专利汇可以提供Process for dyeing of novoloid fibers专利检索，专利查询，专利分析的服务。并且A process for dyeing novoloid fiber without changing the thermal properties or altering the hand (textural quality or feel). After scouring and rinsing, the fabric is placed in an enclosed container with water, 1 - 5 grams per liter of a carrier such as Butyl benzoate and 0.10 - 10.0 per cent of a basic dye, such as Victoria Green Crystals. The pH in the container is maintained at approximately 4.5 to 6.5 with acetic acid or another suitable chemical. The temperature is raised at an approximate rate of 2 Farenheit degrees per minute from 100*F to 240* - 300*F and then held for at least 1 1/2 hours at that temperature. The container is cooled to 140*F - 180*F, rinsed until clear and the fabric removed. Finally, the fully relaxed fabric is extracted and framed dryed at 250*F - 350*F.，下面是Process for dyeing of novoloid fibers专利的具体信息内容。
