Because most of them are by-products of oil eg.nylon, polyester
Synthetic fabrics normally are made from polyester, which is a petroleum based,
Natural fibers such as cotton, linen, and silk burn more readily than other materials (silk being the most flammable). Synthetic materials like nylon, acrylic, and polyester do not ignite as readily as natural fibers but when they do ignite they melt causing severe burns. Natural and synthetic blends could be the most dangerous with the combination of high rate of burning and melting making it more hazardous than either fabric alone.

Most are synthetic chemicals but you can find natural cleaning solutions like Mrs. Meyers also..they are more expensive though.
Wash fastness? Perhaps you mean color fastness? If that is the case, color fastness is the ability of fabrics to retain the dyes used to color them. Some fabrics hold dye within their fibers extremely well - like denim - while others do not (mostly synthetic or artificial non-natural fabrics) and tend to "bleed" when they are washed. The denim would therefore be more "color fast" than the other fabric.

Most synthetic fabrics do not wrinkle easily. Synthetic fabrics have the capacity to hold more loads.This is called Tensilestrength .

A Natural FabricA natural fabric is made through only non-synthetic material, which means it is completely pure, and does not use manufactured materials.....Natural fabrics are collected through many different Land creatures, or plants...such as; Wool-it comes from sheep- Cotton-it comes from a plant-and there are more...
Probably because cotton is a natural fibre. It doesn't make people sweat like synthetic fabrics do, and thus is more comfortable to sleep on.
These cloths are more flammable.
natural rubber is more elastic than synthetic rubber
natural fabric a sobs more water the synthetic fabric. natural fabric is natural plants. synthetic fabric is man made.
Making clothes on the cheap is largely about the fabrics purchased. Synthetics are the best option because natural fabrics will cost more than those with a higher than 20 percent synthetic fabric count. Polyester is the best option for this.
Synthetic fibers

The synthetic fibers have their origin in the oil (petroleum) and their processes pollute the enviroment. In the other hand, the natural fibers increase the costs of the food and decrease the wildforest parks. One solution is to recycle the cotton, the plastics and reduce the production of the oil products including the fabrics. There is a new fabric from Dupont made of corn, also the ancient fabrics like Henequen, papire, linen, organic cotton and rayon (celluloise) are more requested by the Fashion Industry for clothing, home decoration and rugs for cars. Another benefit is to have a healthy body, because the natural fabrics permits a natural transpiration.
