Top Questions For Textile Engineer Job Interview
Textile Interview Questions and Answers:
The major textile interview questions and answers have presented below:
1. What is the load?
The application of a load to a specimen in its axial direction causes 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 mass stress.
3. What is a strain?
The ratio of elongation to the initial length of a specimen is termed a strain.
4. What is elastic recovery?
The ratio of elastic extension to the total extension of a specimen is termed elastic recovery.
5. What is bending recovery?Recovery from a given curvature is known as bending recovery.
6. What is bending modulus?
The ratio of bending stress and bending strain is known as bending modulus.
7. What are frictional properties?
The property is shown by the fiber due to the friction when processing is termed as frictional properties.
8. What is swelling?
Swelling may be expressed in terms of the increase of diameter, area, length, or volume of fiber due to absorbing water.
9. What is a refractive index?
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is known as the refractive index.
10. What is specific flexural rigidity?
The ratio of the flexural rigidity to the linear density is known as flexural rigidity.
11. What is the shape factor?
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.
12. What are torsional properties?
The behavior shown by the materials when it is subjected to a torsional force is known its torsional properties.
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 in a glass and the brittle condition is known as glass transition temperature. It is denoted by Tg. The range of Tg for the 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 presses index?
The ratio of breaking load in a pound of fiber to the weight of fiber in MGM is termed as Pressley’s index (P.I).
18. What is textile testing?
The process of determining the characteristics of textile products is known as textile testing.
19. What is sampling?
The process by which a sample is collected from a large number of materials is termed 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 the 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 the material are 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 souring?The treatment by which the fabric after processing with scouring is stated with dilute sulphuric acid for removing alkali is known as souring.
