Combed vs Carded vs Open-End Yarn: Differences and Uses by Product

Combed, carded and open-end yarn are not on the same axis

According to Cotton Incorporated, cotton yarns are often classified by spinning system: ring, open-end and air-jet (vortex included). Fiber preparation differs somewhat between these systems (ISP 1006). Carding is part of all of them; all cotton and cotton-blend fibers, including those that go into combed yarn, pass through the card first (Cotton Incorporated, Textile Yarns). Combing is a step added after carding. The roving step belongs to ring yarn only; open-end spins directly from sliver.

The two questions are independent:

Combed and open-end are not mutually exclusive. Rowe (1993) describes how rotor yarn quality can be raised with combed cotton sliver; Cotton Incorporated, after giving the economical count range of open-end, adds that finer counts need combing to be spun without defects and weakness (Textile Yarns). There is a link in the other direction too: in Rieter's 2020 study, the waste of the combing line (comber noil) was tried as a raw material for rotor spinning in blend ratios from 0% to 100%; in Rieter's denim weft example the raw material is 70% cotton and 30% noil.

In everyday Turkish trade talk, penye also names a knit fabric; in this guide it is used only for yarn. You may meet two more variants on a quote: compact ring, where a suction unit added to the ring frame makes the yarn tighter, less hairy and stronger; and vortex, a newer type of air-jet spinning that gives a ring-like look and can spin 100% cotton (ISP 1006; Textile Yarns).

Combed vs carded yarn: what does combing change?

Combing removes short fibers, neps and remaining small trash from the sliver that comes off the card, and makes the fibers more parallel; the waste removed is called comber noil (ISP 1006). According to Cotton Incorporated the waste share is 4% to 24%; according to NPTEL (IIT Delhi) it is 8% to 25%, depending on the industry and requirement. Cotton Incorporated's comparison for ring yarn is as follows:

Two consequences of combing stand out in practice. The first is twist: because the fibers are longer, combed yarn reaches similar strength with less twist than carded yarn; that means a softer yarn and fabric and less torque (tendency to twist out of shape). Combed yarn also tends to pill and shed fibers less (Textile Yarns; ISP 1006). The second is the combing level: quality depends on the share of noil removed and on whether the yarn is fully or partly combed. Partly combed yarn is made from a blend of combed and uncombed sliver; for the same input quality, a line that removes 16% noil gives a better yarn than one that removes 10% (Textile Yarns). That is why writing only “combed” on a quote is incomplete information.

Combed is not always necessary or “better”, either. According to NPTEL, in coarse and medium counts combing is an optional process to raise the yarn's cleanliness, smoothness and strength; in fine counts it is essential. The extra process, the waste and the intermittent operation make combed cotton more expensive than carded cotton. The sources do not give the size of the price gap; for a comparison, get written quotes for the same count and the same preparation level.

Open-end vs ring yarn: the spinning-system difference

In ring spinning, fibers leave the drafting system as a continuous, ribbon-like strand and twist is inserted in the yarn. In open-end spinning, fibers are separated one by one from the sliver, collect in the groove of a fast-spinning rotor and are twisted there. Cotton Incorporated sums it up this way: ring yarn forms from the outside in, open-end yarn from the inside out (TRI 1004). In the rotor, some fibers wrap around the yarn instead of being twisted into it; these wrapper fibers do not add to strength and are specific to open-end yarn (ISP 1006).

Source: Cotton Incorporated, ISP 1006 (p. 7), Textile Yarns (pp. 15–16, 20–21) and TRI 1004 (pp. 9–10).

These figures come from bulletins published around 2003 and 2010 and show the general trend. The gap depends on fiber length: according to TRI 1004, with fibers longer than 1-1/8 inch (about 28.6 mm) open-end yarn can be up to 25–30% weaker than ring yarn; as fiber gets shorter the gap shrinks quickly, and at some coarse counts open-end can even be slightly stronger. Open-end tolerates short fibers better; the ring drafting system needs a minimum fiber length to control the fibers (TRI 1004). The handle of open-end yarn also changes with setup: according to ISP 1006, if a more abrasive navel (the part at the yarn exit) is chosen, the yarn becomes softer and bulkier.

In fabric: strength, pilling and abrasion

A yarn difference does not carry into fabric in one direction. Candan and colleagues (2000) compared ring and open-end cotton yarns in plain jersey and lacoste knit fabrics (the abstract's term): fabrics made from open-end yarn had lower bursting strength and more pilling, and ring was slightly better in abrasion resistance. Hailemariam and Muhammed (2024) reported, for 3/1 twill denim woven from Ne 10 cotton yarn, that the ring-yarn fabric was better in tensile and tear strength, and the rotor-yarn fabric in abrasion resistance, pilling resistance and air permeability.

On pilling, the two studies point in opposite directions (ring better in knits, rotor better in woven denim); the fabric type, count and date of the work differ. No general statement such as “open-end always pills more” or the reverse can therefore be made. For a firm decision, knit the target fabric from each yarn and compare them with the same test.

Which yarn for which product? Sourced examples

The sources give no binding table matching products and counts. The rows below summarize examples from the sources; the Rieter rows are brochure examples from a machine maker, not a market standard.

The last row matters: sometimes the yarn type is not a technical preference but a written obligation. As of October 11, 2026, the Bursa Towel rules are in the geographical indication registration text at TÜRKPATENT. If you produce under this indication or a customer specification, check the current text, and if needed consult the registering body (Bursa Ticaret Borsası, the Bursa commodity exchange) or an expert. How to read this decision in towel yarn is covered in terry towel quality; the choice among single jersey, piqué, interlock and rib for T-shirts is covered in T-shirt fabric types. Tekstil Rehberi's starting point is this: if a fine, soft handle is the priority, start with combed ring; if cost and an even surface are the priority, also ask for carded and open-end quotes, and compare the samples with the same test.

How common is open-end spinning in Turkey?

According to ITMF's estimate for the end of 2023, Turkey has about 8.80 million short-staple (ring) spindles, 948,550 rotors and 57,380 air-jet spindles installed; the world total is 231.7 million spindles and 9.71 million rotors (ITMF, International Textile Industry Statistics 66/2023). From these, Turkey holds about 3.8% of the world's spindles and about 9.8% of its rotors; the ratios are Tekstil Rehberi's calculation. Because the productivity of one rotor position is 8–10 times that of a ring spindle (ISP 1006), these ratios are not production shares; ITMF's table does not separate combing lines or yarn counts either. According to ITMF's 2022 shipment data, Turkey, together with China and India, was among the world's three largest rotor investors; Turkey's rotor investment had risen 91% over the previous year (Textile World, June 2023).

How to write the yarn type on a quote or spec

Saying “combed yarn” or “open-end yarn” alone is not enough. The order below is a starting point for writing the different axes separately:

1. Fiber and composition: 100% cotton, cotton-polyester and so on, in percentages.
2. Fiber preparation: carded or combed (penye). For combed, ask whether it is fully or partly combed and the combing level (the percentage of noil removed).
3. Spinning system: ring, compact ring, open-end or vortex.
4. Count and ply: with the name of the system, for example Ne 30/1. Use the yarn count converter if you need to convert.
5. Twist direction: ring yarn can be Z or S twist; open-end is Z twist only (Cotton Incorporated).
6. Quality values: evenness (CVm), yarn imperfections, hairiness and strength. In Uster Statistics the curves are separate by yarn type and count (Rieter, Figure 1); compare reports only for the same type and the same count.

Example line: “100% cotton, Ne 30/1, fully combed (penye) ring yarn, with an evenness, imperfection and hairiness report.” This information may not appear on the product label; ask the supplier in writing. If you need measurements, you can find firms in the textile testing laboratories category.

Summary

Combed and carded differ in fiber preparation, ring and open-end in spinning system; that is why combinations such as carded ring, combed ring and carded open-end exist. Combed yarn is more even, softer and less hairy than carded yarn; open-end yarn is more even, less hairy and cheaper than ring yarn, but weaker and harsher in handle with the same fiber. Which one is right depends on count, fabric, budget and specification together. You can find yarn suppliers in the cotton yarn category.
