Several factors contribute to the shrinkage of rubber, including exposure to heat, sunlight, and certain chemicals. Additionally, mechanical stress and aging can also cause rubber to shrink over time.
The normal shrinkage percentage of khadi after the first wash is usually around 5-10%. It is recommended to follow the care instructions provided by the manufacturer to minimize shrinkage.

Yes, although sometimes not noticeably enough to notice. Different types of rubber would experience different shrinkage rates.
Rubber can shrink due to exposure to heat, solvents, or prolonged tension. Heat can break down the polymers in the rubber, causing it to contract. Solvents can dissolve components of the rubber, leading to shrinkage. Tension can alter the molecular structure of the rubber, causing it to compact.
Lead has a high shrinkage rate due to its high density and low melting point. The shrinkage percentage of lead varies depending on the specific alloy composition and cooling rate used during the casting process. In general, lead can experience shrinkage of around 2-4% when it solidifies after being molten.
Residual shrinkage in woven fabrics refers to the amount of shrinkage that occurs after the initial washing or treatment. This is typically measured by comparing the dimensions of the fabric before and after washing, and the residual shrinkage percentage indicates how much the fabric will continue to shrink with subsequent washes. Residual shrinkage is important to consider when evaluating the suitability of a fabric for specific uses or applications.
