隨著全球化纖生產(chǎn)進(jìn)一步向中國轉(zhuǎn)移，中國已經(jīng)成為相當(dāng)大的化纖生產(chǎn)國。中國化纖產(chǎn)量占據(jù)全球總量的60%以上。我國化纖工業(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，在化纖產(chǎn)業(yè)中的地位與作用進(jìn)一步提升。

2012年，我國化纖產(chǎn)量累計(jì)為3876.2萬噸，同比增加500.2萬噸，增長14.82%。化纖及其制品已經(jīng)形成完整的產(chǎn)業(yè)配套基礎(chǔ)，國際市場(chǎng)競(jìng)爭(zhēng)優(yōu)勢(shì)明顯。

2013年，我國化纖行業(yè)實(shí)現(xiàn)利潤總額259.8億元，同比增長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，全年共完成產(chǎn)量4122萬噸，同比增長7.9%。其中，滌綸3341萬噸，同比增長6.6%，增速下降了2.8個(gè)百分點(diǎn)；氨綸產(chǎn)量增長很快，增速達(dá)27.3%。2014年化纖行業(yè)利潤總額277.30億元，同比增長6.7%。2012-2014年利潤總額持續(xù)增長。2014年化纖行業(yè)10.06%。2010-2014年我國化纖行業(yè)毛利率增長較平穩(wěn)，起伏波動(dòng)較小。

據(jù)中國產(chǎn)業(yè)調(diào)研網(wǎng)發(fā)布的中國化纖行業(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，隨著經(jīng)濟(jì)的復(fù)蘇和發(fā)展，在國際紡織品服裝市場(chǎng)需求繼續(xù)保持增長趨勢(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)保持增長態(tài)勢(shì)，我國化纖及其制品憑借較為明顯的國際競(jìng)爭(zhēng)優(yōu)勢(shì)，國際市場(chǎng)還有繼續(xù)擴(kuò)大的空間。

e 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.
