The Interlock Fabric emerges as a superior choice, distinguishing itself as a robust, double-sided, woven patterned fabric highly favored in the apparel and sportswear industries.
So, what exactly defines Interlock Fabric? It is a knitted reversible fabric, notable for its exceptionally smooth appearance on both sides.
This fabric is characterized by its significant thickness, strength, and a moderate level of elasticity. A key advantage for designers and manufacturers is that Interlock fabric hardly curls at the edges, simplifying cutting and sewing operations.
Often described as a micro fabric due to its smooth texture and breathable properties, it is typically treated to resist pilling, ensuring longevity and maintaining its aesthetic appeal.
Known also as Double Knit Fabric or Interlock Jersey Fabric, its unique construction contributes significantly to its growing popularity.
Manufacturing Process of Interlock Knit
Understanding the sophisticated manufacturing process behind Interlock knit fabric illuminates its superior qualities.
How Interlock Fabric is Knitted
Unlike traditional woven fabrics, which are formed by the perpendicular intertwining of warp and weft threads, interlock knit fabric is created through the interlocking loops of a single, continuous thread.
This unique looping process results in a balanced stretch fabric that boasts excellent recovery, allowing it to move with the wearer and retain its shape.
Circular knitting machines are instrumental in this formation, contributing to the fabric’s inherent comfort, durability, and distinctive structure that sets it apart from other garments.
Double Knit Structure
Interlock is inherently a double-knitted fabric, presenting an identical appearance on both its upper and lower surfaces, giving it a perceptibly layered feel.
This double jersey structure is achieved using a combination of cylinder and dial-shaped circular weft knitting machines. Stainless steel needles cross and work alternatively to produce this double knit, imparting a characteristic softness to the fabric.
This intricate process results in a fabric with a face wale directly opposite a reverse wale, creating a structure that is remarkably similar to woven textiles, making cutting and sewing operations considerably easier.
Essential Finishing Processes
Beyond the knitting, specific finishing processes further enhance Interlock fabric’s properties:
- Brushing: Cotton-made interlock fabric is often brushed on its inner surface by manufacturers to enhance its warmth and overall comfort, a technique crucial for creating warm cotton items. This technique is not typically applied to woolen fibers due to their intrinsic thermal characteristics.
- Ironing: To achieve optimal stability and manage knitting tensions, Interlock fabric undergoes ironing. This can be performed with steam or by passing the fabric through two hot metal cylinders.
Versatility of Interlock Fabric Yarns
The versatility of Interlock fabric is largely attributed to its adaptable composition, utilizing a range of fiber types to achieve diverse properties.
Diverse Fiber Types Used
Interlock fabric can be composed of a variety of materials, including polyester, wool, bamboo, rayon, silk, and cotton. It can be made entirely from a single fiber, such as 100% cotton or 100% polyester.
Furthermore, blends are common, incorporating materials like cotton wool, and chemical fibers such as acrylic, polyester, and spandex, to achieve specific performance characteristics.
Benefits of 100% Cotton Interlock
100% cotton-made interlock fabric is particularly esteemed for being eco-friendly, exceptionally soft, breathable, and stretchy.
It is well-suited for both warm and cold weather clothing due to its excellent moisture absorption and efficient air circulation, ensuring wearer comfort. This makes it a highly desirable choice for everyday wear and a wide array of casual items.
Exploring the Types of Interlock Fabric and Their Specific Uses
Interlock fabric encompasses several distinct types, each offering unique attributes tailored for particular applications.
Cotton Interlock
As a common type, Cotton Interlock is celebrated for its 100% soft and breathable characteristics. It provides excellent moisture absorption and proper air circulation, enhancing wearer comfort. This strong, washable fabric is ideal for everyday wear, baby clothes, undergarments, and t-shirts.
Polyester Interlock
Polyester Interlock is a synthetic fiber derived from petroleum. Its synthetic nature endows it with desirable attributes such as high resilience and resistance to stretching, meaning it will not shrink after washing.
This fabric dries quickly, and its low water absorbency, coupled with crucial moisture-wicking properties, makes it an ideal choice for sportswear like athletic tops and leggings.
Nylon Interlock (Often Blended with Spandex)
While it can feature nylon as a primary material, Nylon Interlock is frequently offered in a blended version with spandex.
This combination leverages nylon’s inherent strength with spandex’s elasticity, creating a highly durable and flexible fabric. It is extensively used in activewear garments, providing essential support and stretchability.
This blended interlock offers exceptional shape retention and adequate compression without compromising comfort, even after repeated uses.
Bamboo-Rayon Interlock
Gaining substantial popularity in recent years, Bamboo-Rayon Interlock is prized for its eco-friendly nature, as bamboo plants require minimal water and resources for textile production.
This fabric type features excellent breathability and natural anti-bacterial properties that effectively inhibit the growth of odor-causing bacteria. Its applications include intimate apparel, such as underwear and sleepwear.
Modal Interlock
Considered a luxurious variant, Modal Interlock fabric is derived from beech tree cellulose. These fibers are renowned for their exceptional softness and a texture akin to silk.
Favored in the high-end fashion industry, Modal Interlock is used for elegant dresses and tops due to its superb drapeability, excellent color retention, and moisture absorption abilities, contributing to a comfortable and sophisticated appearance.
Key Properties and Characteristics: What Makes Interlock Superior
The distinctive properties of Interlock fabric underscore its widespread appeal and performance capabilities.
Physical Attributes and Durability
Interlock fabric is notably thick, typically ranging between 150 to 450 GSM, distinguishing it as heavier than similar fabrics. It boasts a smooth, polished finish on both sides, which often eliminates the need for an additional lining.
This fabric exhibits high durability, strong resistance to wear and tear, and a commendable pilling resistance rating of 3 to 4 grades.
Its structure ensures good stability, clear lines, and a clean textile surface. Furthermore, Interlock is known for its high color fastness, resulting in bright and vivid hues.
Comfort and Performance Features
Interlock fabric is widely appreciated for its soft hand touch and airy texture, making it exceptionally pleasant to wear. Its unique construction traps air fibers, making it both insulant and highly breathable, an ideal combination for sporting activities.
It demonstrates good moisture absorption ability, effective sweat volatility, and superior moisture-wicking and quick-drying mechanisms, often coupled with anti-bacterial properties.
The fabric also possesses good elasticity and excellent recovery, allowing for flexible movement and retaining its shape even after repeated washing and wearing.
The air layer between its front and rear surfaces provides better heat insulation compared to single-yarn knitted fabrics, contributing to warmth.
Ease of Handling and Maintenance
A significant advantage for manufacturing and home sewing is that Interlock fabric hardly curls at the edges, making it considerably easier to work with and sew.
Diverse Applications: Where Interlock Fabric Shines
The versatility of Interlock fabric allows it to shine across a multitude of applications in the textile industry.
