned chemical Degumming treatment fluid is warming up to 100 DEG C, immerses yellow bluish dogbane thereto, keeps carrying out chemistry in 120 minutes
Degumming process；
Treated jute-kenaf fibres according to the prior art strike that fiber crops handles, clean, to be dehydrated quality to obtain the final product preferable
The fineness of jute-kenaf fibres, the jute-kenaf fibres is 583 public branch, intensity 2.56cN/dtex.
