Twill is fabric that has a diagonal pattern. It is actually woven in such a way as to create diagonal "ribs" in the fabric itself (not just colored diagonal lines). Think of cordoroy - that is a fabric with a vertical (up and down) pattern woven into it. Twill is diagonal weaving. If a twill fabric has extra "give" so that it can expand (stretch), it is a stretch twill.
Stretch twill often refers to the fabric having a small percentage of lycra/spandex in it, usually 2-4%.
twill is a very rough fabric that comes from elephants.
fabric strength and durability
Bottom weight twill is a type of fabric that is heavier and stronger than its top weight counterpart. It is often used for making durable bottoms such as pants, skirts, and jackets. The diagonal weave of twill fabric gives it a distinctive texture and a good amount of stretch, making it a popular choice for clothing that requires both comfort and durability.
A twill jersey is a type of sports uniform that is made of twill. Twill is a woven fabric with a ribbed pattern that is diagonal and parallel.
A zanella is an Italian wool or twill fabric.
A ribbed fabric is a fabric with intervening raised lines or ribs. Ribbed fabrics may come in a variety of compositions including cotton, wool and silk.
Uneven twill is a type of fabric weave pattern where the twill line is not perfectly diagonal, resulting in an irregular and uneven appearance. This creates a unique and aesthetically pleasing texture in the fabric. Uneven twill can be found in various textiles such as denim and other heavy-weight fabrics.
Twill fabric can be soft and airy or thick and warm, depending on the thread count and the method of weaving.
The easiest way to identify a twill weave is if the fabric appears to have a diagonal "texture"- this is caused by the offset of weft and warp threads when the fabric is woven (for example, over once, under twice. As opposed to over once, under once as a normal weave). The grain of the fabric is not actually diagonal, but the twill weave gives it that appearance.
Cotton
Coarse twill is a type of fabric weave characterized by prominent diagonal lines or ridges. It is woven using a basic twill weave pattern with thicker yarns, resulting in a heavier and more textured fabric suitable for items like jackets, outerwear, and bags.
Twill fabric has a diagonal ribbed texture created by weaving the threads in a specific pattern, while poplin fabric has a smooth, plain weave. Twill fabric is typically more durable and heavier, while poplin is lightweight and breathable, making it suitable for dress shirts and blouses.
