| 涤纶除油剂按照工艺来分，一般分为高温除油剂和低温除油剂。高温除油剂目前相对比较成熟，按照作用原理来看可以分为3类：第一类是碱性除油剂，类似于传化TF-101系列，这种产品主要用于涤纶化纤的梭织物上，用于碱减量时，集退浆、精炼一体，而针织物一般不需要碱减量（超细旦纤维和海岛纤维除外）。第二种原理，就是现在市场上炼染同浴的除油剂，这些除油剂就需要分散性非常好的产品，能将除出来的油分散在水中，不影响染色，以相似相容原理开发的新产品为最佳。第三种就是萃取法，类似于用四氯化碳等产品来吸取油剂，但这种方法目前很少有人使用。高温除油剂由于工艺成熟，使用的表面活性剂也比较简单，最早有NP、磺酸、6501等产品，后来由于环保要求，客户性能要求的提升，换成了AEO、SAS-60、C13、EH等异构醇醚。 Polyester degreasing agent is divided into high-temperature oil removal agent and low temperature degreasing agent according to technology. High temperature degreasers are relatively mature at present, and can be divided into three categories according to the principle of action: the first is alkaline degreaser, similar to the TF-101 series, which is mainly used in polyester chemical fiber woven fabrics, for alkali deweighting, desizing, refining in one, and knitted fabrics generally do not need alkali deweighting (superfine denier fiber) Except for peacekeeping Island fibers. The second principle is the same bath degreaser for refining and dyeing on the market now. These degreasers need products with very good dispersibility. They can disperse the degreased oil in water without affecting dyeing. New products developed on the principle of similarity and compatibility are the best. The third is extraction, similar to the use of carbon tetrachloride and other products to absorb oil, but this method is currently rarely used. High-temperature deoiling agent due to the mature process, the use of surfactants is relatively simple, the earliest NP, sulfonic acid, 6501 and other products, but later due to environmental protection requirements, customer performance requirements, instead of AEO, SAS-60, C13, EH and other isohydric alcohol ethers. |
