Description
Technical field
The invention belongs to the textile industry field, relate to a kind of high-tenacity calamine alginate fibre, also relate to high-tenacity calamine alginate fibre preparation method and application thereof.
Background technology
The environmental consciousness of Along with people's is constantly strengthened, and 21 century " green garment ", " green consumption " will be dominated world textile article and clothes trend.Main raw material source as modern textile; Fiber such as linen-cotton, petrochemical industry is restricted by resource, Environmental costs more and more; Therefore each state is all exerting to develop biodegradable, integrates nature and attractive in appearance, the comfortable and healthy new fiber species of natural environmental-protective type.
21 century will be again the century of ocean, will get into darker field to the utilization of marine resources.In recent years, alginate fibre had obtained concern because of its various excellent properties in medical field, had obtained using widely in textile industry.
China scientific research personnel, is spun into silk thread and is made into cloth successfully from the extracting algae fiber through research for many years, in the ocean, opens up the 3rd source of textile fabric.At present, producing of alginate fibre gets into preliminary examination and pilot scale stage, produces also in set-up procedure on a large scale.
According to reports: by existing production technology, one ton of limnetic dry kelp can extract 200 kilograms to 250 kilograms alginates, forms 200 kilograms of fibers, and per 100 gram alginate fibres just can be knitted one square metre of cloth.50,000-70,000 yuan per ton of the cost initial estimate of alginate fibre alginate fibre and cotton blending, can be knitted more cloth, and cost is lower, and cotton solid of the cloth strength ratio of processing by alginate fibre.Land fiber and the synthetic fiber limitation aspect environmental protection is more and more outstanding now, is necessary very much to seek a kind of new reproducible environmental protection fiber material.
2010; China consumes the 4130 ten thousand tons of left and right sides fibers year; The production approach is mainly derived from animals and plants natural fabric and regenerated fibers thereof such as cotton, fiber crops, hair, silk; And the synthetic fiber of taking from oil, but along with economic development and population growth, obtaining of fiber more and more receives soil and the short restriction of petroleum resources.Meanwhile, the living beings chemical fibre is just flourish in China, and 2009, China's living beings regenerated fiber production capacity reached 1,910,000 tons, accounts for 77% of world's aggregated capacity.
China is maximum in the world algae culturing and processing state, and alginate output accounts for the over half of the world, is very beneficial for the acquisition and the large-scale development production of alginate fibre raw material.China's seaweed chemical product is very abundant, is the alginate fibre of development of raw materials with the alginate, and the field that obtains fiber has been expanded to the ocean from land, has increased the source of textile fabric.Simultaneously, the production of alginate fibre raw material does not take oil and land resource, owing to take from the ocean, alginate fibre has essential anti-flammability.These advantageous feature of alginate fibre add good textile processibility ability, make it not only can make common clothing, can also be used to make the clothes of specific uses such as fire-entry suit, protective clothing, medical treatment clothes.It is reported that alginate fibre fabric has broad application prospects in fields such as high-grade health-care clothing, toy for children and fire-fighting, medical treatment, military affairs and environmental protection.
Estimate at more than 25000 kind of marine alga in the world ocean, but be four big types of red algae, brown alga, green alga and blue-green algaes by the color rough segmentation.The raw material of alginate fibre are from the algal polysaccharides that is extracted in the natural seaweed.Its organic polysaccharide part is by beta-D-mannuronic acid (β-D-mannuronic acid; Be called for short M) and two kinds of components formations of α-L-guluronic acid (α-L-guluronic acid is called for short G), see figure l, Fig. 2; Nontoxic; Biology can be high with degraded and biologically active, and is good with human compatibility, is suitable as very much medical material.
G unit in the sodium alginate structure can with Ca
2+Form special " egg-box " structure, see Fig. 3, Fig. 4.Utilizing this character of sodium alginate, with the water-soluble formation viscous solution of solubility alginate (using sodium alginate usually), is coagulating bath with hypotoxic calcium chloride (anhydrous), adopts wet spinning technology to prepare alginate fibre.
Since 1980, the alginate fibre gauze is widely used in the west medical profession, and many clinical researches have proved this yarn
The superior function of cloth.But according to bibliographical information, the alginate fibre of producing both at home and abroad at present is harder crisp, and brute force is lower, has limited its range of application, brings certain difficulty to industrialization production.The present invention adopts wet spinning process to prepare powerful higher alginate fibre; Brute force reaches 4.67cN/dtex; And study the various factors that influences its ultimate strength, and obtained the optimum process condition of preparation high-tenacity alginate fibre, simultaneously its structure and performance are studied.There is groove on alginate fibre even thickness and vertical surface with prepared of the present invention, and the cortex that cross section approximate circle shape and nothing are thicker exists, and the vertical and cross section of alginate fibre is seen Fig. 5.Process conditions of the present invention can be large-scale industrial production foundation are provided.
Calamine has very high medicinal and health care and is worth, and the medicinal function of calamine is at multiple successive dynasties medicine ancient books, and is all on the books on the modern drug encyclopedia.Calamine is a crude drug simply: the medicine name: calamine, and English name: luganshi, nature and flavor: sweet flat, return liver, the stomach warp.Main component is zinc carbonate (ZnCO
3), aqueous carbonic acid zinc (ZnCO
3.2Zn (OH)
2.H
2O), zinc oxide (ZnO).The calamine effect: detoxifcation makes eye bright, and removes the screen hygroscopic, and with controlling red eye, swell pain, order is given birth to the screen film, the mashed dizzy eye of wind; Hygroscopic is antipruritic, and regenerating tissue to heal wond is with controlling the wet sore of eczema, unhealing ulcer.The clinical treatment that can be used for multiple contact dermatitis, skin disorder, in particular for unhealing ulcer, pus is dripping, wet sore, skin is disturbed treatment of conditions such as itch.
High-tenacity alginate fibre textiles is combined with calamine medicinal health function, and high-tenacity calamine alginate fibre except that medical, the medical advantage with high-tenacity and alginate fibre, also gives the high-tenacity alginate fibre medicinal and health care.High-tenacity calamine alginate fibre has multiple physiologically active, helps to strengthen cell viability, can play conditioning skin, body beautification health effect; And high-tenacity calamine alginate fibre also has significant anti-ultraviolet property, and all there is shielding action in UVA district and the ultraviolet ray of UVB district; Visible light transmissivity is big; Also have good antibacterial performance in addition, therefore, high-tenacity calamine alginate fibre is the desirable green algae fiber with Chinese medicine function.
Although high-tenacity alginate fibre and calamine differ from one another,, still unmanned with alginate fibre and calamine combination up to now, make a kind of product have the advantage of two kinds of materials simultaneously.The inventor studies after understanding, grasping the characteristic of high-tenacity alginate fibre and calamine through great efforts, and the health care with high-tenacity alginate fibre textiles and calamine combines finally, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of high-tenacity calamine alginate fibre, it is not only powerful high but also have the advantage of medical, the medicinal properties of alginate fibre, gives new medicinal and health care simultaneously again, improves material quality.
