Coach bags have historically been renowned for their use of high-quality leathers and materials. However, in their wide range of products, Coach also utilizes a variety of other materials, including canvas and PVC (Polyvinyl Chloride), especially in their Signature line of bags. The use of PVC in certain designs is largely due to its durability, ease of maintenance, and affordability, making it an appealing choice for consumers looking for luxury designs without the premium price of leather. These PVC bags often feature the iconic Coach pattern and offer a different aesthetic and functionality. While leather remains a significant part of Coach's legacy and premium product line, the inclusion of PVC allows for a broader range of products to suit diverse consumer preferences and needs.

Polypropylene fabric, commonly used in activewear, bags, and rugs, is known for its durability and resistance to stains, mold, and mildew. When washing polypropylene fabric, it’s vital to use a gentle cycle with cold water to prevent any potential damage or shrinkage. Using a mild detergent is recommended, as harsh chemicals can break down the fibers over time. It’s also beneficial to avoid bleach, which can deteriorate the fabric's strength. For drying, either air dry or use a low heat setting in the dryer. Avoid high temperatures, as polypropylene has a low melting point. A soft brush can be used for removing dirt before washing, especially in cases of rugs or mats. This care routine ensures the longevity and maintains the quality of your polypropylene items.
Pigments absorb radiation across various wavelengths, primarily in the visible spectrum (390-700 nm), but this varies widely among different pigments. Chlorophyll, the key pigment in photosynthesis, mainly absorbs light in the blue (around 430-450 nm) and red (around 640-680 nm) regions, reflecting green, which is why plants appear green. Other pigments, like carotenoids, absorb in the blue region (400-500 nm), reflecting yellow, orange, or red colors. The specific wavelengths absorbed depend on the pigment's chemical structure, which determines its electron configuration and, consequently, the energy levels it can absorb. This selective absorption and reflection of light wavelengths are fundamental to processes like photosynthesis and also influence the colors we perceive in the natural world.
