HECOL 370 - QUALITY ASSURANCE FOR TEXTILES & APPAREL
TOPIC 1 - QUALITY
Quality
everyone has their own idea of quality
difficult to express in concrete form
elusive property of an item - product has a certain “something” that makes it better than
competing products, can be not just textiles
to produce a quality product, a manufacturer needs a definition against which they can measure
their products, different for different manufacturers and what they want to achieve
designing a quality product is a complex process, particularly a textile product
must consider all variables that go into making the product
•have to start with the fibre
•when considering natural fibres need to think of the conditions - moisture, insects, which
affects the yarn quality and fabric quality
•raw material —> construction of finished product (sewing) and all steps in between
additionally, must consider consumers’ needs and expectations
quality is a concern at all stages of the “Textile Industry Complex”
The Textile Industry Complex (Kadolph, 2007)
producers of materials
fibres yarns dyes/pigments
finishes fabrics closures, trims, and support materials
producers of products
manufacturers
contractors - might do finishing
distributors of products
wholesalers
retailers - store and non-store formats
consumers of products
Definitions of Quality
1. transcendent (holistic)
meaning most people associate with quality
implies product has an elusive or intangible something that makes it superior to competing
products
quality is not defined in a way that allows for quality management (so not a useful definition for
quality assurance). not useful for manufacturers trying to establish quality control
2. product based (focus of HECOL 370)
quality viewed as a ‘quantifiable attribute’ of a product based on performance in testing
e.g. smoothness, strength, etc.
quality can be determined objectively
3. user based
highest quality products are those best able to satisfy customers’ preferences
drawback for producer - difficult to aggregate wide range of customer preferences into products
with sufficiently wide appeal

HECOL 370 - QUALITY ASSURANCE FOR TEXTILES & APPAREL
think of young children as example - children bed sheets, usually have cartoon or toy product
image on them, if the right character is on the bed sheet that is the top quality product for them
need to have strong consumer studies and research
4. manufacturing based
concerned with manufacturing practices based on conformance to requirements or
specifications - things that can be measured
deviation in manufacturing process from specifications implies reduction in quality
can measure deviation from the procedure and level of quality
excellence is set by standards of the business or organization - might also be outside
organizations that evaluate the product or outside procedure the quality reaches
5. value based (‘best buy’)
quality defined in terms of cost relative to product attributes
assumes consumers’ decisions to buy will be based on quality relative to price - common for
people to buy based on price
‘best buy’ not necessarily the lowest price or the highest quality, but product that offers the nest
combination of the two - some sort of compromise between the two
better bang for your buck
Types of Quality
quality encompasses many steps int he process of producing a quality product for the market
1. quality of design
is a measure of the excellence of the design relative to the customer’s requirements
important 1st step in production of quality product - before anything is made there needs to be a
concept of what the product will be
to ensure functioning of a product throughout its lifetime, quality design must include
specifications for materials, construction and manufacturing processes
tells them what kind of fibres, what kind of yarn, how to set up the knitting machine
2. quality of conformance
measure of product’s compliance with the requirements/ specifications of the initial design
realm of textile testing
3. quality of use
measure of extent to which the user is able to secure continuity of use from the product (length
of the time it lasts)
for textile products the length of time can be quite short compared to household appliances,
cars, etc.
4. quality of customer service
measure of factors such as speed of response to orders, response to customer returns and
complaints, and initial availability of the product
buyers and sellers in the textile complex are really interest in the speed or response - affects
people in the next levels of the complex
