The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
How is a plastic rod is rubbed with silk?
When a plastic rod is rubbed against silk, electrons are transferred from one material to the other due to the difference in their electron affinity. This creates areas of positive and negative charge on the rod and silk respectively, leading to the attraction between them. This phenomenon is known as triboelectric charging.
Well it's a protein therefore there are 5 chemical elements within silk.
These elements being:
- Carbon

What was the rediscovery of the silk roads?
In the early 1900's, Sir Marc Aurel Stein, a British archeologist, set out to confirm his theories about rich past of the Silk Road. In three expeditions, Stein traversed 25,000 miles of central Asia and western China, thus gaining the reputation of conducting "the most daring and adventurous raids upon the ancient world".
Since the expeditions of Zheng He, the east-west trade had steadily increased, but the bulk of trade moved by sea. The oasis towns that had thrived with the silk trade faded from bustling and wealthy rest stops for merchants linking the core trade arteries of the Asia to secondary routes far from the traffic of the world.
In 1644, the Qing dynasty replaced an ailing Ming. The Qing made China once again strong along the Silk Road. But by the 1900's, the Qing too was failing and its control over western China was quickly slipping. Islamic groups who lived in this region managed the interior trade routes and farmed nd moved their herds with or without Chinese control. In a series of independence movements and armed revolutions, the people of far western China attempted to break away from Qing rule

What happens when you rub a balloon with silk?
When you rub a balloon with silk, electrons are transferred from the silk to the balloon, causing the balloon to become negatively charged and the silk to become positively charged. This process is an example of triboelectric charging, where different materials exhibit varying tendencies to gain or lose electrons. As a result, the charged balloon can attract lightweight objects or even stick to surfaces due to electrostatic forces.

It is used in clothing, yarns, decorative textiles, bed linens and fabric.
Silk's good absorbency makes it comfortable to wear in warm weather and while active. Its low conductivity keeps warm air close to the skin during cold weather. It is often used for clothing such as shirts, blouses, formal dresses, high fashion clothes, negligees, pyjamas, robes, skirtsuits, sun dresses and kimonos.
Silk's elegant, soft luster and beautiful drape makes it perfect for many furnishing applications. It is used for upholstery, wall coverings, window treatments (if blended with another fiber), rugs, bedding and wall hangings.
While on the decline now, due to artificial fibers, silk has had many industrial and commercial uses; parachutes, bicycle tires, comforter filling and artillery gunpowder bags.
From the blackpowder era, until roughly World War I, early bulletproof vests were made from silk.
A special manufacturing process which removes the outer irritant sericin coating of the silk makes it suitable as non-absorbable surgical sutures. This process has also recently led to the introduction of specialist silk underclothing for children and adults with eczema where it can significantly reduce itch.
Silk cloth is also used as a material on which to write and paint, and some silk fabric can be expensive.

Does a Giclee or a Silk-Screen have greater value?
A silk-screen (if it were in fact a 'silk' screen, another subject to be tackled, since silk has not been in use for this process in years) has more value than any machine printed artwork or form. Since the, (let's call this what it is)..serigraph..is produced by hand mostly, with each color applied and registered, time involving to create the right color balance, which could also involve color matching/mixing and test prints to create the final print. The Serigraph process will usually include a limited smaller run, since any machine output can be any number of 'limited' prints....and is automatic. The Serigraph print will and can last for years. Since the Giclee printing or ink really has absolutely no history, except for the past years that machines have been in use(1990's) no one can really say what the outcome is in 100 years. Silk-screen/Serigraph prints and posters have a proven history since one can peruse original posters in any art museum in the world.... Therefore the value is in "Silk-Screen'
