Know The Fiber That Covers your Skin
|Ø Synthetic fiber derived from petroleum, basically plastic.
Ø Polyester is hydrophobic in nature and hardly allows moisture through the fabric. When we sweat, sweat drop begin to deposit on our skin as garment is unable to regain moisture. The polyester garment wearer can feel discomfort and sweaty.
Ø Polyester is non breathable and resists water on its surface. Moisture vapor transmission is relevant to the nature of the fiber. Polyester doesn’t allow moisture on its surface therefore it cannot pass vapor easily through the pore of the fabric.
Ø Polyester is highly sensitive to static electricity and polyester clothes remain cling next to skin causing discomfort. Small gap between garments and skin traps hot air, as polyester is a less air permeable fiber, discomfort can cause. Human dry skin & hair is charged positively whenever it rubbed with other materials like polyester.
Ø Friction of polyester with the skin creates some sort of sound that can create discomfort wearing polyester. Polyester can cause discomfort like itchy, tickling, harsh feeling and rashes.
Ø Polyester is harsh on hand feel
Ø Polyester produces negative charge while abrasion
Ø Non breathable polyester cannot release the air trapped between the polyester clothes and the skin. Air getting body temperature retains heat. This increase the temperature and discomfort.
Ø Polyester is synthetic fiber and originates from petrochemical
Ø Polyester is neither biodegradable not sustainable.
Ø Polyester weights light, has a better thermal insulation for winter clothing
Ø Polyester has a fair wind resistance
Ø Polyester has 4% shrinkage (100 wash results)
Ø Polyester takes short time to dry
Ø Polyester has 8% loss of strength
Ø Polyester is recyclable
Ø Polyester needs less water to produce
Ø Polyester uses oil and gas reserves. Its life cycle starts with oil extraction
Ø Polyester is not landfill biodegradable
|Ø A natural fiber from cotton plant, cellulose based.
Ø Cotton fiber is absorbent, owing to the countless polar -OH groups in its polymers; these attracts water molecules. Cotton can absorb our perspiration leaving the cotton garment wearer with a comfortable feel.
Ø Cotton is breathable. Due to the hydrophilic nature of cotton it attracts moist vapor in its surface and then begins to transfer the vapor though the garments. When a fabric allows the transport of water vapor at a faster rate, it is said to be a breathable fabric.
Ø Cotton is the neutral in static charge. That means it does not react with other matters when it is rubbed with other materials. Cotton is best for non-static clothes.
Ø Cotton gives a better sensorial comfort, which means a better effect of fabric properties on human skin. Cotton creates a smooth and gentle fabric. It is uncommon to get allergic reactions when wearing cotton clothes (untreated to various finishes like “repellent” or “retardant”). Cotton is less hazardous.
Ø Cotton is soft on hand feel
Ø While abrasion, cotton does not produce any charge
Ø Cotton clothes has a better contact with the skin and due to its breathable property, cotton releases air between the cotton garment and skin into the environment helping skin stay cool.
Ø Cotton crop uses lot of synthetic fertilizers and pesticides, unless it is grown organically
Ø Cotton is sustainable, renewable and biodegradable
Ø Cotton weights medium and has a lower thermal insulation for winter clothing.
Ø Cotton has a good wind resistance
Ø Cotton has 7% shrinkage (100 washes)
Ø Cotton takes long time to dry
Ø Cotton has 17% loss of strength after 100 washes
Ø Cotton is recyclable
Ø Cotton crop needs higher amount of water
Ø Cotton grows on plant. Crop uses pesticides and fertilizers, unless organic
Ø Cotton is landfill biodegradable
