The breaking load of a cotton yarn, with a twist multiplier of 4 tpi·Ne-0.5, is 2.5 N. If the twist (number of turns per inch) of yarn is 20, then the tenacity (cN/tex) of the yarn (rounded off to 2 decimal places) is
Ques 54 GATE 2022
A three-bladed beater is running with an angular velocity of 600 rpm and delivering material at a rate of 600 kg/h. Number of strikes per kg of delivered material (in integer) is
Ques 55 GATE 2022
Keeping the speed of all other components of a carding machine unchanged, the angular velocity of a cylinder with damaged wire points in an area of 2 cm x 2 cm is doubled. Wavelength of the periodic fault in the card sliver would be _______ cm.
Ques 56 GATE 2022
In a comber, the component that rotates both in the forward and backward directions is
Ques 57 GATE 2022
The machine that uses 'Horn gears' is
Ques 58 GATE 2022
Assume that there is no compression of roving during winding and each coil of a layer is placed directly over the coil of the previous layer. A full roving bobbin consisting of 50 layers of roving is wound on an empty bobbin of 60 mm diameter. If the diameter of the roving is 1 mm, then the diameter (mm) of the full bobbin (in integer) is
Ques 59 GATE 2022
Determine the correctness or otherwise of the following Assertion [a] and Reason [r].
[a]: As compared to parallel wound yarn packages, ring bobbins exhibit lower tendency of slough off during unwinding
[r]: The main winding layers in the ring bobbins are separated by cross-winding layers
Ques 60 GATE 2022
A set of yarns is produced with same linear density. If these yarns follow helical model and their diameter is inversely proportional to twist (number of turns per unit length), then the yarns have the same
Ques 61 GATE 2022
Yarn that has helically twisted fibres at the core and belts/wrappers on the surface is
Ques 62 GATE 2022
A monofilament gets extruded at a speed of 10 m/min from a spinneret of 0.2 mm diameter. In order to ensure a spin draw ratio of 11, the first godet roller with a diameter of 70 cm has to rotate with an angular velocity (rpm) of (rounded off to nearest integer)
Ques 63 GATE 2022
Nine slivers having same mean linear density are doubled on a drawframe. If the standard deviation of linear density of each sliver is 0.3 ktex, then the standard deviation (ktex) of linear density of the doubled sliver (correct up to 1 decimal place) is
Ques 64 GATE 2022
The twist angle (degree) of surface fibres in a yarn with density of 700 kg/m3 and twist multiplier of 6000 m-1·tex0.5 (rounded off to nearest integer), is
Ques 65 GATE 2022
In a multiplicative type tensioner, the angle of wrap is 90° and the coefficient of friction between the yarn and the guide is 0.2. If the input yarn tension is 10 cN, then the output yarn tension (cN) is (rounded off to 1 decimal place)
