Dimethylol dihydroxy ethylene urea (DMDHEU) is a
Show Hint
- Crease-resist agent
- Flame retardant
- Softener
- Soil repellent
The Correct Option is A
Solution and Explanation
Step 1: Understanding the role of DMDHEU.
DMDHEU is used primarily in textile finishing to enhance the wrinkle resistance of fabrics. It works by forming cross-links between the fibers, which improves the fabric's crease resistance and overall stability. This makes it a popular choice for wrinkle-free clothing.
Step 2: Analyzing the other options.
- (B) Flame retardant: DMDHEU is not typically used as a flame retardant.
- (C) Softener: While DMDHEU can affect fabric feel, it is not used primarily as a softener.
- (D) Soil repellent: DMDHEU is not used as a soil repellent.
Step 3: Conclusion.
The correct answer is (A) Crease-resist agent, as this is the primary use of DMDHEU in textiles.
Final Answer: \[ \boxed{(A) \, \text{Crease-resist agent.}} \]
Top Questions on Finishing of cotton
- Consider the following diagram where an oil droplet is formed on a fabric immersed in water. At equilibrium, the balance of various interfacial forces acting on the droplet is given by the following equation:
\[ \gamma_{FW} = \gamma_{FO} + \gamma_{OW} \cos \theta \]
When a surfactant is added to water, assuming that \(\gamma_{OW}\) and \(\gamma_{FO}\) remain unchanged, the following happens:

- One kg bone-dry cotton fabric is padded with water to obtain 80 % wet pick up. The temperature of the wet fabric after padding is 30 °C. Assume the specific heat of water to be 1 cal/(g.°C); the latent heat of evaporation of water to be 540 cal/g and the specific heat of cotton to be 0.3 cal/(g.°C). The energy (kcal) required to dry the fabric completely (in integer) is____
