Question

In comparison with woven fabric, the knitted fabric with same GSM is:
A. stiffer and has harsh feel
B. more stretchable
C. more thicker
D. more porous Choose the correct answer from the options given below:

• A. B, C, D only
• B. A, B, C only
• C. A, B, D only
• D. A, C, D only

Hint:

Think of a T-shirt (knit) vs. a formal shirt (woven). Even if they weigh the same, the T-shirt is thicker, more porous, and far more stretchable.

Answer 1

The Correct Option is A

Concept: GSM (Grams per Square Metre) measures the weight of a fabric. Even if a woven and knitted fabric weigh the same, their structural geometry (interlacing vs. interlooping) creates vastly different physical properties.

Step 1: Analyzing Knitted Structure Advantages.

• B (More stretchable): Because knitted fabrics are made of intermeshing loops, the loops can easily deform and extend when pulled, making knits inherently more elastic than wovens.
• C (More thicker): The three-dimensional nature of a loop requires more space in the Z-direction (thickness) compared to the flat interlacing of warp and weft yarns.
• D (More porous): The loop structure contains significantly more "dead space" or air gaps between the yarns, leading to higher porosity and air permeability.

Step 2: Exclusion.
A (Stiffer and has harsh feel) is incorrect. Knitted fabrics are actually known for being much softer and more flexible (drapable) than woven fabrics of equivalent weight.
