Tirupur, often referred to as the “Knitting Capital of India” is renowned for its large-scale knit t-shirt manufacturers, particularly for t-shirts. The manufacturers in Tirupur employ a variety of knitting techniques, which can be broadly categorized into two main types: weft knitting and warp knitting. Here’s an overview of the key knitting techniques used by t-shirt manufacturers in Tirupur:

- Use: Commonly used for basic t-shirts.
- Double Jersey Knit (Interlock):
- Characteristics: Heavier and thicker than single jersey, with the same appearance on both sides.
- Use: Used for higher-quality t-shirts that require more structure.
- Rib Knit:
- Characteristics: Stretchy with a distinct vertical rib pattern, good elasticity.
- Use: Often used for collars, cuffs, and trims on t-shirts.
- Pique Knit:
- Characteristics: Textured, with a waffle-like pattern, allowing for good breathability.

2. Warp Knitting
This technique involves interlocking yarn loops in a vertical sequence. It is less common for t-shirts but is used for specific fabric properties:
