In this type of weave 'weft' is woven after regular intervals of 'warp' yarn in such away that diagonal pattern is created:

Question

Accepted Answer

The correct option is 2:

Twill weave is one of the three fundamental textile structures, and its defining characteristic is the formation of a visible diagonal rib, or "wale," on the surface of the fabric. This diagonal pattern is exactly what the question describes and is achieved through a specific and consistent method of interlacing the warp and weft yarns. The weft yarn is woven over one or more warp yarns and then under two or more, and this interlacing point is shifted one warp end over in each successive row, creating a progressive "step" in the pattern. This systematic offset is what distinguishes the twill from other basic weaves and creates the slanting diagonal line, which can run either from right to left (S-twill) or left to right (Z-twill). The structure of the twill weave allows the threads to be packed closely together, making the resulting fabric dense, highly durable, and excellent at concealing soil and wrinkles. Familiar examples of twill-woven fabrics include sturdy materials like denim, gabardine, and chino.

The incorrect option is 4: Plain

The plain weave is the simplest and most basic form of textile construction, also known as the tabby weave. This weave is created by a simple, balanced interlacing pattern: each weft thread passes alternately over one warp thread and under the next. This consistent "over-one, under-one" construction repeats in every row, resulting in the maximum number of interlacements and a highly stable, flat surface. The structure of the plain weave produces a checkerboard or basket-like texture with no pronounced diagonal lines. Because of its simple construction, the front and back of the fabric appear identical. Therefore, the plain weave does not match the description of a pattern created by diagonal interlacings.

The incorrect option is 3: Satin

The satin weave is easily identifiable by its glossy, smooth, and lustrous surface appearance. This effect is achieved because the weave is intentionally designed to produce long "floats," where the warp yarn passes over several weft yarns (typically four or more) before interweaving. The key structural feature of the satin weave is that these infrequent interlacing points are scattered and intentionally non-adjacent. This scattering prevents the formation of any visible diagonal line or wale. The primary focus of the satin weave is to create maximum light reflection and smoothness, contrasting sharply with the distinct diagonal texture of the twill weave.

The incorrect option is 1: Basket

The basket weave is considered a decorative variation of the basic plain weave, but it does not produce the characteristic diagonal pattern of a twill. In a basket weave, two or more adjacent warp threads are grouped and woven as one unit, and two or more weft threads are similarly grouped and woven as one unit. The most common form is the 2x2 basket, where two warp yarns weave over and under two weft yarns, following the simple plain weave sequence. This grouping of yarns creates a boxy, porous, or checkerboard-like pattern that is bulkier and more flexible than a plain weave. Since its structure is based on block units and lacks the one-step offset necessary to create a continuous diagonal line, it is not the correct answer.
