Textile Engineering Interview Questions and Answers
Question - 61 : - What is glass transition temperature?
Answer - 61 : -
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.
Question - 62 : - What is thermal conductivity?
Answer - 62 : -
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.
Question - 63 : - What is melting temperature?
Answer - 63 : -
The range of temperature at which the fiber melts is known as melting temperature. It is denoted by Tm.
Question - 64 : - What is presses index?
Answer - 64 : -
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).
Question - 65 : - What is souring?
Answer - 65 : -
The treatment by which the fabric after processing with scouring is stated with dilute sulphuric acid for removing alkali is known as souring.
Question - 66 : - What is pitch?
Answer - 66 : -
Tip to tip of teeth distance is known as pitch.
Question - 67 : - What is testing temperature?
Answer - 67 : -
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.
Question - 68 : - What is quality control?
Answer - 68 : -
The checking verification and regulation of the degree of excellence of an attribute or property of the material are known as quality control.
Question - 69 : - What is the standard temperature?
Answer - 69 : -
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.
Question - 70 : - What is relative humidity?
Answer - 70 : -
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.
