Hey there! As a supplier of interlock fabric, I've been getting a lot of questions lately about the common fiber contents of this amazing fabric. So, I thought I'd take a moment to break it down for you.
First off, let's talk about what interlock fabric is. It's a double-knit fabric that has a smooth, flat surface on both sides. It's known for its stretch, durability, and ability to hold its shape well. This makes it a popular choice for a variety of clothing items, from t-shirts and polo shirts to underwear and sleepwear.
Now, onto the fiber contents. There are several types of fibers that are commonly used in interlock fabric, each with its own unique properties and benefits.
Cotton
Cotton is one of the most popular fibers used in interlock fabric, and for good reason. It's soft, breathable, and hypoallergenic, making it a great choice for people with sensitive skin. Cotton interlock fabric is also absorbent, which means it can wick away moisture from the body, keeping you cool and dry.

Polyester
Polyester is another common fiber used in interlock fabric. It's strong, lightweight, and resistant to wrinkles and shrinking. Polyester interlock fabric is also quick-drying, which makes it a great choice for athletic wear and outdoor clothing.
One of the benefits of using polyester in interlock fabric is that it can be blended with other fibers, such as cotton, to create a fabric that combines the best properties of both. For example, a cotton-polyester blend interlock fabric will be soft and breathable like cotton, but also strong and wrinkle-resistant like polyester.
Rayon
Rayon is a semi-synthetic fiber that is made from wood pulp. It has a soft, silky feel and drapes well, making it a popular choice for clothing items that require a lot of movement, such as dresses and blouses. Rayon interlock fabric is also absorbent and breathable, which makes it comfortable to wear in warm weather.
However, rayon does have some drawbacks. It can shrink and stretch easily, and it's not as durable as some other fibers. That's why it's often blended with other fibers, such as cotton or polyester, to improve its strength and stability.
Spandex
Spandex, also known as Lycra or elastane, is a synthetic fiber that is known for its stretch and recovery properties. It can stretch up to 500% of its original length and then return to its original shape without losing its elasticity. This makes it a great choice for clothing items that require a lot of stretch, such as leggings, swimwear, and athletic wear.
When spandex is blended with other fibers, such as cotton or polyester, it can add stretch and comfort to the fabric without sacrificing its durability or breathability. For example, a cotton-spandex blend interlock fabric will be soft and breathable like cotton, but also stretchy and comfortable like spandex.
CVC (Cotton/Polyester Blend)
CVC, or cotton/polyester blend, is a popular choice for interlock fabric. It combines the softness and breathability of cotton with the strength and wrinkle resistance of polyester. CVC interlock fabric is often used in polo shirts, as it provides a professional look while still being comfortable to wear.

Collar and Cuff Interlock
Collar and cuff interlock is a special type of interlock fabric that is used specifically for collars and cuffs. It's usually made from a blend of cotton and polyester, which gives it the strength and durability needed to hold its shape, while still being soft and comfortable to wear.
Our Collar and Cuff Interlock is designed to provide a clean, professional look for your clothing items. It's available in a range of colors and weights, so you can find the perfect one for your project.
