Generally speaking, fabrics fall into two main categories: woven fabrics and knitted fabrics.
Knitted fabrics are made by using needles to form loops from yarn or filament, which are then interlooped with one another.They have large gaps between the loops, giving them excellent air permeability and a soft hand feel.Under external tension, the loop structure easily deforms, resulting in high extensibility. This is why knitted garments stretch and have elasticity.
Woven fabrics are formed by interlacing warp and weft yarns perpendicularly to each other.They feature a tight, cross-like structure where yarns are fully straightened.Compared with knitted fabrics, they have lower extensibility, are firm, sturdy, and less prone to deformation, but their air permeability is lower due to the compact structure.
Quick Way to Distinguish Regular Knitted & Woven Fabrics - By Stretching
Knitted fabric is generally softer. When stretched, it expands sideways; the texture thickens, gaps widen, and it deforms. It returns to its original shape when released.
Woven fabric has a crisp, structured hand feel. Its shape and structure do not change significantly when stretched.
