When it comes to creating comfortable, versatile, and stylish clothing, knit fabrics play a pivotal role. Knit fabrics are the foundation for many of our favorite garments, from cozy sweaters to stretchy leggings. However, before these fabrics make their way into our closets, they undergo a complex finishing process that turns raw material into luxurious textiles. In this blog post, we’ll explore the knit fabric finishing process and the various steps involved.
What Do You Mean By Knit Fabric?
Knit fabric is a type of textile material that is created by interlocking a series of yarn loops in a specific pattern. This interlocking structure is different from woven fabrics, where yarns are typically woven over and under each other at right angles. Knit fabrics are characterized by their stretchiness and flexibility, making them suitable for a wide range of clothing and textile products.
Key Characteristics Of Knit Fabrics Include:
Stretchability: Knit fabrics are known for their natural elasticity, which allows them to stretch and recover without losing their shape. This property makes knit fabrics comfortable to wear and well-suited for garments that need to accommodate body movements.
Breathability: Knit fabrics often have a more open and breathable structure compared to tightly woven fabrics. This breathability can make them suitable for warm-weather clothing.
Comfort: Knit fabrics are soft and comfortable against the skin due to their stretchiness and flexibility.
Versatility: Knit fabrics come in various weights and textures, making them suitable for a wide range of clothing items, from T-shirts and sweaters to activewear and undergarments.
Wrinkle resistance: Knit fabrics are less prone to wrinkling compared to some woven fabrics, which can make them easier to care for.
Common examples of knit fabrics include jersey, interlock, rib knit, and piqué. These fabrics are often used in the fashion industry to create garments like T-shirts, sweaters, dresses, leggings, and more. The type of knit, fiber content, and finishing processes can all influence the characteristics and performance of the final fabric. Knit fabrics are a staple in the textile industry and are appreciated for their comfort and versatility.
The Knit Fabric Finishing Process:
Knitting:
The process begins with knitting machines that transform yarn into fabric. These machines use a series of needles to create interlocking loops, resulting in a fabric that can stretch and recover, making it ideal for comfortable clothing.
Scouring:
 After knitting, the fabric may contain impurities and oils. Scouring involves washing the fabric to remove these impurities, leaving behind a clean surface for further treatment.
Dyeing and Printing:
This step involves adding color and patterns to the fabric. Dyeing uses various techniques to impart a specific color to the fabric, while printing adds intricate designs. Both processes enhance the aesthetic appeal of the fabric.
Stentering:
Stentering is a critical process that involves stretching the fabric widthwise to ensure it is uniform and dimensionally stable. This also helps in setting the fabric’s width, reducing the risk of distortion.
Heat Setting:
In this step, the fabric is exposed to high temperatures to set its shape and size. This ensures that the fabric will maintain its intended dimensions during use and subsequent washes.
Finishing:
Finishing treatments are applied to improve the fabric’s hand feel, appearance, and performance. Various finishing techniques can be used, such as calendering, brushing, or raising the fabric’s surface for a softer texture.
Inspection And Quality Control:
At this stage, the fabric undergoes a thorough quality control check. Any defects or irregularities are identified and addressed to ensure the final product meets the required standards.
Cutting And Sewing:
After passing all quality checks, the fabric is cut and sewn into the desired garments or textile products. The finishing process ensures that the fabric is ready to be transformed into comfortable and stylish clothing.
Types Of Knit Fabric Finishes:
Knit fabric finishing can result in a wide range of textures, appearances, and performance characteristics. Here are some common types of knit fabric finishes:
Mercerization:
This finish enhances the fabric’s luster, strength, and dye absorption by treating it with a caustic solution.
Bio-polishing:
This process softens the fabric and reduces pilling, making it ideal for T-shirts and other apparel.
Enzyme wash:
Enzymes are used to create a worn-in or vintage look, giving the fabric a softer hand feel.
Anti-pilling finish:
A finish that reduces the formation of pills on the fabric surface, ensuring a smoother appearance and longer garment life.
