Slub knit is a fabric made with yarn that produces an uneven texture. The yarn used to make the fabric has rough places that are thicker than the rest, called slubs. These slubs create an irregular texture when the yarn is made into fabric.
Slubs were a sort of a nuisance to an otherwise perfect fabric. But it has been gaining popularity, especially when the fabric is made into casual clothing. it is a great alternative if you lack wool for knitting. The slubs are now made intentionally to create a heathered look and texture on the fabric.
There was a time when fiber was spun into yarn by hand and then woven into fabric. During weaving, some parts of the yarn become thicker than the rest. These so-called slubs were undesirable and were usually removed and thrown away.
When a machine can do the fiber spinning, the slubs were intentionally included in the fabric. Instead of looking imperfect, they added dimension and personality to an otherwise plain fabric.
Using a machine for spinning can also create equally spaced slubs that are less messy and look more pleasing to the eyes than using the handspun yarns.
The textured fabric became desirable and popular because of its unique look, making it more attractive than plain knit fabric.

What kind of fabric is slub?
A piece of slub fabric is made from yarn without uniform thickness. Some parts of the fabric are thicker than the rest and create a heathered look due to the slubs.
You may have seen this unique type of fabric many times but have no idea what it is called and what its properties are. To know more about this fascinating fabric, here are some of slub fabric’s characteristics.
Many people assume that slub fabric is only made from cotton. Initially, slub fabric was only produced from pure cotton when cotton was the most accessible fiber. These days, many slub knits are still made of cotton and cotton blends.
Slub knit is also made from other natural materials like linen, wool, and silk. But these materials are not ideal for clothing and are rarely slub knit. Most slub fabric manufacturers prefer cotton or cotton blends to make garments because it is the less expensive option.
Synthetic fibers are also used to make slubs. Unlike natural fibers, which are less uniform, they are smooth and even. The use of modern machinery can help add more fibers to create slubs. Polyester seemingly matches the production and demand for cotton slubs among synthetic fibers.
Slub knits have higher production costs than normal fabrics and more so if you use synthetic fibers. To offset the cost of production, polyester or another synthetic fiber is combined with cotton to produce a more reasonably priced slub fabric.
Acrylic cotton, poly-cotton, and elastane cotton are examples of these cotton blends available in the market.
You can also find woolen slub fabric, which is best woven and is excellent for making winter clothing.
Weight and Thickness
The thickness of a slub knit fabric is based on the slub yarn’s weight. You can find thin fabrics with a nice drape that you can use to make a scarf or a dress. Heavy and thick fabrics are also available to make warmer clothing for the cold seasons.

Slub knit fabric is generally stretchy because of the construction of the fabric. Knits are stretchier than woven fabrics because the parallel threads and loops give the fabric more stretch horizontally. The slubs do not have much effect on the stretchiness of the fabric.
The stretchiness of a slub knit fabric also depends on the fiber used. Natural fibers like cotton are stretchier than synthetic fibers like polyester or acrylic.
So, if your slub knit is made of poly-cotton, expect it to be less stretched than a pure cotton one. On the other hand, Elastane is a stretchy fabric and will have more give when combined with cotton.
