1. ____________ refers to the appearance or feel of the paper’s surface.
a) Deckle
b) Curl
c) Watermark
d) Finish
Explanation: Finish refers to the appearance or feel of the paper’s surface.
2. The ____________ is the side of the paper formed against the moving wire of the paper machine.
a) Felt side
b) Wire side
c) Cockle
d) Deckle
Explanation: The wire side’s the side of the paper formed opposite to the moving wire of the paper machine. Paper formed on twin wire machines has two wire sides.
3. The ____________ is the opposite side of the paper from the wire side.
a) Sizing side
b) Felt
c) Cockle
d) Deckle
Explanation:The felt side’s the opposite side of the paper from the wire side for paper from single wire machines.
4. Paper tends to be stiffer and stronger in the machine direction than the cross machine direction.
a) True
b) False
Explanation: Paper tends to be stiffer and stronger in the machine direction than the cross machine direction acc. to T.A.P.P.I. Standard T 409 lists methods for determining the machine direction of paper and paperboard.
5. The strength of wood and paper depends upon the rate of unloading.
a) True
b) False
Explanation:The strength of wood and paper and any material depends on the rate of loading as quickly the force crucial a relatively large load can be supported for a short period of time.
6. The tensile index obtained by dividing the tensile strength by the basis weight and breaking length are alternate means of reporting __________ where the basis weight is normalized.
a) Tensile strength
b) Stress
c) Strain
d) Resistive force
Explanation: The tensile index obtained by dividing the tensile strength by the basis weight and breaking length are alternate means of reporting tensile strength where the basis weight is normalized.
7. The __________ which is also called the Mullen strength, measures the value of hydrostatic pressure which crucial at a specified rate but required to rupture a piece of paper.
a) Mullen tester
b) Burst strength
c) Captative strength
d) Entity strength
Explanation: The burst strength, which is also called the Mullen or pop strength, measures the value of hydrostatic pressure which is crucial at a particular rate.
8. What is the name of the hidden part?
___________=(psi) / (lb/ream)
a) Ratio
b) Factor
c) Burst
d) Index
Explanation: The burst can also be calculated in units of pound per square inch divided by lb per ream to give the burst ratio.
9. The __________ of paper gives values same as that of ring crush tests. The results is co-rrelated with tensile and burst strengths of paper.
a) Ediwise compression strength
b) Edgewise comparative strength
c) Ediwise comparative strength
d) Edgewise compression strength
Explanation: The short span compression or edgewise compression strength of paper gives values similar to those of ring crush tests. The results are co-rrelated with the tensile and burst strengths of paper. It’s very crucial in predicting how will a corrugated box will perform with a particular linerboard.
10. The __________ measures the energy required to propagate an initial tear through a lot of sheets of paper for a fixed distance.
a) Fold endurance
b) Abrasion factor
c) Internal tear resistance
d) Outer tear resistance
Explanation:The internal tear resistance measures the energy required to propagate an initial tear through a lot of sheets of paper for a fixed distance. The value is used in g-cm/sheet.
