为提高细旦涤纶的染色上染率,采用氧低温等离子体技术对其进行了改性研究。探讨氧等离子体放电时间、放电气压和放电功率对细旦涤纶润湿性、结晶度、表面热力学电位(Ψ电位)以及上染率的影响规律。结果表明:在最佳工艺条件下,细旦涤纶的上染率提高了17％左右,显著减少印染废水中的污染物排放量。经时效应实验结果表明润湿性不随放置时间衰减。
In order to improve the dyeing rate of fine denier polyester, oxygen low-temperature plasma technology was used to modify it. The effects of oxygen plasma discharge time, discharge pressure and discharge power on the wettability, crystallinity, surface thermodynamic potential (Ψpotential) and dye uptake of fine denier polyester were investigated. The results showed that under the optimum conditions, the dyeing rate of fine denier polyester fibers increased by about 17%, significantly reducing the discharge of pollutants in printing and dyeing wastewater. The results of the aging effect show that the wettability does not decay with the placement time.
