Why a buyer should understand the line

Most fabric problems a buyer meets are decided before the cloth is finished. A yarn that drifts in count cannot be corrected by finishing; a weave set too loose cannot be tightened later. Knowing the five stages of woven production tells you where to put your questions — and where two mills that quote the same headline number are actually different.

Stage 1 — Yarn preparation

Production starts with yarn. For cotton and blends, fibre is opened, blended, then carded (and combed if a smoother, more even yarn is wanted). For synthetics, chips are melted and extruded as filament or cut to staple. The yarn count (e.g. 32s, 40s, 60s on the English cotton system) and evenness are fixed here — and evenness is what decides whether a finished cloth shows streaks after dyeing.

Before weaving, warp yarns are wound onto a beam and drawn through the heddles and reed (warping / drawing-in). The warp is also sized — coated with a protective, starch-like substance — so it survives the friction of the loom. Sizing is later washed out; this is the "desizing" step you will see after weaving.

Stage 2 — Weaving the greige cloth

On the loom a continuous cycle repeats: the warp is lifted to open a shed, the weft is picked across, and the reed beats it into place. Thousands of these cycles run per minute on modern looms. The result is greige fabric — the undyed cloth — which is inspected for defects such as broken yarns, slubs and irregular pick spacing before it moves on.

Loom type shapes cost and what can be made well: air-jet looms are fast and economical for plain and simple twill; rapier looms handle a wider range of yarns and more complex structures; water-jet looms are fast but limited to synthetics. Asking a supplier which looms they run tells you what they can produce reliably.

Stage 3 — Dyeing and printing

Colour enters the cloth in one of two places. In piece dyeing, the greige cloth is dyed after weaving — fast and economical for solid colours. In yarn dyeing, the yarn is dyed before weaving, which is what lets a check or stripe survive washing. (We cover the trade-offs in our yarn-dyed vs piece-dyed guide.) Printing then applies a design onto the surface of the finished cloth.

Before dyeing, the cloth is desized and scoured — the sizing is washed out and natural oils, waxes and impurities removed — so the colour takes evenly.

Stage 4 — Finishing

Finishing is where much of the added value appears, and it splits into two families:

Two cloths that look identical on a screen can feel completely different because of finishing — which is exactly why you should ask what was applied before approving a sample.

Stage 5 — Inspection and packing

The finished roll is graded, measured, tested against the agreed standards (weight, strength, shrinkage, colour fastness, pilling) and packed, with a report issued before shipment. This is the checkpoint that turns the earlier stages into a documented, repeatable product. See how we grade rolls in our 4-point inspection guide.

How we handle it

Our line is an integrated woven mill: yarn dyeing, weaving, fabric (piece) dyeing, printing and finishing sit on one site. Raw yarn is sourced and, where the design calls for it, dyed in-house before weaving; the woven cloth is then piece-dyed or printed and finished without a second supplier in the chain. Because the stages are under one roof, a development can move between yarn-dyed and piece-dyed routes, and a fault introduced early is caught before it reaches your cutting room.

Common questions

Does every fabric go through all five stages?

In practice, yes for a woven textile, though some steps are lighter than others. A solid-colour cloth may skip yarn dyeing and go straight to piece dyeing; a greige that is sold unfinished skips finishing. The five-stage map is the default route, and knowing which steps a supplier actually runs tells you where their quality control lives.

What exactly is greige fabric?

Greige (or grey) fabric is the cloth as it comes off the loom — undyed and unfinished. It is the starting point for piece dyeing and most finishing. Its inspection for broken yarns, slubs and pick spacing is the first quality gate before colour is added.

Why does an integrated mill matter to a buyer?

When yarn dyeing, weaving, dyeing, printing and finishing are under one roof, a fault introduced early is caught before it becomes your cutting-room problem, and a development can move between routes without a second supplier. It shortens the loop between a question and an answer.

Can I specify yarn count and construction?

Yes. Yarn count and evenness are set at the spinning/preparation stage and cannot be corrected later, so they belong in your specification from the start. Tell us the count, weave and density you need and we will build the cloth to it — exact achievable figures are confirmed in writing at enquiry.
