Textile pricing starts with fibers. This page explains how the fiber price guides linked from the Yarn Prices section — cotton, wool, nylon, polyester and silk — help buyers and costing teams judge yarn and fabric prices before they request firm quotations.
Every yarn and fabric price is built upward from fiber cost. A spinner buys cotton, wool, polyester staple, nylon or silk, converts it into yarn, and prices that yarn to cover the fiber, the conversion, and the costs of blending, dyeing and finishing where they apply. When the underlying fiber market rises, yarn prices follow, usually with a lag while existing fiber stocks work through the pipeline; when fiber falls, buyers reasonably expect yarn quotations to soften in turn. That is why this pricing links page is organized by fiber rather than by finished product: the fiber pages are where price movement starts.
The major fibers behave differently, which is why each has its own price guide. Cotton is an agricultural market shaped by harvests, weather and export demand. Wool is sold largely through auction systems and varies sharply by fineness. Polyester and nylon are synthetic markets linked to petrochemical feedstocks and plant capacity. Silk is a small, premium market with its own supply rhythm. A costing that treats these as one generic raw material will miss the actual reason a particular yarn moved, and may accept or reject a quote for the wrong reason.
Pricing links are best used as benchmarks before and during negotiation, not as substitutes for quotations. A typical workflow is to check the relevant fiber price page to establish the market direction, read any market commentary for the reasons behind recent movement, and then compare supplier quotations against that background. If three spinners quote similar increases while the fiber benchmark is flat, the increase probably reflects conversion costs or capacity; if the benchmark has jumped, the quotes are easier to verify and plan around. Either way, the benchmark turns a price discussion from opinion into evidence.
For product costing, fiber benchmarks also protect margins over a season. Apparel is often costed months before delivery, so a costing team that watches fiber prices can flag when a style's yarn cost is likely to move, build sensible allowances into price negotiations with retailers, and time fiber or yarn purchases when markets dip. Historical price pages are useful here as well: knowing the range a fiber has traded in over recent seasons gives a realistic sense of how much movement to allow for, rather than costing everything at today's spot level and hoping it holds.
A benchmark becomes a purchase only through a firm quotation. Published fiber and yarn prices are indicators: they may refer to a standard grade, a particular delivery location, or an average across many transactions, none of which exactly matches your specification. Yarn count, blend ratio, twist, dyeing, package type, quantity and delivery terms all move the real price away from any headline figure. Experienced buyers therefore use pricing links to prepare, then ask suppliers for dated written quotes on the exact specification, valid for a stated period, and compare like with like across at least two or three sources.
Keep records as you go. Note the benchmark level and date alongside each quotation received, the specification quoted, and the validity period, so that later in the season you can reconstruct why a price was accepted. That habit also makes the next costing faster: your own history of fiber benchmarks against actual yarn purchases becomes a private pricing resource more precise than any public page. The fiber price guides linked from this section — cotton, wool, nylon, polyester and silk — remain the public starting point that this page exists to organize.
Textile prices are time-sensitive information, and this page deliberately explains the pricing system rather than quoting figures that would date immediately. Markets move daily, grades differ, and a number copied onto a guide page would mislead readers within weeks. The linked price services and fiber guides are the right places for current figures, because updating prices is their function. What a guide page can usefully provide — and what this one aims to provide — is the map: which fiber markets matter for which yarns, how to read a benchmark, and how to turn public price information into a sound, documented buying decision.

Because fiber is the base cost of every yarn and fabric. Cotton, wool, nylon, polyester and silk each trade in distinct markets with different drivers, so each fiber has its own price guide and its own effect on yarn costing.
Use them as benchmarks and allowances, not final costs. Your costing sheet should ultimately carry a firm supplier quotation for your exact yarn specification, with the benchmark noted as supporting evidence and dated.
Fiber markets can move daily, and yarn quotations typically carry a limited validity period set by the spinner. That is why this guide explains how pricing works and points to live price services instead of printing figures that would quickly go stale.
