玉米纤维?聚乳酸纤维(PLA)
淄博蛋白纤维纺织品科技开发有限公司·淄博普尔迪纺织品销售有限公司敬示:
生产原料乳酸是从玉米淀粉制得,故也称为玉米纤维,PLA纤维是在美国***的谷物公司Cargill公司研制成功的玉米聚乳酸树脂的基础上,在1997年该公司和美国Dow Polymers公司合股成立了 Cargill Dow Polymers公司,全力发展了聚乳酸原料,到2002年聚乳酸年产已达14万吨,生产的PLA纤维商品名为Ingeo。日本钟纺、尤尼契卡和可乐丽公司生产的PLA纤维商品分别为Lactron、Terramac和 Plastarch,美国杜邦公司和孟山都等公司也开始开发PLA纤维。目前,商业化生产的PLA纤维是以玉米淀粉发酵制成乳酸,经脱水聚合反应制得聚乳酸酯溶液进行纺丝加工而成。PLA纤维之所以受到众多纤维公司和消费者关注,并显示强大的生命力,主要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***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、***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;

Lactic acid production material from corn starch process. The reason also known as corn fiber, PLA fiber is the famous American grain company in the successful development of the corn Cargill company polylactic acid resin, and on the basis of the company in 1997 and the Dow Polymers company established partnership Cargill Dow Polymers company, to the development of polylactic acid raw materials, to 2002 years of polylactic acid has reached 140000 tons, the production of PLA fiber goods Ingeo called. Japan clock spinning, especially QiKa and coke, li company produces the PLA fiber goods were Lactron, Terramac and Plastarch, American dupont and companies such as monsanto also begin to develop PLA fiber. At present, the commercial production of the PLA fiber is made from corn starch ferment lactic acid, the dehydration of polymerization polylactic acid ester solution spinning processing and into. The PLA fiber by numerous fiber company and consumer attention, and show strong vitality, the main 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 across;
(3) modulus and bending stiffness is polyester half, so soft;
(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 ultraviolet prevention ability, ultraviolet absorption rate is low;
(7) refractive index is low, the dyeing products good color rendering;
