Amongst the following, the correct statement(s) is/are Textile Processing- MOCK Test 1 Assuming Beer-Lambert law is applicable for dilute solutions, if the molar concentration of dye in the solution is doubled then the percentage increase in absorbance would be The Gibb’s free energy equation for a system undergoing phase transition is given by ΔG = ΔH – TΔS, where ΔG is the change in Gibb’s free energy, ΔH is the change in enthalpy, ΔS is the change in entropy and T is the temperature in Kelvin. During melting transition, two systems A and B, show no difference in ΔH but B exhibits 10 % lower ΔS than A. The ratio of melting temperature of B to that of A (rounded off to 2 decimal places) is In a dye identification test, a dyed fabric is immersed in an aqueous alkaline solution of a reducing agent. The colour of the dyed fabric changes and some dye bleeds out in the solution. The correct combination of the fabric and dye is Woven fabrics can be dyed in open width form in Match the dye-fibre in Group I with the interactions in Group II. The work of adhesion (WSL) depends on surface tension (¥ LV) of the liquid and the contact angle (θ) formed on a surface is expressed as ¥ LV (1 + Cos θ). The WSL for a given fabric and a liquid is reduced to 1/3rd of the original value after oil repellent treatment. If the measured contact angle of the untreated fabric is 60º, the percent change in contact angle after the treatment is For dyeing of a polyester/cotton blended fabric in solid shade, the correct combination of dyes is A cotton fabric is printed using resist style with a reactive dye for ground colour and a chemical resist agent. Amongst the following, the correct statement(s) is/are Group I indicates chemical agents and group II indicates their functions. Match the agent with its function. Which colour indicates the presence of starch size on TEGEWA scale? Which one of them is not batch process machine? . If the spectral reflection at a given wavelength is 55% then the K/S ratio value of the measured sample is In pigment printing of cotton fabric, the pigment (along with binder) can be fixed by using The fibre property/ies that is/are governed by amorphous content is The number of amino acids in wool and silk are respectively, For production of dry-spun acrylic fibre, the suitable solvent for dope preparation is During scouring, the main purpose is to remove: Which type of finish is applied to provide anti-pilling properties? Mercerization improves the following properties of cotton: In reactive dyeing of cotton, the major role of sodium carbonate is to: A reactive dye is applied on cotton fabric by continuous method. The achieved shade on fabric is 2% on the weight of fabric. The dyebath concentration is 25 gram per litre and the % expression after padding is 100. The specific gravity of the solution is 1. The fixation % of the dye on the fabric is Sodium persulphate is used in Determine the correctness or otherwise of the following Assertion [a] and Reason [r] Assertion: Application of an optical brightening agent makes the white fabrics appear brighter. Reason: Optical brightening agents absorb energy in the visible region and radiate back in the UV region. The work of adhesion (WSL) depends on surface tension (¥ LV) of the liquid and the contact angle (θ) formed on a surface is expressed as ¥ LV (1 + Cos θ). The WSL for a given fabric and a liquid is reduced to 1/3rd of the original value after oil repellent treatment. If the measured contact angle of the untreated fabric is 60º, the percent change in contact angle after the treatment is……… A cotton fabric is dyed with reactive dye till equilibrium. If the concentration of dye in the dyebath is 0.1 gpl and partition coefficient is 500 ml/gm, then the amount of dye in the is (gm/100 gm) Which of the following is a desizing agent commonly used in cotton fabric processing?
