锌氨改性竹浆纤维的抗紫外性能研究

Research on Anti-ultraviolet Capability of Bamboo Pulp Fiber Modified by Zinc Ammonia

用锌氨溶液处理竹浆纤维使其功能化,得到锌氨改性竹浆纤维。对改性的竹浆纤维织物进行水洗牢度实验,从锌氨溶液的配制质量浓度、处理试样的烘干条件及抗紫外效果的耐久性等3个方面研究了锌氨改性竹浆纤维的抗紫外性能。结果表明:通过锌氨溶液处理,赋予了竹浆纤维很好的抗紫外性能,完成了功能化改进;同时改性的竹浆纤维具有一定的水洗牢度;锌氨溶液的浓度在0.1 mol/L以上时,处理后的改性竹浆纤维的抗紫外性能较佳,其UPF值超过50,水洗240 min后,抗紫外性能基本保持不变。由于锌无味无害,且改性后的锌氨竹浆纤维织物呈白色,对染色也不会有影响。

This paper uses zinc ammonia solution to process bamboo pulp fiber to functionalize it and obtains bamboo pulp fiber modified by zinc ammonia; conducts washing fastness test on modified bamboo pulp fiber fabric and studies the anti-ultraviolet capability of bamboo pulp fiber modified by zinc ammonia from the mass concentration of zinc ammonia solution, stoving conditions of processing sample and durability of anti-ultraviolet effect. The result shows that bamboo pulp fiber is provided with a good anti-ultraviolet capability through zinc ammonia solution processing and functional improvement is completed. Meanwhile, modified bamboo pulp fiber has a certain washing fastness. When the mass concentration of zinc ammonia solution is over 0.1 mol/L, modified bamboo pulp fiber after processing has a good anti-ultraviolet capability. Its UPF value exceeds 50. After washing for 240 min, its anti-ultraviolet capability basically remains the same. As Zn is tasteless and harmless and modified zinc ammonia bamboo pulp fiber fabric is white, dyeing will not be influenced.
