what is the tensile strength of wool, nylon ,terylene and rayon
Answers
Answer:
What is the tensile strength of silk, cotton, nylon and wool?
Tensile strength is the measure of the maximum resistance of longitudinal stress before it breaks.The different properties of each fibre depends upon the source and orientation of that particular fibre. There are different properties of fibre like absorbent nature,strength,chemical resistance,crimp etc.Among these tensile strength is an important parameter since the fibres are supposed to exposed to tension and stress during subsequent stages of making yarn ,fabric and then clothing.Even the functionality and wear and tear of particular clothing depends upon this vital property.
Silk:Silk has good tensile strength, which allows it to withstand great pulling pressure. Silk is the strongest natural fibre and has moderate abrasion resistance. 2. Elongation at break: Silk fibre is an elastic fiber and may be stretched from 1/7 to 1/5 of its original length before breaking.
Cotton: Cotton is moderately strong fibre. It has a tenacity of 3-5 gm/den. The strength is greatly affected by moisture; the wet strength of cotton is 20%, which is higher than dry strength.
Nylon: The high tensile strength of nylon makes it ideal for heavy fabrics used in home decor.Tensile Strength, Ultimate 82.7 MPa,Elongation at break is 50 %.Tensile Modulus 2.93 GPa.
Wool:The tensile strength of wool in dry condition is 1 – 1.7 and 0.8 – 1.6 in wet condition. Elongation at break, Standard elongation is 25 – 35% and 25 – 50% in wet condition.
Rayon-The Tensile Strength of rayon fibre is less when the fibre is wet than when dry. It is 1.5-2.4 gpd in the dry state and 0.7-1.2 gpd in the wet state. For high tenacity variety the values are 3-4.6 gpd and 1.9 to 3.0 gpd. The elasticity of Viscose Rayon is less than 2-3%.
