Polythene Fibre in Textile: Meaning, Definition, and Explanation

Polythene fibre, also known as polyethylene fibre, is a synthetic material widely used in the textile industry. It is derived from polyethylene, a thermoplastic polymer, and possesses unique properties that make it suitable for various applications. This article provides a comprehensive understanding of polythene fibre, including its history, types, tips for handling, and profiles of top international users and manufacturers.

History and Origin

Polyethylene, the base material for polythene fibre, was first synthesized by German chemist Hans von Pechmann in 1898. However, its commercial production began in the 1930s, when scientists at Imperial Chemical Industries (ICI) developed a high-pressure polymerization process. This breakthrough led to the large-scale production of polyethylene, paving the way for the development of polythene fibre.

Types of Polythene Fibre

Polythene fibre comes in various types, each with its own characteristics and applications:

1. High-Density Polyethylene (HDPE) Fibre: HDPE fibre is known for its high strength and stiffness, excellent chemical resistance, and low moisture absorption. It is commonly used in applications requiring durability and dimensional stability, such as ropes, nets, and geotextiles.
2. Low-Density Polyethylene (LDPE) Fibre: LDPE fibre offers flexibility, good impact resistance, and a soft feel. It is commonly used in applications where comfort is essential, such as in woven or non-woven fabrics for clothing, bedding, and medical products.
3. Linear Low-Density Polyethylene (LLDPE) Fibre: LLDPE fibre combines the properties of both HDPE and LDPE fibres, offering a balance of strength, flexibility, and chemical resistance. It finds applications in various industries, including packaging, agriculture, and textiles.

Tips for Handling Polythene Fibre

To ensure proper handling and maintenance of polythene fibre, the following tips should be considered:

• Storage Conditions: Polythene fibre should be stored in a cool, dry place away from direct sunlight to prevent degradation.
• Protection from Heat: Exposure to high temperatures can cause melting or deformation of polythene fibre. Care should be taken to avoid contact with hot surfaces or sources of heat.
• Proper Cleaning: Cleaning instructions provided by the manufacturer should be followed to maintain the integrity and longevity of polythene fibre products.
• Avoid Sharp Objects: Polythene fibre is susceptible to cutting or tearing when in contact with sharp objects. Caution should be exercised to prevent damage during handling and use.
