洗衣粉去漬的原理

洗衣粉是洗衣服時，添加溶解在水中來清洗，使衣服更容易洗淨的粉狀物。

洗衣粉的成分一般主要包括表面活性劑、軟水劑、鹼劑、漂白劑等，其中一些化合物或造成水污染。

因為洗衣粉內有可以clean污漬chemicals . 要解釋原理首先要知道什是污漬 , 它如何會弄污衣服 , 又如何由污糟衣服洗干淨呢 ?? To cut the story short , I will only mention how stain is removed from dirty clothes ,
當污漬黏在衣服上 , 如果只用清水 , 只能洗去很少污漬 . Stain is a complex soil , water can only dissolve the surface part of the soil which is water soluble . 因為水surface tension is high that it cannot wet the soil so it can dissolve the outside part of the soil . 所以加洗衣粉落水 , 它內有surface active agents 來降低水表面張力(由72dyes per cm to 35-45 )所以水能wet濕潤污物 , 跟著penetrate the soil . 而洗衣粉內還其他chemicals which can solubize oily stains . To make the story simple , the cleaning process is :
first wet , then penetrate , follow dissolve , solubize , emulsify , finally soils are replaced from clothes(substrate) , disperse in cleaning solution(willnot resettle back to the clothes) , finally rinsing away . 其中有機械力量 : 手捽擦或洗衣機轉動來幫助化學上之清洗 . Sorry 以上有用英文寫 , 因中文''掌心雷''寫極都寫不出來 .
