How is the tensile strength of a fibre determined?
To determine the tensile strength of any fibre, it is tied to a hook at one end and weighted are slowly added to the other end until the fibre break. Since peptide bonds are more easily hydrolyzed by bases than acids therefore wool and silk are affected by basis not by acids.

Which is the most important property of a fibre?
Besides their chemical composition and properties, most important property of these fibres is their tensile strength. Tensile strength mean the extent to which a fibre can be stretched without breaking and it is measured in terms of minimum weight required to break the fibre.
Why do acids decrease the tensile strength of vegetable fibres?
Since ethers are hydrolised by using acids and now not by way of bases consequently, vegetable fibres are suffering from acids however no longer through bases. In other phrases acids decreases the tensile strength of vegetable fibres.
