Overview of Fabrics Produced by Weft Knitted Technology
Weft knitting is a versatile and widely used textile manufacturing technique where loops of yarn are formed in a horizontal (weft) direction to create fabrics with unique properties such as stretch, flexibility, and comfort. This method is employed to produce a diverse range of fabrics suitable for apparel, sportswear, and technical textiles. The following sections provide a comprehensive overview of key fabric types produced through weft knitting, categorized into single jersey, double jersey, interlock, and collar and cuff fabrics, highlighting their characteristics, applications, and variations.
Single Jersey Fabrics
Single jersey fabrics are knitted using a single set of needles, resulting in a lightweight, flexible material with distinct front and back sides. The front displays a smooth, flat surface with visible vertical loops, while the back shows a more textured, looped appearance. These fabrics are popular for their breathability, softness, and elasticity, making them ideal for casual wear, t-shirts, and activewear. Below are the primary types of single jersey fabrics:
Plain Single Jersey
Plain single jersey is the most basic and widely used weft-knitted fabric, characterized by its simple loop structure. It is lightweight, soft, and drapes well, offering excellent comfort for everyday garments like t-shirts, dresses, and undergarments. Its elasticity allows for ease of movement, but it may curl at the edges due to its single-knit construction.
Spandex Single Jersey
Incorporating spandex (elastane) into plain single jersey enhances its stretch and recovery properties. This fabric provides superior elasticity, making it ideal for form-fitting garments such as leggings, sportswear, and swimwear. The addition of spandex ensures the fabric retains its shape after repeated stretching, offering both comfort and durability.
Single Lacoste
Single Lacoste, also known as single pique, features a textured, waffle-like surface created by a combination of knit and tuck stitches. This fabric is breathable and slightly thicker than plain single jersey, making it suitable for polo shirts and casual tops. Its distinctive pattern adds aesthetic appeal while maintaining comfort.
Double Lacoste
Double Lacoste is a variation of single Lacoste with a more pronounced textured pattern, achieved through a different arrangement of knit and tuck stitches. It offers a bolder appearance and slightly greater thickness, making it a popular choice for premium polo shirts and sportswear that require both style and breathability.
Single Pique
Single pique is similar to single Lacoste but features a finer, more subtle textured pattern. It is lightweight and breathable, commonly used in polo shirts and casual apparel. Its delicate surface adds a refined look while maintaining the comfort associated with single jersey fabrics.
Double Pique
Double pique has a more intricate and pronounced texture than single pique, offering a thicker and more structured fabric. It is often used in high-quality polo shirts and sportswear, providing a balance of durability, breathability, and aesthetic appeal.
Polo Pique
Polo pique is specifically designed for polo shirts, combining the textured appearance of pique with the softness and elasticity of single jersey. It is durable, breathable, and maintains its shape well, making it a staple in sportswear and casual fashion.
French Terry
French terry is a single jersey fabric with a smooth front and a looped, towel-like back. The looped structure provides excellent absorbency and a soft, cozy feel, making it ideal for sweatshirts, hoodies, and loungewear. Its thickness offers warmth without sacrificing breathability.
Spandex Terry
Spandex terry incorporates elastane into French terry, enhancing its stretch and recovery properties. This fabric is perfect for fitted activewear and loungewear, offering a snug yet comfortable fit that accommodates movement while maintaining its shape.
Fleece
Fleece is a single jersey fabric with a brushed or napped back, creating a soft, fuzzy surface that provides exceptional warmth and insulation. It is commonly used in outerwear, jackets, and blankets, offering a lightweight yet cozy option for cold-weather garments.
Spandex Fleece
Spandex fleece combines the warmth and softness of fleece with the elasticity of spandex. This fabric is ideal for fitted outerwear and activewear, providing flexibility and comfort while retaining the insulating properties of traditional fleece.
Double Jersey Fabrics
Double jersey fabrics are knitted using two sets of needles, resulting in a thicker, more stable fabric with similar appearances on both sides. These fabrics are less prone to curling and offer greater durability and structure compared to single jersey. They are commonly used in garments requiring stretch and shape retention, such as ribbed cuffs, collars, and fitted apparel.
1x1 Rib/Spandex
1x1 rib fabric alternates one knit stitch with one purl stitch, creating a highly elastic, vertically ribbed texture. When blended with spandex, it offers enhanced stretch and recovery, making it ideal for cuffs, collars, waistbands, and form-fitting garments like t-shirts and activewear.
2x1 Rib/Spandex
2x1 rib features two knit stitches followed by one purl stitch, resulting in a wider ribbed pattern than 1x1 rib. With spandex, it provides excellent elasticity and is used in similar applications, offering a slightly bolder texture for added visual interest.
2x2 Rib/Spandex
2x2 rib alternates two knit stitches with two purl stitches, creating a more pronounced ribbed effect. When combined with spandex, it offers superior stretch and recovery, making it suitable for heavy-duty cuffs, collars, and performance wear that requires both structure and flexibility.
Interlock Fabrics
Interlock fabrics are a subset of double jersey knitting, created by interlocking two layers of single jersey fabric. This results in a smooth, stable, and reversible fabric with identical appearances on both sides. Interlock fabrics are thicker, denser, and less stretchy than single jersey, making them ideal for structured garments.
Plain Interlock
Plain interlock is a smooth, dense fabric with a soft hand feel and moderate stretch. It is commonly used in t-shirts, dresses, and baby clothing due to its durability, comfort, and resistance to pilling. Its balanced structure makes it versatile for various apparel applications.
Drop Needle Interlock
Drop needle interlock features a textured pattern created by selectively dropping stitches, resulting in a ribbed or striped effect. This fabric is used in casual and athletic wear, offering a unique aesthetic while maintaining the stability and softness of interlock.
Spandex Interlock
Spandex interlock incorporates elastane for enhanced stretch and recovery. This fabric is ideal for fitted garments such as sportswear, leggings, and dresses, providing a smooth, structured appearance with added flexibility.
Collar and Cuff Fabrics
Collar and cuff fabrics are specialized weft-knitted structures designed for the necklines and cuffs of garments, particularly polo shirts and formal wear. These fabrics are typically ribbed or interlock-based, offering elasticity, shape retention, and aesthetic appeal.
Plain/Solid Collar
Plain or solid collars are made from rib or interlock fabrics, providing a smooth, structured appearance. They are commonly used in polo shirts and formal shirts, offering durability and a clean, professional look.
Jashaving Collar
Jashaving collars feature a textured or patterned surface, often created through specialized knitting techniques. These collars add a decorative element to garments, making them suitable for premium polo shirts and designer apparel.
Jacquard Collar
Jacquard collars incorporate intricate patterns or designs woven directly into the fabric through advanced knitting techniques. They are used in high-end garments, offering a sophisticated and customized appearance.
Tipping Collar
Tipping collars feature contrasting colors or patterns along the edges, adding a stylish accent to polo shirts and sportswear. The tipping effect enhances visual appeal while maintaining the functionality of ribbed or interlock fabrics.
Race Collar
Race collars are designed with a sleek, streamlined appearance, often used in performance wear. They provide a snug fit and enhanced durability, making them ideal for athletic and casual garments.
Stripe Collar
Stripe collars feature horizontal or vertical stripes knitted into the fabric, offering a bold and sporty aesthetic. They are popular in team uniforms and casual polo shirts, combining style with functionality.
