白油的下游用途之化纤和纺织行业
文章作者:admin 上传更新:2019年10月16日


据隆众统计的数据显示,2018年国内白油产量为195.55万吨,其中工业白油占比约为43%。2018年白油供应整体增加,需求平稳,总体依旧是供大于求的趋势。而国庆节之后的行情上涨,是由于资源偏紧引起的,属于短期的市场行为。


随着我国经济水平的不断提升,白油的应用也较为广泛。按照目前国家标准来划分,白油主要分为:粗白油,轻质白油,工业白油,化妆品级白油,食品级白油和医药级白油。而化妆品级以上的白油我们统称为高档白油。综合国内装置看,高档白油产能约占18%左右,但是实际产量却不足白油总产量的10%,因此目前国内的高档白油市场依旧以进口资源为主。今天我们主要来看一下工业白油在下游化纤和纺织助剂中的应用。


工业白油在整个白油行业是重中之重,下游的主要应用领域中化纤和纺织行业占比较高。


在化学纤维加工过程中,要提高加工效率、质量及产品性能,就必须使用化纤油剂。我国是化纤生产大国,随着化纤总量的增加,对油剂用量的需求越来越大,质量需求越来越高。化纤油剂按其应用可分为:涤纶油剂、腈纶油剂、丙纶油剂、锦纶油剂、维纶油剂和粘胶纤维油剂等;按照合成纤维的品种可分为:长丝油剂和短丝油剂。在短丝纤维加工过程中,含油量一般控制0.1%~0.5%之间;长丝的含油量一般控制在0.5%左右,后加工油剂一般控制在2%左右。化纤油剂主要由平滑剂、乳化剂和抗静电剂等组成。白油作为开发较早而且廉价易得的一种原料,在化纤油剂中主要用做平滑剂。因不同纤维加工过程中对油剂要求不同,其相应的油剂所需的平滑剂也不相同。白油在涤纶DTY油剂、涤纶FDY油剂、丙纶油剂、锦纶油剂、人造纤维油剂等中属于基础油,用量较大,其用量占油剂组成的30%—90%,甚至更高。华东和华南地区是国内化纤和纺织行业用油集中地。


2019年国内新增白油产能预计在134.5万吨左右,新上装置以工业白油为主,国内白油供应过剩成常态,稳定的产品质量和优质的售后服务将成为生产厂家提高市场占有率的关键。

According to lonzhong statistics, China's white oil production in 2018 was 1.9555 million tons, among which industrial white oil accounted for about 43 percent. In 2018, the overall supply of white oil increased and the demand remained stable, which was still a trend of oversupply. After the National Day rise in prices, is due to tight resources caused by a short-term market behavior.




With the continuous improvement of China's economic level, white oil is widely used. According to the current national standards to divide, white oil is mainly divided into: crude white oil, light white oil, industrial white oil, cosmetic grade white oil, food grade white oil and medical grade white oil. And cosmetic grade above white oil we are collectively referred to as high-grade white oil. In terms of domestic installations, the production capacity of high-grade white oil accounts for about 18%, but the actual output is less than 10% of the total output of white oil. Therefore, the domestic high-grade white oil market is still dominated by imported resources. Today we will focus on the application of industrial white oil in downstream chemical fiber and textile auxiliaries.




Industrial white oil is the most important in the whole white oil industry. Chemical fiber and textile industry account for a high proportion in the main application fields of downstream.




In the process of chemical fiber processing, it is necessary to use chemical fiber oil agent to improve the processing efficiency, quality and product performance. China is a major producer of chemical fiber. With the increase of the total amount of chemical fiber, the demand for oil is more and more large, and the demand for quality is more and more high. According to its application, chemical fiber oil agent can be divided into: polyester oil agent, acrylic oil agent, polypropylene oil agent, nylon oil agent, vinylon oil agent and viscose fiber oil agent; According to the variety of synthetic fiber can be divided into: filament oil agent and short filament oil agent. In the process of staple fiber processing, the oil content is generally controlled between 0.1% and 0.5%. The oil content of filament is generally controlled in about 0.5%, after processing oil agent is generally controlled in about 2%. Chemical fiber oil is mainly composed of smoothing agent, emulsifier and antistatic agent. White oil, as a kind of raw material which was developed earlier and available cheaply, is mainly used as smoothing agent in chemical fiber oil. Because of the different requirements on the oil in the process of processing different fibers, their corresponding oil required smoothing agent is not the same. White oil in dacron DTY oil agent, dacron FDY oil agent, polypropylene oil agent, polyamide oil agent, artificial fiber oil agent, etc. belong to the base oil, the amount of large, its amount of oil composition of 30% - 90%, or even higher. East and south China is the concentration of chemical fiber and textile industry oil.


The new domestic production capacity of white oil is expected to be about 1.345 million tons in 2019. The new installation is mainly industrial white oil, and domestic white oil oversupply has become a normal situation. Stable product quality and high-quality after-sales service will become the key for manufacturers to improve their market share.
