铜氨纤维筒子纱染色实践

The package dyeing practice of Cuprammonium fiber

根据铜氨纤维湿纱缩水、耐热性、耐碱性、耐酸性、抗氧化性特性,合理制定染色工艺,保证染纱质量,有利于铜氨纤维选择工艺路线;选择合适染色工艺后,强力降低小,干摩、湿摩牢度指标均达到染色后纱线技术标准,保持了铜氨纤维特有的品质。

Based on the cuprammonium＇ s characteristics of wet yarn shrinkage, thermal resistance, alkali resistance, acid resistance, oxidation resistance, a reasonable dyeing process was developed to ensure the quality of yam dyeing and be conducive to the copper ammonia fiber selection process route. A optimum dyeing process was chosen with strength reducing slightly, dry robbing, wet robbing fastness indicators reaching the yarn after dyeing technical standards, and maintaining the unique quality of the copper ammonia fiber.
