Depending on the thickness of the warp and weft yarns used, plain weave fabrics can be categorized into coarse plain cloth, medium plain cloth, and fine plain cloth.

1. Coarse Plain Cloth
   Also known as coarse cloth, it is mostly woven from pure cotton thick yarn. Its characteristics include a rough, thick texture, with more cotton knots and impurities on the surface, making it sturdy and durable. Coarse cloth sold in the market is mainly used for garment interlining. In mountainous rural areas and coastal fishing villages, this type of cloth is sometimes used to make shirts and bed linens. After dyeing, it can also be used as material for shirts and pants.

3. Medium Plain Cloth
   Also referred to as market cloth or white market cloth when sold in the market, it is made from medium-count cotton yarn or viscose rayon yarn, cotton-viscose blended yarn, polyester-cotton blended yarn, etc. Its features include a tighter structure, a smooth and full-bodied surface, firm texture, and a relatively stiff hand feel. Market plain cloth is primarily used for bed linens and lining materials, but can also be used for shirts and pants. Medium plain cloth is often used as raw fabric for bleached cloth, colored cloth, and printed cloth, which are then processed for use in garments.

Fine cloth sold in the market is mainly used similarly to medium plain cloth. It is often used as raw fabric for bleached cloth, colored cloth, and printed cloth. After processing, it is suitable for use in undergarments, pants, summer outerwear, blouses, and other types of clothing.
