Nylon, any synthetic plastic material composed of polyamides of high molecular weight and usually, but not always, manufactured as a fiber. Nylon is a generic designation for a family of synthetic polymers composed of polyamides (repeating units linked by amide links). Wool, along with cotton and to a lesser extent nylon, is a fibre that absorbs moisture from the surrounding air to reach an equilibrium, which depends on the relative humidity of the environment. These materials make up the objects around us, and each of these materials has different properties or characteristics that can be observed or tested. It provides enhanced chemical and heat resistance. The material is available as homopolymer, co-polymer, or reinforced. These yarns are also not recommended for aeronautical applications such as in parachutes, para-gliders and hot-air balloons. Jul 1 Listen, my child, these words of indescribable courage which is characteristic of love is the love that the Son of man shall humble themselves, serves, teaches, heals, nourishes, refreshes, straightens and heads, gives joy, let torment, suffering, forgiving and dies.

As these units increase in length, making the molecules appear more like polyethylene, the properties of the nylon shift slightly toward those of polyethylene. At ambient humidity, wool will contain 10 to 15% by weight of water and up to 35% water at high relative humidity, which is more than most other fibres. Cotton fabrics are best worn in hot and humid conditions as these clothes absorb sweat and evaporates it thus, making the body cool. Nylon 6/6 has a yield strength of 6500-8500 psi.
