As you view the graphics, the idea is to develop the concept of polarity in a visual manner. The more areas of red and blue that you see, the more polar is the compound and the functional group in the compound. Look at the amide, and acid. The more areas of gray and lighter shades of red and blue, the more non-polar properties are being depicted. Look at the amine, ether, and alkane.
Delicacy. Although silk is valued for its delicacy, that same delicacy is considered a disadvantage of the fabric. Silk fades easily in direct sunlight, so a new garment dried outside can look old and worn. The fabric has a tendency to develop a yellow color over time and is particularly prone to perspiration stains.ilk is generally used for clothing such as blouses, dresses and ties, but it can also be used to make sheets and curtains. It has a fine, elegant and delicate appearance, but as a fabric, it has several disadvantages.
Technically, silk does not shrink like other fibers. If the fabric is not tightly woven, washing a silk will tighten up the weaveâ¦. thus, lighter weights of silk (say a crepe de chine of 14 mm) can be improved by washing as it will tighten up the weave.ilk, or soie in French, is the strongest natural fiber. A steel filament of the same diameter as silk will break before a filament of silk. Silk absorbs moisture, which makes it cool in the summer and warm in the winter. Because of its high absorbency, it is easily dyed in many deep colors.
