Fabric knowledge: The shape and regularity of the warp and weft threads that intersect each other in the fabric is called fabric construction. The most basic fabrics are plain, twill and satin. Because these three organizations can change a variety of complex patterns, these three organizations are also called the original organizations:

Each plain weave construction contains only two warps and two wefts. Every other warp and weft in the fabric intersect. The fabric is the strongest and the fabric surface is flat because the warp and weft of this structure are the most frequent and closely related. The function is the same before and after. Fine cloth, poplin and varnish are all part of the organization. Most of the hotel sheets are woven in plain weave.

Twill weaving requires at least three warp and weft threads per cycle. It is characterized by a tissue point (or latitude) tissue point (a small piece floating on cloth) that forms an oblique texture that is a right diagonal from the lower left corner to the upper right corner. The lower right is called the left diagonal. Since the ratio of warp to weft is smaller than the ratio of plain weave, the density of warp and weft can be higher than the density of plain weave, so the fabric is thicker, denser and more shiny than plain weave. Yoshi, since the warp and weft are longer than plain weaves, it has a soft touch and excellent elasticity. However, robustness is unusual. The functions of the front and back of the twill fabric are opposite. If the front is diagonally right, the back is diagonally left. Hehuada is a twill weave.

Each cycle of satin weave has at least five warp and weft threads, and the floating points (or weft threads) are separated from each other by a twill weave. The surface of the fabric is covered with a long set of floating threads without showing another set of threads. The front and back of the fabric are clearly different. The front is particularly smooth and shiny, and the back is light and soft. The hand feels softest because it is rough and the intersection of the warp and weft is the least of the original three tissues, but the strength is minimal and there is no abrasion or cleaning. Bedspreads and tablecloths are often used in this organization.
