How Knit Fabric Is Made

The Knitting Process

Knit fabric is made by looping yarn in a series of connected stitches. There are two main types of knitting techniques used to create knit fabrics:

• Weft Knitting: The yarn runs across the width of the fabric, which creates the classic stretchy and flexible material often used in T-shirts, hoodies, and casual wear.
• Warp Knitting: The yarn runs vertically, creating a more stable fabric that can be used for garments like sportswear, tights, and socks.

The loops in knit fabric allow it to stretch naturally, offering flexibility and comfort.

Types of Knit Fabric

• Jersey Knit: A smooth, lightweight knit commonly used for T-shirts and basic garments.
• Rib Knit: A type of knit that features raised lines, often used in cuffs, collars, and waistbands for added elasticity.
• Interlock Knit: A variation of jersey knit that is denser and thicker, providing a more substantial feel.
• French Terry: A type of knit fabric that has loops on one side and a smooth surface on the other, commonly used in sweatshirts and activewear.
• Fleece: A warm, brushed version of knit fabric often used for jackets and winter wear.

Key Features of Knit Fabric

Stretch and Flexibility

Knit fabrics offer natural stretch, making them comfortable and suitable for activewear, form-fitting designs, and everyday garments. This is one of the key reasons why knit fabrics are used in clothing that requires ease of movement, such as leggings, T-shirts, and sports jerseys.

Softness and Comfort

Knit fabrics, especially those made from cotton or cotton-blend fibres, are soft against the skin, making them ideal for casual wear and uniforms.

Breathability

Because knit fabrics have open loops, they allow air to pass through easily, which enhances breathability and moisture wicking. This feature makes knit fabrics especially popular for sports and activewear.

Durability

Knit fabrics are highly durable, particularly when made from polyester or blended fibres. The fabric's stretchability prevents it from easily tearing or losing shape, which is ideal for clothing that experiences regular movement or wear.

Why Knit Fabric Is Ideal for Custom Printing

Knit fabrics are compatible with a variety of printing techniques used in custom garment production. These fabrics provide a smooth surface for clear, vibrant designs, and their flexibility accommodates a wide range of artwork styles.

Screen Printing

Screen printing works well on knit fabrics, particularly cotton and cotton-blend jerseys. The ink sits well on the fabric, providing strong opacity and vibrant colours.

Direct-to-Garment (DTG)

DTG printing is highly effective on cotton-based knit fabrics, as the ink bonds directly to the fibres. This method is ideal for full-colour, detailed designs, making it a popular choice for custom T-shirts and other knit-based garments.

Heat Transfers

Heat transfer printing can be used on knit fabrics, particularly for smaller designs or custom names. Vinyl heat transfers work particularly well on cotton and polyester knit fabrics.

Embroidery

Embroidery on knit fabric, especially heavier versions like interlock or fleece, works well for logos, monograms, and smaller design elements. The stretch of knit fabric should be considered to avoid puckering around the stitching.

Common Applications in Australia

Knit fabric is commonly used in a wide variety of garments, including:

• T-Shirts: One of the most popular applications of knit fabric, particularly for promotional events, retail merchandise, and casual wear.
• Activewear: Knit fabrics, especially jersey and fleece, are ideal for sportswear, fitness apparel, and athleisure.
• Polos: Cotton or polyester knit fabrics are commonly used for polos in corporate uniforms and schoolwear.
• Hoodies and Sweatshirts: Fleece and French terry knits are used for comfortable, warm outerwear.
• Leggings and Sportswear: Stretchable knit fabrics are essential for garments designed for movement.

Benefits for Australian Businesses

Knit fabric is highly versatile, comfortable, and durable, making it a preferred choice for a wide range of industries:

• Retail: Knit fabrics are ideal for casual, stylish retail collections and event merchandise.
• Corporate Uniforms: Knits, such as cotton-blend polos, provide both comfort and a professional appearance for corporate staff.
• Sports and Fitness: Activewear made from knit fabric ensures freedom of movement while maintaining a sleek, modern look.
• Promotional Apparel: Custom-printed T-shirts, hoodies, and tank tops made from knit fabric offer long-lasting branding opportunities at events, festivals, and community gatherings.

Practical Considerations

Fabric Weight

The weight of the knit fabric should be selected based on the intended use. Lighter fabrics (e.g., jersey) are suitable for warmer weather or casual wear, while heavier fabrics (e.g., fleece) are more suitable for outerwear and winter uniforms.

Fabric Care

Some knit fabrics, particularly those made from cotton, may shrink slightly after washing. Pre-washing and offering care instructions (e.g., washing in cold water, air drying) can help maintain garment size and shape.

Print Durability

Knit fabrics are generally print-friendly, but care must be taken to select the right ink type and ensure proper curing for long-lasting results, especially for garments that will be washed frequently.

Knit Fabric in Professional Garment Printing

Knit fabrics provide an ideal combination of comfort, flexibility, and printability, making them a staple in custom garment production. Whether for casual T-shirts, activewear, or retail-ready garments, knit fabrics offer versatility and quality that Australian businesses rely on.

For companies seeking affordable yet high-quality promotional products or custom uniforms, knit fabric offers a reliable base for vibrant, long-lasting prints.
