再生聚酯在纺纱时需加入纺丝油剂,油剂会影响后续染色过程。为减少油剂对后续染色过程的影响,采用超临界CO2流体萃取法,研究了再生聚酯纱线在超临界体系下的除油效果,选取除油温度、压力、时间、CO2流量作为研究因素,利用响应面法对工艺条件进行优化,采用扫描电镜和红外光谱分析进一步对除油后纱线性能进行探究。结果表明:最佳工艺条件为除油温度64℃,除油压力21 MPa,除油时间60 min, CO2流量415 kg/h,在此条件下再生聚酯纱的除油率可达到78%,超临界CO2除油后的纱线表面油剂有一定减少,纱线物理结构未受到影响。 相似文献

目前在BCF地毯纱中,丙纶纤维占50%以上,去年全球产量达210万吨。纺丝油剂的主要功能是调节摩擦力包括纤维/金属间、纤维/纤维间摩擦力,调节纱线抱合力和抗静电性。纤维/纤维间摩擦力必须保证卷装成形和丝束在织造和簇绒过程中的抱合力,而PP专用纺丝油剂中助剂还必须有最大润湿和分散性能,以便油剂接触纤维后可立即覆盖表面,油剂的表面覆盖性越好,在导丝辊上的摩擦控制就越好, 相似文献

分析了羊绒围巾功能性整理(抗静电整理、机可洗整理、三防整理等)的原理,并对助剂和工艺路线选择、整理工艺、检测数据及结论进行了分析说明。抗静电整理的方法是加入导电纤维或抗静电助剂;机可洗的整理方法是通过防缩助剂整理,消除羊绒的定向摩擦效应,达到防毡化收缩的效果;三防整理的方法是加入三防助剂进行整理,在织物表面产生聚合物薄膜,使织物临界表面张力变小,不易被油所润湿,并兼有拒水性。 相似文献

Frozen par-fried French fries are finish-fried either by using the same type of oil used for par frying, or a different type. The nutritive quality of the final oil contained in the product depends on the relative amounts and the fatty acid (FA) composition of the oils used for par frying and finish frying. With the aim of understanding the provenance of the oil in the final product, par-fried French fries-either purchased ready or prepared in the laboratory-were finish fried in oils different from the ones used for par frying. The moisture content, oil content, and FA compositions of the par-fried and finish-fried products were experimentally determined, and the relative amounts of each of the oils present in the final product were calculated using the FAs as markers and undertaking a mass balance on each component FA. The results demonstrate that 89% to 93% of the total oil in the final product originates from the finish-frying step. The study also shows that a significant proportion of the oil absorbed during par frying is expelled from the product during finish frying. Further, the expulsion of par-frying oil was found to occur in the early stages of the finish-frying step. Experiments involving different combinations of par-frying and finish-frying oils showed that the relative proportions of the 2 oils did not depend on the individual fatty acid profiles. This study concludes that any positive health benefits of using an oil having a favorable FA profile for par frying, can potentially be lost, if the oil used for finish frying has a less favorable composition. PRACTICAL APPLICATION: This paper estimates the relative amounts of oil in French fries that have been fried in 2 stages-a par-frying step and a finish-frying step-which is commonly practiced in food service establishments as well as homes. The 2 key conclusions are: (1) nearly 90% of the oil content of the final product is the one used for finish frying; that is, a processor may use very good oil for par frying but if the oil used for finish frying is inferior, its effect will dominate. (2) The paper also shows that a significant proportion of the oil used by the processor gets expelled during finish frying. 相似文献
