When you’re choosing a knit for your sewing project do you know which type of fiber is good for that garment?

Fiber type can greatly effect how your garment turns out, lets talk about these top 3 and learn what they are useful for

Cotton Knit

Cotton is known for being breathable, absorbent, and quick drying. It’s fairly strong fiber.

For these reasons it’s commonly used in all daily wear. T-shirts, dresses, leggings, pullovers, sweats and so much more. 

It is important to note that cotton tends to bag out over time, meaning that with your body heat it will stretch out over time. Sweat also tends to degrade the fibers faster and its absorbency makes it heavier when wet. Meaning it is not ideal for super tight fitting athletic wear.

Spandex Knit

Spandex, also known as elastase, or Lycra, is well known for being incredibly elastic without using its shape. 

We use spandex a lot in any high stretch active wear like leggings and leotards

However heat can damage this fiber meaning that friction can have a negative effect so it’s commonly blended with other stronger fibers. Spandex is not very breathable and isn’t absorbent. For all of these reasons it’s common to see spandex and cotton blended together to balance out both of the fabrics weaknesses. 

If you’re looking at sustainable fabrics it’s best to note that blended fibers are harder to recycle. 

Bamboo Knit

Bamboo and other rayons are soft and breathable but also noted for being anti microbial and thermo regulating. 

For these reasons they are commonly used in casual dresses, tshirts, and other lounge wear.

It’s notable that bamboo is also very prone to pilling so it should be washed inside out. Bamboo is a semisynthetic fiber, though it is often touted as an eco friendly option as opposed to cottons water consumption, creating a rayon involves a lot of chemicals to soften and bind the fibers.

In summary, cotton knits are best for daily lounge wear because it’s absorbent and breathable but you see cotton spandex blends often in sportswear. Spandex is most common in athletic wear since it is so stretchy. Bamboo/ rayon knits are used often for daily casual wear dresses, cardigans, and leggings for their comfort.
