聚乳酸?玉米纤维 淄博蛋白纤维纺织品科技开发有限公司?淄博普而迪纺织品销售有限公司：玉米纤维Corn Fiber(聚乳酸纤维，PLA纤维) 是以玉米淀粉为原料，经发酵转化成乳酸再经聚合，纺丝而制成的合成纤维。 此纤维具有生物可降解性，玉米纤维轻柔滑顺，强度大，吸湿透气，加工的产品有丝绸般的光泽及舒适的肌肤触感和手感，悬垂性佳，良好的耐热性及抗紫外线功能，服用性能好。 PLA纤维是以淀粉制得之乳酸为原料，属于完成自然循环型，具有生物降解性的纤维。该纤维完全不使用石油等化工原料，其废弃物在土壤和海水中的微生物作用下，可分解成二氧化碳和水，不会污染地球环境。由于该纤维的初始原料为淀粉，其再生之循环周期短，大约为一至二年，其产生的二氧化碳可由植物光合作用减少在大气中的含量。燃烧PLA纤维，几乎没有一氧化氮，其燃烧热是聚乙烯和聚丙烯的三分之一左右。 聚乳酸纤维是以人体内含有的乳酸作原料合成的乳酸聚合物，对人体而言是**安全的。经测试，以玉米纤维制成的圆形针织布不会刺激皮肤，且对人体健康有益，并有舒适感。PLA纤维有许多突出的优点： （1）原料来自于天然植物，容易生物降解，降解产物是乳酸、二氧化碳和水，是新一代环保型可降解聚酯纤维。 （2）有较好的亲水性、毛细管效应和水的扩散性； （3）模量和弯曲刚度是涤纶一半，故手感柔软； （4）有良好的回弹性、抗皱性和保形性； （5）限氧指数较高（L0I 24-29），点燃后自熄性好、燃烧发烟量低，有较好阻燃性； （6）有防紫外线能力，紫外线吸收率低； （7）折射率低、染色制品显色性好；Corn Fiber Corn Fiber (poly lactic acid Fiber, PLA Fiber) Corn starch as raw material, is by fermentation into lactic acid polymerization, spinning and is it made of synthetic fiber. The fiber has biodegradable sex, corn fiber, the soft and light intensity big, wet absorption, processing of the products have gas the burnish like silk and comfortable skin tactility, drapability and feel good, good heat resistance and ultraviolet function, take good performance. PLA fiber is of starch of lactic acid as raw materials, to complete natural circular, has the biodegradation of fiber. The fiber doesn't use oil, and other chemical raw materials, its waste in soil and water, the microbes may be broken down into carbon dioxide and water, not polluting the earth environment. Because the fiber of raw materials for the starch, the initial regeneration cycle, about the short for one to two years, the production of carbon dioxide from the plant photosynthesis can reduce the content in the atmosphere. Burning PLA fiber, almost no nitric oxide, its burning hot is about a third of polypropylene and polyethylene. Poly lactic acid fiber is the human body contains some lactic acid as raw materials of lactic acid polymer synthesis, for our bodies are absolutely safe. The test to corn fiber round knitting won't stimulate the skin, and beneficial to human body health, and comfort. PLA fiber has many outstanding qualities: (1) raw material from natural plants, easily biodegradable, degradation products is lactic acid, carbon dioxide and water, is a new generation of environmental protection biodegradable polyester fiber. (2) good hydrophilic, capillary effect and water of avian; (3) modulus and bending stiffness is polyester, so soft half; (4) good recovery, wrinkle resistance and the form sex; (5) limit the oxygen index is higher (L0I 24-29), lit self-extinguishing RTV silicone compound good, burning hair smoke is low, and have a good flame retardancy; (6) have uv ultraviolet absorption rate is low; ability, (7) refractive index is low, the dyeing products show color the gender is good;
