人造棉是什么成分,所谓的化学化纤是不是塑料的一种,是那一种呢,

棉线应该是多糖,烧了以后成灰了,没什么味道
羊毛线是蛋白质,烧了以后也是灰,有烧焦羽毛的味道
合成纤维一烧就卷起来了,有刺激性气味

In this paper,Viscose fiber is also called artificial cotton, is a kind of regenerated cellulose fiber, natural fiber as raw materials by wet spinning, with skin core layer structure, active cui LAN structure because of its special copper phthalocyanine dyes, lead to dye molecules diffusion within the fiber is more difficult, withering printed fabric color light and color. So it is difficult to dye diffusion penetration, printing need a lot of urea to hygroscopic help dissolve, help dissolve dye. As the earth's environmental protection consciousness enhancement, as a result, water pollution, eutrophication of material namely, nitrogen and phosphorus compounds, to reduce their consumption have become the subjects of dyeing and finishing industry. This article on how to reduce artificial cotton reactive cui LAN K - the amount of urea in the GL dye printing process to explore.
Keywords: viscose/active cui LAN K - GL/urea/environmental protection

Viscose fiber is also called artificial cotton, is a kind of regenerated cellulose fiber, natural cellulose as raw material by wet spinning and made, with skin core structure, because of its excellent properties, widely used in dyeing and finishing industry, especially active in the printing process, the products are deeply welcomed by consumers. While the reactive turquoise blue dye due to its special copper phthalocyanine dye molecule structure, makes more difficult diffusion into the fiber, light and color printing fabric wilt. So the stamp is needed when the amounts of urea to moisture to help dissolve, help dye dissolution. Urea containing nitrogen rich, in recent years, with the improvement of people's consciousness of environmental protection of the earth, as causing water pollution (eutrophication) material, namely the nitrogen, the phosphorus compounds, reduce its consumption has become an important research topic in the dyeing and finishing industry. At the same time, the traditional printing methods using steam fixation, because when steaming water supply, the demand for auxiliaries is not high, we can achieve the dyeing effect is good. But the steam fixation requires a very long time, usually for half an hour, energy consumption is very large. In the current global resource shortage situation, everyone started, as far as possible to reduce energy consumption, saving resources, to the enterprise sustainable development from personal road, the new direction is the development of printing and dyeing industry. So this paper is how to reduce urea reactive turquoise blue K-GL dye printing process of artificial cotton in the amount of exploration, printing methods curing fixation, shorter fixation time (30min → 130s), reducing energy consumption, saving resources. In the experiment we will look for a series of environmental protection urea alternative or adjuvant, to add to the printing paste, while the corresponding reduction in the amount of urea, printing effect is different, to find the best formula is printing effect, we explore the purpose.

区别很大,人造棉烧的时候有刺鼻的化学物质燃烧的味道；x0d而棉燃烧是没有味道的；再,灰烬也不同.棉的灰烬是碎的灰,x0d而人造棉是硬的渣.

① 人造纤维：是化学纤维中最大生产的品种,它是利用有纤维素或蛋白质的天然高分子物质如木材、蔗渣、芦苇、大豆、乳酪等为原料,经化学和机械加工而成.例如：人造棉、人造丝、人造毛、虎木棉、富强棉.
② 合成纤维：合成纤维是化学纤维中的一大类,它是采用石油化工工业和炼焦工业中的副产品.例如：涤纶、锦纶、睛纶、维纶、丙纶、氯纶等都属于合成纤维.
人造棉,也叫粘胶VISCOSE,属于人造纤维素纤维

把植物秸秆、棉绒等富含纤维素的物质,经过氢氧化钠和二硫化碳等处理后,得到的一种纤维状物质,就是黏胶纤维.黏胶纤维中的长纤维俗称人造丝,短纤维俗称人造棉,都可供纺织之用.人造的材料,是人工改造的意思,不属于合成的范畴.

rayon只能指人造丝,纤维,而此处是人造棉针织

区别很大,人造棉烧的时候有刺鼻的化学物质燃烧的味道；
而棉燃烧是没有味道的；再,灰烬也不同.棉的灰烬是碎的灰,
而人造棉是硬的渣.

1,粘胶纤维用的棉不是我们长用的棉花,而是棉花剥棉之后剩在棉花籽上的一层很短的几乎没有利用价值的棉短绒,还有用木纤维,草本纤维之类的东西的,这样就提高是棉的利用率.
2,高配棉,一般是纯棉.就是配棉等级高,这样生产的纱线质量好!
　　高配棉 是普梳中质量比较好一点的.高配棉,无结头纱.
　　比半精梳差点,强力高,做经纱、纬纱均可.
3,全精梳棉就是棉线经过筛选后留下的较长而且整齐的纤维,
精梳和普梳相比,精梳的棉纱更光滑,平整,出来的面料表面平整,没有棉结.
半精梳棉就是没经过烧毛的精梳棉,分辨方法就是侧面看,半精的表面上的小绒毛比全精的要长而杂.
精梳和普梳较好分辨,两者一对比,高下立判
4,丝光棉 乃指经丝光处理(碱处理)的棉纱 .它较为处理者显得更亮(棉表面鳞片被碱融熔而光滑)且有效浆杂质含量减到最低 所以上色均匀 表面略带柔光 手感也柔软
5,二者燃烧的现象差不多,只是粘胶燃烧更快,用燃烧鉴定两者不太好分辨.
6,这个我不懂,是没作过布.

两者成分都是粘胶人造丝是粘胶长丝人造棉是粘胶短纤粘胶纤维是以自然界的木材、芦苇、棉短绒等纤维素为原料,经化学加工制成的.粘胶纤维分长丝和短纤维两种.粘胶长丝又称人造丝或粘胶丝；而粘胶短纤维有棉型的（又称人造棉）、毛型的（称人造毛）及中长纤维.另外,粘胶纤维还可制成有光、半光和消光三种.粘胶纤维属再生纤维素纤维.它是以天然纤维素为原料,经碱化、老化、黄化等工序制成可溶性纤维素黄酸酯,再溶于稀碱液制成粘胶,经湿法纺丝而制成.采用不同的原料和纺丝工艺,可以分别得到普通粘胶纤维,高湿模量粘胶纤维和高强力粘胶纤维等.普通粘胶纤维具有一般的物理机械性能和化学性能,又分棉型、毛型和长丝型,俗称人造棉、人造毛和人造丝.高湿模量粘胶纤维具有较高的聚合度、强力和湿模量.这种纤维在湿态下单位线密度每特可承受22.0cN的负荷,且在此负荷下的湿伸长率不超过15%,主要有富强纤维.高强力粘胶纤维具有较高的强力和耐疲劳性能.

ayon 是人造纤维.
现在rayon通常都是指粘胶纤维
短纤或中长纤叫人造棉（棉纤维就属于短纤）
长纤的rayon通常叫人造丝.
