How is the quality of a textile item checked and tested, both as it is made and once it is finished?
Quality and testing of textile items: quality control during making (accuracy, consistency, tolerances), objective performance tests (strength, abrasion, colourfastness, shrinkage, flammability), and quality standards and symbols, and why quality matters.
An SQA Higher Fashion and Textile Technology answer on quality and testing, covering quality control during making, objective performance tests such as strength, abrasion, colourfastness, shrinkage and flammability, quality standards and symbols, and why quality matters.

What this key area is asking
A textile item must be well made and reliable, so SQA Higher expects you to understand how quality is controlled and tested - through quality control during making, objective performance tests on the fabric and product, and recognised quality standards and symbols - and why quality matters. This links closely to evaluation (testing the finished item against the specification) and supports the accurate, consistent working assessed in the practical activity. Marks come from naming a test, saying what it checks, and explaining why quality matters.
Quality control during making
Checking as you go - measuring, pressing, testing seams - means a problem (a wrong size, a puckered seam) is fixed at once, not discovered when the item is finished and harder to repair.
Objective performance tests
Finished fabrics and products are tested with objective, measurable tests:
- Strength test - pulls the fabric or seam until it fails, checking it is strong enough for its use.
- Abrasion test - rubs the fabric repeatedly to check resistance to wear and pilling.
- Colourfastness test - washes or rubs the fabric to check the colour does not run or fade.
- Shrinkage test - washes and measures the fabric to confirm it does not shrink beyond tolerance.
- Flammability test - checks how readily the fabric ignites and burns, essential for nightwear, childrenswear and furnishings.
- Water-resistance test - checks how well a fabric resists water passing through, for outerwear.
These give evidence independent of opinion, which is why they are used in industry and in evaluation.
Quality standards and symbols
Recognised quality standards and symbols independently certify a product:
- A kitemark or a British Standard (BS) / ISO mark shows the item meets a recognised standard for quality or safety.
- Safety standards (for example for nightwear flammability or furniture fire safety) must be met by law.
A standard reassures the consumer that an independent body has checked the product.
Why quality matters
Quality matters because poor quality can be unsafe (a flammable garment, a failing seam), damages reputation and customer trust, causes returns, complaints and waste, and means the item does not do its job. Good quality builds loyalty, justifies the price and reduces waste - so quality control and testing are central to a successful product (and to sustainability, since a durable item lasts longer).
Examples in context
Example 1. Abrasion-testing upholstery fabric. A sofa fabric is abrasion-tested (rubbed many thousands of times) to prove it will not wear out or pill in years of use. The measurable rub count gives buyers hard evidence of durability, which is why furnishing fabrics are sold with an abrasion rating.
Example 2. A kitemark on safety equipment. A high-visibility work vest carries a recognised standard mark confirming it meets the required visibility and safety standard. The independent certification reassures employers and workers that the product has been tested to a trusted standard, showing how quality symbols build confidence.
Try this
Q1. State two objective tests carried out on textiles and what each checks. [2 marks]
- Cue. Strength test (the fabric or seam is strong enough); abrasion test (resistance to wear and pilling); colourfastness test (the colour does not run or fade); shrinkage test (no shrinking beyond tolerance); flammability test (how readily it burns) - any two with what they check.
Q2. Explain two reasons quality matters for a textile product. [4 marks]
- Cue. Safety (a flammable or failing item can harm the user); reputation and customer trust (good quality builds loyalty and repeat sales); fewer returns, complaints and waste (cutting cost); the item does its job and lasts, supporting sustainability. Develop any two.

Worth 6 marks. Describe objective tests used on textiles, one mark each for a developed point.
Strength test (1 mark): pulls the fabric or seam until it fails, to check it is strong enough for its use.
Abrasion test (1 mark): rubs the fabric repeatedly to check how well it resists wear and pilling.
Colourfastness test (1 mark): washes or rubs the fabric to check the colour does not run or fade.
Shrinkage test (1 mark): washes and measures the fabric to check it does not shrink beyond tolerance.
Flammability test (1 mark): checks how readily the fabric ignites and burns, vital for nightwear and furnishings.
Water resistance test (1 mark): checks how well a fabric resists water passing through, for outerwear.
SQA Higher style4 marksQuality control during makingShow worked answer →
Worth 4 marks. Explain how quality is controlled during making, linking action to benefit.
Checking accuracy against the pattern and measurements as you work (1 mark) catches errors early, so pieces fit together and the item is the right size (1 mark).
Working to tolerances and checking consistency, for example even seam allowances and matching stitching (1 mark), means every part and every unit meets the standard, so the finished item is reliable and well made (1 mark).
