Spandex is the answer. So a woven fabric comprised of 95% polyester and 5% spandex will stretch somewhat in both directions and slightly more on the bias. A tricot knit consisting of 95% polyester and 5% spandex will stretch a lot. It can be used for fashion clothing and underwear.
Polyester-spandex (85/15) blends When mixed with cotton, spandex creates a fabric that is both pleasant to the touch and long-lasting. Spandex also makes clothes move with you if you exercise or dance like a disco ball.
5% of its weight is spandex. 10% is polyester. 20% is nylon. 50% is cotton. 100% is polyester.
Spandex is a synthetic fiber that can be used on its own or in combination with other fibers. It's very flexible but still has some strength. It was originally developed for clothing but now it's also used for sporting goods such as biking shorts and running shoes.
Spandex comes in different colors and styles of knitting that can be used to create fabrics for clothing. The most common type of knitting used to make spandex is called "tricot". Tri- means three - and cot means cotton. Tricot is usually 95% polyester and 5% spandex. However, it can be made from other materials including 70% polypropylene and 30% spandex.
Tricot is knitted by first making a tube. Then the tube is narrowed into two parts that are joined at the crotch line.
Obviously, because spandex fiber is included, it will stretch. In general, 1% to 3% spandex is used with polyester fabric to create a stretch blended fabric or garment. This type of clothing has a poor dimensional stability. Polyester spandex is a textile that is stretchable. It is made by combining polyester fibers with spandex fibers.
Woven cloth is typically crisp and non-stretchy. It might be as light as chiffon or as heavy as denim. Some woven textiles, such as stretch denim and stretch poplin, contain spandex woven into them to provide stretch. These fabrics are usually labeled as such if they're made in China, although they may be called knitwear if made in America.
Woven fabrics are created by taking a warp (the horizontal thread) and weft (the vertical thread) and repeating the same process over and over again. The finished product is flat with loops on one side and strands on the other. There are several different methods used for weaving fabric. Each method has its advantages and disadvantages. Which method is used depends on what effect you want to create in the final product. For example, if you want your weave to look like basketweave, then a simple drop weft (one down through every row of threads) would be enough. But if you also want some of the threads to appear on top of others, then a jacquard machine is needed.
The warp threads are held up by a heddle frame, which can be hand-operated or motorized. As the operator turns a knob or pushes a button, the heddle frame raises or lowers the individual threads to either lift them out of the way or drop them down onto the loom. This creates the pattern.
Spandex can stretch up to 400% of its original size on its own, but when combined with other materials, it can still provide up to 20% of its elasticity to the associated fiber. Polyester, Cotton-Spandex, Nylon, and stretch velvet are some of the most prevalent spandex mixes on the market, although there are several different variations. The best way to determine which material is right for you is by experimenting with samples in store. There's no such thing as a bad fabric as long as you don't mind spending a little more money to get something that feels better.
Stretching polyester causes it to lose some of its strength, so if you plan to use it for clothing or other projects where this might be an issue, try not to stretch it too much. Spandex adds softness and flexibility to fabrics it's mixed into, so if you're looking for a softer feel, look for fabrics containing both spandex and polyester or nylon. If you want a stronger feeling fabric that will hold its shape, go for pure polyester or nylon instead.
There are two types of spandex: natural and synthetic. Natural spandex comes from the silk industry and is usually a combination of polymers produced from petroleum products. It can be white or black in color and has excellent stretching properties. Its main disadvantage is that it tends to be expensive. Synthetic spandex is made by polymerizing monomers into chains that can be manipulated into any shape you like.
