Textile Engineering Interview Questions and Answers
Question - 51 : - What is elastic recovery?
Answer - 51 : -
The ratio of elastic extension to the total extension of a specimen is termed elastic recovery.
Question - 52 : - What is specific flexural rigidity?
Answer - 52 : -
The ratio of the flexural rigidity to the linear density is known as flexural rigidity.
Question - 53 : - What is the shape factor?
Answer - 53 : -
The quantity which determines the shape of the material is known as the shape factor. If the shape factor is 1 then fiber will be completely found.

Answer - 54 : -
The behavior shown by the materials when it is subjected to a torsional force is known its torsional properties.
Question - 55 : - What is bending recovery?
Answer - 55 : -
Recovery from a given curvature is known as bending recovery.
Question - 56 : - What is bending modulus?
Answer - 56 : -
The ratio of bending stress and bending strain is known as bending modulus.
Question - 57 : - What are frictional properties?
Answer - 57 : -
The property is shown by the fiber due to the friction when processing is termed as frictional properties.
Question - 58 : - What is swelling?
Answer - 58 : -
Swelling may be expressed in terms of the increase of diameter, area, length, or volume of fiber due to absorbing water.
Question - 59 : - What is a refractive index?
Answer - 59 : -
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is known as the refractive index.
Question - 60 : - What is torsional rigidity?
Answer - 60 : -
The ratio of torque unit twist per unit length is known as torsional rigidity.
