Classtest TFY 24

It is essential to give coherence and strength to staple fibre yarns during spinning

• Sizing

• Binder

• Twist

• Texturising

The stelometer works on this principle of tensile testing

• CRE

• CRT

• CRL

• CRM

Which of the following does not follow the pendulum lever mechanism for tensile testing

• Stelometer

• Lea strength tester

• UTM

• Pressley strength tester

Which of the following is not the correct unit for breaking force

• gram

• Newton

• kilogram

• gf/Tex

Which of the following strength test reflects upon the weavability of the yarn

• Fibre bundle strength

• Lea CSP test

• Single yarn strength

• Single fibre strength

Identify the instrumnt that works on beam balance principle

• Stelometer

• Vibrodyne

• Pressley bundle strength tester

• Lea strength tester

As we increase the twist in the staple yarn, its strength

• increases

• decreases

• first increases and then decreases

• first decreases and then increases

For the same yarn count of staple spun yarn, if Twist Multiplier is increased from 3.2 to 3.8, the turns per inch in the yarn would

• increase

• decrease

• first increase and then decrease

• remain unchanged

If the Twist multiplier is 4.0 for the following spun yarns, which one of the following will have the highest turns per inch

• 16 Ne

• 25 Ne

• 36 Ne

• 64 Ne

All the given yarn counts tested have a breaking force of 2400 gf. Pick the count which is the weakest

• 20 tex

• 30 Tex

• 60 Tex

• 80 Tex
