How you make paper white?
Paper is made of cellulose fiber. In pure form cellulose fiber is colorless but due to the presence of residual lignin, pulp obtained from wood is brown. Pulp is made white by removing and/or modifying lignin and this process is called bleaching.
How was fiberglass discovered?
Fiberglass was not discovered, it was invented. Plastic resins are often too brittle or two elastic to be usable for many purposes. Glass fiber is very strong and does not stretch but breaks when flexed. By laying out alternating layers of glass fiber oriented in different directions then saturating this glass fiber mesh in plastic resin you create fiberglass, a composite material that is stronger and more durable than either of the materials used to make it. Fiberglass was the first composite material invented. Note: wood is a natural composite material that trees have been making for hundreds of millions of years before there were humans; wood was discovered because it existed before we knew about it.
Why some fibres are called synthetic?
Synthetic fibres are man-made - polyester, nylon, rayon etc.. The alternative is natural fibres - cotton, wool, silk, jute etc.Technically rayon is a regenerated cellulose fiber. It's chemical composition is the same as wood or cotton but it has been processed so extensively that many people would call it a "synthetic" fiber.
Who invented wood fiber paper?

What wood is best wood pulp or fiber wood?
Wood pulp is typically preferred over fiber wood for making paper due to its shorter fibers, which help create a smoother and more uniform paper surface. Fiber wood, on the other hand, is better suited for applications requiring longer and stronger fibers, such as in construction materials. Ultimately, the choice between wood pulp and fiber wood depends on the specific needs of the end product.
How can you tell if wood is about to break?
When the wood is about to break the fiber of the wood on the edge from where is about to break emerge from the center and you get to know that it is about to break.
