Knit fabric

Definition & Production

Knit fabric is created by interlocking yarns in a series of loops, using knitting machines with needles. Unlike woven fabrics (made by weaving threads over/under each other), knits are flexible and stretchy due to their looped structure. Production methods include:

• Weft Knitting: A single yarn loops horizontally (e.g., t-shirts, sweaters).

• Warp Knitting: Multiple yarns loop vertically, offering more stability (e.g., athletic wear, lingerie).

Common Types

• Jersey: Soft, smooth face with slight ribs on the back (used in t-shirts, dresses).

• Rib Knit: Vertical ridges, highly elastic (ideal for cuffs, collars).

• Interlock: Thicker, reversible, and less stretchy (common in baby clothes, dresses).

• Ponte: Dense, stable, and structured (used in pants, blazers).

Key Properties

• Stretch & Elasticity: Naturally stretchy, with options for 2-way (horizontal) or 4-way (multi-directional) stretch.

• Comfort: Breathable, drapes well, and conforms to the body.

• Durability: Resists fraying but may curl at edges. Prone to pilling over time.

Applications

• Apparel: T-shirts, leggings, sweaters, socks, activewear, underwear.

• Home Textiles: Stretchy blankets, upholstery.

• Materials: Cotton (softness), wool (warmth), polyester (durability), or blends with spandex (added stretch).

Care Tips

• Machine wash cold to prevent shrinking.

• Lay flat to dry to avoid stretching.

• Use a fabric shaver to remove pills.

Knit vs. Woven Fabrics

• Knit: Stretchy, flexible, and less prone to wrinkles.

• Woven: Structured, non-stretchy (unless elastane is added), and more formal.

Knit fabrics are versatile, prioritizing comfort and movement, making them a staple in everyday and performance wear.
