Quick answer

A yarn price is fiber cost plus conversion cost, pushed up or down by the market. Fiber is usually the biggest share, so cotton, polyester and viscose moves come through first, weighted by the blend. Conversion cost depends on the count (finer yarn runs slower and costs more), the spinning system, power, labour and how fully the mill is running. On top of that sits demand. This includes the domestic buying season, export orders and how much stock weavers and spinners are holding. Duties or policy that change the cost of imports and exports also matter. That is why yarn can move even when fiber is flat.

Why yarn prices matter to a fabric buyer

Yarn is the step between fiber and cloth. A spinning mill buys fiber, opens and cleans it, and twists it into yarn on cones. A weaver buys those cones and turns them into greige (unfinished cloth straight off the loom). For most woven fabric, yarn is the single largest input cost, so when a supplier explains a price change, yarn is usually the reason they give.

In the previous lesson you saw what moves cotton, polyester and viscose. This lesson takes the next step down the chain. Fiber is only part of what a spinner charges. The rest is the cost of spinning it and the state of the yarn market on the day. Knowing those pieces lets you judge whether a "yarn is up" explanation makes sense for the fabric you are buying.

The three parts of a yarn price

How a yarn price is builtFiber and conversion set the cost floor. The market decides how far above it yarn sells.Fiber costThe largest shareMoved byFiber price, blend mix,waste lost in cleaningand combing+Conversion costTurning fiber into yarnMoved byCount, spinning system,power, labour, millutilisation+Market pressureWhat buyers will pay todayMoved byDemand season, exportorders, inventory cycles,duties and policy=Yarn priceWhat the weaver paysper kilo of yarn onthe coneYarn can move when fiber does notA power tariff change, a busy season or a rush of export orders shifts yarn on its own, before fiber moves at all.

Think of a yarn price as three blocks. The first is fiber cost: the fiber itself, plus the fiber lost as waste while the mill cleans it. For combed yarn, this also includes the short fibers that combing removes. The second is conversion cost: everything it takes to turn fiber into yarn, such as power, labour, machine time, packing and overheads. Together these two set the floor, the minimum price a spinner cannot go below for long.

The third block is market pressure. When weavers are busy and buying, spinners can price above their floor. When orders are thin and warehouses are full, they cut close to it, and sometimes below it for a while to clear stock. The rest of this lesson walks through each block.

Fiber cost: the biggest share, weighted by the blend

Because fiber makes up most of a yarn's cost, fiber moves pass through to yarn faster and more fully than they pass through to fabric. A spinner buying fresh fiber at a higher price has little room to absorb it.

The blend decides which fiber moves matter. A 65/35 poly-viscose yarn follows mostly polyester prices, but viscose usually costs more per kilo than polyester, so its share of the cost is larger than its share of the weight. A poly-cotton yarn is affected by cotton's crop cycle. A 100 percent polyester spun yarn is barely affected by it. Changing the ratio changes the fiber bill, which is one reason two blends of the same count are priced differently. The ratios lesson shows the common splits, and yarn counts and blends explained shows how they are written.

Waste matters too. Combed cotton loses more fiber in combing than carded cotton does, so the same kilo of finished yarn needs more raw fiber. The combed and carded lesson covers what combing buys you in return.

Count: finer yarn costs more to make

The count tells you how fine a yarn is. On the English cotton count (Ne) system, the higher the number, the finer the yarn. A finer yarn has fewer fibers in its cross section, so it needs better, longer fiber to stay strong. It also needs more twist and more care to spin without breaking.

Fine yarn also comes off the machine slowly. A spindle produces a certain length of yarn per hour, and a finer yarn weighs less per metre, so each spindle turns out fewer kilos in the same time. Power, labour and machine cost are spread over fewer kilos, so the conversion cost per kilo rises as the count gets finer. That is why fine shirting yarn costs more per kilo than a coarser yarn of the same blend, even before fiber quality enters the picture. Ply adds a step as well: a two-ply yarn has to be spun, then doubled and twisted again.

Spinning system, power and labour

Yarn can be spun on different systems. Ring spinning is the traditional method and makes a strong, fine, smooth yarn, but it is the slowest. Open-end (rotor) spinning is much faster and cheaper per kilo but suits coarser counts and gives a bulkier, weaker yarn. Air-jet spinning sits in between for some uses. The system a spinner uses, and any extra steps such as compact spinning or combing, shape the cost of each kilo.

Power is one of the largest conversion costs, because spinning needs a lot of machinery and many mills run day and night. In India, industrial power tariffs are set at state level, so a change in a state's tariff, or in the cost of a mill's own captive power, feeds into yarn costs directly. Labour, maintenance and spare parts make up much of the rest.

Mill utilisation: why a full mill can price better

A spinning mill has heavy fixed costs: machines, buildings, interest on loans and staff who are paid whether the spindles turn or not. Capacity utilisation is the share of that capacity actually running. When a mill runs full, those fixed costs are spread over more kilos and each kilo carries less of them.

This works in both directions for price. A mill running short of orders has a higher cost per kilo, yet it may still sell cheaply to keep machines turning and cash coming in. When most mills in a region run full, spare capacity disappears and spinners can raise prices. Trade press reports on mill utilisation are a useful signal of which way yarn is leaning.

Demand: seasons, exports and inventory cycles

Domestic demand for yarn follows the fabric calendar. Weavers buy ahead of the festive and wedding seasons and ahead of the school uniform cycle, so yarn demand tends to rise before those peaks and ease after them. For uniform buyers, the annual planning guide shows how this calendar affects when to order.

Export demand is the second force. India sells a large amount of yarn abroad, so when overseas buyers order heavily, domestic weavers compete with them for the same output and local prices go up. When export orders slow, that yarn turns back to the home market and prices ease. Currency plays into this: a weaker rupee makes Indian yarn more attractive abroad.

Inventory cycles are the third. When prices are rising, weavers and traders buy ahead to beat the next increase, which adds demand and pushes prices further. When prices start falling, buyers wait for lower levels and run down their own stock, which deepens the fall. These swings can make yarn move more sharply than the underlying fiber.

Duties and policy

Government policy touches yarn at several points. Import duties and anti-dumping duties on fiber, yarn or the raw materials of synthetic fiber change the cost of the imported option and therefore what local spinners can charge. Quality control orders can limit which imported fiber or yarn may be used. Export incentives, and any restrictions on cotton or yarn exports, shift how much yarn stays at home. Changes in tax rates on fiber and yarn also affect what a weaver finally pays. Trade policy can hit yarn without touching fabric, as our note on Vietnam's duty on Indian polyester yarn shows.

These rules change from time to time, sometimes with little notice, so this lesson does not list current rates. For how such shocks are shared in a supply contract, see who pays when duty, freight or fiber costs move.

At Benny Cotts we do not spin. We buy yarn, weave in-house at Village Atoon in Bhilwara, and send greige to partnered Bhilwara process houses for dyeing, processing, finishing and testing. Yarn is the market we feel most directly, so it is the first thing we check when a buyer asks why a price has moved.

What this means when you buy

  • Know your count and blend. A finer count or a viscose-rich blend costs more for real reasons; check both on the spec sheet.
  • Expect yarn to move on its own. Power, season and export demand can shift yarn when fiber headlines are quiet.
  • Order ahead of the peak. Fixing quantities before the busy season lets your supplier buy yarn before demand pushes the price up.
  • Read what a quote assumes. Understanding fabric quotations and uniform fabric pricing explained show how input costs and validity periods fit together.

Next lesson: Yarn quality: what to check, which looks at the yarn properties that matter as much as its price. When you are ready to see the cloth, Request Catalog from our quote page.

FAQ

Frequently asked questions

Why do yarn prices change when fiber prices have not?
Because fiber is only one part of a yarn price. Power costs, mill utilisation, the domestic buying season, export orders and stock building or destocking by weavers can all move yarn while fiber is flat.
Why does a finer yarn cost more?
Finer yarn needs better fiber to stay strong, and each spindle turns out fewer kilos of it per hour. The same power, labour and machine cost is spread over less yarn, so the cost per kilo rises as the count gets finer.
Is open-end yarn cheaper than ring-spun yarn?
Usually, for the same count and fiber, because open-end spinning is much faster. It suits coarser counts and gives a bulkier, weaker yarn, so it cannot simply replace ring-spun yarn. Formal suiting and fine shirting normally use ring-spun yarn.
Do export orders affect the yarn in my fabric?
They can. Spinners sell to both domestic weavers and overseas buyers. Strong export demand reduces the supply left at home and raises local prices. Weak export demand does the opposite.
Does yarn price affect poly-viscose and cotton fabrics differently?
Yes. Poly-viscose yarn follows polyester and viscose fiber costs, while cotton yarn follows the cotton crop. Conversion costs such as power and labour touch both, so a power tariff change moves both, but a monsoon story mostly moves cotton.
