Study Notes
Textiles - Fibres
- Fibres are the basic building blocks of textiles
- Two main types: Staple (short strands like cotton) and Filament (continuous strands like silk).
- Staple fibre quality depends on fineness and length.
- Filament fibre quality is more about the intended use.
- Fibre supply chains are complex, involving natural and manufactured materials.
- Significant environmental concerns linked to water and energy usage in both natural and synthetic fibre production.
- Mechanical reuse and chemical recycling of fibres.
- Conservation of fibre supply is an important concern for designers.
Classification of Fibers
- Fibers are categorized into natural (vegetable and animal) and man-made fibers.
- Natural fibers are primarily cellulose or protein based.
- Cellulose fiber examples include cotton hemp and linen.
- Animal Fiber examples include wool and silk.
- Man-made fibers are synthetic fibers.
- Fiber identification methods include visual inspection, labels noting care instructions and tests conducted in a laboratory.
Textile Fibers (Diagram)
- Natural fibers are divided into animal and plant fibers.
- Man-made fibers are categorized into fibers derived from natural polymers and synthetic fibers.
- Subcategories are listed for both natural and man-made fibres.
Special Identification Test
- Physical test, burning test and microscopic test used to identify different types of fiber.
- Burning tests are carried out carefully to identify natural or man-made fibers; identifying the colour of ash and flame characteristics.
- Breaking or tearing tests can also be used to differentiate fibres.
- Observations of microscopic structures provide additional identification.
Cotton Fiber
- Cotton is a common and versatile natural fiber, popular for a wide range of uses, ranging from basic clothes to designer fashion.
- Different grades and processing methods of cotton (carded or combed) impact its texture and smoothness.
- 'Luxury' types of cottons exist with longer staples, such as Egyptian, Sea Island, Pima, and Supima.
- Cotton lisle and Mercerized cotton are treated forms of yarn resulting in special qualities.
Linen Fiber
- Linen is a natural plant fiber from flax plants; known for its durability and coolness.
- Linen's handle is known for its distinctive texture.
- Linen is used in both casual and formal, durable or luxurious clothing.
- Linen tends to be superior to cotton in terms of fabric strength and absorbency.
Wool Fiber
- Wool is a natural animal fiber known for its warmth and softness.
- Wool fibers are characterized into different quality classes.
- Wool class differences arise from processing techniques and fibre diameters.
- Wool production involves shearing, classifying and a series of further processing.
Silk Fiber
- Silk is a natural protein fiber with a characteristically smooth and lustrous texture.
- The silk-producing moth (Bombyx mori) creates the fibre in cocoons.
- Raw silk undergoes processing to produce smooth threads or yarns for use in making fabric.
- Wild silks differ in appearances because of unique variations in moth species, climate conditions and so on.
Synthetics and Artificial Fibers
- Man-made fibers are created from different materials, and have their exact properties derived from the need for a particular application.
- Synthetics are derived from chemical compounds; artificially, from plant cellulosics.
- These are often blended with natural fibers to benefit from their unique characteristics in quality, comfort and cost.
Weaves
- Plain, twill, and sateen are common weaving techniques; each creating particular fabric appearances.
- Plain weave is the simplest.
- Twill weaves produce diagonal lines.
- Sateen and satin weaves feature smooth surfaces.
