GATE 2024 Textile Engineering and Fibre Science Question Paper with Solution
| Serial No. | Question | Answer | Solution |
|---|---|---|---|
| Q.1 | If '→' denotes increasing order of intensity, then the meaning of the words [dry → arid → parched] is analogous to [diet → fast → ________]. | (A) starve | The sequence represents increasing intensity of food intake. "Diet" → controlled intake, "Fast" → abstaining, and "Starve" → extreme deprivation. |
| Q.2 | If two distinct non-zero real variables x and y are such that (x + y) is proportional to (x − y), then the value of xy. | (D) is a constant | From the proportionality, it can be concluded that x and y have a definite relationship that maintains their product constant. |
| Q.3 | The median of the sample: 9, 18, 11, 14, 15, 17, 10, 69, 11, 13. | (A) 13.5 | List in ascending order: 9, 10, 11, 11, 13, 14, 15, 17, 18, 69. Middle value = (13 + 14)/2 = 13.5. |
| Q.4 | Percentage of money in ₹5 coins. | (C) 10% | Total coins: 21x. Total amount = ₹150x, amount in ₹5 coins = ₹15x. Percentage = (15x/150x) × 100 = 10%. |
| Q.5 | Value of p⁴ + q⁴ / p²q². | (B) 81 | Given log equation simplifies to p² + q² = 81pq, leading to p⁴ + q⁴ = 81p²q². |
| Q.6 | Pick out the most appropriate substitute for all the blanks. | (A) (i) down (ii) down (iii) on (iv) for | The correct phrases retain the flavor of keeping one's cool while batting. |
| Q.7 | Ratio of the volume of the cylindrical tube to the volume of the cube. | (B) 2/π | Cylinder volume = πr²h; cube volume = s³. Ratio derived from given dimensions. |
| Q.9 | Final folded sheet's perimeter. | (C) 20 | Each fold reduces the dimensions; final perimeter calculation gives 20 cm. |
| Q.11 | Simpson's rule approximation of the integral. | (B) 0.19 | Simpson's rule applied gives the integral's value as approximately 0.19. |
| Q.14 | Polymer having the lowest glass transition temperature. | (A) Polyethylene | PE has the lowest Tg due to its flexible structure. |
| Q.15 | Fibre forming polymer by chain growth polymerization. | (C) Polyacrylonitrile | PAN is synthesized through chain growth polymerization. |
| Q.16 | Purpose of opening in blowroom. | (A) Individualisation of fibres in tufts | This process separates and aligns fibres. |
| Q.17 | Forward and reverse rotary motion in cotton combing. | (B) Cylinder comb | The cylinder comb operates with this motion. |
| Q.18 | Circumference of the shrunk tubular fabric. | (B) 56.2 | Calculated circumference after 35% shrinkage. |
| Q.19 | Winder's yarn winding time. | (A) 68 | Calculated for the speed factor and efficiency. |
| Q.20 | Fabric bending length relationship to overhanging length. | (B) C = 0.5 L | This represents the correct relationship at the specified angle of deflection. |
| Q.21 | Evenness tester measures. | (C) Coefficient of variation of mass per unit length of yarn | Only appropriate measure for yarn's evenness test. |
| Q.22 | Chemical used for bleaching cotton in acidic medium. | (A) NaClO2 | NaClO2 is employed for bleaching in the acidic medium. |
| Q.23 | Choice of dyes in discharge printing. | (C) LD can be applied only as ground colour and HD can be applied only as illuminant colour | Correct application based on dischargeability properties. |
| Q.24 | Nitrogen-bearing fiber(s). | (A) Nylon 6, (B) Kevlar, (C) Acrylic | All three are nitrogen-bearing fibers. |
| Q.25 | Components whose velocity is not constant. | (B) Bobbin | Speed varies with package build-up. |
| Q.26 | Conditions that would reduce bumping during weaving. | (B) Reduction in sweep of the sley | Correct conditions identified. |
| Q.27 | Measurement principles for yarn hairiness. | (A) Measurement of length of hair is by the principle of light scattering, (D) Count of hairs is measured by photocells | Correct statements about measurement principles. |
| Q.28 | Statements related to fluorocarbon-based soil release finish. | (A) In dry condition, hydrophobic blocks shield the hydrophilic blocks to repel soil, (B) Upon wetting, the hydrophilic blocks swell, making it easy to release soil | Both statements correctly describe the finish behavior. |
| Q.31 | Degree of polymerisation for PET with molecular weight 25000. | 130 | Degree of polymerisation = Molecular weight / Monomer weight = 25000 / 192 (approx.) = 130. |
| Q.32 | Count of polyester yarn replaced with cotton yarn. | 22.02 | Using density ratios, calculate new tex count: (20 * 1.52 / 1.38) = approx. 22.02. |
| Q.33 | Areal density of knitted fabric. | 133 | Areal density = (count × loop length × courses/cm × wales/cm) converted to g/m² = approx. 133. |
| Q.34 | Resultant count of 3-ply yarn. | 36.74 | Use the formula for the combined count based on twist and composition. |
| Q.35 | Energy for drying the fabric. | 1232 | Calculate using the formulas for specific heat and latent heat energy = approx. 1232 kCal. |
| Q.36 | Value of x based on the characteristics of the matrix eigenvalues. | (C) 2 | Solve for x based on conditions for eigenvalues. |
| Q.37 | Root of the equation using Secant method. | (C) 0.65 | Using Secant method formula, get approx. 0.65. |
| Q.38 | Assertion and Reason correctness about Nylon 6. | (D) [a] is true but [r] is false | Moisture influences properties, but not directly the requirement for drying. |
| Q.39 | Assertion and Reason correctness about cotton. | (A) Both [a] and [r] are true and [r] is the correct reason for [a] | Cotton's behavior in flame is due to its lack of crystalline structure. |
