Compared with cotton , vinylon has stronger tenacity and elongation , better abrasive resistance , stronger hygroscopicity , and better heat preservation , and it has better resistance to chemical corrosion , sunlight , moth , mold , and radiation as well . vinylon can be spun with cotton or other fibers into knitting goods and other cloth . it is also used as industrial fiber for the manufacture of tire cord , conveyer , fire hose , fish net , ropes , canvas , filter cloth , and rubber items etc 维尼纶是以聚乙烯醇为原料纺成的合成纤维，其性能与棉花相似，与棉花相比又有强伸度大耐磨性好吸湿性强的优点和更好的耐化学腐蚀性耐晒性耐蛀霉性保暖性及耐辐射性等，可与棉花及其它纤维混纺以织造针织物及其它用布，同时作为工业用纤维，广泛用于制造轮胎帘子线运输带水带鱼网绳索帆布过滤布及橡胶制品等。
The vinylon staple linear density 1 . 56dtex , length 35mm produced by the company was awarded excellent product by fujian provincial government and the ministry of textile industry of china . the company can also supply different specifications of spool yarn , ultra short staple , water soluble fiber , medium length fiber , colored fiber , fiber of medium strength and modulus , and fiber of high strength and modulus to meet the demands of the customers 我公司生产的维尼纶短纤产品质量上乘，曾获得省优部优称号，同时我公司还可根据用户需要提供各种规格的维尼纶卷筒丝超短纤水溶性纤维中长纤维有色纤维及中强中模纤维高强高模纤维等系列产品，欢迎广大用户选用。
According to the observed experiments that the na2feo4 solution with the same concentration and volume were decomposed by the same area of different membrane , we learned the order of the decomposing rate of na2feo4 caused by different membranes : soapnated cellulose acetate > vinylon > polypropylene polyvinyl chloride = polyethylene microfiber glass mat 从观察等面积的隔膜引起同浓度同体积的na _ 2feo _ 4溶液的分解实验可知，不同隔膜材料引起na _ 2feo _ 4溶液分解速率从大到小的顺序是，皂化再生纤维素膜维尼纶无纺布改性聚丙烯膜聚氯乙烯膜辐射接枝聚乙烯膜复合玻璃纤维毡。
When they were respectively used as separator in zn / k2feo4 battery , the percent of capacity of the cathode active material na2feo4 were : microfiber glass mat ' s : 93 % ; polyethylene ' s : 68 % ; polypropylene ' s : 56 % ; polyvinyl chloride ' s : 47 % ; vinylon ' s : 38 % ; soapnated cellulose acetate ' s : 24 % . although five of them ( not concluding soapnated cellulose acetate ) had very weak or weaker reductivity as separator in super - iron battery , for which th ey were more suitable to being separator in super - iron battery 作为隔膜用于zn k _ 2feo _ 4实验电池，正极活性物质k _ 2feo _ 4的放电容量效率分别为复合玻璃纤维膜93 、辐射接枝聚乙烯膜68 、改性聚丙烯微孔膜56 、聚氯乙烯微孔膜47 、维尼纶无纺布38 、皂化再生纤维素膜24 。
The fitness of four negative electrode materials such as al , fe , zn , cd , and of six membranes materials : microfiber glass mat separator , polyethylene , polypropylene , polyvinyl chloride , vinylon , soapnated cellulose acetate , and of four current collects : carbon fiber ; nickel foam ; nickel foam sthongthened by iron wire net , punched silver grid in the super - iron alkaline batteries was comparatively studied . the influence of two storaged method ( with and without electrolyte ) and two impurities ( zno , fe ( oh ) 3 ) to the experiment cell ' s self - discharge nature was also comparatively studied . at last , the nature of discharge . structure and electrochemistry of experimental cell with k2feo4 as cathode active material prepared by three different methods : high temperature reaction , hypochlorite oxidizing and electrolysis , was comparative ly studied . we can conclude : i ) the open - circuit potential and the flat of work potential and the percent of capacity of k2feo4 till 1 . 0v during the discharge at constant load of experimental cells decreased by the order of al / k2feo4 , zn / k2feo4 , cd / k2feo4 , fe / k2feo4 . as for the nature of charge - discharge cycle , cd / k2feo4 fe / k2feo4 zn / k2feo4 . in water solute electrolyte , although al / k2feo4 can n ' t be used as storage battery , it have great potential as primary cell or storage cell from the aspect of its discharge capacity . discharge power 采用组装实验电池、 x -射线衍射( xrd )和循环伏安( cv )的方法，从实验电池的放电特性、充放电循环特性、自放电特性，不同高铁酸盐的结构特性和电化学特性几个方面，对4种金属负极材料( al 、 fe 、 zn 、 cd ) 、 6种隔膜材料(复合玻璃纤维、幅射接枝聚乙烯、改性聚丙烯、聚氯乙烯、维尼纶无纺布、皂化再生纤维素) 、 4种集流体材料(泡沫镍、以铁网为加强层的泡沫镍、切拉银网、炭纤维编织网)在碱性高铁电池中的适用性进行了比较研究；对2种杂质组分( zno 、 fe ( oh ) _ 3 )和2类不同贮存方式(干、湿)对实验电池自放电特性的影响进行了比较研究；对3种方法(高温固相反应、次氯酸盐氧化、直流电解)所制k _ 2feo _ 4的实验电池的放电特性、结构特性和电化学性能进行了比较研究。
