  • Accessories
  • Activewear
  • Swimwear
  • Intimate Apparel
  • Outerwear
  • Sleepwear
  • Costumes
  • Fashion Accessories

Weft knitted fabrics typically stretch more in the width direction. This characteristic allows for ease of movement, making them suitable for active lifestyles. The tension of each loop can be adjusted, which affects the stretchability of the fabric. Thicker yarns create bulkier fabrics that can stretch but may have less recovery than thinner yarns.

Tip: Design techniques like ribbing can enhance stretchability in multiple directions, making weft knitting a versatile choice for many garments.

Warp Knitting

Warp knitting, on the other hand, uses vertical yarns to create fabric. This method produces a different type of knitted fabric with distinct properties. Here are some important aspects of warp knitting:

• Production Speed: Warp knitting machines can produce large pieces of fabric much faster than traditional methods. This efficiency is a key reason for their widespread use in factories.
• Elasticity: Warp knitted fabrics tend to be elastic in length, making them suitable for applications that require stretch without losing shape.
• Applications: Common products made using warp knitting include:

The elasticity of warp knitted fabric is less than that of weft knitted fabric. However, it offers excellent shape retention, making it ideal for structured garments. The loops produced in warp knitting are created to length, which contributes to the fabric’s durability.

Inspection and Quality Control of Knitted Fabric

Quality control is essential in the production of knitted fabric. You want to ensure that the final product meets high standards. This process involves thorough inspection and checking for defects.

Checking for Defects

When inspecting knitted fabric, you should follow standard procedures to identify any issues. Here’s a checklist to guide you:
