Description
Technical field
The invention belongs to the textile fabric preparation field, particularly relate to a kind of method for preparing textile fiber with the former retting of environment-friendly type.
Background technology
Bast-fibre is one of important textile raw material of China, and flax fibre is the extract of natural plants, belongs to the green ecological textile fabric.China is one of the abundantest country of hemp resource in the world, and its resource is very abundant, and output is big, and the crudefiber crop kind reaches over one hundred kind, all in weaving different use is arranged.Wherein ramie output accounts for more than 90 percent of Gross World Product, and flax output occupies the second place of the world, and the total amount of fiber crops occupies the first in the world.Because hemp fabric has moisture absorption, heat radiation, nice and cool good characteristic such as well-pressed, more and more be familiar with and favor by the consumer.Linen textile not only on taking, packing, obtain extensively should, and develop into that family expenses are decorated, a plurality of fields such as medical, so the domestic and international market has a high potential.
Producing of traditional flax fibre is the technology of coming unstuck with alkaline process, wherein also will use a certain amount of acid.Constantly there is at present the scheme of on original technology, reforming to propose.As: Chinese patent CN87101264, CN91111330.4, CN94110637.3, CN02139906.9, CN200510018306.0 are on the basis that soda acid comes unstuck, and technology is reformed, having plenty of has increased sonicated, and the difference at numb kind that has changes technology.
The patent that also has is that traditional soda acid technology is come unstuck to fibre of flax for textile material in conjunction with biology enzyme or bacterium.As: CN85103481, CN98111947.6, CN200410040119.8, CN200410064790.6.
Constantly having since 93 years need not acid, alkali, and occurs with the patent of biology enzyme or microbial degumming technology merely.As: CN93115151.1, CN95112564.8, CN02110152.3, CN200410043720.2, CN200510010914.7, CN200510018309.4, CN200510018310.7, these 7 pieces of patents are come unstuck to fibre of flax for textile material with microorganism.Patent CN200310105286.1 and CN200510042924.9, these 2 pieces of patents are that complex enzyme comes unstuck to fibre of flax for textile material.Patent CN94114280.9 and CN01133357.X utilize the natural mushroom in the environment that the fibre of flax for textile material system of macerating is come unstuck.
Also useful pure physical method is handled, and beats and the gas explosion method as machinery.Such patent has CN200410047033.8 and CN200510114926.4.
The method that also has many patents to provide is that acid, alkali are in conjunction with other chemical assistant.As: CN88102614.X, CN88105767.3, CN88106418.1, CN94103650.2, CN200310124145.4.Their purpose is to reduce the consumption of alkali.Wherein the patent No. is the patent of CN94103650.2, though used hydrogen peroxide, also needs to use alkali.
We are in the patent of 200610031004.1 " a kind of method of preparing fiber for weave by peroxide degumming method " at application number, and having delivered need not acid, alkali, and finishes bleaching process when coming unstuck.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly prepares the method for textile fiber with the former retting of environment-friendly type, and practicability and effectiveness is come unstuck, bleached to this method, and the flax fibre that obtains can be used for the processing of all kinds of textiless, the treated discharge standard that promptly reaches of waste water.
Of the present inventionly a kind ofly prepare the method for textile fiber, comprise the following steps: with the former retting of environment-friendly type
(1) be 4 with mass ratio: 1-2: 1 organic solvent and raw ramie, under 60-120 ℃ temperature, kiering 2-5 hour, extract the lignin in the raw ramie;
(2) the organic degumming baths with hydrogen peroxide removes agent as pectin and hemicellulose, and rise to 50-100 ℃ from room temperature half an hour, and the flax fibre after insulation under this temperature was handled delignification in 1-4 hour, obtains the weaving flax fibre.
The former flax fibre of described step (1) is meant ramie, flax, jute or bluish dogbane;
The organic solvent of described step (1) is acetone, butanone, butyl acetate;
The component of organic degumming baths of described step (2) is that the concentration expressed in percentage by weight of hydrogen peroxide is that the concentration expressed in percentage by weight of 5-25%, Sodium Polyacrylate or citric acid or disodium ethylene diamine tetraacetate is that the concentration expressed in percentage by weight of 1-10%, urea is that the concentration expressed in percentage by weight of 1-8%, carboxymethyl cellulose is 1-7%, adds water to percent;
The fiber crops that remove behind the lignin of described step (2) are 1 to the weight ratio of organic degumming baths: 10-1: 20.
The present invention has adopted two step method to produce textile fiber, at first the organic solvent with the solubilized lignin removes lignin earlier, the back is made into the pectin of no inorganic salts and the degumming baths of hemicellulose with the inorganic salts that the organic matter that can be microbial decomposition substitutes in former " a kind of method of preparing fiber for weave by peroxide degumming method " patent, also fiber is bleached when coming unstuck.The inorganic salts that just are not difficult in the waste discharge eliminate that come unstuck of organic degumming baths like this exist, and waste water can directly carry out biochemical treatment at blast pool and reaches the water quality discharge standard like this.Inorganic salts are generally little to the COD influence of water quality in the waste water, but remove very difficulty, can only could effectively remove with technology such as ion-exchange, film infiltration, electrodialysis.Mostly the jute mill does not all deal with inorganic salts in the waste water, but is tangible to the influence of environment obviously.Fiber crops of the present invention are handled waste water through the blast pool biochemical treatment, can reach the discharging of no inorganic salts; And the organic solvent after the organic solvent delignification of the first step can reclaim by distillation, also can obtain senior lignin in addition, and this is not this patent content, and this patent content only is that environmental protection ground obtains the weaving flax fibre.
Characteristics of the present invention be except have application number be 200610031004.1 only with chemical assistant and fully need not acid, alkali, advantage that dosage is few and row yielding improve, outside the advantage of fiber softening, maximum characteristics are to be the method that the retting of environment-friendly type is produced textile fiber fully, do not contain reluctant inorganic salts in the waste water fully, waste water can reach discharge standard through the blast pool biochemical treatment.
