Based on the weaving method, there are two main types of knitted fabric: weft knitted fabric and warp knitted fabric. These two versions differ significantly in their structural characteristics, properties, and applications. This article will focus on comparing the two methods, helping you make an informed decision when shopping or choosing materials for production and business.
1. What are Weft Knitted Fabric and Warp Knitted Fabric?
Weft knitted fabric is a type of textile produced by interlacing yarns horizontally from left to right. This process creates parallel rows (or loops) of stitches. Weft knitted fabric is typically very stretchy and soft, so it is often used for items like T-shirts and underwear.
Warp knitted fabric is a type of textile produced by interlacing yarns vertically from top to bottom. This process creates parallel columns (or loops) of stitches that are perpendicular to the rows of weft knitted fabric. Warp knitted fabric is typically highly durable and less stretchy compared to weft knitted fabric. It is often used for sweaters and jackets.
2. Comparing Weft Knitted Fabric and Warp Knitted Fabric
Below is a detailed comparison of the production methods, characteristics, and applications of the two types of knitted fabric.
2.1. Production Method
With weft knitted fabric, the loops are formed horizontally. The knitting process repeats continuously, creating overlapping rows of loops. The production process for weft knitted fabric is simpler because it only uses one yarn at a time. The fabric can be made from both staple fibers and filament yarns, providing many options for material and fabric softness. The knitting process only uses latch needles, which helps create even, soft loops.
With warp knitted fabric, the loops are formed vertically. The needles move up and down to create columns of loops. You need to use a warp beam and multiple yarns simultaneously to create a strong, stable structure for this type of fabric. Typically, only filament yarns are used to knit warp knitted fabric. The knitting process can use various types of needles, such as latch needles, bearded needles, and compound needles, offering diverse and flexible knitting techniques.
2.2. Characteristics
Here is a comparison of the characteristics of weft knitted fabric and warp knitted fabric:
- Elasticity: Weft knitted fabric has high elasticity because the horizontal loops can stretch well. This makes the fabric soft and comfortable to wear, suitable for products requiring stretch such as T-shirts and sweaters. In contrast, warp knitted fabric has lower elasticity due to its sturdy vertical structure. Therefore, it is less stretchy and not as comfortable as weft knitted fabric.
- Durability: Warp knitted fabric is generally more durable. Its vertical knitting structure makes the fabric less prone to deformation after multiple uses and washes. Meanwhile, weft knitted fabric, although it has good stretch, is more likely to pill and deform after a period of use.
- Surface: Weft knitted fabric is generally softer and smoother due to the horizontal knitting method, which provides a comfortable feel against the skin. Conversely, warp knitted fabric has a firm surface and is less likely to pill, giving it a stiffer feel.
- Shape Retention: Warp knitted fabric is notable for its good shape retention due to its strong vertical knitting structure. This helps the fabric maintain its shape and not wrinkle after many washes. In contrast, weft knitted fabric can easily deform and lose its shape after being used for a long time.
2.3. Applications
The different structures of the two fabrics lead to separate applications for each type, providing consumers with a wide range of shopping choices.
Specifically, the elasticity of weft knitted fabric is often applied to products that need good stretch, such as T-shirts, leggings, dresses, and underwear. Its smooth surface and good moisture-wicking ability are also advantages that make weft knit a top choice for comfortable and active wear.
Meanwhile, warp knitted fabric is often used to produce products that need a sturdy shape, such as trousers, jackets, and woolen items. In addition, warp knitted fabric is also a suitable material for producing high-end products that require aesthetics and high durability, such as woolen coats and cashmere sweaters.
3. Should You Choose Weft Knitted Fabric or Warp Knitted Fabric?
The choice between weft knitted fabric and warp knitted fabric should be based on the desired characteristics and features of the product. Weft knitted fabric is soft and flexible, while warp knitted fabric is noted for its durability and good shape retention.
Weft knitted fabric is ideal if you are looking for fabric for soft and stretchy apparel products such as T-shirts, leggings, dresses, and underwear. This type of fabric is also suitable for sportswear because its elasticity allows the wearer to move and exercise easily.
Warp knitted fabric is a good choice if you need a durable fabric that holds its shape well and is less prone to deformation after long-term use. Because of its high production cost, this type of fabric is often found in swimwear, jackets, high-end underwear, and products that require sturdiness and durability.
