it is better to use natural materials
the disadvantages of natural fibres are the followingabsorbs a lot of waterlow staticfades faster (colour loosing)some natural fibres are very delicate like silk and are hard to wash/dry etcto produce natural fibre lots of land is requiredshrinking
Polymers are used in our lives as polythene is used in shopping bags, They are used in for different things as-well, for example NYLON in suitcases and bags Polyvinyl-acetate in plastic bottles and utensils There are many Different Polymers The clothes we were are made out of polyester
Rockets are typically constructed using materials such as aluminum, titanium, carbon fiber, and stainless steel for the main structural components. These materials offer a balance of strength, durability, and lightness essential for spaceflight. Additionally, various heat-resistant materials and thermal protection systems are used to protect the rocket from the extreme temperatures experienced during launch and re-entry.
The chemical processes that build up materials in organisms are called anabolic processes, while the processes that break down materials are called catabolic processes. These processes are essential for maintaining the balance of molecules within an organism for growth, repair, and energy production.
Inexpensive shoes often use lower quality materials that don't breathe well, leading to a build-up of moisture and bacteria that cause odor. Brand name shoes typically use higher quality materials and construction that allow for better ventilation, reducing the chances of odor accumulation.
The Kayapo's houses are made from natural materials, i don't quite know what materials but they are definitely things like wood etc.
Because you can design a synthetic polymer to exactly meet your needs. You can modify a natural polymer sometimes if it's not what you need, but at that point is it really a "natural" polymer? Take cellulose--a perfectly serviceable natural polymer, they build millions of homes every year out of it. But what if you need a polymer you can see through? Cellulose won't work for you there unless you dissolve it in acetic acid (cellulose acetate) or nitric acid (cellulose nitrate). By the time you're done, you have a polymer that's no longer really "natural."
Louis Kahn's materials of choice to build with included exposed concrete, brick, and wood. He believed in using natural materials that could create a sense of warmth and timelessness in his architecture, emphasizing honesty in the way materials were used and expressed.
Concrete, Mortar, Brick, Block, Re bar for support
You are most likely to build up enough static charge to experience a force when rubbing certain materials together, such as textiles like wool and synthetic fabrics, plastic, or rubber. This friction between materials can lead to the transfer of electrons and build up static electricity.
Squirrels build their nests, called dreys, by weaving together twigs, leaves, and other natural materials. They construct these nests high up in trees to keep them safe from predators and the weather.
They use Dirt, Mud, Stone, and other natural materials near them.

To build an irrigation system you will need clay,sand or soil (optional), plastic leaves,glass and other natural materials.
The longest lasting material for a deck is also the most expensive. IUt involves the use of synthetic materials. They can be made of plastic, vinyl or wood-polymer lumbers. They also come in a variety of colors. And all these materials need to be installed using a base of pressure treated wood.
The materials are the following:woodstonedirtgold
