1、 Asbestos. The chemical fiber includes regeneration fiber, synthetic fiber and inorganic fiber. A Regeneration fiber, for instance: Viscose fiber, acetate fiber. B Synthetic fiber, for instance: Nylon/Polyamide, Polyester, Spandex - /elastic/strec/lycra, Ammonia black silk ribbon, polyvinyl alcohol
2、fiber, polypropylene, Fiber, etc. C Inorganic fiber, for instance: Glass fiber, metallic fibered. 4, the textile performance of the common dope-dyed fiber: Wool:Pick up the moisture, elasticity , take performance to be fine , able to bear , damage by worms , not right to combine the dyestuffs with t
3、he metal while being acid. Silk: Hygroscopic, ventilative, gloss and take of good performance, applicable and acid and direct dyes. Cotton: Ventilative and picking up the moisture, take of good performance, be able to bear being damaged by worms, reduced even nitrogen, alkaline media, sulfide, react
4、ive dyestuffs. Viscose fiber: Hygroscopicity, getting ventilative and fine, color bright, raw material sources wide with low costs, properties are close to natural fiber, applicable dyestuffs the same as cotton. Dacron: Fabric, very comfortable, protecting shape kind, wear-resisting, size steady, ea
5、sy to wash and quick-drying, applicable to disperset dyestuffs, heavy nitrogen disperses Wearability fiber: Polyamide reduces dyestuffs. solubility and dyestuffs very good, ventilative differences, applicable to acid dyes and distribute dyestuffs. Fine black silk ribbon: It is good to be fluffly and
6、 having fur senses, disperse dyestuffs and cationic dyestuffs applicably. The milk textile fiber use the protein which separates by the milk as the basic raw material, results in the regenerated protein fiber after chemistry processing and the machine-finishing system. The protein in the milk the re
7、ason that can become the fiber, because it has the fiber high polymer basic condition: (1) the macromolecule is linear. The protein macromolecule has two kinds: One is the chain shape, namely linear, calls fibrin; another is spherical, calls globulin. The protein in the milk is the casein, which is
8、a striation, it can become the fiber; but the hemoglobin is a globulin, and then cannot become the fiber. (2) Has the certain flexibility and the intermolecular force. The protein mainly composed by the carbon, the oxygen, the hydrogen, the nitrogen, the sulfur, in some protein also contains phospho
9、rus, iron and so on, such as the casein includes phosphorus element. After ultimate analysis, in dry protein the element content for (%): H6.07.0, C5055, O2030, N1517, S0.32.5. From 19 centurys ends, at the beginning of 20th century the foreign courtiers namely have started to research the regenerat
10、ed protein fiber. In 1935 the Italian scientists, in 1938 English ICI Corporation, in 1939 Corn Product Refining Corporation once separately discussed to withdraw the protein from the cows milk, the peanut protein, the corn, the soybean bean cake, then carried on the spinning. In the early 1940s, Am
11、erica, England have developed the labara; In 1945 America, England have studied the Soya protein textile fiber; In 1948 the US General Motors has withdrawn the Soya protein textile fiber from the bean cake, but mostly because the textile fiber performance is poor, which unable to carry on the textil
12、e processing but to sever the research. Recently a Japanese textile company developed the milk protein textile fiber has realized the industrialization production, because 100 kilograms milks only could withdraw two kilograms protein, caused the was stability fiber thermal textile also the high, exc
13、essively cost production bad, Above120 dry heat is easy to have the e yellow spot, the force dropped, therefore it still unable massively to promote the use until now. In August, 2000.One day, Li Guanqi accompaned with Suzhou University professors Wang Huas to bring the soybean egg albumin fiber whi
14、ch through ten years painstaking care develops, entered the national spinning and weaving industry bureau for the first time. Until now, only more than two years. if lets us turn the head these two years trail, during that time we can discover the original national spinning and weaving industry bure
15、au, presently the China textile industry association for the soybean egg albumin fiber promotion and application directly organised,coordinated, participated big scale seminar, the training class, the press conference, the appraisal conference and so on, each kind of activity unexpectedly reaches te
16、n above time. At present participated in the soybean egg albumin fiber the product development textile enterprise, the universities, colleges and institutes, the scientific research institute already reaches above hundred, the product development scope has involved to each domain, such as the cotton
17、 and kapok, the wool, the hemp, the silk, the knitting, printing, all of theseprotectedand moistened the growth of the soybean egg albumin fiber in the industrial weak time. Invented by Li Guanqi develops the successful soybean egg albumin fiber to rewrite China in the application textile fiber doma
18、in original creative technology for the zero record, after hundred and thousand of engineers and technicians, the experts participated in the research of the soybean egg albumin fiber the product development and the correlation craft technology breakthrough will certainly bring the bright prospect f
19、or the soybean egg albumin fiber industrial production, the commercialization. The soybean egg albumin fiber use the bean cake which fries in oil and the soybean leaching as the raw material, the use bio-engineering new technology, withdraws purely the bean cake in globulin, through helps the medici
20、nal preparation, the biological enzyme function, causes the depuration the and hydroxyl the structure, then increases spatial change globulin the cyano high polymer, compounds the certain density of the protein spinning fluid, after the ripening, creates he green textile fiber with the aqueous metho
21、d spinning system, it both has the fine performance of the natural silk , and has the machine capability of the synthetic fiber , also has satisfied the pursue of the people to comfortableness and the artistic, also conforms the tidal current to the clothing exempt burns and may wash which puts on.
22、The affinity is good between soybean egg albumin fiber and human body, also includes the human body to have the amino acid, joined the quota remarkably in the spinning craft the sterilization sterilization Chinese herb, the drug efficacy is lasting, has raised the underwear effect tide. In this pape
23、r the optimal design of spline (or key) profiles for three different design criteria is presented. The method of calculus of variation is used to determine profile functions for maximum value. Analytical results are successfully obtained. It shows that the splines with involute profiles lead to unif
24、orm deformation on the hub, in addition they can carry the maximum transmission load capacity. On the other hand radial straight profiles result in optimum transmission efficiency. We believe similar approach could be used to determine other spline profiles when new performance criteria are imposed.

27、工制得的再生蛋白质纤维。牛奶中蛋白质之所以能成纤,是因为它具备成纤高聚物的基本条件:大分子是线型的。蛋白质大分子有两种:一种是链状的,即线型的,称之为纤维蛋白;另一种是球状的,称之为球蛋白。奶中蛋白即酪蛋白是线状的,可以成纤;而血红蛋白是球蛋白,则不能成纤。具有一定的柔性和分子间力。蛋白质主要是由碳、氧、氢、氮、硫5种元素组成,某些蛋白质中还含磷、铁等元素,酪蛋白中即含有磷元素。经元素分析,干燥蛋白质中元素含量为(%):H6.07.0、C5055、O2030、N1517、S0.32.5。国外从19世纪末、20世纪初即开始对再生蛋白质纤维进行研究。1935年意大利科学家、1938年英国ICI公司
28、、1939年Corn Product Refining公司曾分别探讨从牛乳、花生蛋白质、玉米、大豆豆粕中提取蛋白质,再进行纺丝。20世纪40年代初,美、年美国通用汽车1948年美、英又研究了大豆蛋白质纤维;1945英研制了酪素纤维;公司从豆粕中提取了大豆蛋白质纤维,但大多因为纤维性能较差,无法进行纺织加工而中断研究。近年日本东洋纺公司开发的牛奶蛋白质纤维实现了工业化生产,由于100公斤牛奶只能提取两公斤蛋白质,使得制造成本过高,且纤维耐热性差,在干热120以上时易泛黄,强力下降,因此至今仍无法大量推广使用。2000年8月某日,李官奇在苏州大学教授王华杰的陪同带着他历经十年心血研制成的大豆蛋白纤
