Give 5 disadvantages of terylene
The Correct Answer and Explanation is :
Terylene, also known as polyester (PET), is a synthetic fiber widely used in textiles, packaging, and other applications. However, despite its many advantages, there are several notable disadvantages associated with terylene. Below are five key disadvantages:
- Non-biodegradable:
Terylene is made from petrochemical products and is not biodegradable. This means it persists in the environment for many years, contributing to plastic pollution. Once discarded, it does not break down naturally, leading to environmental issues such as landfill accumulation and ocean pollution. - Poor moisture absorbance:
Unlike natural fibers like cotton or wool, terylene has poor moisture-absorbing properties. It does not wick away sweat or moisture efficiently, which can make it uncomfortable to wear, especially in hot or humid conditions. This is a significant drawback for clothing items intended for athletic or active wear. - Prone to static electricity:
Terylene tends to generate static electricity, especially in dry conditions. This can lead to clothing clinging to the body and an increased likelihood of static shocks. The accumulation of static electricity also attracts dust and dirt, reducing the cleanliness and appearance of terylene fabrics. - Limited breathability:
Terylene fabrics are less breathable compared to natural fibers. This reduced airflow can make clothing items made from terylene feel hot and uncomfortable, especially in warmer climates. The lack of breathability can lead to discomfort, and in some cases, skin irritation. - Difficult to dye:
Terylene is more challenging to dye compared to natural fibers. The polyester fibers require special dyeing techniques and high temperatures, making the process less efficient and more expensive. This can limit color variety and make terylene clothing harder to customize or match specific design requirements.
Explanation:
Terylene is a strong, durable, and versatile synthetic fiber, commonly used in textiles, packaging, and even in the automotive industry. However, its drawbacks stem from its chemical composition and structure. The fact that it is non-biodegradable means it accumulates in landfills, posing significant environmental challenges. Its poor moisture absorption and limited breathability make it less suitable for certain types of clothing, particularly for activewear, where moisture-wicking properties are essential. The tendency of terylene to generate static electricity is another drawback, making it less comfortable to wear and harder to maintain. Additionally, the difficulty in dyeing terylene fabrics means it’s less versatile in terms of aesthetic flexibility compared to natural fibers. Despite these disadvantages, terylene’s durability, low cost, and ease of care make it a popular choice for many applications, though its environmental impact remains a significant concern.
