ответ: 1. Because of the hydrogen bonds, which break when cotton get wet or sweaty
2. Because it`s either toxic or stink, so the clothes don't last long and they aren't very healthy to wear.
No, i can't, because i think (that) it's kind of an unprofitable chemical. For example dimethylol dihydroxy ethylene urea (DMDHEU) isn't so expensive, it doesn`t turn yellow and it isn`t toxic, therefore formaldehyde is a useless chemical.
3. Yes, it was. Because while Patsy was working on a latex rubber compound for tubes, she split a little of the substance on her canvas shoes. And after some time she noticed that where the latex compound had dropped on her shoe, the shoe stayed clean. This is how Scotchgard was accidentally invented.
4. Because the Nano-Tex creates fibres that still feel soft and natural, but which are strong and wearing, don't crease and stains just fall off them unlike the Scotchgard, which doesn't feel very nice.
5. Because it makes the fabric hydrophobic so the droplets of water just balance on top, but never soak into the material.
6. Hydrophobic is tending to repel or fail to mix with water. For example the silicon, which doesn't soak the droplets of water into the fabric.
7. No, i can't :))

Олімпійські ігри були спочатку релігійним святом стародавніх греків на честь Зевса, які проводилися в Олімпії біля гори Олімп, міфічного житла богів. Початкова дата ігор склала 776 р. до н. е. Вони проводилися кожні чотири роки, посеред літа; головною умовою фестивалю було встановлення миру усюди в Греції. Церемонії включали змагання в ораторстві, поезії, музиці, і мистецтві, також як і в атлетичних дисциплінах як боротьба, метання спису і біг.
Олімпійські ігри були виключно чоловічим святом, відкритим для молодих чоловіків з усіх грецьких міст. Жінкам не дозволялося змагатися в Олімпійських іграх або навіть відвідувати ігати їх, хоча є легенди про дівчаток, які замасковувалися. Переможці були традиційно короновані оливковим листям замість золотих медалей. їх важливість в грецькому житті була такою великою, що Олімпіада, з чотирирічним інтервалом між іграми, була головною одиницею грецького календаря. Бути переможцем в класичних Олімпійських іграх було великою честю не тільки для атлета, але і для його міста.
