When you’re picking yarn for your next knitting or crochet project, you’ll probably come across two main types: acrylic and natural fiber yarns. 

Some crafters swear by the softness of natural fibers, while others love the durability and affordability of acrylic. But what exactly sets them apart?

If you've ever wondered, "Is acrylic wool?" or "Is acrylic natural or synthetic?", you’re not alone! 

In this guide, we’ll break down the key differences between acrylic and natural yarn fibers, helping you choose the best yarn for your projects.

What is Acrylic Yarn?

Acrylic yarn is one of the most widely used yarns in the crafting world, and there’s a reason for that—it’s budget-friendly, easy to care for, and comes in endless colors and textures.

How is Acrylic Yarn Made?

Unlike natural fibers like wool or cotton, acrylic yarn is completely synthetic. So, to answer the common question, "Is acrylic natural or synthetic?"—it’s 100% synthetic.

Acrylic yarn is created from petroleum-based chemicals that are processed into fibers, spun into threads, and then woven into yarn. This process gives acrylic its smooth, often shiny texture, and allows for bright, vibrant colors that don’t fade easily.

Why Do People Love Acrylic Yarn?

Many crafters choose acrylic yarn because it’s affordable, widely available, and comes in a massive variety of colors and textures. It’s also incredibly durable, which makes it perfect for projects that need to withstand frequent washing or daily use. Another advantage is that acrylic yarn is hypoallergenic, making it a great choice for people who are allergic to wool or other animal fibers.

What Are Natural Yarn Fibers?

Natural fiber yarns come straight from nature, either from animals (like wool, alpaca, or silk) or plants (like cotton, bamboo, or linen). These fibers have been used for centuries in textiles and crafting, prized for their softness, durability, and breathability.

Types of Natural Yarn Fibers

Natural yarns come in a variety of types, each with unique qualities. 

• Wool – Soft, warm, and elastic, wool is perfect for cozy winter garments and accessories.

• Cotton – Lightweight and breathable, cotton is great for summer wear and baby blankets.

• Alpaca – Warmer than wool and super soft, but can be pricey.

• Silk – Luxurious, smooth, and naturally shiny, silk is often blended with other fibers.

• Bamboo – A sustainable, silky-smooth plant-based fiber that’s soft and breathable.

Why Do People Love Natural Yarn?

Crafters who love natural yarns often appreciate their softness, breathability, and eco-friendliness. Natural fibers allow air to circulate, making them more comfortable in different climates. They also feel softer and cozier against the skin compared to synthetic yarns. Many people prefer natural yarns because they are biodegradable and come from renewable sources, making them a more sustainable option for environmentally-conscious crafters.

The Main Differences Between Acrylic and Natural Yarn

Now that we know what both types are, let’s compare them side by side!

Texture & Feel

Natural yarns are known for their softness and warmth, while acrylic yarn can sometimes feel a little plasticky. Wool, for example, has a natural elasticity that makes it easy to work with, while cotton is smooth and firm. Acrylic yarn varies in texture—some are soft and fluffy, while others have a slight stiffness to them. Higher-quality acrylic yarns tend to feel softer and more luxurious.

Durability

Acrylic yarn is incredibly durable and resists wear and tear, making it great for items that need to last, like blankets or amigurumi. Natural yarns, while long-lasting, require more care and can sometimes pill or lose shape over time. Wool is naturally resilient, but cotton can shrink if not washed properly.

Breathability & Comfort

If you want something that keeps you warm while still allowing your skin to breathe, natural yarns are the way to go. Wool wicks away moisture, keeping you cozy without overheating, while acrylic traps heat, which can make it feel stuffy in warmer weather. Cotton and bamboo yarns are especially breathable, making them ideal for summer garments.

Care & Maintenance

Acrylic yarn is one of the easiest yarns to care for. It’s machine washable, doesn’t shrink, and holds its color well, making it perfect for everyday items. Natural yarns, on the other hand, often require special care. Wool needs to be hand-washed or washed in cold water to prevent felting, while silk and alpaca need gentle handling to maintain their softness and shape.

Environmental Impact

Natural fibers are biodegradable and come from renewable sources, making them more sustainable than acrylic yarns. Acrylic, being a petroleum-based product, does not break down naturally and contributes to environmental waste. However, some brands are now offering recycled acrylic yarn as a more eco-friendly alternative.

When to Use Acrylic vs. Natural Yarn

Choosing between acrylic and natural yarn depends on your project, budget, and personal preferences.

Best Uses for Acrylic Yarn

Acrylic yarn is perfect for blankets, afghans, and home décor projects since it’s durable and easy to clean. It’s also great for toys and amigurumi because it holds its shape well and doesn’t stretch out. Beginners often choose acrylic yarn because it’s affordable and readily available, making it easy to practice with. If you or someone you’re making something for has a wool allergy, acrylic is a safe alternative.

Best Uses for Natural Yarn

Natural yarns are ideal for garments and accessories since they’re soft, breathable, and comfortable to wear. Wool and alpaca are great for sweaters, scarves, and cozy winter hats, while cotton and bamboo are perfect for lightweight tops and baby blankets. If you’re creating an heirloom-quality piece or something special, natural yarns add a luxurious touch that’s worth the extra care.

Blended Yarns: The Best of Both Worlds

Blended yarns combine the benefits of both acrylic and natural fibers, making them a great choice for those who want the softness of natural fibers with the durability of acrylic. 

Wool-acrylic blends add warmth and elasticity while keeping costs low, while cotton-acrylic blends give a breathable texture with added durability. Silk-acrylic blends maintain the luxurious feel of silk but make it more affordable and easier to care for.

Blended yarns offer versatility, making them ideal for projects that need a balance of softness, strength, and easy maintenance.

Choosing the Right Yarn for Your Projects

So, is acrylic wool? The answer is no—acrylic is a synthetic alternative to wool, designed to be durable, affordable, and easy to care for. And if you’ve been wondering, "Is acrylic natural or synthetic?", it’s completely synthetic, made from petroleum-based fibers.

Choosing between acrylic and natural yarn depends on your project, budget, and personal preference. Acrylic is an excellent all-purpose option that’s easy to maintain, while natural fibers provide superior softness, breathability, and eco-friendliness. If you’re looking for a middle ground, blended yarns offer a fantastic mix of both.

At the end of the day, there’s no right or wrong choice—just what works best for you! 

Try experimenting with different yarns, see how they feel in your hands, and most importantly, have fun with your projects.
