 人造纖維的短纖維一律叫“纖”（如、富纖），合成纖維的短纖維一律叫“綸”（如錦綸、滌綸）。如果是長(zhǎng)纖維，就在名稱末尾加“絲”或“長(zhǎng)絲”（如粘膠絲、、腈綸長(zhǎng)絲）。

隨著全球化纖生產(chǎn)進(jìn)一步向中國(guó)轉(zhuǎn)移，中國(guó)已經(jīng)成為世界最大的化纖生產(chǎn)國(guó)。中國(guó)化纖產(chǎn)量占據(jù)全球總量的60%以上。我國(guó)化纖工業(yè)持續(xù)快速發(fā)展，明顯提高，全面完成了規(guī)劃的各項(xiàng)目標(biāo)任務(wù)，有力推動(dòng)和支撐了紡織工業(yè)和相關(guān)產(chǎn)業(yè)的發(fā)展，在世界化纖產(chǎn)業(yè)中的地位與作用進(jìn)一步提升。

2012年，我國(guó)化纖產(chǎn)量累計(jì)為3876.2萬(wàn)噸，同比增加500.2萬(wàn)噸，增長(zhǎng)14.82%�；w及其制品已經(jīng)形成完整的產(chǎn)業(yè)配套基礎(chǔ)，國(guó)際市場(chǎng)競(jìng)爭(zhēng)優(yōu)勢(shì)明顯。

2013年，我國(guó)化纖行業(yè)實(shí)現(xiàn)利潤(rùn)總額259.8億元，同比增長(zhǎng)18.3%。行為3.6%，比2012年提高0.3個(gè)百分點(diǎn)。2013年化纖產(chǎn)量繼續(xù)保持增長(zhǎng)，全年共完成產(chǎn)量4122萬(wàn)噸，同比增長(zhǎng)7.9%。其中，滌綸3341萬(wàn)噸，同比增長(zhǎng)6.6%，增速下降了2.8個(gè)百分點(diǎn)；氨綸產(chǎn)量增長(zhǎng)最快，增速達(dá)27.3%。2014年化纖行業(yè)利潤(rùn)總額277.30億元，同比增長(zhǎng)6.7%。2012-2014年利潤(rùn)總額持續(xù)增長(zhǎng)。2014年化纖行業(yè)10.06%。2010-2014年我國(guó)化纖行業(yè)毛利率增長(zhǎng)較平穩(wěn)，起伏波動(dòng)較小。

據(jù)中國(guó)產(chǎn)業(yè)調(diào)研網(wǎng)發(fā)布的中國(guó)化纖行業(yè)現(xiàn)狀調(diào)研及未來發(fā)展趨勢(shì)分析報(bào)告（2016-2020）顯示，“十三五”期間，隨著世界經(jīng)濟(jì)的復(fù)蘇和發(fā)展，在國(guó)際紡織品服裝市場(chǎng)需求繼續(xù)保持增長(zhǎng)趨勢(shì)的帶動(dòng)下，化纖工業(yè)作為紡織品服裝的原料產(chǎn)業(yè)也將繼續(xù)保持增長(zhǎng)態(tài)勢(shì)，我國(guó)化纖及其制品憑借較為明顯的國(guó)際競(jìng)爭(zhēng)優(yōu)勢(shì)，國(guó)際市場(chǎng)還有繼續(xù)擴(kuò)大的空間。

同時(shí)，隨著國(guó)內(nèi)人民生活水平進(jìn)一步改善和進(jìn)程的加快推進(jìn)，也將直接拉動(dòng)化纖產(chǎn)品消費(fèi)的增加。由此可見，未來我國(guó)化纖行業(yè)前景依然看好

化學(xué)纖維的制備，通常是先把天然的或合成的高分子物質(zhì)制成紡絲熔體或溶液，然后經(jīng)過過濾、計(jì)量，由板）擠出成為液態(tài)細(xì)流，接著凝固而成纖維。此時(shí)的纖維稱為初生纖維，它的力學(xué)性能很差，必須經(jīng)過一系列后加工工序才能符合紡織加工和使用要求。后加工主要針對(duì)纖維進(jìn)行拉，以提高纖維的力學(xué)性能。拉伸是使初生纖維中大分子或結(jié)構(gòu)單元沿著纖維軸取向；熱定形主要是使纖維弛。濕紡纖維的后加工還包括水洗、上油、干燥等工序。紡制長(zhǎng)絲時(shí)，經(jīng)上述工序即可卷繞成筒；紡制短纖維時(shí)還須增加卷曲、切斷和打包等工序。用來生產(chǎn)紡織品的原料中，以棉、麻、絲、毛（羊毛）的歷史最悠久。但是天然資源畢竟有限，棉花的產(chǎn)量約有50千克/公頃，養(yǎng)蠶吐絲也要種桑樹，增產(chǎn)羊毛則要發(fā)展畜牧業(yè)。因此，化學(xué)家開始研究，利用價(jià)格更便宜、來源更豐富的原料來紡紗織布，它們便是化學(xué)纖維。

The short fiber of man-made fiber is called "fiber" (be like, rich fiber), the short fiber of synthetic fiber is called "fiber" (be like polyamide, dacron).For long fibers, add "silk" or "filament" (such as viscose, acrylic, etc.) at the end of the name.

China has become the world's largest producer of chemical fiber as global production shifts further to China.China produces more than 60% of the world's chemical fibre., the rapid development of chemical fiber industry in China has improved significantly, complete the objectives of the planning task, vigorously promote and support the development of the textile industry and related industries, to further improve the position and role of the chemical fiber industry in the world.

In 2012, China's chemical fiber output totaled 387.62 million tons, an increase of 5 million to 12 million tons over the same period last year, an increase of 14.82 percent.Chemical fiber and its products have formed a complete industrial supporting basis, the international market competitive advantage is obvious.

In 2013, China's chemical fiber industry realized a total profit of 25.98 billion yuan, up 18.3% year on year.Behavior was 3.6%, up 0.3 percentage points from 2012.In 2013, chemical fiber production continued to grow, with a total output of 41.22 million tons in the whole year, up 7.9 percent year on year.Among them, dacron 33.41 million tons, up 6.6 percent year on year, down 2.8 percent growth rate;Spandex production grew the fastest, up 27.3%.In 2014, the total profit of chemical fiber industry was 27.73 billion yuan, up 6.7% year on year.The total profit continued to increase from 2012 to 2014.2014 chemical fiber industry 10.06%.From 2010 to 2014, the gross profit rate of China's chemical fiber industry increased steadily with less fluctuation.

According to the release of China's chemical fiber industry of China industry research network research present situation and future development trend analysis report (2016-2020), according to "much starker choices-and graver consequences-in" period, as the world economic recovery and development, in the continued growth of the international textile clothing market demand trend leads, the chemical fiber industry as raw materials of textile clothing industry will continue to maintain growth, China's chemical fiber and its products with the evident in the international competition advantage, and continue to expand the international market space.

At the same time, with the further improvement of domestic people's living standards and the acceleration of the progress, it will also directly promote the increase of chemical fiber product consumption.Therefore, the future of China's chemical fiber industry is still promising

Chemical fiber preparation, is usually the first natural or synthetic polymer material spinning melt or solution, and then filtered, metering, extrusion to trickle, liquid by plate) and then frozen fibers.At this time, the fiber is called primary fiber, its mechanical properties are very poor, it must go through a series of post-processing procedures to meet the textile processing and use requirements.The post-processing is mainly aimed at fiber pulling to improve the mechanical properties of fiber.Stretching is the orientation of large molecular or structural elements along the fiber axis in primary fibers.The thermosetting is mainly to relax the fiber.The post-processing of wet spinning fiber also includes washing, oiling and drying.When spinning the filament, it can be wound into a tube through the above procedure.The winding, cutting and packing of short fiber should be added.Among the raw materials used in the production of textiles, cotton, hemp, silk and wool have the longest history.However, the natural resources are limited after all. The yield of cotton is about 50kg/ha.So chemists began to study the use of cheaper, more abundant materials for spinning fabrics called chemical fibers.
