Knit Fabric Types: Explore Concept, Types, Process & More

From performance wear to everyday t shirts, and a cozy sweater, today’s textile world is dominated by knit fabrics. As a maker, designer, or buyer, being able to identify different knit fabric types will help you pick the right fabric for comfort, function, and style. In this guide, you’ll learn the definition of knit fabrics, how they’re manufactured, and the characteristics of commonly used types like jersey, rib, and waffle knits. By the end, you will learn how to select, use and care for the very best knit fabric types for any project.

What is Knit Fabric?

Textile made by interlooping yarns to form a series of connected loops is called knit fabric. Knit fabrics are different from woven fabrics, which crisscross yarns over and under each other as they attach together; knit fabrics are made of one or more yarns that form loops in a certain direction. These loops create courses (rows) and wales (columns), thus giving the fabric its distinctive stretch and structure. Knit fabrics are everywhere — from T-shirts and leggings to socks and sweaters.

Step-by-Step Knitted Fabric Manufacturing Process

Fiber to Yarn Conversion

Fiber Preparation

You can choose from natural fibers such as cotton, wool, silk, or synthetics like polyester and spandex. Most natural fibers require cleaning to remove dirt and debris. With synthetics, you will mostly just worry about separating it evenly. Picker helps you to open and clean the fibers to ready them for further processing.

Carding and Web Formation

Then, you run the cleaned fibers through a carding machine. They align into a smooth continuous web. If you want consistent and strong yarn, you must card. The fibers are untwisted, and you get slivers, long, untwisted ropes of fibers, ready for the next step.

Combing for Yarn Quality

You might think you need to add in more softness and strength. If this applies then combing is your next step. It takes out short fibers as well as impurities, leaving you with longer and finer fibers. This leads to smoother and more uniform yarn.

Roving and Drawing

Then, using a roving frame, you twist these fine strands slightly to make a stronger roving yarn. The drawing process comes next. Before being spun, it stretches and aligns the fibers more uniformly. This process prepares your yarn for high speed spinning without breakage.

Spinning Process

Spinning is now the last step of yarn preparation. Yarn is twisted, drafted, and wound onto bobbins simultaneously with high speed spindles. You’ll watch your fiber become reformed into stable, stretchable yarns that can be fed into knitting machines.

Setting Up the Knitting Machine

Machine Selection

Depending on your budget and scale of production you can opt for manual, semi automatic or fully automatic machines. The structure of machines also differs: flatbed machines for panel fabrics or circular ones for tubular knits. The gauge size matters too. If you want chunky sweaters, use larger needles. Fine gauge machines are needed for finer fabrics, such as undergarments.

Parameters Considered

When choosing the correct setup for your knitting machine, take into account the type of yarn, the machine speed and the type of fabric design you are intending to knit. It also matters what knitting type you are doing, are you weft knitting or warp knitting? You must also think about how complicated the stitch is and how quickly the machine can do it.

Modern Machine Features

Electronic controls, real time monitoring, and even automatic fault detection are now offered by today’s machines. You could digitally program your design. You can use this to form complex patterns such as jacquards, lace, or textures without any manual intervention. It makes us more efficient and less wasteful.

Knitting Process Execution

Design Programming

You start by entering design specs such as stitch length and GSM (grams per square meter). These are settings that will affect how dense and what kind of fabric your fabric is. During runs, your production team will coordinate machine setup, make sure the right tension is being used, and monitor the output.

Weft Knitting in Action

In weft knitting you feed one continuous yarn, horizontally. The fabric has loops that interlock across their width. This method is perfect for sweaters, T shirts and socks. It’s fast and flexible, ideal for bulk production.

Warp Knitting in Action

Warp knitting provides more stable and less stretchy fabric if you require that. You use several yarns, each yarn goes into a separate needle vertically. It is often used in lingerie, sportswear, and automotive textiles. This results in a dense, stable, and durable fabric.

Post-Knitting Treatments and Finishing

The final touches on your fabric will be done after knitting, to make it look good, feel better and last longer.

• Heat Setting: On synthetic fabrics you heat to make the shape permanent and stop curling or distortion.
• Washing, Dyeing, Bleaching: These process will clean the clothes and give them the color tone and brightness you want.
• Calendaring, Brushing, Compacting: These mechanical treatments allow you to add texture, or reduce thickness.
• Shrinkage Control: The fabric is treated to control post wash shrinkage.
• Inspection and Packaging: Finally, examine each roll for flaws. When all is approved, you pack and label the fabric for shipping or storage.

Key Characteristics of Knit Fabrics

• Stretch and Recovery: Having this looped structure allows knit fabrics to stretch very easily. They will move with your body and return to shape, all while giving you both flexibility and resilience.
• Softness and Drape: They drape naturally and feel soft on your skin. Use them to make garments that drape beautifully without stiffness.
• Moisture Management and Breathability: Knit fabrics allow air to circulate in many. While cotton or rayon blends will keep you cool and dry, if you wear them in warm weather.
• Weight and texture variations: Knits come in a variety of weights, including lightweight jersey and thick sweater knits. They give you enough different textures and warmth to have lots of creative options.
• Durability and Maintenance: In general, knits are durable and easy to care for. Most of them can be machine washed and resist wrinkling better than woven fabrics.
• Fiber Content Impact: It makes a big difference what fibers are used. Polyester provides strength, cotton is soft and breathable, and rayon makes it smooth. You will want to match fiber content to garment purpose.

Main Categories of Knit Fabrics

Single Knit Fabrics

One set of needles are used to make single knits. They’re one sided with a smooth face and textured back. Common types include jersey knit and slub knit. These are soft feeling, have decent stretch, and are great for tees and dresses. However, they curl at the edges and can be unstable, so you have to be careful when sewing them.

Double Knit Fabrics

Fabric that looks the same on both sides is made with two needle beds and said to be double knits. This results in a thicker, more stable fabric that won’t curl – perfect if you want more structure. This includes Ponte and interlock knits. It also does well for jackets, skirts and office wear. It’s a go to for comfort with a polished look.

Warp Knit Fabrics

Machine made, warp knits differ in structure. It gives you more strength, but less stretch than weft knits. There are common types such as Tricot and Raschel. These are light and breathable fabrics. They are often found in lingerie, linings and activewear. For high volume production, clothing that needs to perform well, warp knits are very consistent.

Detailed Guide to Common Knit Fabric Types

A. Cotton Knit Fabric

Cotton knit fabric is 100% cotton or a cotton blend. It’s a soft, breathable fabric that’s easy to dye and meant for daily wear. It is usually found in T-shirts, baby clothes and undergarments. You’ll love its hypoallergenic quality if your skin is sensitive. However, it shrinks and does not offer the stretch that you get from the synthetic blends. Therefore, just make sure to prewash it before sewing.

B. Jersey Knit Fabric

One of the most common single knits is jersey knit. Flat surface with curled edge, it is lightweight. You may choose single jersey or double jersey. It is ideal if you want to print on T-shirts, dresses, bedsheets, activewear, etc. Cotton jersey is soft and breathable, while polyester jersey is better at wicking. If you’re looking for comfortable versatility, jersey knit is a great choice.

C. Rib Knit Fabric

The vertical ribs of the knit and purl stitches in this fabric alternate. You will see the extra stretch, especially across the width. The go-to fabric for cuffs, neckbands and waistbands. And you’ll find it in fitted tops. Select 1×1 or 2×2 rib style, and how much stretch you’d like to have. Rib knit has great elasticity and recovers well, making your garments keep shape.

D. Waffle Knit Fabric

Thermal knit or waffle knit, so called because of the honeycomb texture, is unique. While it can be breathable, it traps warmth. Primarily made from cotton or blends, it is perfect for layers such as thermal tops and casual clothing. This is your fabric if you’re looking for comfort in cool weather.

E. Double Knit Fabric

Double knit fabric is made up of two layers knit together. It holds its shape well and doesn’t curl at the edges. This is heavy fabric that is best used for structured garments like dresses, jackets, and pants. Common types are Ponte de Roma and Interlock knits. Double knit is if you want durability with a polished look.

F. Sweater Knit Fabric

Sweater knits are like hand knitted sweaters and can be fine or chunky. They frequently consist of wool, acrylic, or blends. Their cozy feel and excellent drape will be enjoyed. These knits are the perfect choice for cardigans, pullovers, scarves, and outerwear. When choosing your style you will notice differences in gauge and patterns such as cables or ribs.

Specialty Knit Fabrics

If you’re scouring the mall for summer tops, relaxed tees, or weekend outfits that aren’t too busy and feel cool, reach for slub knit.

C. Hacci Knit

Hacci knit has a soft sweater feel but drapes beautifully. It’s loosely knit and often blended with rayon or polyester for added softness. If you’re looking for flowy cardigans, cozy pullovers, or lightweight fall tops, you’ll want to go with hacci. It’s a go to if you want warmth without bulk.

D. French Terry Knit

On one side French terry has a smooth face and on the other it has small loops. It’s breathable, absorbent, and lightweight enough. It’s great for hoodies, joggers and loungewear. No matter if you’re relaxing or running errands, you stay comfortable.

E. Interlock Knit

You get smooth surfaces on both sides of the fabric due to interlock knit. Standard jersey is thinner and not nearly as stable. This is a good one when you’re shopping for baby clothes or premium T-shirts. The fabric holds up well, does not curl and is soft against the skin.

Choosing the Right Knit Fabric for Your Project

Evaluate Key Fabric Qualities

The stretch, drape, weight, and durability of the fabric is always something to check. Choose a four way stretch knit if you need flexibility. Go for heavier fabrics with less drape when you want structured looks. For best results, match the fabric’s weight and stretch to your sewing pattern.

Think About Season and Comfort

Think about when and where you are going to use the item. Fleece is also a great choice for winter, it’s warm, thick knits. For summer, light cotton jerseys are nice. Season appropriate fabric ensures comfort and practicality.

Check Care Needs and Longevity

You want your end product to last. Seek out knits that will lend themselves to washing easily, and that won’t pill. Before buying, check the care label.

Factor in Cost and Availability

Keep your budget in mind, but don’t skimp on quality. Online or in your local textile markets, you can source great fabrics. Always request swatches if possible.

Knit Fabric Maintenance Tips

Different fabrics can be washed and dried differently

Always check the label first. Cold water and a gentle cycle are best for cotton knits. Cool water and low spin settings are best for synthetic knits, such as polyester or spandex. Most knits should be air dried so as not to shrink or distort the shape.

Preventing Shrinkage and Pilling

Keep it away from hot water and high heat. Wash garments inside out to reduce friction. Also, to avoid pilling from rough contact, you can use a mesh laundry bag.

Storage and Ironing Tips

Hang your knits, as hanging forces them to stretch. If you must do ironing, do it on a low temperature. To protect the fibers, place a cotton cloth between the iron and your fabric.

Fabric Softeners and Detergents

Do not use fabric softeners on stretchy knits; they can break down elastane. Use mild, fragrance free detergents to retain the durability of fibers and color.

Applications of Different Knit Fabric Types
