Everything You Need to Know About Knit Fabric

Knit fabric has been a cornerstone of the textile industry for centuries. Its versatility, comfort, and adaptability make it a favorite for both fashion designers and consumers alike. However, do we know enough about this fabric yet? Well, let us discuss the various types of knit fabric here along with its features.

What is Knit Fabric?

At its core, knit fabric is constructed from interlocking loops of yarn. Unlike woven fabrics, where threads are interlaced at right angles, knit fabrics are produced by a series of connected loops. This unique construction gives knit its distinct stretch and flexibility, making it perfect for a wide range of garments, from cozy sweaters to form-fitting active wear.

Features of Knit Fabric

• Knit fabric is different from woven fabric in several ways due to its unique construction method. Understanding these features is crucial for anyone working with or wearing knit fabrics, as they influence the fabric's performance, appearance, and suitability for various applications.  Here are the primary features of knit fabric:
• Elasticity: One of the most defining features of knit fabric is its elasticity. The interlocking loops allow the fabric to stretch and return to its original shape, making it ideal for garments that need to move with the body.
• Drape: Knit fabrics, especially finer knits, have a natural drape, allowing them to flow and conform to the body's contours.
• Breathability: The looped structure of knit fabrics often results in a porous surface, making them breathable. This makes knit garments comfortable to wear in various climates.
• Warmth: Certain knit fabrics, like woolen knits, have insulating properties that trap air, providing warmth. This is why knits are often used for sweaters and winter wear.
• Resilience: Knit fabrics can recover from wrinkles and creases more easily than many woven fabrics. This resilience is due to the looped structure's ability to bounce back.
• Versatility: Knit fabrics can be made from various fibers, from natural ones like cotton and wool to synthetic ones like polyester and nylon. This versatility means there is a knit fabric for almost every purpose.
• Comfort: The softness and stretch of knit fabrics make them exceptionally comfortable to wear. They can accommodate movement without constraining the body.
• Durability: While knits are generally durable, they can be prone to issues like pilling or snagging, especially in certain types of knit constructions or fiber choices.
• Weight variability: Knit fabrics can range from very lightweight, like jersey knits to much heavier varieties, like double knits or cable knits.
• Edge curling: A common characteristic of some knit fabrics, especially jersey, is that the edges tend to curl. This is due to the structure of the loops and how tension is distributed in the fabric.
• Texture variety: From the smooth surface of jersey knit to the textured surface of rib or cable knits, knit fabrics offer a wide range of tactile experiences.

Exploring the Types of Knit Fabric

While we talk about this fabric, we must discuss the various types of this knit fabric that you can come across. Here we mention some of them:

1. Jersey Knit: The everyday hero of knit fabrics, Jersey knit is characterized by its soft touch and inherent stretch. Commonly chosen for T-shirts and lightweight tops, it boasts a smooth exterior and a looped interior. Its drape and breathability make it a summer wardrobe staple.
2. Rib Knit: With its pronounced vertical ridges, rib knit offers elasticity par excellence. It is the go-to choice for garment sections that need to retain their shape after stretching, such as cuffs, collars, and sweater hems. Its symmetrical pattern means it looks the same on both sides, adding to its appeal.
3. Interlock Knit: Think of interlock knit as the refined cousin of rib knit. It offers a smooth texture on both sides, eliminating the looped back typical of the jersey. Its tightness provides a touch more structure, making it a favorite for baby clothes and high-quality apparel.
4. Purl Knit: A textured delight, purl knit alternates between knit and purl stitches. This results in a fabric that is visually rich and feels plush to the touch. Its inherent elasticity and texture make it a preferred choice for scarves, hats, and cozy sweaters.
5. Double Knit: A powerhouse in the knit family, double knit employs two layers of stitches, rendering it both weighty and stable. Its heft makes it a prime candidate for structured garments, such as form-fitting dresses, blazers, and tailored pants.
6. French Terry: The comfort king, French terry is recognized by its looped back and soft exterior. Its absorbent nature makes it a top pick for loungewear, sweatshirts, and athletic apparel. It offers warmth without weight, ensuring comfort in movement.
