What does "40s" mean in fabric? In the textile industry, "40s" refers to the yarn count, which indicates the thickness and weight of the yarn used to make the fabric. A 40s yarn count means the yarn is relatively fine, leading to a lightweight and smooth fabric, often used in high-quality garments like shirts and blouses.
Understanding Yarn Count in Fabrics
What is Yarn Count?
Yarn count is a numerical expression that denotes the thickness or fineness of yarn. It is crucial in determining the texture, weight, and quality of the fabric. The yarn count system can vary, but in the context of "40s," it typically refers to the English count system, where higher numbers indicate finer yarn.
- 40s Yarn: A fine yarn that results in lightweight, soft, and breathable fabrics.
- 20s Yarn: A thicker yarn, producing heavier and more durable fabrics.
How is Yarn Count Measured?
Yarn count is measured by the length of yarn needed to weigh one pound. In the English count system, a 40s yarn means that 40 hanks (each 840 yards) weigh one pound. This system helps manufacturers and consumers understand the fabric’s characteristics.

People Also Ask
What is the difference between 40s and 60s yarn?
The primary difference between 40s and 60s yarn is the fineness. A 60s yarn is finer than a 40s yarn, resulting in an even lighter and softer fabric. This makes 60s yarn ideal for luxury garments and high-thread-count bed linens.
How does yarn count affect fabric quality?
Yarn count directly impacts fabric quality by influencing its texture, weight, and durability. Higher yarn counts (like 40s or 60s) typically lead to softer, lighter, and more breathable fabrics, while lower counts are thicker and more robust.
Are 40s yarn fabrics suitable for winter wear?
While 40s yarn fabrics are lightweight and breathable, they are not typically suited for winter wear unless layered with warmer materials. They are best for summer clothing or as a base layer in cooler weather.
What is the best yarn count for bed sheets?
For bed sheets, a yarn count of 40s to 60s is often preferred due to the soft and breathable qualities these counts offer. Higher yarn counts can enhance comfort and luxury, making them a popular choice for premium bedding.
How do I care for 40s yarn fabrics?
To maintain their quality, 40s yarn fabrics should be washed in cold water with a gentle detergent. Avoid high heat when drying to prevent shrinkage and maintain fabric integrity.
