概括
紫外线防护服的有效性可以在洗后显著下降,特别是当使用化学添加剂时. 一些织物保持高紫外线保护因子 (UPF) 没有这些完成,表明需要可持续的替代品.
科学领域:
- 织科学 织科学
- 皮肤病学 皮肤病学
- 环境健康 环境健康
背景情况:
- 紫外线 (UV) 辐射对皮肤构成风险;传统的防晒主要阻UV-B,对UV-A的关注较少.
- 紫外线保护因子 (UPF) 评级的紫外线保护服提供物理屏障,但面临着披露和可持续性的担忧.
- 织品中的化学添加剂引发了关于环境释放和长期有效性的问题.
研究的目的:
- 评估商用紫外线保护服装在反复洗后的UPF值的耐用性.
- 调查洗对织品紫外线保护有效性的影响.
- 为了比较带有和没有披露的紫外线保护涂料的服装.
主要方法:
- 来自日光保护品牌的7种服装被测试了UPF值.
- 服装经历了多达50个洗周期 (冷水,商业洗剂).
- 在基线和每10次洗后记录UPF测量值.
主要成果:
- 两个品牌在50次洗后显示出明显的UPF降低 (70-78%);一个使用纳米,另一个使用未公开的方法.
- 五个品牌在整个洗测试中保持了稳定的UPF值.
- 披露的纳米涂料 (品牌A) 退化,而没有披露的涂料 (品牌G) 的织物保持稳定.
结论:
- 用于紫外线保护的织品涂料可能会随着洗而降解,从而降低了UPF的有效性.
- 一些织物保持UPF没有化学完成,质疑这种添加剂的必要性.
- 织品中可持续和持久的紫外线保护需要进一步研究材料组成和加工技术.

Mutations
38.2K
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
2.8K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...
