聚乳酸?玉米纖維 淄博蛋白纖維紡織品科技開發(fā)有限公司?淄博普而迪紡織品銷售有限公司：玉米纖維Corn Fiber(聚乳酸纖維，PLA纖維) 　　是以玉米淀粉為原料，經(jīng)發(fā)酵轉(zhuǎn)化成乳酸再經(jīng)聚合，紡絲而制成的合成纖維。 　　此纖維具有生物可降解性，玉米纖維輕柔滑順，強(qiáng)度大，吸濕透氣，加工的產(chǎn)品有絲綢般的光澤及舒適的肌膚觸感和手感，懸垂性佳，良好的耐熱性及抗紫外線功能，服用性能好。 　　PLA纖維是以淀粉制得之乳酸為原料，屬于完成自然循環(huán)型，具有生物降解性的纖維。該纖維完全不使用石油等化工原料，其廢棄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，不會(huì)污染地球環(huán)境。由于該纖維的初始原料為淀粉，其再生之循環(huán)周期短，大約為一至二年，其產(chǎn)生的二氧化碳可由植物光合作用減少在大氣中的含量。燃燒PLA纖維，幾乎沒有一氧化氮，其燃燒熱是聚乙烯和聚丙烯的三分之一左右。 聚乳酸纖維是以人體內(nèi)含有的乳酸作原料合成的乳酸聚合物，對人體而言是**安全的。經(jīng)測試，以玉米纖維制成的圓形針織布不會(huì)刺激皮膚，且對人體健康有益，并有舒適感。PLA纖維有許多突出的優(yōu)點(diǎn)： （1）原料來自于天然植物，容易生物降解，降解產(chǎn)物是乳酸、二氧化碳和水，是新一代環(huán)保型可降解聚酯纖維。 （2）有較好的親水性、毛細(xì)管效應(yīng)和水的擴(kuò)散性； （3）模量和彎曲剛度是滌綸一半，故手感柔軟； （4）有良好的回彈性、抗皺性和保形性； （5）限氧指數(shù)較高（L0I 24-29），點(diǎn)燃后自熄性好、燃燒發(fā)煙量低，有較好阻燃性； （6）有防紫外線能力，紫外線吸收率低； （7）折射率低、染色制品顯色性好；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;
