Textiles
Understanding Textiles
- Textiles are flexible materials consisting of a network of natural or artificial fibres, often referred to as threads or yarns.
- Textiles are formed through various methods, such as weaving, knitting, crocheting, tatting, felting, or braiding.
- The fibres that make up textiles can be obtained from various sources, including sheep’s wool, cotton from cotton plants, silk from silkworms, and synthetic fibres from petrochemicals.
- The quality and properties of a textile can vary widely depending on its composition and the manufacturing process used.
Types of Textiles
- Natural Fibres: Derived from animal, plant, or mineral sources, such as cotton, silk, and wool. They tend to be breathable and comfortable against the skin.
- Synthetic Fibres: Created through chemical processes using substances like petrochemicals. Examples include nylon, polyester, and acrylic. They are durable and resistant to specific conditions.
- Regenerated Fibres: Made by processing natural materials into a fibre structure. Examples include rayon and lyocell.
- Blended Fibres: These textiles mix different types of fibres to combine their properties.
Properties of Textiles
- Textiles can be lightweight or heavy-duty, flexible or rigid, absorbent or water-repellant.
- They are available in a wide range of colours and patterns, allowing for wide variation in aesthetic appeal.
- Some textiles are heat-resistant, making them suitable for protective gear and industrial applications.
- Certain textiles have antimicrobial properties or can be treated to become antimicrobial, making them suitable for medical use.
Applications of Textiles
- Textiles are widely used in the fashion industry for clothing and accessories.
- They are essential in home furnishings, including bedding, upholstery, carpets, and curtains.
- In industry, textiles are used for products such as filters, geotextiles and medical implants.
- Some specialised textiles are used for industrial, extreme weather, and defensive clothing, as well as the production of tyres and other industrial products.
Environmental Impact of Textiles
- The production of textiles, particularly synthetic fibres, can have a substantial environmental imprint in terms of energy use and pollution.
- Many textiles are not biodegradable, and their production uses substantial amounts of water.
- However, sustainable textiles and eco-friendly manufacturing processes are increasingly being developed and utilised.
- Life cycle assessment (LCA) can be applied to understand the full environmental impact of a textile product, from fibre production to end-of-life.
Manufacturing Techniques
- Textile production processes include spinning (production of yarns), weaving or knitting (fabric production), dyeing and finishing (adding colour and improving aesthetics/performance).
- Some textiles can be produced directly in 3D shapes, reducing the need for cutting and sewing.
- Processes for combining textiles with other materials include lamination and the incorporation of membranes or coatings to modify properties.
