Slub fabric is more commonly used for the summer season than for winter. Cotton, polyester, and cotton blends are the usual fibers used for making slub fabrics. Slub knit fabrics are made into tank tops and shirts, light and airy garments perfect for the summer. But you can also use slub fabric in the winter in the form of sweaters and socks. Slub knit fabric has become so popular for making shirts because of the knobbles and the slight lumps in the fabric that gives a more natural look to your clothing. The irregular texture makes it look more interesting than the ordinary cotton or polyester fabric. The most common garment made of slub knit fabric is a shirt. You can also see this textile in sweatshirts, sweatpants, shirt dresses, pajamas, and other casual clothing. The visual effect of the slub knit is not its only advantage but its breathability and lightweight properties, which are essential for the summer season. The uneven texture of this material is an advantage because there is no need to iron the fabric. Your shirt is ready to wear after washing and drying. There are also slub fabrics made of wool or fleece for heavier slub fabrics that you can layer with your winter clothing.
