Textile Question Bank:
A textile engineer should have clear concept (basic concept) about all the sector of textile. If he has, then it’s easy to manage his dream job. To fill up your basic concept this article has presented here some frequently asked textile interview questions with their answers which will be very useful in your upcoming interview.
Textile Interview Questions and Answers:
The major textile interview questions and answers have presented in the below:
1. What is load?
The application of a load to a specimen in its axial direction causes a tension to be developed in the specimen. The load is usually expressed in gm-wt or pounds.
2. What is mass stress?
The ratio of the force applied to the linear density is termed as mass stress.
3. What is strain?
The ratio of elongation to initial length of a specimen is termed as strain.
4. What is elastic recovery?
The ratio of elastic extension to the total extension of a specimen is termed as elastic recovery.
5. What is specific flexural rigidity?
The ratio of the flexural rigidity to the linear density is known as flexural rigidity.
6. What is shape factor?
The quantity which determines the shape of material is known as shape factor. If shape factor is 1 then fiber will be completely found.
7. What are torsional properties?
The behavior shown by the materials when it is subjected to a torsional force is known its torsional properties.
8. What is bending recovery?
Recovery from a given curvature is known as bending recovery.
9. What is bending modulus?
The ratio of bending stress and bending strain is known as bending modulus.
10. What are frictional properties?
The property shown by the fiber due to the friction when processing is termed as frictional properties.
11. What is swelling?
Swelling may be expressed in terms of the increase of diameter, area, length or volume of a fibre due to absorbing water.
12. What is refractive index?
The ratio of sine of angle of incidence to sine of angle of refraction is known as refractive index.
13. What is torsional rigidity?
The ratio of torque unit twist per unit length is known as torsional rigidity.
14. What is glass transition temperature?
The temperature at which the fiber behaves as a glass and brittle condition is known as glass transition temperature. It is denoted by Tg. The range of Tg for linear polymer is 100°C to 300°C.
15. What is thermal conductivity?
It is the rate of transfer of heat along a body by conduction. The higher value of thermal conductivity, the fiber will then more conductive.
16. What is melting temperature?
The range of temperature at which the fiber melts is known as melting temperature. It is denoted by Tm.

17. What is pressleys index?
The ratio of breaking load in pound of a fiber to the weight of fiber in mgm is termed as pressleys index (P.I).
18. What is textile testing?
19. What is sampling?
The process by which a sample is collected from a large number of materials is termed as sampling.
20. What is relative humidity?
The ratio of the actual vapor pressure to the standard vapor pressure at the same temperature express as a percentage is known as relative humidity.
21. What is standard temperature?
An atmosphere at the prevailing barometric pressure with a relative humidity of 65% and temperature of 20°C (68°F) is known as standard temperature.
22. What is quality control?
The checking verification and regulation of the degree of excellence of an attribute or property of material is known as quality control.
23. What is testing temperature?
The atmosphere with a relative humidity of (65% ± 2%) and temperature of (20°C ± 2°C) or (68°F ± 4°F) is known as testing temperature.
24. What is pitch?
Tip to tip of teeth distance is known as pitch.
25. What is souring?
The treatment by which the fabric after processing with scouring is stated with dilute sulphuric acid for removing alkali is known as souring.
