How is technology changing textiles, and what can smart and technical fabrics do that ordinary fabrics cannot?
Technological developments in textiles: smart textiles (reactive and responsive materials such as thermochromic, phase-change and conductive textiles) and technical textiles (high-performance fabrics for sport, medicine, protection and industry), and the impact of technology on manufacture.
An SQA Higher Fashion and Textile Technology answer on technological developments, explaining smart textiles such as thermochromic, phase-change and conductive fabrics, technical textiles for sport, medicine and protection, and how technology has changed textile manufacture.

What this key area is asking
Textiles are no longer only about clothing; technology has produced fabrics that react to their surroundings and fabrics engineered for demanding jobs. SQA Higher expects you to distinguish smart textiles from technical textiles, give examples and uses of each, and understand how technology has changed manufacture. Marks come from defining each type correctly, giving a real use, and linking the property to the benefit.
Smart textiles
- Thermochromic fabrics change colour with temperature (a mug-warming novelty, or a fabric that shows when a baby is too warm).
- Photochromic fabrics change colour with light (darkening in sunlight).
- Phase-change materials (PCMs) absorb and release heat to keep the wearer at a comfortable, steady temperature in sportswear and bedding.
- Conductive textiles carry electricity, used in heated clothing, wearable sensors that monitor heart rate, and flexible electronics woven into fabric.
Technical textiles
Technical textiles are engineered for performance in demanding settings:
- Sport. Moisture-wicking and breathable fabrics keep athletes dry and cool; compression fabrics support muscles.
- Medical. Sterile, biocompatible fabrics for dressings, bandages, sutures and implants.
- Protection. Flame-resistant fabrics for firefighters and high-strength fabrics (such as aramids) for protective and bulletproof vests, plus high-visibility and cut-resistant fabrics.
- Industrial and environmental. Filters, ropes, conveyor belts and geotextiles used in construction to stabilise soil and aid drainage.
The impact of technology on manufacture
Technology has changed how textiles are designed and made: computer-aided design (CAD) speeds up and refines design; computerised knitting, weaving and cutting improve accuracy and reduce waste; digital printing allows fast, detailed, low-waste prints and short runs; and automation increases speed and consistency. This makes production more efficient and can reduce environmental impact, though it also affects jobs.
Examples in context
Example 1. Heated motorcycle gloves. Gloves with conductive textiles carry a current from a battery to warm the hands - a smart textile responding to an electrical input. This does a job ordinary insulation cannot (active heating on demand), showing how smart materials add new functions to clothing.
Example 2. Geotextiles in road building. Strong geotextile fabrics are laid under roads and embankments to stabilise soil, separate layers and aid drainage. This technical textile performs a heavy-duty engineering function with no concern for appearance, illustrating how far textiles reach beyond clothing.
Try this
Q1. Define a smart textile and give one example. [2 marks]
- Cue. A smart textile senses and reacts to a change in its environment (temperature, light, moisture or an electrical signal); for example a thermochromic fabric that changes colour with heat, or a conductive fabric used for heated clothing.
Q2. Describe two uses of technical textiles. [4 marks]
- Cue. Sport (moisture-wicking, breathable fabrics keep athletes dry); medical (sterile dressings, sutures, implants); protection (flame-resistant fabric for firefighters, high-strength fabric for vests); industrial (filters, ropes, geotextiles). Develop any two.

SQA Higher style4 marksSmart versus technical textilesShow worked answer →
Worth 4 marks. "Distinguish between" means show clearly how the two differ.
Smart textiles (about 2 marks). Materials that react or respond to a change in their environment, such as temperature, light or an electrical signal, for example a thermochromic fabric that changes colour with heat. The fabric senses and responds.
Technical textiles (about 2 marks). High-performance fabrics chosen mainly for their function rather than appearance, used in sport, medicine, protection and industry, for example a high-strength fabric for a bulletproof vest. They perform a demanding job but do not necessarily react to their environment.
