Best yarn for sweaters
How to Choose the Best Yarn for Sweaters.
There is no single best yarn, only the right one for your market, price and product. Here are the three yarn families we knit most, how we handle pilling, shrinkage, softness and colour fastness, and which certified yarns are available.

There is no single best yarn
The right yarn matches product, customer and price.
Performance
Pilling expectations, recovery, care and dimensional stability matter after purchase.
Commercial fit
Composition, count, colour process and availability must work with the target price and volume.
Yarn and stitch shape the result: brushed, cable, waffle and tweed-effect knits from our collections.
Our most-used yarns
The three yarn families we knit most.
Most of the sweaters we make use one of these three families. Each has a clear place in the market.
| Yarn | Price level | Typical markets | Hand-feel and use | Watch out for |
|---|---|---|---|---|
| Cotton–acrylic blend (2/26Nm combed cotton with acrylic) | Value; volume programmes | Cross-border e-commerce, South America, Southeast Asia | Dry, easy-care handle; spring and autumn basics and simple jacquards | Ordinary hand-feel; premium brands rarely use it |
| Wool blends (10–30% wool with acrylic or nylon) | Mid-market mainstay | Fast-fashion womenswear in Europe, Australia and North America | Soft and warm; the most common choice for jacquard and Fair Isle styles | A good balance of pilling performance and cost |
| Cashmere and high-cashmere blends (100% cashmere or cashmere with wool) | Premium | Premium and designer brands in Europe and North America | Very soft and light; winter premium styles, usually simple 2–3 colour double jacquard | Higher cost; demanding knitting, washing and finishing |
Also available: RWS-certified merino wool, an upper mid-market option with traceability, popular with sustainability-focused brands in Europe and North America.
What buyers ask most
Pilling, shrinkage, softness and colour: how we handle them.
These are the four questions we hear most often about yarn. None has a magic answer, but each can be controlled and tested before bulk.
Will it pill?
Wool and cashmere pill naturally, and no knitwear is completely pill-free. We reduce pilling with singed and plied yarns, the right stitch density, and soft milling with an anti-pilling finish, and we consistently reach pilling grade 3–4. Agree the test method, for example the IWS pilling test, and the target grade before bulk.
Will it shrink?
We pre-shrink garments with a relaxed wash, so shrinkage is released during development rather than in your customer’s washing machine. The washing method, such as cold hand wash or gentle machine wash, is fixed on the tech sheet and printed on the care label. For jacquards, we test each yarn colour separately, so the pattern does not twist after washing.
Can it be softer?
Softeners and silicone finishes make a knit softer, but there is a balance: a very strong softener can slightly reduce colour fastness. We adjust the finish to reach the hand-feel you want without trading away performance.
Will the colour run?
Dark yarns are colour-fixed before knitting. For jacquards that combine dark and light colours, we test staining in particular, following AATCC methods, and start bulk only when the results pass.
Colour and testing
Colour behaves differently on every yarn.
Sweater yarn is dyed before it is knitted, so colour has to be right before production starts. Three things often catch buyers out:
- Different fibres, different shades. The same Pantone reference can come out differently on cashmere, cotton and nylon. When several yarns sit side by side in one design, approve lab dips on each actual yarn.
- Sample lot versus bulk lot. Samples are often knitted from a small dye lot and bulk from a larger one. Check the bulk lot against the approved colour before knitting.
- Unwritten tolerance. Agree a colour tolerance, for example grey scale grade 4 or 3.5, rather than a verbal “close enough”.
Tests to agree before bulk
- Pilling grade, especially when different yarns are knitted together
- Colour fastness, so dark colours do not bleed into light areas
- Shrinkage and dimensional stability after the agreed washing method
- Snagging, for patterns with floats on the back
Certified yarns
Recycled, responsible and organic yarns.
- GRS recycled yarns. Recycled polyester, recycled cotton and recycled acrylic. We can provide GRS certificates, and a GRS transaction certificate (TC) can be applied for each order. Many European brands and cross-border sellers require one for customs and traceability. TCs are arranged through the yarn mill and take time, so mention it when you ask for a quote.
- RWS wool. Responsible Wool Standard merino with certification and traceability, focused on animal welfare.
- Organic cotton. OCS and GOTS organic cotton yarns can be arranged.
Certified and dyed-to-order yarns usually come with a yarn mill minimum, often 25–100 kg per lot, which can affect your order quantity. Our MOQ guide explains how.

Questions for a supplier
Ask for project-specific evidence.
A useful yarn discussion ends with an agreed composition, count, colour route, gauge and supporting information for the actual material selected.
AvailabilityIs the yarn in stock, made to order or subject to a supplier minimum?
ColourCan the target colour be achieved within the timing and quantity?
PerformanceWhich testing or care information is relevant to the end market?
SubstitutionWhat changes in hand-feel, appearance and cost if an alternative is required?
