澳洲您正在打扫衣服！科学家揭示了摆脱黄色污渍的最佳方法 - 而不是漂白剂

在澳大利亚中文新闻



黄色的汗染是一件白色衬衫的最大敌人。

，当您首先注意到时，很容易到达漂白剂。

及其所需的只是蓝色LED光。

日本研究人员测试了不同的果汁，番茄果汁，牛油果汁和汗液的物质引起的去除污渍的方法。 high-intensity blue LED light – which removed stains substantially more than bleach or UV exposure.

‘Our method utilises visible blue light in combination with ambient oxygen, which acts as the oxidising agent to drive the photobleaching process,’ author Tomohiro Sugahara said.

‘This approach avoids常规漂白方法中通常需要使用的硬化学氧化剂，使其内在更可持续。 src =“ https://i.dailymail.co.uk/1s/2025/09/09/05/101871079-1506-15069243-IMAGE-IMAGE-IMAGE-A-34_175708383878782.JPG”高=科学家说，与他们打交道的最佳方法不涉及漂白（库存图像）“ class =“ blkborder img-share” style =“ max-width：100％“ loading =“ lazy” />

露出麦片上的汗液（左led），<左LED（左），黄色染色是由山比和汗水中的沙丘和油酸引起的。

用于实验，研究人员将棉片施加到棉织物上，并为他们加热以模拟时间。通过将它们浸泡在过氧化氢（漂白剂）溶液中或将其暴露于紫外线或蓝色LED光。

分析显示，蓝光大大减少了黄色的污渍，大幅度降低了过氧化氢或紫外线的暴露。 compounds.

Additional tests showed that the blue LED treatment lightened squalene stains on silk and polyester without damaging the fabrics.

The method also reduced the colour of other stain-causing substances, including aged oleic acid, orange juice and tomato juice, on cotton swatches.

科学家说，他们想将轻型系统商业化用于家庭和工业用途 - 但需要先进行其他安全测试。

可能很诱人的情况下，发现蓝色LED = < /pract

科学家警告可在流行的家用电器中生存，您使用每周

Writing in the journal ACS Sustainable Chemistry & Engineering, the team said: ‘Textile bleaching methods for commercial and domestic use, such as hydrogen peroxide bleaching, often depend on oxidizing agents, solvents, and heat, making them unsuitable for delicate fabrics and demanding large amounts of energy and chemicals.

‘This study presents a new photobleaching method for removing yellow stains from clothing.

‘This technology reduces the environmental impact of bleaching by avoiding conventional oxidizing agents such as hydrogen peroxide (bleach).

‘Its solvent-free nature enables its use on delicate textiles, making it a promising sustainable cleaning方法。’

您应该使用多少洗涤剂？

粗略地说，您需要两个大量的大量负载，但只有一汤匙才能用于较小的负载。

Manual Manual Manual'>洗衣机>设备。 

这将以程序为基础进行详细介绍，因此您将用于全额负载比半载荷的全部负载。我们大多数人在usin时弄错了g猜测和最终使用过多。
