Why the chain is long
A garment is rarely made in one place by one company. It is the end of a chain of steps, each handled by specialists: growing or producing the fiber, turning it into yarn, turning yarn into fabric, coloring and finishing the fabric, cutting and sewing, and finally distribution to shops. The chain is sometimes called a supply chain, and sometimes a value chain, because each step adds cost and value.
Different businesses specialize in different stages, and they are located wherever the combination of skills, equipment, costs and trade conditions suits them. That is why one shirt can involve fiber from one country, fabric from another and sewing in a third.
The sections below follow two well-known natural fibers, cotton and wool, through the usual stages. Practices vary, so treat this as a general outline.
Stage 1: Raw material
Cotton is grown as a crop on farms in warm regions. The plant produces bolls, which hold fibers around the seeds. After harvest, which may be done by hand or machine, the cotton goes to a gin, where seeds and debris are separated from the fiber. The fiber is pressed into bales for sale.
Wool comes from sheep. Shearing, typically once a year, removes the fleece. The fleece is sorted by quality and then cleaned, or scoured, to remove grease, dirt and plant matter. Fleece quality is graded, with finer fibers generally used for softer garments. The qualities of different wool types are covered in wool garments.
Man-made fibers follow a different first stage. Synthetic types start from chemical raw materials that are processed into filaments, as outlined in synthetic fibers. Other man-made fibers start from plant material such as wood pulp that is chemically processed.
Stage 2: Spinning
Fibers are cleaned, aligned and drawn out into a loose strand, then twisted into yarn. The way this is done affects the yarn’s smoothness, strength and softness. For wool, there are broad families of yarn making that give different results, for example smoother and tighter yarn versus fluffier and more textured yarn. Yarn is wound onto cones or spools for the next step.
Stage 3: Fabric making
Yarn becomes fabric in two main ways:
- Weaving, which interlaces two sets of threads at right angles on a loom, producing stable cloth.
- Knitting, which forms interlocking loops, producing stretchier cloth.
The difference matters for how a garment fits and hangs, which is the subject of knit versus woven. Fabric produced at this stage is usually unfinished and is sometimes called greige goods when it is not yet dyed or treated.
Stage 4: Dyeing, printing and finishing
Cloth is then cleaned and given color, either by dyeing yarn before it is woven or knitted, dyeing the whole piece of fabric, or printing patterns on the surface. Finishing treatments can soften the fabric, make it more wrinkle-resistant, change its feel or add water resistance. Historical and modern coloring methods are discussed in natural dyes.
This stage uses substantial amounts of water, energy and chemicals, and so it features strongly in discussions about the environmental impact of clothing. Regulation and practice differ by location, and the picture is mixed.
Stage 5: Cut and sew
Fabric is delivered to a garment factory, where it is cut and sewn according to the approved pattern and sample, as outlined in clothing production. Trims such as zippers, buttons, thread and labels, which come from their own supply chains, are added. The finished items are inspected, labeled and packed.
Many factories do not own the brands they make for. A brand often contracts with a manufacturer, sometimes through an agent or intermediary, and the manufacturer may in turn use subcontractors for parts of the work, such as embroidery or washing.
Stage 6: Distribution and retail
Packed garments are transported by sea, air, rail or road to warehouses and then to stores or directly to customers. Shipping method influences both cost and time. Faster options usually cost more and typically have a higher environmental impact per item, though the exact comparison depends on many factors.
Why the structure matters
Lead times. Each step takes time, and orders for fabric are often placed long before a collection is final. This is part of why seasons are planned so far in advance.
Traceability. The further back in the chain you go, the harder it is for a brand to know exactly where something came from. A company may know its final factory well but have little information about the farm or mill that supplied the fiber. This is one reason origin claims on labels should be read with care, and why certification schemes exist.
Cost. Price reflects every stage, not just the sewing. Fiber quality, mill processes, dyeing, labor, shipping and retail margins all contribute. The factors behind why clothing prices vary go beyond the visible garment.
Responsibility. Concerns about working conditions, wages, chemical use and land use arise at different stages. Businesses, workers, governments, certification bodies and shoppers all have roles, and views differ about where responsibility should lie.
Resilience. A long chain with many links can be disrupted by weather, trade changes or transport problems at any stage, and these disruptions may affect availability and price.
Shorter chains
Some makers shorten the chain by working with local mills, using deadstock fabric left over from other producers, or producing in small batches. Others use recycled fibers. Shorter does not automatically mean better, since a local process can still be wasteful, but it can make information easier to obtain. A shopper who is curious can look for brands that explain their production stages in specific terms rather than general slogans.
